组件camel-jsonpath在添加到pom文件后出现错误
提问于 2016-02-03 12:05:20
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>当我运行这个项目时，我得到下面的错误。如果我移除这个依赖项，它就能正常工作。我已经在两个不同的项目上尝试过了，同样的情况也发生了。要让jsonpath正常工作，还需要向pom添加任何其他内容吗？它似乎在抱怨ASM？

<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm-commons</artifactId>
<version>5.0.3</version>
<scope>runtime</scope>
</dependency> 它起作用了，但怀疑这是正确的方式。camel-component应该获得所有依赖的jars。

我在Camel nabble论坛上发布了这篇文章，实际上，您似乎需要添加asm依赖项才能使其工作。
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> Stack Overflow用户

pom.xml是关于编译时依赖项。您有一个关于缺少依赖项(org.objectweb.asm)的运行时错误。您应该将其添加到您的容器中。
在堆栈中跟踪:在蓝图上下文中注册新服务。然后，该服务被注入到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，而要创建这种代理，白羊座蓝图需要org.objectweb.asm。我不认为这个错误与camel-jsonpath有直接关系。

在我的例子中，当使用5.0.3版本的asm-commons时，我仍然收到一些错误。作为前面答案的另一种选择，可以使用asm-all工件，因为它包含了在我的场景中以其他方式破坏的其他依赖项。
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm-all</artifactId>
<scope>runtime</scope>
</dependency>然而，关于部署，使用这种依赖关系将项目集成到Fabric8似乎是不可能的(控制台日志上没有错误，容器不会启动)，所以不确定是否有更好的替代方案，具有某种驼峰-jsonpath特性。
希望这能帮助到别人。
