代码结构如下:
相关代码:
package com.hhxy.lab.utils.result; import lombok.Data; import java.util.HashMap; import java.util.Map; /** * @author panlx * @version 1.0 * @date 2020-11-04 22:12 * 统一返回结果 */ @Data public class R { private Boolean success; private Integer code; private String message; private Map<String, Object> data = new HashMap<String, Object>(); private R(){} public static R ok(){ R r = new R(); r.setSuccess(true); r.setCode(ResultCode.SUCCESS); r.setMessage("成功"); return r; } public static R error(){ R r = new R(); r.setSuccess(false); r.setCode(ResultCode.ERROR); r.setMessage("失败"); return r; } public R success(Boolean success){ this.setSuccess(success); return this; } public R message(String message){ this.setMessage(message); return this; } public R code(Integer code){ this.setCode(code); return this; } public R data(String key, Object value){ this.data.put(key, value); return this; } public R data(Map<String, Object> map){ this.setData(map); return this; } }
package com.hhxy.lab.utils.result; public interface ResultCode {
//此处为返回的状态码 public static Integer SUCCESS = 200; public static Integer ERROR = 500; }
使用示例代码:
//增加仓库 @RequestMapping("/addDepot") public R addDepot(@RequestBody Depot depot){ System.out.println(depot); boolean res=depotService.save(depot); return R.ok();
//遇到多返回结果
//Map map = new HashMap();
//map.put("list",list);
//map.put("total",total);
//return R.ok().data(map);
//或者
//return R.ok().data("list",list).data("total",total); }
