insert into dept (id, name, create_time, update_time) values(1,'学工部',now(),now()),(2,'教研部',now(),now()),(3,'咨询部',now(),now()), (4,'就业部',now(),now()),(5,'人事部',now(),now());
-- 员工管理(带约束)

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);
}
}
