expand spring-mvc to support more type of resover

1. config the ApplicationContext

    <mvc:annotation-driven>
        <mvc:argument-resolvers>
        	<bean class="org.jhat.spring.mvc.extend.method.annotation.RequestAttributeMethodArgumentResolver"/>
    	    <bean class="org.jhat.spring.mvc.extend.method.annotation.RequestJsonParamMethodArgumentResolver"/>
      	</mvc:argument-resolvers>
    </mvc:annotation-driven>
   

2. Use org.jhat.spring.mvc.extend.bind.annotation.RequestAttribute to resolve named parameter

    URL: /jhat/user.do?user.name=Jhat&[email protected]
    
    Arg: @RequestAttribute("user") user
   

3. Use org.jhat.spring.mvc.extend.bind.annotation.RequestJsonParam to resolve named json parameter

    URL:/jhat/user.do?user={name: 'Jhat', email: '[email protected]'}
    
    Arg: @RequestJsonParam("user") user
   

4. the Validation need handle MethodArgumentNotValidException in @Controller

    @ResponseBody
    @ExceptionHandler(MethodArgumentNotValidException.class)
    public Object handleMethodArgumentNotValidException(MethodArgumentNotValidException e) {
        BindingResult result = e.getBindingResult();
        return result.getFieldError().getDefaultMessage();
    }
   

5. if need java.util.Map should use org.jhat.spring.mvc.extend.util.MapWapper to replace
