eclipse 如何搭建Spring Boot 项目 https://blog.csdn.net/a_helloword/article/details/81052834 (没测试过,顺便安利一下IDEA,真的比eclipse好用太多了顺便贴个地址eclipse转idea 地址吧https://www.geek-share.com/detail/2707421781.html)

druid连接池配置
POM
[code]<!--连接池--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.8</version> </dependency>
application.properties(配置详细讲解:https://www.jianshu.com/p/7a0f32982dcd)
[code]spring.datasource.type=com.alibaba.druid.pool.DruidDataSource spring.datasource.url=jdbc:mysql:///conference?useUnicode=true&useSSL=false&autoReconnect=true&failOverReadOnly=false&serverTimezone=GMT spring.datasource.username=admin spring.datasource.password=admin #旧版驱动为com.mysql.jdbc.Driver spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver #dataSource Pool configuration spring.datasource.initialSize=5 spring.datasource.minIdle=5 spring.datasource.maxActive=20 spring.datasource.maxWait=60000 spring.datasource.timeBetweenEvictionRunsMillis=60000 spring.datasource.minEvictableIdleTimeMillis=300000 spring.datasource.validationQuery=SELECT 1 FROM DUAL spring.datasource.testWhileIdle=true spring.datasource.testOnBorrow=false #spring.datasource.exceptionSorter=true spring.datasource.testOnReturn=false spring.datasource.poolPreparedStatements=true spring.datasource.filters=stat,wall spring.datasource.maxPoolPreparedStatementPerConnectionSize=20 spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
1) 配置监控统计功能：
[code]/**
* druid监控视图配置
* @ClassName: DruidStatViewServlet
* @author CoffeeAndIce
* @date 2017年7月24日 上午10:54:27
*/
@WebServlet(urlPatterns = "/druid/*", initParams={
@WebInitParam(name="allow",value=""),// 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="admin"),// 用户名
@WebInitParam(name="loginPassword",value="admin"),// 密码
@WebInitParam(name="resetEnable",value="true")// 禁用HTML页面上的“Reset All”功能
})
public class DruidStatViewServlet extends StatViewServlet {
private static final long serialVersionUID = 2359758657306626394L;
}
2）过滤不需要监控的后缀：
[code]/**
* 配置监控拦截器
* druid监控拦截器
* @ClassName: DruidStatFilter
*/
@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 {
}
启动类加入连接池,这个写法很多
[code]import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import javax.sql.DataSource;
@SpringBootApplication
@ServletComponentScan
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean("duridDatasource")
@ConfigurationProperties(prefix="spring.datasource")
public DataSource druidDataSource() { return new DruidDataSource(); }
}
@ServletComponentScan 注解一定要加 还有注意自己的包一定要和启动类同一级
访问http://localhost:8099/druid/login.html (账号密码都是admin)
通用Mapper插件
POM
<!--mapper --> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper-spring-boot-starter</artifactId> <version>1.2.4</version> </dependency>
application.properties
#mybatis&&通用Mapper mybatis.type-aliases-package=com.example.demo.entity.Conference mybatis.mapper-locations=classpath:mapperz/*.xml mapper.mappers=com.example.demo.dao.ConferenceMapper mapper.identity=MYSQL
在启动类上加上MapperScan注解(不要导错包)
import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.context.annotation.Bean;
import tk.mybatis.spring.annotation.MapperScan;
import javax.sql.DataSource;
@SpringBootApplication
@ServletComponentScan
@MapperScan(basePackages = { "com.example.demo.dao" })
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Bean("duridDatasource")
@ConfigurationProperties(prefix="spring.datasource")
public DataSource druidDataSource() { return new DruidDataSource(); }
}
lombck配置
lombck 源码地址https://github.com/GuoGuiRong/mybatis-generator-lombok-plugin
把源码弄下来(下载,或者用git都可以)
maven clean install 加到你的maven仓库
插件使用
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <!-- mvn mybatis-generator:generate --> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.5</version> <configuration> <verbose>true</verbose> <overwrite>true</overwrite> <configurationFile>src/main/resources/config/generatorConfig.xml</configurationFile> </configuration> <dependencies> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.45</version> </dependency> <dependency> <groupId>tk.mybatis</groupId> <artifactId>mapper</artifactId> <version>3.4.0</version> </dependency> <dependency> <groupId>com.chrm</groupId> <artifactId>mybatis-generator-lombok-plugin</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> <executions> <execution> <id>Generate MyBatis Artifacts</id> <phase>deploy</phase> <goals> <goal>generate</goal> </goals> </execution> </executions> </plugin> </plugins> </build>
添加配置文件
generatorConfig.xml使用的时候请根据项目需要自行修改对应配置
<?xml version="1.0" encoding="UTF-8"?>

<!--<property name="rootClass" value="java.io.Serializable" />-->
</javaModelGenerator>

<javaClientGenerator targetPackage="com.example.demo.dao" targetProject="src/main/java" type="XMLMAPPER">

<table tableName="conference" domainObjectName="Conference"
enableCountByExample="false" enableUpdateByExample="false"

<!--mysql 配置-->
<generatedKey column="id" sqlStatement="Mysql"/>
<!--oracle 配置-->
<!--<generatedKey column="id" sqlStatement="select SEQ_{1}.nextval from dual" identity="false" type="pre"/>-->
</table>
<!-- mvn mybatis-generator:generate -->
</context>
</generatorConfiguration>
使用mvn mybatis-generator:generate 就可以生成文件了(通用插件生成的文件我只继承了Mapper<T> 还有个可以批量操作的MySqlMapper<T>,有需要可以自己去了解)
在贴一个完整的pom文件
