求助：spring3.2 controller方法对形如List<Object>这样的参数接收无法正确解析，该如何处理？

可以，这是几个例子

1、web用ajax提交

var jsonUserParam={"openPlatformType":"1"};
getData("${webctx}/testUser", JSON.stringify(jsonUserParam));
var jsonListParam=[{"openPlatformType":"1"},{"openPlatformType":"1"}];
getData("${webctx}/testList", JSON.stringify(jsonListParam));
var jsonMapParam={"id":{"openPlatformType":"1"}};
getData("${webctx}/testMapUser", JSON.stringify(jsonMapParam));
var jsonMapListParam={"id":[{"openPlatformType":"1"},{"openPlatformType":"1"}]};
getData("${webctx}/testMapList", JSON.stringify(jsonMapListParam));


2、Controller接收

@RequestMapping(value="/testList")
public String testList(@RequestBody List<UserPO> userList){
System.out.println("********"+userList.toString()+"*******");
return "index";
}

@RequestMapping(value="/testMapUser")
public String testMapUser(@RequestBody Map<String ,UserPO> userMap){
if(!CollectionUtils.isEmpty(userMap)){
for(String key:userMap.keySet()){
System.out.println("********"+key+":"+userMap.get(key).toString()+"*******");
}
}
return "index";
}

@RequestMapping(value="/testMapList")
public String testMapList(@RequestBody Map<String ,List<UserPO>> userMap){
if(!CollectionUtils.isEmpty(userMap)){
for(String key:userMap.keySet()){
System.out.println("********"+key+":"+userMap.get(key).toString()+"*******");
}
}
return "index";
}

@RequestMapping(value="/testUser")
public String testUser(@RequestBody UserPO user){
System.out.println("********"+user.toString()+"*******");
return "index";
}
