我完全绝望了。这是我春天的第一天,我无法使它工作 - XMLProfileService根本没有注入,它仍然是null。如果你能给我一些暗示,我将非常感激。我在日志中没有错误。

答案 0 :(得分:2)
你创建Main2
为new Main2()
cource Spring对此一无所知。
在spring上下文中创建它。将其添加到spring-config.xml
<bean id="main2id" class="Main2">
</bean>
然后找到它。 applicationContext
上有一些允许通过id查找bean的方法。您需要将结果投射到Main2
课程。并在之后调用你的run
方法。
