那些遇到过的问题

当删除未使用的bean时,Spring抛出'IllegalStateException:ApplicationEventMulticaster未初始化'

Ada*_*mes 5 java spring tomcat destroy spring-bean

我最近在DAO类中删除了一个未使用的Injected bean,虽然应用程序按预期运行,但它在启动时在Tomcat中导致了以下堆栈跟踪错误.当我替换这个未使用的自动连线bean定义时,它似乎消失了,这让我觉得它在某个方面需要在destroy函数中,但是destroy这个类没有指定的函数.所以我知道它在某种程度上被引用,但我不知道如何,并且启用DEBUGspring级别登录并没有提供更多信息.

现在删除的Service类确实引用了这个DAO类,但是DAO类(现在)并没有在任何地方引用Service类.我不确定我错过了什么Spring魔法来解决这个问题.

编辑:使用弹簧4.2.3.RELEASE

EIDT 2:CustomFormService使用注释(@Service)创建类,而使用XML配置创建DAO类.当我切换到使用@Component注释和包扫描CustomDataFormDAO类时,堆栈跟踪消失了,但我不知道为什么.
