Ibatis和myIbatis 返回插入的主键ID

Ibatis

 <insert id="insertAdmin">
        INSERT INTO admin ( 
            id
        <dynamic prepend="">
            <isNotNull prepend="," property="username"> username </isNotNull>
            <isNotNull prepend="," property="created_at"> created_at </isNotNull>
            <isNotNull prepend="," property="updated_at"> updated_at </isNotNull>
            <isNotNull prepend="," property="password"> password </isNotNull>

        </dynamic>
        )
        VALUES (
            #id#
        <dynamic prepend="">
            <isNotNull prepend="," property="username"> #username# </isNotNull>
            <isNotNull prepend="," property="created_at"> #created_at# </isNotNull>
            <isNotNull prepend="," property="updated_at"> #updated_at# </isNotNull>
            <isNotNull prepend="," property="password"> #password# </isNotNull>
        </dynamic>
        )

        <selectKey resultClass="int" keyProperty="id" >    
             SELECT last_insert_id() as id  
        </selectKey>    
    </insert>

myIbatis

<insert id="insert" useGeneratedKeys="true" keyProperty="id" parameterType="com.koala.blog.model.Test" >
     insert into test (id, name)
     values (#{id,jdbcType=INTEGER}, #{name,jdbcType=VARCHAR})
 </insert>

在insert中指定了keyProperty=”id”，其中id代表插入的Test对象的主键属性。

还要明确useGeneratedKeys=”true”否则也不会起作用
