Spring Boot 统一结果封装

Posted 2021-12-24 liuweiqc

1. ResultVo, 返回结果对象

@Data
public class ResultVo<T> 

    private Integer code;

    private String message;

    private T data;

1. ResultVoUtil, 封装返回结果

public class ResultVoUtil 

    public static<T> ResultVo<T> sucess(T data) 
        ResultVo<T> resultVo = new ResultVo<>();
        resultVo.setCode(0);
        resultVo.setMessage("成功");
        resultVo.setData(data);
        return resultVo;
    

    public static<T> ResultVo<T> sucess() 
        return sucess(null);
    

    public static ResultVo error(Integer code, String message) 
        ResultVo resultVo = new ResultVo();
        resultVo.setCode(code);
        resultVo.setMessage(message);
        resultVo.setData(null);
        return resultVo;
    

    public static ResultVo list(List data, Long count, Integer page) 
        ResultVo resultVo = new ResultVo();
        resultVo.setCode(0);
        resultVo.setMessage("成功");

        Map<String, Object> map = new HashMap<>();
        map.put("data", data);
        map.put("count", count);
        map.put("page", page);
        resultVo.setData(map);
        return resultVo;
