SpringBoot 封装返回类以及session 添加获取

1、创建返回类Result

public class Result<T>{/*错误码*/private Integer code;/*提示信息 */private String msg;/*具体内容*/private  T data;public Integer getCode() {return code;}public void setCode(Integer code) {this.code = code;}public String getMsg() {return msg;}public void setMsg(String msg) {this.msg = msg;}public T getData() {return data;}public void setData(T data) {this.data = data;}}

2、创建 ResultUtil 返回对象

public class ResultUtil {/*** 请求成功返回* @param object* @return*/public static Result success(Object object){Result Result=new Result();Result.setCode(200);Result.setMsg("请求成功");Result.setData(object);return Result;}public static Result success(){return success(null);}public static Result error(Integer code,String resultResult){Result Result=new Result();Result.setCode(code);Result.setMsg(resultResult);return Result;}
}

3、调用返回类

@RequestMapping("/link")
@RestController
public class LinkController {@Autowiredprivate LinkRepository linkRepository;@PostMapping(value = "/list")@ResponseBodypublic Result  getlinklList() {return ResultUtil.success(linkRepository.findAll());}
}

到此步 完成简单的返回类封装

 

4、session 的实现

 public String hel(HttpSession request,Model model) {request.setAttribute("name","lisi"); //设置session值String name = (String) request.getAttribute("name"); //获取session值model.addAttribute("name",name);return "index";}
