试图延迟加载java.land.Integer。延迟加载属性:
<result property="foo.cnt" column="id" select="getCnt"/>
Sql语句是这样完成的:
<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>
选择语句是这样完成的:
<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"
/>
我希望延迟加载有效。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.
如何完成Integer的延迟加载?可以做到吗?
答案 0 :(得分:0)
原因是java.lang.Integer类是最终类,因此cglib无法为其创建代理对象。答案很简单。
