二、项目架构
想想还是介绍一下项目的目录结构，这样方便梳理整体的架构配置│ pom.xml ├─src │ ├─main │ │ ├─java │ │ │ └─com │ │ │ └─zsx │ │ │ │ Application.java │ │ │ │ SpringBootStartApplication.java │ │ │ │ │ │ │ ├─config │ │ │ │ │ DruidDBConfig.java │ │ │ │ │ MyStartupRunner.java │ │ │ │ │ │ │ │ │ ├─cache │ │ │ │ │ CacheConfiguration.java │ │ │ │ │ CacheUtil.java │ │ │ │ │ │ │ │ │ ├─filter │ │ │ │ │ DruidStatFilter.java │ │ │ │ │ │ │ │ │ ├─interceptors │ │ │ │ │ AuthInterceptor.java │ │ │ │ │ WebAppConfigurer.java │ │ │ │ │ │ │ │ │ ├─mybatis │ │ │ │ │ MybatisConfiguration.java │ │ │ │ │ MyBatisMapperScannerConfig.java │ │ │ │ │ │ │ │ │ ├─servlet │ │ │ │ │ DruidStatViewServlet.java │ │ │ │ │ │ │ │ │ └─swagger │ │ │ │ Swagger2.java │ │ │ │ │ │ │ ├─controller │ │ │ │ │ TestController.java │ │ │ │ │ │ │ ├─dao │ │ │ │ TuserMapper.java │ │ │ │ │ │ │ ├─entity │ │ │ │ ├─oa │ │ │ │ │ Tuser.java │ 12c82 │ │ │ │ │ │ ├─model │ │ │ │ │ UserModel.java │ │ │ │ │ │ │ │ │ └─json │ │ │ │ JsonModel.java │ │ │ │ │ │ │ ├─service │ │ │ │ │ UserService.java │ │ │ │ │ │ │ │ │ └─impl │ │ │ │ UserServiceImpl.java │ │ │ │ │ │ │ └─util │ │ │ GlobalConstant.java │ │ │ │ │ ├─resources │ │ │ │ application.yml │ │ │ │ ehcache.xml │ │ │ │ │ │ │ ├─mybatis │ │ │ │ │ mybatis-config.xml │ │ │ │ │ │ │ │ │ └─mapper │ │ │ │ TuserMapper.xml │ │ │ │ │ │ │ └─static │ │ │ ├─css │ │ │ ├─img │ │ │ └─js │ │ │ │ │ └─webapp │ │ │ index.jsp │ │ │ │ │ └─WEB-INF │ │ │ web.xml │ │ │ │ │ └─view │ │ │ login.jsp │ │ │ │ │ ├─error │ │ │ 500.jsp │ │ │ └─test │ └─java │ UtilTest.java │标准的maven项目结构，其中java下是
dao、
service、
controller，还有实体类映射
entity，其他配置
config
resources下存放mybatis的配置文件和Mapper.xml， 还有ehcache的配置文件
三、resources下的应用配置文件application.yml
#server: # port: 9090 spring: datasource: name: test url: jdbc:mysql://localhost:3306/test username: root password: root # 使用druid数据源 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat # 初始化大小，最小，最大 initialSize: 5 minIdle: 5 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false # 打开PSCache，并且指定每个连接上PSCache的大小 poolPreparedStatements: true maxPoolPreparedStatementPerConnectionSize: 20 # HTTP ENCODING http: encoding.charset: UTF-8 encoding.enable: true encoding.force: true # view mvc: view: prefix: /WEB-INF/view/ suffix: .jsp # MyBatis mybatis: # 配置类型别名 typeAliasesPackage: com.zsx.entity # dao层接口 basePackage: com.zsx.dao # 配置mapper的扫描，找到所有的mapper.xml映射文件 mapperLocations: classpath:mybatis/mapper/*.xml # 加载全局的配置文件 configLocation: classpath:mybatis/mybatis-config.xml # LOGGING logging: level: com.zsx.dao: DEBUG
四、启动应用主类文件 Application.java
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.ComponentScan;
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan // 开启通用注解扫描
@ServletComponentScan // 扫描使用注解方式的servlet
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}若需要部署到外部的tomcat容器中，则添加下面类即可。package com.zsx;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
/**
* 修改启动类，继承 SpringBootServletInitializer 并重写 configure 方法
* @author ZSX
*
*/
public class SpringBootStartApplication extends SpringBootServletInitializer {
private static final Logger logger = LoggerFactory.getLogger(SpringBootStartApplication.class);
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
}五、数据库连接池Druid的配置
package com.zsx.config;
import java.sql.SQLException;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import com.alibaba.druid.pool.DruidDataSource;
/**
* DruidDBConfig类被@Configuration标注，用作配置信息；
* DataSource对象被@Bean声明，为Spring容器所管理，
* @Primary表示这里定义的DataSource将覆盖其他来源的DataSource。
* @author ZSX
*jdbc.url=${jdbc.url}
*最新的支持方式如下:
*jdbc.url=@jdbc.url@
*/
@Configuration
public class DruidDBConfig {
// private Logger logger = LoggerFactory.getLogger(DruidDBConfig.class);
@Value("${spring.datasource.url}")
private String dbUrl;
@Value("${spring.datasource.username}")
private String username;
@Value("${spring.datasource.password}")
private String password;
@Value("${spring.datasource.driver-class-name}")
private String driverClassName;
@Value("${spring.datasource.initialSize}")
private int initialSize;
@Value("${spring.datasource.minIdle}")
private int minIdle;
@Value("${spring.datasource.maxActive}")
private int maxActive;
@Value("${spring.datasource.maxWait}")
private int maxWait;
@Value("${spring.datasource.timeBetweenEvictionRunsMillis}")
private int timeBetweenEvictionRunsMillis;
@Value("${spring.datasource.minEvictableIdleTimeMillis}")
private int minEvictableIdleTimeMillis;
@Value("${spring.datasource.validationQuery}")
private String validationQuery;
@Value("${spring.datasource.testWhileIdle}")
private boolean testWhileIdle;
@Value("${spring.datasource.testOnBorrow}")
private boolean testOnBorrow;
@Value("${spring.datasource.testOnReturn}")
private boolean testOnReturn;
@Value("${spring.datasource.poolPreparedStatements}")
private boolean poolPreparedStatements;
@Value("${spring.datasource.maxPoolPreparedStatementPerConnectionSize}")
private int maxPoolPreparedStatementPerConnectionSize;
@Value("${spring.datasource.filters}")
private String filters;
@Value("{spring.datasource.connectionProperties}")
private String connectionProperties;
@Bean // 声明其为Bean实例
@Primary // 在同样的DataSource中，首先使用被标注的DataSource
public DataSource dataSource() {
DruidDataSource datasource = new DruidDataSource();
datasource.setUrl(this.dbUrl);
datasource.setUsername(username);
datasource.setPassword(password);
datasource.setDriverClassName(driverClassName);
// configuration
datasource.setInitialSize(initialSize);
datasource.setMinIdle(minIdle);
datasource.setMaxActive(maxActive);
datasource.setMaxWait(maxWait);
datasource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);
datasource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
datasource.setValidationQuery(validationQuery);
datasource.setTestWhileIdle(testWhileIdle);
datasource.setTestOnBorrow(testOnBorrow);
datasource.setTestOnReturn(testOnReturn);
datasource.setPoolPreparedStatements(poolPreparedStatements);
datasource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);
try {
datasource.setFilters(filters);
} catch (SQLException e) {
}
datasource.setConnectionProperties(connectionProperties);
return datasource;
}
}springboot里默认使用tomcat的上传文件大小限制，即1MB，修改用下面的配置类：
import javax.servlet.MultipartConfigElement;
import org.springframework.boot.web.servlet.MultipartConfigFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MultipartConfig {
@Bean
public MultipartConfigElement multipartConfigElement(){
MultipartConfigFactory factory = new MultipartConfigFactory();
factory.setMaxFileSize("10MB");
factory.setMaxRequestSize("10MB");
return factory.createMultipartConfig();
}
}六、开启Druid的数据库监控配置
1、配置Filterimport javax.servlet.annotation.WebFilter;
import javax.servlet.annotation.WebInitParam;
import com.alibaba.druid.support.http.WebStatFilter;
/**
* 配置druid监控统计功能
* 配置Filter
* @author ZSX
*
*/
@WebFilter(filterName = "druidWebStatFilter", urlPatterns = "/*",
initParams = {
@WebInitParam(name="exclusions",value="*.js,*.gif,*.jpg,*.bmp,*.png,*.css,*.ico,/druid/*")// 忽略资源
}
)
public class DruidStatFilter extends WebStatFilter {
}2、 配置web访问的servlet
import javax.servlet.annotation.WebInitParam;
import javax.servlet.annotation.WebServlet;
import com.alibaba.druid.support.http.StatViewServlet;
/**
* 配置druid监控统计功能
* 在SpringBoot项目中基于注解的配置，如果是web.xml配置，按规则配置即可
* @author ZSX
*
*/
@WebServlet(urlPatterns = "/druid/*",
initParams = {
// @WebInitParam(name = "allow", value = "192.168.16.110,127.0.0.1"), // IP白名单 (没有配置或者为空，则允许所有访问)
// @WebInitParam(name="deny",value="192.168.16.111"), // IP黑名单 (存在共同时，deny优先于allow)
@WebInitParam(name="loginUsername",value="druid"),// 用户名
@WebInitParam(name="loginPassword",value="druid"),// 密码
@WebInitParam(name="resetEnable",value="false")// 禁用HTML页面上的“Reset All”功能
}
)
public class DruidStatViewServlet extends StatViewServlet {
}这样启动项目后在浏览器中输入
地址：端口/druid，就可以看到druid的监控web页面了
七、 拦截器配置
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class WebAppConfigurer extends WebMvcConfigurerAdapter {
/**
* 配置拦截器
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
// TODO Auto-generated method stub
// 多个拦截器组成一个拦截器链
// addPathPatterns 用于添加拦截规则
// excludePathPatterns 用户排除拦截
registry.addInterceptor(new AuthInterceptor()).addPathPatterns("/**");
super.addInterceptors(registry);
}
/**
* 添加自定义的静态资源映射
这里使用代码的方式自定义目录映射，并不影响Spring Boot的默认映射，可以同时使用。
*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
// registry.addResourceHandler("/new/**").addResourceLocations("classpath:/new/");
// registry.addResourceHandler("/**").addResourceLocations("/");
super.addResourceHandlers(registry);
}
}八、swagger发布api测试配置（可忽略）
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class Swagger2 {
@Bean
public Docket createRestApi(){
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.select()
.apis(RequestHandlerSelectors.basePackage("com.zsx.controller.api"))
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo(){
return new ApiInfoBuilder()
.title("Spring Boot中使用Swagger2构建RESTful APIs")
.description("描述")
.termsOfServiceUrl("http://zsx.com.cn")
.version("1.0")
.build();
}
}九、Mybatis配置
configuration的配置package com.zsx.config.mybatis;
import java.io.IOException;
import javax.sql.DataSource;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.DefaultResourceLoader;
import org.springframework.core.io.Resource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;
import org.springframework.transaction.annotation.TransactionManagementConfigurer;
@Configuration
@EnableTransactionManagement
public class MybatisConfiguration implements TransactionManagementConfigurer{
private static Log logger = LogFactory.getLog(MybatisConfiguration.class);
// 配置类型别名
@Value("${mybatis.typeAliasesPackage}")
private String typeAliasesPackage;
// 配置mapper的扫描，找到所有的mapper.xml映射文件
@Value("${mybatis.mapperLocations}")
private String mapperLocations;
// 加载全局的配置文件
@Value("${mybatis.configLocation}")
private String configLocation;
@Autowired
private DataSource dataSource;
// DataSource配置
// @Bean
// @ConfigurationProperties(prefix = "spring.datasource")
// public DruidDataSource dataSource() {
// return new com.alibaba.druid.pool.DruidDataSource();
// }
// 提供SqlSeesion
@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactoryBean() {
try {
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource);
// 读取配置
sessionFactoryBean.setTypeAliasesPackage(typeAliasesPackage);
Resource[] resources = new PathMatchingResourcePatternResolver()
.getResources(mapperLocations);
sessionFactoryBean.setMapperLocations(resources);
sessionFactoryBean.setConfigLocation(
new DefaultResourceLoader().getResource(configLocation));
return sessionFactoryBean.getObject();
} catch (IOException e) {
logger.warn("mybatis resolver mapper*xml is error");
return null;
} catch (Exception e) {
logger.warn("mybatis sqlSessionFactoryBean create error");
return null;
}
}
@Bean
public PlatformTransactionManager annotationDrivenTransactionManager() {
return new DataSourceTransactionManager(dataSource);
}
}扫描类配置
package com.zsx.config.mybatis;
import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
//TODO 注意，由于MapperScannerConfigurer执行的比较早，所以必须有下面的注解
@AutoConfigureAfter({MybatisConfiguration.class})
public class MyBatisMapperScannerConfig {
@Bean
public MapperScannerConfigurer mapperScannerConfigurer(){
MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
mapperScannerConfigurer.setBasePackage("com.zsx.dao");
return mapperScannerConfigurer;
}
}十、Ehcache配置
resources目录下的ehcache.xml文件
<?xml version="1.0" encoding="UTF-8"?> <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="ehcache.xsd" updateCheck="false"> <diskStore path="java.io.tmpdir"/> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="120" memoryStoreEvictionPolicy="LRU" /> <cache name="myCache" maxElementsInMemory="30" eternal="false" timeToIdleSeconds="1800" overflowToDisk="true" memoryStoreEvictionPolicy="LRU" /> </ehcache>
CacheConfiguration类
package com.zsx.config.cache;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.ehcache.EhCacheCacheManager;
import org.springframework.cache.ehcache.EhCacheManagerFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
/**
*
* @author ZSX
*/
@Configuration
@EnableCaching // 标注启动缓存
public class CacheConfiguration {
/**
* ehcache 主要的管理器
* @param bean
* @return
*/
@Bean
public EhCacheCacheManager ehCacheCacheManager(EhCacheManagerFactoryBean bean){
return new EhCacheCacheManager(bean.getObject());
}
@Bean
public EhCacheManagerFactoryBean ehCacheManagerFactoryBean(){
EhCacheManagerFactoryBean factoryBean = new EhCacheManagerFactoryBean();
factoryBean.setConfigLocation(new ClassPathResource("ehcache.xml"));
factoryBean.setShared(true);
return factoryBean;
}
}至此，所有的配置已完成，下面是一个操作数据的简单demo
十一、实体类 和 Mapper.xml 配置文件
实体类package com.zsx.entity.oa;
import java.util.Date;
public class Tuser {
private Long id;
private String userName;
private String email;
private String password;
private String mobile;
private String remark;
private String nickName;
private Integer userType;
private Long personid;
private Date register;
private Integer delFlag;
private Date createTime;
private String creator;
private Date updateTime;
private String updator;
private String isCheck;
private String cardNo;
private String workUnit;
private String position;
private String QQ;
private String weixin;
// getter setter 省略
}Mapper.xml文件
resources\mybatis\mapper\TuserMapper.xml

</mapper>十二、dao层接口
package com.zsx.dao;
import java.util.List;
import java.util.Map;
import org.apache.ibatis.annotations.Param;
import com.zsx.entity.oa.Tuser;
public interface TuserMapper {
int deleteByPrimaryKey(Long id);
int insert(Tuser record);
int insertSelective(Tuser record);
Tuser selectByPrimaryKey(Long id);
int updateByPrimaryKeySelective(Tuser record);
int updateByPrimaryKey(Tuser record);
}十三、service和controller没啥好说的，跟原先的一样，下面再提供一个单元测试的demo
import java.util.List;
import javax.persistence.EntityManager;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import com.alibaba.fastjson.JSON;
import com.zsx.Application;
import com.zsx.dao.TuserMapper;
import com.zsx.entity.pa.Tuser;
@RunWith(SpringJUnit4ClassRunner.class)
//指定我们SpringBoot工程的Application启动类
@SpringApplicationConfiguration(classes = Application.class)
//由于是Web项目，Junit需要模拟ServletContext，因此我们需要给我们的测试类加上@WebAppConfiguration
@WebAppConfiguration
public class UtilTest {
@Autowired
private TuserMapper dao;
@Test
public void test1(){
dao.selectByPrimaryKey(1L);
}
@Test
public void test2(){
// 分页助手
Page<Object> pageHelper = PageHelper.startPage(1, 10, true);
List<Tuser> findAll = dao.findAll();
long total = pageHelper.getTotal(); // 总条数
int pages = pageHelper.getPages(); // 总页数
}
}十四、补上 mybatis-config.xml
配置文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <properties> <property name="dialect" value="mysql" /> </properties> <settings> <!-- 开启驼峰匹配 --> <setting name="mapUnderscoreToCamelCase" value="true"/> <!-- 这个配置使全局的映射器启用或禁用缓存。系统默认值是true，设置只是为了展示出来 --> <setting name="cacheEnabled" value="true" /> <!-- 全局启用或禁用延迟加载。当禁用时，所有关联对象都会即时加载。 系统默认值是true，设置只是为了展示出来 --> <setting name="lazyLoadingEnabled" value="true" /> <!-- 允许或不允许多种结果集从一个单独的语句中返回（需要适合的驱动）。 系统默认值是true，设置只是为了展示出来 --> <setting name="multipleResultSetsEnabled" value="true" /> <!--使用列标签代替列名。不同的驱动在这方便表现不同。参考驱动文档或充分测试两种方法来决定所使用的驱动。 系统默认值是true，设置只是为了展示出来 --> <setting name="useColumnLabel" value="true" /> <!--允许 JDBC 支持生成的键。需要适合的驱动。如果设置为 true 则这个设置强制生成的键被使用，尽管一些驱动拒绝兼容但仍然有效（比如 Derby）。 系统默认值是false，设置只是为了展示出来 --> <setting name="useGeneratedKeys" value="false" /> <!--配置默认的执行器。SIMPLE 执行器没有什么特别之处。REUSE 执行器重用预处理语句。BATCH 执行器重用语句和批量更新 系统默认值是SIMPLE，设置只是为了展示出来 --> <setting name="defaultExecutorType" value="SIMPLE" /> <!--设置超时时间，它决定驱动等待一个数据库响应的时间。 系统默认值是null，设置只是为了展示出来 --> <setting name="defaultStatementTimeout" value="25000" /> </settings> <!-- 分页助手 --> <plugins> <plugin interceptor="com.github.pagehelper.PageHelper"> <!-- 数据库方言 --> <property name="dialect" value="mysql" /> <property name="offsetAsPageNum" value="true" /> <!-- 设置为true时，使用RowBounds分页会进行count查询 会去查询出总数 --> <property name="rowBoundsWithCount" value="true" /> <property name="pageSizeZero" value="true" /> <property name="reasonable" value="true" /> </plugin> </plugins> </configuration>
