升級到4.2.5春天已經引起了各國的石英調度啓動的問題 - 的NoSuchMethodError:org.quartz.Scheduler.getListenerManager期間()升級到4.2.5春天已經引起周圍石英調度啓動錯誤

遇到異常上下文初始化 - 取消刷新嘗試:org.springframework.beans.factory.BeanCreationException:在文件[SaPvApp-context.xml]中定義的名爲'intAppService'的bean創建時出錯:設置bean屬性'quartzScheduler時無法解析對bean'quartzScheduler'的引用「;創建嵌套的異常是org.springframework.beans.factory.Bean

CreationException:在文件[C:\ Integration Apps \ SAPV \ config \ SaPvApp-context.xml]中定義名稱爲'quartzScheduler'的Bean時創建錯誤: 調用init方法失敗;嵌套異常是java.lang.NoSuchMethodError:org.quartz.Scheduler.getListenerManager()Lorg/quartz/ListenerManager;

從POM

<dependency> 
    <groupId>org.opensymphony.quartz</groupId> 
    <artifactId>quartz</artifactId> 
    <version>1.6.5</version> 
</dependency> 

從上下文文件:

<bean name="quartzScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> 
    <property name="autoStartup" value="false" /> 
    <property name="schedulerName" value="PvScheduler" /> 
    <property name="triggers">

    <property name="cronExpression" value="10 0/30 * * * ?" /> --> 
</bean> 

編輯:嘗試升級到石英2.2.2:

/** 
* Listen for Job and Scheduler events. 
*/ 
public void listen() { 
    if (this.quartzScheduler != null) { 
     try { 
      this.quartzScheduler.addJobListener(this); 
      this.quartzScheduler.addSchedulerListener(this); 
     } 
     catch (SchedulerException e) { 
      throw new IntegrationServiceException("listen", e); 
     } 
    } 
} 

錯誤:

的方法addJobListener(QuartzTas kScheduler)是未定義的類型調度

方法addSchedulerListener(QuartzTaskScheduler)是未定義的類型調度

我張貼散佈在評論作爲一個答案,使之更容易找到這些步驟的解決方案的步驟。

一些升級到4.2.5春天有石英集成所需的步驟:

  1. 春4.2.5使用石英2.2.2,不能用石英1.x的工作,所以石英版本必須是更新。
  2. addJobListener()addSchedulerListener()方法從QuartzScheduler移動到ListenerManager,這是通過getListenerManager()方法可用。除去
  3. setJobListenerNames()方法,所以jobListenerNames不應在XML配置進行設置。

除了升級彈簧和石英我需要專門修改Java代碼周圍QuartzTaskScheduler自升級代碼沒有實現所有的抽象方法。我必須全部實現它們。這可能是因爲它的父類已經改變,加入太新抽象方法,或一些方法的簽名被改變。
