接着看着视频案例学springboot框架

准备实体类

/*部门类*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Dept {
    private Integer id;
    private String name;
    private LocalDateTime createTime;
    private LocalDateTime updateTime;
}

/*员工类*/
@Data
@NoArgsConstructor
@AllArgsConstructor
public class Emp {
    private Integer id;
    private String username;
    private String password;
    private String name;
    private Short gender;
    private String image;
    private Short job;
    private LocalDate entrydate;
    private Integer deptId;
    private LocalDateTime createTime;
    private LocalDateTime updateTime;
}

开发规范-统一响应结果

前后端工程在进行交互时，使用统一响应结果 Result。

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Result {
    private Integer code;//响应码，1 代表成功; 0 代表失败
    private String msg;  //响应信息 描述字符串
    private Object data; //返回的数据

    //增删改 成功响应
    public static Result success(){
        return new Result(1,"success",null);
    }
    //查询 成功响应
    public static Result success(Object data){
        return new Result(1,"success",data);
    }
    //失败响应
    public static Result error(String msg){
        return new Result(0,msg,null);
    }
}
