SIMple Camel 应用程序不能使用 Quartz 组件答案

【问题标题】：SImple Camel application is't not working whith Quartz componentSIMple Camel 应用程序不能使用 Quartz 组件

【问题描述】：

我正在尝试使用石英组件运行一个简单的骆驼路线来安排工作。在这个例子中就像每分钟打个招呼。

这是示例路线：

public void configure() throws Exception {
    from("quartz://myname?cron=0+ *+ *+ ?+ *+ *")
    .to("log:hello");
}

当我运行应用程序时，我收到以下错误：

 An attempt was made to call a method that does not exist. The attempt was made from 
 the following location:

org.apache.camel.component.quartz.QuartzComponent.createEndpoint(QuartzComponent.java:150)

 The following method did not exist:

'org.quartz.Trigger org.quartz.Scheduler.getTrigger(java.lang.String, java.lang.String)'

 The method's class, org.quartz.Scheduler, is available from the following locations:

jar:file:/C:/Users/andre/.m2/repository/org/quartz-scheduler/quartz/2.3.2/quartz-2.3.2.jar!/org/quartz/Scheduler.class

 The class hierarchy was loaded from the following locations:

org.quartz.Scheduler: file:/C:/Users/andre/.m2/repository/org/quartz-scheduler/quartz/2.3.2/quartz-2.3.2.jar


 Action:

 Correct the classpath of your application so that it contains a single, compatible 
 version of org.quartz.Scheduler

但实际上我不明白我应该如何更正我的应用程序的类路径。这是 pom.xml：

【问题讨论】：

那个版本的保险丝看起来真的很旧。可能想尝试更新的版本。另外，不要尝试camel-quartz，而是尝试camel-quartz-starter。
感谢您的回复，但它仍然无法正常工作

【解决方案1】：

Quartz 版本在某处存在冲突，实际上是您使用的 camel-quartz 版本 (2.23.2.fuse-7_11_0-00037-redhat-00001)，预计 Quartz v1 而您最终使用的是导致问题的 Quartz v2。

您有两种方法可以解决您的问题：

继续使用 Quartz v1

在这种情况下，你必须在你的 pom 文件中强制使用 Quartz 的版本，方法是添加：

</dependency>
    <dependency>
      <groupId>org.quartz-scheduler</groupId>
      <artifactId>quartz</artifactId>
      <version>1.8.6</version>
    </dependency>
<dependency>

切换到 Quartz v2

在这种情况下，您必须将 camel-quartz 工件更改为 camel-quartz2-starter，如下所示：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-quartz2-starter</artifactId>
    <!-- use the same version as your Camel core version -->
</dependency>

然后通过指定 quartz2 而不是 quartz 来更改 Quartz 端点的 URI，如下所示：

public void configure() throws Exception {
    from("quartz2://myname?cron=0+ *+ *+ ?+ *+ *")
    .to("log:hello");
}

选择取决于您，但我绝对建议切换到 Quartz v2。
