SpringMVC全注解博客分类： spring

web.xml在servlet3.0里面已经被注解完全替代，但是spring里面的DispatcherServlet并没有被使用，本打算修改下源码弄成3.0的,奈何没啥时间。

这是一个标准的SpringMVC，重点是AppConfig与DBConfig，在Web.xml里面申明两个类的配置路径：


     
      
       spring
      
      
       org.springframework.web.servlet.DispatcherServlet
      
      
       
        contextConfigLocation
       
       
        com.test.commom.AppConfig
       
      
      
      
       
        contextClass
       
       
        org.springframework.web.context.support.AnnotationConfigWebApplicationContext
       
      
      
       1
      
     
     
      
       spring
      
      
       /

AppConfig：

@Configuration@ComponentScan(basePackageClasses = AppConfig.class)@EnableTransactionManagement //The code equals aop config or provider annotation transaction.@EnableAspectJAutoProxy@PropertySource({
      "classpath:site-jdbc.properties"})public class AppConfig extends DBConfig {
      /** * 国际化 * @return*/   @Bean   @Qualifier("messageSource")   public ResourceBundleMessageSource messageSource() {   ResourceBundleMessageSource bundleMessageSource = new ResourceBundleMessageSource();   bundleMessageSource.setBasename("i18n.u1wan-i18n");   bundleMessageSource.setUseCodeAsDefaultMessage(true);   return bundleMessageSource;   }      /** * file upload * @return*/   @Bean   public CommonsMultipartResolver getCommonsMultipartResolver() {   return new CommonsMultipartResolver();   }         @Bean   public SessionLocaleResolver localeResolver() {   SessionLocaleResolver localeResolver = new SessionLocaleResolver();   return localeResolver;   }      @Bean   public HessianProxyFactory loadHessianProxyFactory() {   HessianProxyFactory hessianProxyFactory = new HessianProxyFactory();   return hessianProxyFactory;   }   /** * 定义spring MVC返回显示视图 * @return*/   @Bean   public TilesViewResolver viewResolver() {   return new TilesViewResolver();   }      @Bean   public LoginInterceptor loginInterceptor() {   return new LoginInterceptor();   }      @Bean   public SystemInterceptor systemInterceptor() {   return new SystemInterceptor();   }      @Bean   public PermissionsInterceptor permissionsInterceptor() {   return new PermissionsInterceptor();   }      @Override   public void addInterceptors(InterceptorRegistry registry) {   registry.addInterceptor(loginInterceptor());   registry.addInterceptor(systemInterceptor());   registry.addInterceptor(permissionsInterceptor());   }      /** * 定义xml显示位置 * @return*/   @Bean   public TilesConfigurer tilesConfigurer() {   TilesConfigurer tilesConfigurer = new TilesConfigurer();   tilesConfigurer.setDefinitions(new String[] { "classpath*:config/tiles/page-tiles.xml", "classpath*:config/tiles/common-tiles.xml" });   return tilesConfigurer;   }      /** * 定义Spring MVC显示 * @return*/   @Bean   public CommonsMultipartResolver multipartResolver() {   CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();   return multipartResolver;   }}

DBConfig：

public class DBConfig extends DefaultWebConfig {
      @InjectEnvironment env;/** * 数据源 * @return */@Bean(destroyMethod = "close")public DataSource dataSource() {BasicDataSource dataSource = new BasicDataSource();dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driver.name"));dataSource.setUrl(env.getRequiredProperty("jdbc.writedb.proxy.url"));dataSource.setUsername(env.getRequiredProperty("jdbc.username"));dataSource.setPassword(env.getRequiredProperty("jdbc.password"));dataSource.setTestOnBorrow(true);dataSource.setValidationQuery("select 1");return dataSource;}@Beanpublic SessionFactory sessionFactory() {LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource()).scanPackages(AppConfig.class.getPackage().getName());builder.setProperty(org.hibernate.cfg.Environment.DIALECT, MySQL5Dialect.class.getName());return builder.buildSessionFactory();}@Beanpublic MongoDBAccess mongoDBAccess() {MongoDBAccess mongoDBAccess = new MongoDBAccess();mongoDBAccess.setMongoServerIpAddress(env.getRequiredProperty("mongodb.ip"));mongoDBAccess.setCollectionName(env.getRequiredProperty("mongodb.collection"));mongoDBAccess.setMongoServerPort(Integer.parseInt(env.getRequiredProperty("mongodb.port")));mongoDBAccess.setDbName(env.getRequiredProperty("mongodb.db"));mongoDBAccess.initDB();return mongoDBAccess;}@Beanpublic SessionLocaleResolver localeResolver() {SessionLocaleResolver localeResolver = new SessionLocaleResolver();return localeResolver;}   /** * hibernate事物 * @return*/@Beanpublic HibernateTransactionManager transactionManager() {HibernateTransactionManager transactionManager = new HibernateTransactionManager();transactionManager.setSessionFactory(sessionFactory());return transactionManager;}/** * ORM 映射--hibernate * @return */@Beanpublic HibernateAccess hibernateAccess() {HibernateAccess hibernateAccess = new HibernateAccess();hibernateAccess.setSessionFactory(sessionFactory());return hibernateAccess;}/** * JDBC--性能要求高场合 * @return */@Beanpublic JDBCAccess jdbcAccess() {JDBCAccess jDBCAccess = new JDBCAccess();jDBCAccess.setDataSource(dataSource());return jDBCAccess;}@Bean(name = "hibernateTransaction")public HibernateTransactionManager hibernateTransactionManager() {HibernateTransactionManager transactionManager = new HibernateTransactionManager();transactionManager.setSessionFactory(sessionFactory());return transactionManager;}}

通过类的配置，完全替代spring的配置文件，基本上不用配置文件，个人比较喜欢no配置文件的东西。

举例一个Controler:

@Controllerpublic class WebsiteController {
      @Injectprivate WebsiteServer websiteServer;@RequestMapping(value = "/website/test", method = RequestMethod.GET)public String test(Map
     
       map, WebsiteRequest request) {map.put("test", "test");return "test_page";}@RequestMapping(value = "/website/testbody", method = RequestMethod.GET)@ResponseBodypublic String testBody(Map
      
        map) {try {websiteServer.test();} catch (Exception e) {e.printStackTrace();}return "test";}}http://www.tuicool.com/articles/6fQRja6
