原因：No enum constant org.apache.ibatis.type.JdbcType.com.wzh.bean.Department
<association property="department" jdbcType="com.wzh.bean.Department">
<id column="dept_id" property="deptId"/>
<result column="dept_name" property="deptName"/>
</association>
jdbcType应该为javaType
修改后如下：
<association property="department" javaType="com.wzh.bean.Department">
<id column="dept_id" property="deptId"/>
<result column="dept_name" property="deptName"/>
</association>
