Question

我正在尝试将项目从spring 2.5.6和java 6迁移到spring 4.2和java 8，在wildfly 9服务器上运行。我根据讨论和示例更新了SimpleTriggerBean对SimpleTriggerFactoryBean的引用（例如http://websystique.com/spring/spring-4-quartz-scheduler-integration-example/）

但是，当我运行应用程序时，我收到以下错误;

WARN [org.springframework.web.context.support.XmlWebApplicationContext]（ServerService线程池 - 66）上下文初始化期间遇到异常 - 取消刷新尝试：org.springframework.beans.factory.BeanCreationException：使用名称创建bean时出错＆＃39; invalSvc＆＃39;在ServletContext资源中定义[/WEB-INF/classes/resources/spring/spring-cfg.xml]：无法解析对bean的引用＆＃39; changeHelper＆＃39;设置bean属性＆＃39; changeHelper＆＃39 ;;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为＆＃39; changeHelper＆＃39;的bean时出错在ServletContext资源[/WEB-INF/classes/resources/spring/spring-cfg.xml]中定义：无法解析对bean的引用＆＃39; invalRpcHelper＆＃39;设置bean属性＆＃39; invalRpcHelper＆＃39 ;;嵌套异常是org.springframework.beans.factory.BeanCreationException：创建名为＆＃39; invalRpcHelper＆＃39;的bean时出错。在ServletContext资源中定义[/WEB-INF/classes/resources/spring/spring-cfg.xml]：bean的初始化失败;嵌套异常是java.lang.NoClassDefFoundError：org / springframework / scheduling / quartz / SimpleTriggerBean

我正在运行的代码没有任何对SimpeTriggerBean的可视化引用，我无法弄清楚为什么会发生这种情况。 SimpleTriggerFactoryBean应该在Quartz 1.x和2.x中都有效。

我已经测试了弹簧和石英的多个版本。

如果我从retryHandlerImpl中删除所有引用（包括inputController，scheduleFileReaderJob和fileTrigger），则仍会抛出异常。

<bean name="retryHandlerImpl" class="com.myproject.code.rpc.vscall.RetryHandlerImpl">
/*
    <property name="passwordManager" ref="passwordManager" />
    <property name="signal" ref="signal" /> 
    <property name="handleToSTB" ref="fileTrigger" />  
    <property name="serverLoader" ref="serverLoader" />
    <property name="serializeHelper" ref="serializeHelper" /> 
*/
</bean>

<bean name="invalRpcHelper" class="com.myproject.code.rpc.calls.InvalRpcHelperImpl">
    //<property name="rpcHelper" ref="retryHandlerImpl" />
</bean>

任何关于为什么存在这种依赖关系的想法或想法，或者哪个版本的库将是神奇的组合，都是最受欢迎的。

致以最诚挚的问候，

Answer 1

<强>解决方案：在从ant升级到maven的过程中，出现了一个错误，并且编译版本的类放在WEB-INF目录中。

这导致运行时出现一些离散的冲突。只有不加载所涉及的类才会让应用程序绕过问题，从而导致可疑症状。

从WEB-INF中删除文件夹解决了这个问题。

使用SimpleTriggerFactoryBean
