偶尔看到很多零注解配置SpringMVC,其实没有根本的零注解。

1)工程图一张：

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 {        @Inject    Environment 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;    }    @Bean    public 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();    }            @Bean    public 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;    }        @Bean    public SessionLocaleResolver localeResolver() {        SessionLocaleResolver localeResolver = new SessionLocaleResolver();        return localeResolver;    }   /**    * hibernate事物    * @return    */    @Bean    public HibernateTransactionManager transactionManager() {        HibernateTransactionManager transactionManager = new HibernateTransactionManager();        transactionManager.setSessionFactory(sessionFactory());        return transactionManager;    }        /**     * ORM 映射--hibernate     * @return     */    @Bean    public HibernateAccess hibernateAccess() {        HibernateAccess hibernateAccess = new HibernateAccess();        hibernateAccess.setSessionFactory(sessionFactory());        return hibernateAccess;    }        /**     * JDBC--性能要求高场合     * @return     */    @Bean    public 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 {        @Inject    private 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)    @ResponseBody    public String testBody(Map
      
        map) {        try {            websiteServer.test();        } catch (Exception e) {            e.printStackTrace();        }        return "test";    }}

在第一个方法中，会去找test_page这个配置试图，该试图对应一个页面

第二个方法，直接返回到body中。

在page-tiles.xml与common-tiles.xml中设置对应视图位置：
