更改骆驼版本时未在weblogic中部署战争

Question

我有使用 apache camel 版本 2.13.2 的 spring 项目，当我尝试将版本更新为 2.18.1 时。我的战争无法开始并引发以下错误 -

是否有任何具体原因导致这种情况发生，或者我应该看什么以及在哪里看，因为我真的不知道为什么 camel 的更改导致找不到 spring 的课程？

除此之外，我在 java 配置中创建的所有路由都不起作用，并且对于消耗来自给定端点的消息的所有路由都抛出像 consumer not found for endpoint 这样的异常，但在用 xml 编写时似乎同样有效。这有什么原因吗？我正在使用camel 2.13.2，路由的java配置是通过扩展RouteBuilder完成的，我还有其他已经用xml编写的路由，xml已经添加到contextConfigLocation中。是否与在 contextConfig 中添加 xml 有某种关系？

Answer 1

camel-jms:2.18.1 组件使用 spring-jms 和版本 4.3.4.RELEASE。需要升级到spring4.3.4.RELEASE或者将camel-jms组件迁移到camel-sjms，不使用spring。您可以在camel-parent-2.18.1.pom中找到所有相关的依赖项

如果您使用 Maven，保持依赖关系一致的最佳方法是使用 BOM：

<dependencyManagement> 
  <dependnecies> 
    <dependency> 
      <groupId>org.apache.camel</groupId> 
      <artifactId>camel-parent</artifactId> 
      <version>2.18.1</version> 
      <type>pom</type> 
      <scope>import</scope> 
    </dependency> 
  </dependnecies> 
</dependencyManagement> 

然后排除您在应用程序中使用的所有与骆驼和弹簧相关的依赖项的版本。

<dependency> 
    <groupId>org.apache.camel</groupId> 
    <artifactId>camel-core</artifactId> 
</dependency>
...
<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-core</artifactId> 
</dependency>
