组件camel-jsonpath在添加到pom文件后出错

时间：2016-02-03 12:05:20

标签： apache-camel osgi

在一个干净的Camel项目中，我添加了以下依赖项：

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-jsonpath</artifactId>
  <version>2.16.1</version>       
</dependency>

当我运行项目时，我得到以下错误。如果我删除该依赖项，它的工作原理我在两个不同的项目上尝试了这个，同样的事情发生了。还有什么必须添加到pom中才能使用jsonpath吗？它似乎抱怨ASM？

编辑： 添加后：

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-commons</artifactId>
    <version>5.0.3</version>
    <scope>runtime</scope>
</dependency>

它有效，但怀疑这是正确的方法。驼峰组件应该获得所有依赖的罐子。

答案 0 :(得分：3)

我在Camel nabble论坛上发布了这个，事实上你似乎需要添加asm依赖来让它工作。

http://camel.465427.n5.nabble.com/Error-with-Camel-component-camel-jsonpath-td5777201.html 

<dependency>
    <groupId>org.ow2.asm</groupId>
    <artifactId>asm-commons</artifactId>
    <version>5.0.3</version>
    <scope>runtime</scope>
</dependency>

答案 1 :(得分：0)

在我的情况下，当使用版本5.0.3的asm-commons时，我仍然收到一些错误。作为对先前答案的替代，可以使用asm-all工件，因为它包含在我的方案中打破其他依赖性的其他依赖项。

<dependency>
  <groupId>org.ow2.asm</groupId>
  <artifactId>asm-all</artifactId>
  <scope>runtime</scope>
</dependency>

但是，关于部署，似乎很难将使用此依赖项的项目集成到Fabric8（控制台日志和容器上没有错误无法启动），因此不确定是否有更好的替代方案，使用某种类型的camel-jsonpath特征

希望它有所帮助。

答案 2 :(得分：-1)

pom.xml是关于编译时依赖性的。您有关于缺少依赖项的运行时错误（org.objectweb.asm）。您应该将它添加到容器中。

在堆栈跟踪中：在蓝图上下文中注册了新服务。然后将此服务注入另一个蓝图上下文中。对于这个服务，蓝图容器想要将它包装在一个新的代理中，并且为了创建这种代理，aries蓝图需要org.objectweb.asm。我不认为这个错误与camel-jsonpath直接相关。
