使用Json-lib生成JSON文本

Json-lib测试类，如下

package com.jadyer.json;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

import net.sf.json.JSONArray;
import net.sf.json.JSONObject;

import com.jadyer.model.Student;
import com.jadyer.model.Teacher;

/**
 * Java对JSON的支持不止体现在Json-lib上面，更多信息请访问http://www.json.org
 * @see 另外还有一款更为强悍的工具包Jackson，其官方网站为http://jackson.codehaus.org
 * @see 网上曾有人做过测试，得到结论Jackson>Gson>Json-lib，详情参见http://wangym.javaeye.com/blog/738933
 * @see Json-lib可以将Java中的entity、map、collection、数组和XML转换成JSON数据格式
 * @see 注意json-lib-2.4-jdk15.jar还需要依赖其它的Jar包
 * @see 依赖ezmorph-1.0.6、commons-lang-2.5、commons-beanutils-1.8.0、commons-collections3.2.1、commons-logging-1.1.1
 * @see Json-lib的官方网站为http://json-lib.sourceforge.net

	public static void testMap(){

}

用到的实体类

package com.jadyer.model;
public class Student {
	private String name;
	private Integer age;
	/* 两个属性的getter和setter方法略 */
	public Student(){}
	public Student(String name, Integer age){
		this.name = name;
		this.age = age;
	}
}


package com.jadyer.model;
import java.util.HashSet;
import java.util.Set;
public class Teacher {
	private String name;
	private Set<Student> students = new HashSet<Student>();
	/* 两个属性的getter和setter方法略 */
}
