Mybatis中insert中返回主键ID的方法

<insert id="insert" parameterType="com.xxxxxx.common.model.PermissionGroup"
useGeneratedKeys="true" keyProperty="id">
.....插入SQL....
</insert>

</pre><p><pre name="code" class="html"><insert id="insert" parameterType="map"
useGeneratedKeys="true" keyProperty="id">
.....插入SQL....
</insert>

PermissionGroup group = new PermissionGroup();
.........
//调用myBatis插入数据库操作
dao.insert(group);
//myBatis自动赋值给BEAN
system.out.println(group.id);
