springMVC_后台自动接受map数据

jsp:

 <form action="/hello/getMap" method="post">
     <input name="mapVo['a'].name">
     <input name="mapVo['a'].password" type="password">
     <input name="mapVo['b'].name">
     <input name="mapVo['b'].password" type="password">
     <input type="submit" value="submit">
 </form>

java:

 @RequestMapping(value="/getMap",method=RequestMethod.POST)
 public void getMap(MapVo mapVo){
     Set set = mapVo.getMapVo().keySet();
     Iterator iterator = set.iterator();
     while(iterator.hasNext()){
         Object name = iterator.next();
         PersonVo p = mapVo.getMapVo().get(name);
         System.out.print(name+" "+p.getName()+" "+p.getPassword());
         System.out.println();
     }
 }

 public class MapVo {

     private Map<String,PersonVo> mapVo;

     public Map<String, PersonVo> getMapVo() {
         return mapVo;
     }

     public void setMapVo(Map<String, PersonVo> mapVo) {
         this.mapVo = mapVo;
     }


 }

 public class PersonVo {

     private String name;

     private String password;

     public String getName() {
         return name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public String getPassword() {
         return password;
     }

     public void setPassword(String password) {
         this.password = password;
     }

 }

通过以上代码，springMVC可以自动用map接受前台的数据,key是String类型的。
