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>
当我运行该项目时，出现以下错误。如果我删除该依赖项，它会起作用。我已经在两个不同的项目上尝试过这个，结果也是一样。还有什么必须添加到 pom 中才能使 jsonpath 工作？好像是在提示ASM？

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。 Camel 组件应该获得所有依赖的 jar 。
最佳答案
我在 Camel nabble 论坛上发布了这个，确实似乎您需要添加 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>
关于apache-camel - 添加到 pom 文件后，组件camel-jsonpath 出现错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35176594/
