返回结果枚举

import lombok.AllArgsConstructor;
import lombok.Getter;

@Getter
@AllArgsConstructor
public enum ResultEnum {

    SUCCESS(200, "成功"),
    ERROR(201, "失败")
    ;
    private Integer code;
    private String message;
}

统一结果返回

import lombok.Data;
import java.io.Serializable;
import java.util.Objects;

@Data
public class Result<T> implements Serializable {

    private static final long serialVersionUID = 1L;

    private Integer code;

    private T data;

    private String message;

    private long timestamp = System.currentTimeMillis();

    private Result() {}

    public static<T> Result<T> build(T data, ResultEnum resultEnum) {
        Result<T> result = new Result<>();
        result.setCode(resultEnum.getCode());
        result.setMessage(resultEnum.getMessage());
        if (!Objects.isNull(data)) {
            result.setData(data);
        }
        return result;
    }

    public static<T> Result<T> ok(T data){
        return Result.build(data, ResultEnum.SUCCESS);
    }

    public static<T> Result<T> fail(T data){
        return Result.build(data, ResultEnum.ERROR);
    }

}
