Jmockdata是一款实现模拟JAVA类型或对象的实例化并随机初始化对象的数据的工具框架。

第一步：添加依赖


            
     
      com.github.jsonzou
             
     
      jmockdata
             
     
      1.0

第二步：测试使用示例

package com.zhaogang.jmockdata;import com.alibaba.fastjson.JSON;import com.alibaba.fastjson.serializer.SerializerFeature;import com.github.jsonzou.jmockdata.JMockData;import com.zhaogang.model.User;import org.junit.Test;/** * Created by weixiang.wu on 2017/9/13. */public class TestMockData {    /**     * 打印json结构     *     * @param data     */    private void print(Object data) {        System.out.println(JSON.toJSONStringWithDateFormat(data, "YYYY-MM-dd HH:mm:ss", SerializerFeature.PrettyFormat));    }    @Test    public void mockTest_mockSimpleType_mockPOJO() {        User user= JMockData.mockSimpleType(User.class);        print(user);    }}
