	/**
	 *  //常用注解快速解释：
	 *  @Controller ：用于标记在一个类上，使用它标记的类就是一个SpringMVC Controller 对象。
	 *  分发处理器将会扫描使用了该注解的类的方法，并检测该方法是否使用了@RequestMapping 注解。@Controller 
	 *  只是定义了一个控制器类，而使用@RequestMapping 注解的方法才是真正处理请求的处理器。
	 *  
	 *  @RequestMapping ：是一个用来处理请求地址映射的注解，可用于类或方法上。
	 *  用于类上，表示类中的所有响应请求的方法都是以该地址作为父路径；
	 *  用于方法上，表示在类的父路径下追加方法上注解中的地址将会访问到该方法
	 *  
	 *  @Autowired：@Autowired 注释，它可以对类成员变量、方法及构造函数进行标注，完成自动装配的工作。 通过 @Autowired的使用来消除 set ，get方法。
	 *  
	 * 
	 *  @Resource：@Autowired与@Resource都可以用来装配bean. 都可以写在字段上,或写在setter方法上。
	 *  
	 *  
	 *  @Responsebody 注解表示该方法的返回的结果直接写入 HTTP 响应正文（ResponseBody）中，
	 *  一般在异步获取数据时使用，通常是在使用 @RequestMapping 后，返回值通常解析为跳转路径，
	 *  加上 @Responsebody 后返回结果不会被解析为跳转路径，而是直接写入HTTP 响应正文中。 
     *  作用： 该注解用于将Controller的方法返回的对象，通过适当的HttpMessageConverter转换为指定格式后，写入到Response对象的body数据区。
     *   
     *
     *
	 * 
	 *  @RequestParam（value="aa" required=false）
	 *   1.可以对传入参数指定参数名
	 *   
	 *   // 下面的对传入参数指定为aa，如果前端不传aa参数名，会报错  
	 *   @RequestParam(value="aa") String inputStr 
	 *    
	 *   2、可以通过required=false或者true来要求@RequestParam配置的前端参数是否一定要传 
	 *  
	 *   3、如果@requestParam注解的参数是int类型，并且required=false，此时如果不传参数的话，会报错。原因是，required=false时，不传参数的话，
	 *   会给参数赋值null，这样就会把null赋值给了int，因此会报错。
	 *
