引用json

//對象
SysUser user = null;

//對象取值 自己的業務方法
user = loginService.login(name, psd);

//對象轉obj
Object ss=JSONObject.toBean(JSONObject.fromObject(user),SysUser.class)

//obj轉JSONObject
JSONObject user_obj = JSONObject.fromObject(ss);

//json轉對象
SysUser user=(SysUser) JSONObject.toBean(user_obj,SysUser.class);
