有好多好用的工具，今天小编给大家推荐个fastjson.jar.简单的将list集合转换成json数组。

在项目 pom文件中增加

<groupId>com.alibaba</groupId>

<artifactId>fastjson</artifactId>

</dependency>

不是maven 项目的话，直接将fastjspn.jar 放入项目的lib目录中即可。

以下是测试类：

package com.wd.health.api.controller;

import java.util.ArrayList;
import java.util.List;
import com.alibaba.fastjson.JSON;
import com.wd.health.sdk.customer.model.CustPhone;

public class test {
public static void main(String[] args) {
CustPhone custPhone = new CustPhone();
custPhone.setCustId(1231);
custPhone.setDesc("231321sda");
custPhone.setId(213);
custPhone.setIsDefault(1);
custPhone.setIsEnable(1);
custPhone.setPhone("21321");
List<CustPhone> list = new ArrayList<CustPhone>();
for (int i = 0; i < 3; i++) {
list.add(custPhone);
}
System.out.println(JSON.toJSON(list).toString());
}
}

输出结果为：

[{"custId":1231,"desc":"231321sda","id":213,"isDefault":1,"isEnable":1,"phone":"21321"},{"custId":1231,"desc":"231321sda","id":213,"isDefault":1,"isEnable":1,"phone":"21321"},{"custId":1231,"desc":"231321sda","id":213,"isDefault":1,"isEnable":1,"phone":"21321"}]
