sql不支持iBATIS2.3。x可以延迟加载java。整数？

Question

正在尝试延迟加载java。土地整数延迟加载属性：

<result property="foo.cnt" column="id" select="getCnt"/>

Sql语句如下所示：

<sql id="sql-getCnt">
    SELECT count(*) as cnt
    FROM  bar b INNER JOIN bar2 b2 on b.id = b2.id
    WHERE bar.id=#id#
    AND b2.workds IS NULL
</sql>

选择这样做的语句：

<select id="getCnt" parameterClass="int" resultClass="java.lang.Integer">
    <include refid="sql-getCnt"/>
</select>

设置：

<settings 
    enhancementEnabled="true"
    errorTracingEnabled="true"
    lazyLoadingEnabled="true"
    useStatementNamespaces="true"
/>

我认为延迟加载是有效的。但这就是我在日志中看到的： Select count statement goes right after first select statement - this means that lazy loading doesn't work. To ensure nothing reads object fields I force thread sleep for one minute right after querying the object.

整数的延迟加载有多慢？能做到吗

Answer 1

原因是java。整型类是final，所以cglib不能为它创建代理对象。答案是明确而简单的
