h2 database没法获得最后的字段子增值

h2 database无法获得最后的字段子增值
项目中使用了h2 database内存数据库，用LAST_INSERT_ID()在它本身的WEB界面里面能够获取最后的自增值，但是在项目里面就获取不到，返回的类型为null,跟整合mybatis了
sql配置为:
<select id="selectId" resultType="java.lang.Long">
<![CDATA[
SELECT LAST_INSERT_ID() as id
]]>
</select>

[解决办法]
试一试 Statement getGeneratedKeys()

Java code

String sql = "INSERT INTO tbl (col) VALUES (?)";preparedStatement = connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);preparedStatement.setString(1, col);preparedStatement.executeUpdate();generatedKeys = preparedStatement.getGeneratedKeys();if (generatedKeys.next()) {    long id = generatedKeys.getLong(1);} else {    // Throw exception?}
