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=adminDataSourcespring.datasource.driverClassName = com.mysql.jdbc.Driverspring.datasource.url = jdbc:mysql://localhost:3306/mycms?useUnicode=true&autoReconnect=true&characterEncoding=utf-8spring.datasource.username = rootspring.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

@Configurationpublic 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。

@Configurationpublic 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;  }}
