springMvc放重复提交，拦截器结合annotation

package com.geloin.spring.controller.dupsub;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;


@Target(value = { ElementType.METHOD })
@Retention(value = RetentionPolicy.RUNTIME)
public @interface Token {
	
	boolean save() default false;
	boolean remove() default false;

}

 拦截器：

package com.geloin.spring.controller.dupsub;

import java.lang.reflect.Method;
import java.util.UUID;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

import org.springframework.util.StringUtils;
import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;


public class DupsubHander extends HandlerInterceptorAdapter{

	@Override
	public boolean preHandle(HttpServletRequest request,
			HttpServletResponse response, Object handler) throws Exception {
		
		if(handler instanceof HandlerMethod){
			//将handler 转换成方法处理这方法
			HandlerMethod handlerMethod = (HandlerMethod)handler;
			//通过处理者拿到方法
			Method method = handlerMethod.getMethod();
			//通过方法拿到annotation
			Token annotation = method.getAnnotation(Token.class);
			
			if(annotation!=null){
				boolean needSaveSession = annotation.save();
				if(needSaveSession){
					HttpSession session =request.getSession();
					if(session!=null){
						session.setAttribute("token", UUID.randomUUID().toString().replaceAll("-",""));
					}
				}
				boolean needRemoveSession = annotation.remove();
				if(needRemoveSession){
                   	
					if(isPre(request)){
						response.sendRedirect("dupu.html");;
						return false;
					}
					
					request.getSession(false).removeAttribute("token");
				}
				return true;
			}
		}
		
		return super.preHandle(request, response, handler);
	}
	
	public boolean isPre(HttpServletRequest request){
		//獲取服務端的token
		if(StringUtils.isEmpty(request.getSession(false).getAttribute("token"))){
			return true;
		}
		//獲取客戶啊你單的token值
		if(StringUtils.isEmpty(request.getParameter("token"))){
			return true;
		}
		//不相同時候返回false
		if(!request.getSession(false).getAttribute("token").toString().equals(request.getParameter("token").toString())){
			return true;
		}
		
		return false;
	}
	
	
  
}

 MVC-content.xml拦截器配置：

	<mvc:interceptors>
	  <mvc:interceptor>
	    <mvc:mapping path="/**"/>
	    <bean class="com.geloin.spring.controller.dupsub.DupsubHander"></bean>
	  </mvc:interceptor>
	</mvc:interceptors>

   在提交页面:

 <input type="hidden" value="${token}" name="token"/>

 controller

package com.geloin.spring.controller;


import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;

import com.geloin.spring.controller.dupsub.Token;
import com.geloin.spring.entity.User;

@Controller
public class BinderTestController extends BaseCotroller{
	
	@Token(save=true)
	@RequestMapping(value="/productToken")
	public String test1(HttpServletRequest request){
		return "binder";
	}
	
	@Token(remove=true)
	@RequestMapping(value="/produpsub")
	public String produpsub(HttpServletRequest request,User user){
		return "Success";
	}
	
	@RequestMapping(value="/dupu")
	public String dupu(HttpServletRequest request){
		return "dupsub";
	}
	
	

}
