目前只做到增删改查，后续有时间会继续完善

添加员工

添加成功

修改员工

删除员工

查询员工

发现没有查询，那就自己写一个吧

<!--根据员工名字模糊查询-->
<select id="queryEmployeeByName" resultType="com.dahai.pojo.Employee">
select e.id, e.lastName, e.email, e.gender, e.birth, e.did, departmentName
from employ e
inner join department d on d.id = e.did
where lastName like concat('%',#{lastName},'%')
</select>

注意

• 这里要把部门名字打印出来，不然到时候查询到的部门为null
• 千万不要在< select>< /select>标签里面写注释，不然会报SQL语句参数越界异常。

如果没有该用户则会提示error

查询成功则会打印出所查询到的所有用户

Druid后台数据监控

SQL语句监控

log4j日志

打印控制台输出内容

》到此项目的增删改查基本完成，后续有时间会在此基础上继续完善。
