我长期以来一直在努力解决这个错误，谷歌搜索，看看网络上的例子，仍然没有开始工作。说实话，我不明白为什么我的项目会抛出这个错误。

所以我的设置是Spring Web Services，Jaxb2，maven。我已经预定义了xsd文件，并通过jaxb2 maven插件从它们生成了java类。
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>jaxb2-maven-plugin</artifactId>
<executions>
<execution>
<id>schema1-xjc</id>

<schemaDirectory>src/main/resources/</schemaDirectory>
<schemaFiles>ApplicationResponse.xsd</schemaFiles>
<packageName>com.package.response</packageName>
</configuration>
</execution>
</executions>
</plugin>
我的pom还有这些依赖项：

这是我的appContext.xml

我的服务客户端类
@Component
public class NorServiceClient implements NorService {
@Autowired
private WebServiceTemplate wsTemplate;
public void setDefaultUri(String defaultUri) {
wsTemplate.setDefaultUri(defaultUri);
}
public ApplicationResponse downloadFileList(ApplicationRequest request) {
// Command: DownloadFileList
return (ApplicationResponse) wsTemplate.marshalSendAndReceive(request);
}
}
我的测试用例：
public class AppTest extends TestCase {
private ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("/appContext.xml");
@Test
public void testApplicationRequest() {
assertNotNull(new Object());
System.out.println("Context: " + context);
NorService norService = (NorService) context.getBean("norServiceClient");
ApplicationRequest request = new ApplicationRequest();
nordeaService.downloadFileList(request);
}
}
启动我的应用程序时，它甚至没有访问service.downloadFileList，它在初始化上下文时抛出异常。所以我不认为这可能是我已经实例化空ApplicationRequest对象的问题。
问题出在哪里？通过互联网上的所有示例，我已经以相同的方式完成了设置，但在我的项目中，它抛出了no matching editors or conversion strategy found
答案 0 :(得分：6)
我认为你的错误是指
<property name="marshaller" value="marshaller" />
属性marshaller指的是类org.springframework.oxm.Marshaller的{{1}}类型的字段。你不能给它一个org.springframework.ws.client.core.WebServiceTemplate的字符串值。
您想在ID为"marshaller"的上下文中引用另一个bean。
marshaller <property name="marshaller" ref="marshaller" />
也是如此。
