我使用了一个骆驼示例作为用例：
https://svn.apache.org/repos/asf/camel/trunk/examples/camel-example-spring-ws/
假设我们想为这个项目创建一个单元测试：
package org.apache.camel.example.server;
import org.apache.camel.test.spring.CamelSpringTestSupport;
import org.junit.Test;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class IncrementRouteTest extends CamelSpringTestSupport {
@Override
protected AbstractApplicationContext createApplicationContext() {
return new FileSystemXmlApplicationContext(new String[]{
"/src/main/webapp/WEB-INF/spring-ws-servlet.xml"});
}
@Test
public void testSendMatchingMessage() throws Exception {
template.sendBodyAndHeader("spring-ws:rootqname:{http://camel.apache.org/example/increment}incrementRequest?endpointMapping=#endpointMapping",
"<msg>asd</msg>",
"head1",
"headVal1");
}
}
为了简化，我跳过额外的端点创建模拟它并验证结果是否满足..
在代码上运行将导致：

经过一些调试后，我得到了更多信息..第89行 body = getEndpoint（）。getConfiguration（）。getWebServiceTemplate（）。sendSourceAndReceive（sourcePayload，callback，SOURCE_EXTRACTOR）;
getWebServiceTemplate（）导致nullpointer ...
使用时效果很好：
package org.apache.camel.example.server;
import org.apache.camel.builder.RouteBuilder;
public class FileRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
from("file://target/inbox")
.to("file://target/outbox");
}
}
和内部测试：
package org.apache.camel.example.server;
import org.apache.camel.EndpointInject;
import org.apache.camel.component.mock.MockEndpoint;
import org.apache.camel.test.spring.CamelSpringTestSupport;
import org.junit.Test;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class IncrementRouteTest extends CamelSpringTestSupport {
@Override
protected AbstractApplicationContext createApplicationContext() {
return new FileSystemXmlApplicationContext(new String[]{
"/src/main/webapp/WEB-INF/spring-ws-servlet.xml"});
}
@EndpointInject(uri = "mock:file:target/outbox/hello.txt")
protected MockEndpoint resultEndpoint;
@Test
public void testSendMatchingMessage() throws Exception {
template.sendBodyAndHeader("file://target/inbox",
"Hello World", "asd", "hello.txt");
resultEndpoint.assertIsSatisfied();
}
}
在SpringWebserviceProducer.java:89中可能是由NullPointer引起的 如何测试弹簧路线？
