JAVA解析Json数据

Posted 2020-11-17 Talk is cheap. Show me the cod

JSON数据格式：

{"EventType": "event_user_create","UserId": ["123", "124", "125"],"DepId":["depId"],"CorpId": "corpid"}

JAVA解析：

public static void main(String[] args) {
    String aaa="{"EventType": "event_user_create","UserId": ["123", "124", "125"],"DepId":["depId"],"CorpId": "corpid"}";
    JSONObject object=JSONObject.fromObject(aaa);
    System.out.println(object);
    if(object.size()>0){
            Object EventType = object.get("EventType");
            System.out.println("EventType:"+EventType);
            JSONArray UserId = object.getJSONArray("UserId");
            for(int i=0;i<UserId.size();i++){
                Object object2 = UserId.get(i);
                System.out.println("UserId:"+object2);
            }
            System.out.println("UserId:"+UserId);
            JSONArray DepId = object.getJSONArray("DepId");
            System.out.println("DepId:"+DepId);
            Object CorpId = object.get("CorpId");
            System.out.println("CorpId:"+CorpId);
        }
}

结果：

{"EventType":"event_user_create","UserId":["123","124","125"],"DepId":["depId"],"CorpId":"corpid"}
EventType:event_user_create
UserId:123
UserId:124
UserId:125
UserId:["123","124","125"]
DepId:["depId"]
CorpId:corpid
