java - 在更改 Camel 版本时，War 未部署在 weblogic 中

Question

我有一个使用 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 war 无法启动并抛出以下错误 -

Target state: deploy failed on Server Common

是否有任何具体原因发生这种情况，或者我应该看什么以及在哪里，因为我真的不知道为什么 camel 的更改会导致找不到 spring 的类？

除此之外，我在java配置中创建的所有路由都不起作用，并且对于使用来自给定端点的消息的所有路由抛出诸如consumer not find for endpoint之类的异常，但似乎同样适用当用xml编写时。这有什么原因吗？我正在使用camel 2.13.2，并且路由的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，并且xml已添加到contextConfigLocation中。它是否与在 contextConfig 中添加 xml 有关？

camel-jms:2.18.1 组件使用 spring-jms 版本为 4.3.4.RELEASE。您需要升级到 spring 4.3.4.RELEASE 或将 camel-jms 组件迁移到 camel-sjms，后者不使用 spring。您可以在 camel-parent-2.18.1.pom 中找到所有相关依赖项

<小时/>

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camel和spring相关依赖项的版本。

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