引入阿里fostjson库

dependencies {    compile 'com.alibaba:fastjson:1.2.23'}

LoginBeen实体类

package com.example.scxx.scbluetoothpay.been;import com.alibaba.fastjson.annotation.JSONType;/** * FileName:LoginBeen * Description: * Company:上海XX信息 * User：weijia * Email:weijiagithub@gmail.com * Time: 2017-01-03 21:09 * UpdateTime: */@JSONType(orders = { "LoginName", "LoginPwd"})public class LoginBeen {    private String LoginName;    private String LoginPwd;    public void setLoginName(String LoginName){        this.LoginName = LoginName;    }    public String getLoginName(){        return this.LoginName;    }    public void setLoginPwd(String LoginPwd){        this.LoginPwd = LoginPwd;    }    public String getLoginPwd(){        return this.LoginPwd;    }}

//fastjson将实体类对象转换为JSON(loginUsername，loginUserpwd是获取键盘录入获取的数据)

                    //fastjson将实体类对象转换为JSON                    LoginBeen loginBeen = new LoginBeen();                    loginBeen.setLoginName(loginUsername);                    loginBeen.setLoginPwd(loginUserpwd);                    String jsonstring = JSON.toJSONString(loginBeen);                    System.out.println("jsonstring--------"+jsonstring);
