引用方法
在需要返回结果的接口类中
private RespsonData rd = new RespsonData("success");// 通用返回JSON对象
接口使用@ResponseBody注解,会自动把结果转换成json格式
此为测试接口,成功返回的是success,失败返回的是error的json格式
private RespsonData rd = new RespsonData("success");
@RequestMapping(method={RequestMethod.POST}, value="/XXXXXX")
@ResponseBody
protected Object getXXXXXXX(HttpServletRequest request, HttpServletResponse response) throws Exception{
try {
} catch (Exception e) {
rd.setRes("error");
throw e;
}
return rd;
}
