          "Mubshar Pribno"
        ]
      }
}

请建议我在java代码中创建这种类型的Json格式请帮帮我

Answer 1

GSON是Google的一个Java库，用于将Java对象转换为JSON。您只需将Java对象传递给库函数，它就会返回一个JSON字符串。

下载：http://code.google.com/p/google-gson/

Answer 2

我建议您使用Jackson。

This is cool tutorial

Answer 3

对于上述json，您必须拥有以下课程：

<强> Example.java

package com.example;
import javax.annotation.Generated;
import com.google.gson.annotations.Expose;

public class Example {

@Expose
private To to;
public To getTo() {
return to;
}
public void setTo(To to) {
this.to = to;
}
}

<强> To.java

package com.example;

import java.util.ArrayList;
import java.util.List;
import javax.annotation.Generated;
import com.google.gson.annotations.Expose;

public class To {

@Expose
private List<String> names = new ArrayList<String>();
@Expose
private List<String> callerIds = new ArrayList<String>();
@Expose
private List<String> captions = new ArrayList<String>();

public List<String> getNames() {
return names;
}
public void setNames(List<String> names) {
this.names = names;
}
public List<String> getCallerIds() {
return callerIds;
}
public void setCallerIds(List<String> callerIds) {
this.callerIds = callerIds;
}
public List<String> getCaptions() {
return captions;
}
public void setCaptions(List<String> captions) {
this.captions = captions;
}

}

然后将此类转换为json字符串，如下所示：

Gson gson = new Gson();
To myTo=new To();
myTo.setNames(...);
myTo.setCallerIds(...);
myTO.setCaptions(...);
Example exm=new Example();
exm.setTo(myTo);
System.out.println(gson.toJson(exm));

你可以在java代码中创建一个json，因为你需要在java项目 json-simple-1.1.1.jar 中导入jar，你可以参考链接知道如何在java Click here to know how to create a json in java

中开发一个json

JsonArray转换为java代码
