项目common结构：

CommonResponse写法

import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonInclude;
import lombok.Getter;

import java.io.Serializable;

@Getter
@JsonInclude(JsonInclude.Include.NON_NULL)
public class CommonResponse implements Serializable {

    private int status;
    private String msg;
    private T data;

    private CommonResponse(int status){
        this.status=status;
    }
    private CommonResponse(int status,String msg){
        this.status=status;
        this.msg=msg;
    }
    private CommonResponse(int status,String msg,T data){
        this.status=status;
        this.msg=msg;
        this.data=data;
    }
    private CommonResponse(int status,T data){
        this.status=status;
        this.data=data;
    }

    @JsonIgnore
    public boolean isSuccess(){
        return this.status == ResponseCode.SUCCESS.getCode();
    }
    public static  CommonResponse  createForSuccess(){
        return new CommonResponse(ResponseCode.SUCCESS.getCode());
    }
    public static  CommonResponse  createForSuccess(T data){
        return new CommonResponse(ResponseCode.SUCCESS.getCode(),data);
    }
    public static  CommonResponse  createForSuccessMessage(String msg){
        return new CommonResponse(ResponseCode.SUCCESS.getCode(),msg);
    }
    public static  CommonResponse  createForSuccess(String msg,T data){
        return new CommonResponse(ResponseCode.SUCCESS.getCode(),msg,data);
    }
    public static  CommonResponse  createForError(){
        return new CommonResponse(ResponseCode.ERROR.getCode(),ResponseCode.ERROR.getDescription());
    }
    public static  CommonResponse  createForError(String msg){
        return new CommonResponse(ResponseCode.ERROR.getCode(),msg);
    }
    public static  CommonResponse  createForError(int code,String msg){
        return new CommonResponse(code,msg);
    }
}

ResponseCode(枚举)的写法

import lombok.Getter;

@Getter
public enum ResponseCode {
    SUCCESS(0,"SUCCESS"),
    ERROR(1,"ERROR"),
    NEED_LOGIN(10,"NEED_LOGIN"),
    ILLEGAL_ARGUMENT(2,"ILLEGAL_ARGUMENT");

    private final int code;
    private final String description;

    ResponseCode(int code,String description){
        this.code=code;
        this.description = description;
    }

}
