springmvc 数据绑定时，如何自动接受复合对象（已封装Bean）

如：
Bean{

map<Long,List<T>> map;

}
Bean{

map<Object,List<T>> map;

}

Bean{

map<Long,map<Integer,Integer>> map;

}

Bean{

map<Long,map<Integer,List<T>>> map;

}

....
求大神解答

Answer 1

It is not possible to directly specify the parameter as Map in the Controller. You need to encapsulate a Bean to receive the data. You can watch this video: http://www.imooc.com/learn/558

Answer 2

Post json on the front end, and just use @RequestBody as the backend controller parameter

Answer 3

Post json from the front end, and just use @RequestBody as the backend controller parameter.
I agree with the answer above. Use post request and @RequestBody will automatically parse it
