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。
