junit - 为什么我在运行基于 spring 的camel junit 测试用例时收到 java.lang.NoSuchMethodError

Question

我必须使用 JUnit 测试我的路由构建器，但我收到了 java.lang.NoSuchMethodError，我是否缺少任何配置或应该更改访问路由构建器的方式。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());
}

我创建了 JUnit 测试用例，它的上下文位于正确的 Maven 位置，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

这里我附加了两个文件

***** 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://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" />

***** MyRouteBuilderTest.class ***
@RunWith(CamelSpringJUnit4ClassRunner.class)
@BootstrapWith(CamelTest.class)
@ContextConfiguration
@DirtiesContext(classMode = ClassMode.AFTER_EACH_TEST_METHOD)
@MockEndpoints("log:*")
@DisableJmx(false)
public class EmypaRouteBuilderTest extends CamelSpringTestSupport {

private static final Logger logger              = LoggerFactory.getLogger(MyRouteBuilderTest.class);

@Autowired
private MyRouteBuilder  myRouteBuilder  = null;

@Override
protected AbstractApplicationContext createApplicationContext() {

    return new ClassPathXmlApplicationContext("Application-context.xml");
}
@Test
public void testRead throws exception(){
    context.start();
    Thread.sleep(10 * 60 * 1000);
   }
}

为了便于验证，我还附上了日志

Answer 1

使用camel-test-spring时，您需要将Spring 4.0.x与Camel 2.14.x一起使用，因为它不支持Spring 4.1。 Camel 2.15 中将支持 Spring 4.1，其中现在有 2 个 Spring 测试模块

• camel-test-spring40 - 适用于 Spring 4.0.x
• camel-test-spring - 适用于 Spring 4.1 及以上

这也记录在发行说明中的​​需要考虑的重要更改部分
