利用Mybatis 的 selectKey来获得：

1. <!-- 添加部门 返回部门ID -->  
2. <insert id="addDept" parameterType="com.demo.model.Department" keyProperty="id">  
3.     <selectKey keyProperty=‘id‘ resultType=‘int‘ order=‘AFTER‘  >  
4.         select LAST_INSERT_ID();  
5.     </selectKey>  
6.      insert into department(<include refid="departmentAllField"/>)   
7.         values(#{departmentId},#{departmentName},#{departmentManagerName},#{companyId});  
8.  </insert> 
   

或

1. <insert id="addDept" parameterType="com.demo.model.Department" useGeneratedKeys="true" keyProperty="id">  
2.   insert into department(<include refid="departmentAllField"/>)   
3.    values(#{departmentId},#{departmentName},#{departmentManagerName},#{companyId});  
4. </insert>
   

<insert id="insert" keyColumn="id" keyProperty="id" parameterType="com.edu.archive.business.domain.grade.pojo.model.ApplicationRecord" useGeneratedKeys="true">

  insert into bj_application_record (parent_id, class_no, student_name, 
    kinsfolk_relation, `status`, refuse_remark, 
    create_time, update_time, version
    )
  values (#{parentId,jdbcType=INTEGER}, #{classNo,jdbcType=VARCHAR}, #{studentName,jdbcType=VARCHAR}, 
    #{kinsfolkRelation,jdbcType=VARCHAR}, #{status,jdbcType=TINYINT}, #{refuseRemark,jdbcType=VARCHAR}, 
    #{createTime,jdbcType=TIMESTAMP}, #{updateTime,jdbcType=TIMESTAMP}, #{version,jdbcType=INTEGER}
    )
</insert>
