实习中学到的代码规范

1：控制层的代码规范，这样返回前端的数据都是可以解析的。

 @RequestMapping(value = "/login/change")
    public JsonBean login(@RequestParam("Id") long Id,
                                 @RequestParam("Status") String Status,
                                 @RequestParam("Opinion") String Opinion) {
        JsonBean jsonBean = new JsonBean();
        try {
            RequireInfoBeanSv.changeStatus(requireId, requireStatus, reviewOpinion);
            jsonBean.success("成功");
        } catch (Exception e) {
            e.printStackTrace();
            jsonBean.fail("失败");
        }
        return jsonBean;
    }
