无法转换为类型spring.oxm.marshaller:找不到匹配的编辑器或转换策略

Question

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.

Caused by: java.lang.IllegalStateException: Cannot convert value of type [java.lang.String] to required type [org.springframework.oxm.Marshaller] for property 'marshaller': no matching editors or conversion strategy found

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.

                <groupId>org.codehaus.mojo</groupId>

                    </execution>
                </executions>
            </plugin>

我的pom还有这些依赖:

这是我的appContext.xml

          <property name="contextPath" value="com.package.request:com.package.request" />
          </bean>
</beans>

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,它甚至没有到达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,我已经完成了相同的设置,但在我的项目中,它抛出了异常no matching editors or conversion strategy found

我假设你的错误是指这个

<property name="marshaller" value="marshaller" />

属性marshaller指org.springframework.oxm.Marshaller的是类的类型的字段org.springframework.ws.client.core.WebServiceTemplate.你不能给它一个String值"marshaller".

您想要在id的上下文中引用另一个bean marshaller.

<property name="marshaller" ref="marshaller" />

同样的事情unmarshaller.
