其他几个层的你怎么写

<insert id="insertOneMessage" parameterType="com.him.entity.Message" >

INSERT INTO message(command,description,content) VALUES(#{command},#{description},#{content})

</insert>

SqlSession sqlSession = null;

try {

sqlSession = DBAccess.getSqlSession();

sqlSession.insert("Message.insertOneMessage", message);

sqlSession.commit();

} catch (IOException e) {

e.printStackTrace();

return null;

}finally {

if(sqlSession != null) {

sqlSession.close();

}

}
