The [Json-lib framework] makes conversion between Java objects, JSON, and XML no longer difficult __js

Json-lib can convert a Java object into a JSON-formatted string or convert a Java object into an XML-formatted document, either converting a JSON string into a Java object or converting an XML string into a Java object.

First, preparatory work

 

1, the first to go to the official Download Json-lib Toolkit

Download Address:

http://sourceforge.net/projects/json-lib/files/json-lib/json-lib-2.4/

The latest is the 2.4 version, which is used in the example V2.3;json-lib also requires the following dependent packages:

Jakarta Commons-lang 2.5

Jakarta commons-beanutils 1.8.0

Jakarta commons-collections 3.2.1

Jakarta commons-logging 1.1.1

Ezmorph 1.0.6

Official website: http://json-lib.sourceforge.net/

Then add the following jar package to the project:

Of course, you can also use the 2.4 json-lib library.

You can look at the official examples here:

Http://json-lib.sourceforge.net/usage.html

Because the examples in this presentation require JUnit tools, you will also need to add JUnit jar files, version 4.8.2 version, download address: https://github.com/KentBeck/junit/downloads

If you don't know what JSON is. Then you should be able to see http://www.json.org/json-zh.html.

2, the code to convert the JavaBean is as follows:

Package com.hoo.entity;

public class Student {

    private int id;

    private String name;

    Private String Email;

    Private String address;

    private birthday birthday;

    Setter, getter

    Public String toString () {

        return this.name + "#" + this.id + "#" + this.address + "#" + This.birthday + "#" + this.email;

    }

}

Birthday.java

Package com.hoo.entity;

public class Birthday {

    Private String birthday;

    Public birthday (String birthday) {

        Super ();

        This.birthday = Birthday;

    }

    Setter, getter

    Public birthday () {}

    @Override

    Public String toString () {

        return this.birthday;

    }

}

Notice that the getter and setter methods above are omitted and built by themselves.

3, the new Jsonlibtest test class, the basic code is as follows:

Package com.hoo.test;

Import java.lang.reflect.InvocationTargetException;

Import java.util.ArrayList;

Import java.util.Collection;

Import Java.util.Date;

Import Java.util.HashMap;

Import Java.util.Iterator;

Import java.util.List;

Import Java.util.Map;

Import Java.util.Set;

import Net.sf.json.JSON;
