SpringMVC中如何将MultiActionController和CommandController结和使用

java 代码
 

   1. package com.betop.probe.controller.study; 
   2.  
   3. import java.util.HashMap; 
   4. import java.util.Map; 
   5.  
   6. import javax.servlet.http.HttpServletRequest; 
   7. import javax.servlet.http.HttpServletResponse; 
   8.  
   9. import org.springframework.validation.BindException; 
  10. import org.springframework.web.bind.ServletRequestDataBinder; 
  11. import org.springframework.web.servlet.ModelAndView; 
  12. import org.springframework.web.servlet.mvc.AbstractCommandController; 
  13.  
  14. import com.betop.probe.domain.MasterUser; 
  15.  
  16. public class UserMultiActionController3 extends AbstractCommandController{ 
  17.      
  18.     public UserMultiActionController3(){ 
  19.         this.setCommandClass(MasterUser.class); 
  20.     } 
  21.      
  22.     public ModelAndView demo1(HttpServletRequest req, HttpServletResponse resp)throws Exception { 
  23.          
  24.         Map model = new HashMap(); 
  25.         model.put("message", "这是MultiActioncontroller的第三种配置!"); 
  26.         return new ModelAndView("study/MultiActionControllerView3.vm", model); 
  27.     } 
  28.      
  29.     public ModelAndView demo2(HttpServletRequest req, HttpServletResponse resp)throws Exception{ 
  30.          
  31.          
  32.         MasterUser user = getCommand(req, resp); 
  33.          
  34.         Map model = new HashMap(); 
  35.          
  36.         model.put("user", user); 
  37.          
  38.         return new ModelAndView("study/result.vm", model); 
  39.         //return super.handleRequest(req, resp); 
  40.     } 
  41.      
  42.     private MasterUser getCommand(HttpServletRequest req, HttpServletResponse resp) throws Exception{ 
  43.          
  44.         MasterUser command = (MasterUser)getCommand(req); 
  45.         ServletRequestDataBinder binder = bindAndValidate(req, command); 
  46.         BindException errors = new BindException(binder.getBindingResult()); 
  47.          
  48.         return command; 
  49.     } 
  50.  
  51.     @Override 
  52.     protected ModelAndView handle(HttpServletRequest request, 
  53.             HttpServletResponse response, Object command, BindException errors) 
  54.             throws Exception { 
  55.         // TODO Auto-generated method stub 
  56.         return null; 
  57.     } 
  58.  
  59. }
