Sprigmvc项目转为springboot的方法

是否有老掉牙的springmvc项目，想转成springboot项目，看这个文章就对了。

说明

如果你的项目连maven项目都不是，请自行转为maven项目，在按照本教程进行。

本教程适用于spring+springmvc+mybatis+shiro的maven项目。

1.修改pom文件依赖

删除之前的spring依赖，添加springboot依赖

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<!-- 这个是剔除掉自带的 tomcat部署的-->
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<!-- tomcat容器部署 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!--<scope>compile</scope>-->
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
<!-- 支持 @ConfigurationProperties 注解 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
</dependencies>

添加springboot构建插件

<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.5.9.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>

2.添加application启动文件

注意，如果Application在controller，service，dao的上一层包里，无需配置 @ComponentScan ,

否则，需要指明要扫描的包。

@SpringBootApplication
//@ComponentScan({"com.cms.controller","com.cms.service","com.cms.dao"})
public class Applicationextends SpringBootServletInitializer{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
return application.sources(Application.class);
}
public static void main(String[] args)throws Exception {
SpringApplication.run(Application.class, args);
}
}

3.添加springboot配置文件

在resources下面添加application.properties文件

添加基本配置
#默认前缀
server.contextPath=/
# 指定环境
spring.profiles.active=local
# jsp配置
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
#log配置文件
logging.config=classpath:logback-cms.xml
#log路径
logging.path=/Users/mac/work-tommy/cms-springboot/logs/
#数据源
spring.datasource.name=adminDataSource
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/mycms?useUnicode=true&autoReconnect=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = 123456

4.使用@Configuration注入配置

注入mybatis配置,分页插件请自主选择

@Configuration
@MapperScan(basePackages = "com.kuwo.dao",sqlSessionTemplateRef = "adminSqlSessionTemplate")
public class AdminDataSourceConfig{
@Bean(name = "adminDataSource")
@ConfigurationProperties(prefix = "spring.datasource")
@Primary
public DataSource adminDataSource(){
return DataSourceBuilder.create().build();
}
@Bean(name = "adminSqlSessionFactory")
@Primary
public SqlSessionFactory adminSqlSessionFactory(@Qualifier("adminDataSource")DataSource dataSource)throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
//分页插件
// PageHelper pageHelper = new PageHelper();
PagePlugin pagePlugin = new PagePlugin();
// Properties props = new Properties();
// props.setProperty("reasonable", "true");
// props.setProperty("supportMethodsArguments", "true");
// props.setProperty("returnPageInfo", "check");
// props.setProperty("params", "count=countSql");
// pageHelper.setProperties(props);
//添加插件
bean.setPlugins(new Interceptor[]{pagePlugin});
// 添加mybatis配置文件
bean.setConfigLocation(new DefaultResourceLoader().getResource("classpath:mybatis/mybatis-config.xml"));
// 添加mybatis映射文件
bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/system/*.xml"));
return bean.getObject();
}
@Bean(name = "adminTransactionManager")
@Primary
public DataSourceTransactionManager adminTransactionManager(@Qualifier("adminDataSource")DataSource dataSource){
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "adminSqlSessionTemplate")
@Primary
public SqlSessionTemplate adminSqlSessionTemplate(@Qualifier("adminSqlSessionFactory")SqlSessionFactory sqlSessionFactory)throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}

添加Interceptor配置,注意addInterceptor的顺序，不要搞乱了

@Configuration
public class InterceptorConfigurationextends WebMvcConfigurerAdapter{
@Override
public void addInterceptors(InterceptorRegistry registry){
registry.addInterceptor(new LoginHandlerInterceptor());
}
}

添加shiro配置文件

注意：本来使用redis做session缓存，但是和shiro集成发现一个问题，user对象存储以后，从shiro中获取后，无法进行类型转换，所以暂时放弃了redis做session缓存。

@Configuration
public class ShiroConfiguration{
@Value("${spring.redis.host}")
private String host;
@Value("${spring.redis.port}")
private int port;
@Value("${spring.redis.timeout}")
private int timeout;
@Bean
public static LifecycleBeanPostProcessor getLifecycleBeanPostProcessor(){
return new LifecycleBeanPostProcessor();
}
/**
* ShiroFilterFactoryBean 处理拦截资源文件问题。
* 注意：单独一个ShiroFilterFactoryBean配置是或报错的，因为在
* 初始化ShiroFilterFactoryBean的时候需要注入：SecurityManager
*
Filter Chain定义说明
1、一个URL可以配置多个Filter，使用逗号分隔
2、当设置多个过滤器时，全部验证通过，才视为通过
3、部分过滤器可指定参数，如perms，roles
*
*/
@Bean
public ShiroFilterFactoryBean shiroFilter(SecurityManager securityManager){
System.out.println("ShiroConfiguration.shirFilter()");
ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
// 必须设置 SecurityManager
shiroFilterFactoryBean.setSecurityManager(securityManager);
// 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
shiroFilterFactoryBean.setLoginUrl("/login_toLogin");
// 登录成功后要跳转的链接
shiroFilterFactoryBean.setSuccessUrl("/usersPage");
//未授权界面;
shiroFilterFactoryBean.setUnauthorizedUrl("/403");
//拦截器.
Map<String,String> filterChainDefinitionMap = new LinkedHashMap<>();
//配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了
filterChainDefinitionMap.put("/logout", "logout");
filterChainDefinitionMap.put("/login_toLogin", "anon");
filterChainDefinitionMap.put("/login_login", "anon");
filterChainDefinitionMap.put("/static/login/**","anon");
filterChainDefinitionMap.put("/static/js/**","anon");
filterChainDefinitionMap.put("/uploadFiles/uploadImgs/**","anon");
filterChainDefinitionMap.put("/code.do","anon");
filterChainDefinitionMap.put("/font-awesome/**","anon");
//<!-- 过滤链定义，从上向下顺序执行，一般将 /**放在最为下边 -->:这是一个坑呢，一不小心代码就不好使了;
//<!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->
filterChainDefinitionMap.put("/**", "authc");
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
return shiroFilterFactoryBean;
}
@Bean
public SecurityManager securityManager(){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//设置realm.
securityManager.setRealm(myShiroRealm());
// 自定义缓存实现 使用redis
//securityManager.setCacheManager(cacheManager());
// 自定义session管理 使用redis
securityManager.setSessionManager(sessionManager());
return securityManager;
}
@Bean
public ShiroRealm myShiroRealm(){
ShiroRealm myShiroRealm = new ShiroRealm();
// myShiroRealm.setCredentialsMatcher(hashedCredentialsMatcher());
return myShiroRealm;
}
}
/**
* 开启shiro aop注解支持.
* 使用代理方式;所以需要开启代码支持;
* @param securityManager
* @return
*/
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager){
AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
return authorizationAttributeSourceAdvisor;
}
/**
* 配置shiro redisManager
* 使用的是shiro-redis开源插件
* @return
*/
public RedisManager redisManager(){
RedisManager redisManager = new RedisManager();
redisManager.setHost(host);
redisManager.setPort(port);
redisManager.setExpire(1800);
redisManager.setTimeout(timeout);
// redisManager.setPassword(password);
return redisManager;
}
/**
* cacheManager 缓存 redis实现
* 使用的是shiro-redis开源插件
* @return
*/
public RedisCacheManager cacheManager(){
RedisCacheManager redisCacheManager = new RedisCacheManager();
redisCacheManager.setRedisManager(redisManager());
return redisCacheManager;
}
/**
* RedisSessionDAO shiro sessionDao层的实现 通过redis
* 使用的是shiro-redis开源插件
*/
@Bean
public RedisSessionDAO redisSessionDAO(){
RedisSessionDAO redisSessionDAO = new RedisSessionDAO();
redisSessionDAO.setRedisManager(redisManager());
return redisSessionDAO;
}
@Bean
public DefaultWebSessionManager sessionManager(){
DefaultWebSessionManager sessionManager = new DefaultWebSessionManager();
// sessionManager.setSessionDAO(redisSessionDAO());
return sessionManager;
}
}
