前后端分离Java统一响应返回格式

一共需要两个类，一个专门用来存储返回的状态码，一个专门用来存储返回结果

ResultCode类

public class ResultCode {
    public static Integer SUCCESS = 200;

    public static Integer ERROR = 500;

    public static Integer FORBIDDEN = 403;

    public static Integer UNAUTHORIZED = 401;
}

Result类

@Data //lombok注解
public class Result {

    //返回码
    private Integer code;

    //返回消息
    private String message;

    //返回数据
    private Map<String, Object> data = new HashMap<String, Object>();

    public Result(){}

    public Result message(String message){
        this.setMessage(message);
        return this;
    }

    public Result code(Integer code){
        this.setCode(code);
        return this;
    }
    
    public Result data(String key, Object value){
        this.data.put(key, value);
        return this;
    }

    public Result data(Map<String, Object> map){
        this.setData(map);
        return this;
    }
}

使用示例

	@RequestMapping("/get")
    public Result get(){
        HashMap map = new HashMap();
        map.put("username","admin");
        map.put("password","123456");
        Result r = new Result();
        r.code(ResultCode.SUCCESS).message("成功访问").data(map);
        return r;
    }
