Java解析对象

Question

I hava a javascript object that im passing back to java via ajax:

var jsonData = {   
        "testJson" : "abc",  
        "userId" : "123" 
}; 

When I println the map it looks like:

key: jsondata value:[object Object]

How can I properly parse the object?

Answer 1

You can use GSON in java:

class MyObject() {
  String testJson;
  String userId;

  public void setTestJson(String testJson) {
    this.testJson=testJson;
  }
  public String getTestJson() {
    return testJson;
  }
  ... Same for userId
}

And then create a GSON object:

class SomeClass {
  public void parseMyJson(String json) {
    Gson gson=new Gson();
    MyObject mo=gson.fromJson(json,MyObject.class);
  }
}

In which mo now contains you json object with just the use of getters and setters
