java将json作为字符串传递

Question

对于Json体，如

{
    "firstName": "hello",
    "lastName": "abc"
}

我写的是

JSONObject body = new JSONObject();

    
body.put("firstName", "hello");
body.put("lastName", "abc");

然后将body转换为string，将其作为string参数传递

我怎样才能用同样的方式写出身体的反应呢

{
    "class": {
        "firstName": "hello",
        "lastName": "abc"
    }
}

之后我需要将json转换为字符串

Answer 1

创建一个类：

public class DataSource {
    private String firstName;
    private String lastName;
    //Constructor, getter, setter
}

然后：

JSONObject body = new JSONObject();
DataSource data = new DataSource();
data.setFirstName("bla");
data.setLastName("bla bla");
body.put("class", data );

Answer 2

我认为这应该能奏效

    JSONObject innerBody = new JSONObject();
    innerBody.put("firstName", "hello");
    innerBody.put("lastName", "abc");

    JSONObject outerBody = new JSONObject();
    outerBody.put("class",innerBody);
