为什么在运行基于spring的camel junit测试用例时出现java.lang.NoSuchMethodError

我必须使用JUnit测试我的route builder，我得到java.lang.NoSuchMethodError，我是否缺少任何配置，或者我访问route builder的方式是否应该更改。请在此处找到RouteBuilder、上下文和Junit类

@Component
public class MyRouteBuilder extends SpringRouteBuilder {

@Autowired
private SourcePoint sourcePoint;

@Autowired
private DestinationPoint    destinationPoint;

@Override
public void configure() throws Exception {

    from(sourcePoint.getString()).to(destinationPoint.getString());
}

我在适当的maven位置创建了JUnit测试用例及其上下文，如下所示

src/test/java/org/apache/camel/spring/patterns/MyRouteBuilderTest.java
src/test/resources/org/apache/camel/spring/patterns/MyRouteBuilderTest-context.xml

在这里，我附上了两个文件

***** MyRouteBuilderTest-context.xml ***
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="

   http://www.springframework.org/schema/beans/spring-beans.xsd
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context.xsd
   http://camel.apache.org/schema/spring 
   http://camel.apache.org/schema/spring/camel-spring.xsd">

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <routeBuilder ref="MyRouteBuilder" />
</camelContext>

<context:component-scan base-package="com.myroute" />

为了您的验证，我附上日志以及

使用Camel test Spring时，需要将Spring 4.0.x与Camel 2.14.x一起使用，因为它不支持Spring 4.1。Camel2.15中提供了对Spring4.1的支持，现在有两个Spring测试模块

• camel-test-spring40-用于弹簧4.0.x
• 驼峰试验弹簧-用于弹簧4.1及以后

这也在发行说明中被记录，在考虑SECTION/P>的重要变化中。

我怀疑您使用不同版本的camel或spring jar编译和运行。您是如何控制jar依赖关系的？@emeraldjava查找我的spring和apach骆驼版本
