Error: no matching editors or conversion strategy found for XML to object conversion and vice vera

Question

我正在尝试使用 marsheller 将 xml 转换为对象并将对象转换为 xml。但是我收到以下错误。

错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'XMLConverter' defined in class path resource [applicationContext.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'org.springframework.oxm.castor.CastorMarshaller' to required type 'javax.xml.bind.Marshaller' for property 'marshaller'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.springframework.oxm.castor.CastorMarshaller] to required type [javax.xml.bind.Marshaller] for property 'marshaller': no matching editors or conversion strategy found

代码片段：

App.java

 ApplicationContext appContext = new ClassPathXmlApplicationContext("App.xml");
            XMLConverter converter = (XMLConverter) appContext.getBean("XMLConverter");
Message message = new Message();
        List<HeaderPojo> headerList = new ArrayList<HeaderPojo>();
        List<InputInfoPojo> inputInfoList = new ArrayList<InputInfoPojo>();
        List<MessageBody> MessageBody = new ArrayList<MessageBody>();

        HeaderPojo Header = new HeaderPojo();

        Header.setMessageName("Hello");
        Header.setMessageDesc("hi");
        Header.setMessageType("Request");

        InputInfoPojo InputInfo = new InputInfoPojo();

        InputInfo.setProviderID("1234");
        InputInfo.setProviderLocation("1");
        InputInfo.setProviderRequestSource("sff");

        headerList.add(Header);
        inputInfoList.add(InputInfo);

        MessageBody Body = new MessageBody();
        Body.setInputInfo(inputInfoList);

        MessageBody.add(Body);

        message.setHeader(headerList);
        message.setBody(MessageBody);


            try {
                System.out.println("------- Object to XML -----------\n");
                JAXBContext jaxbContext = JAXBContext.newInstance(Message.class);
                Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

                // output pretty printed
                jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

                jaxbMarshaller.marshal(message, System.out);

                System.out.println("\n------- XML to Object -----------\n");

                String xml = "<message><body><inputInfo><providerID>1234</providerID><Location>1</Location><providerRequestSource>sff</providerRequestSource></inputInfo></body><header><messageDesc>hello</messageDesc><messageName>FeeSchedules</messageName><messageType>Request</messageType></header></message>";
                StringReader reader = new StringReader(xml);
                Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
                Message elementsOut = (Message) jaxbUnmarshaller.unmarshal(reader);
                System.out.println(elementsOut);

            } catch (JAXBException e) {
                e.printStackTrace();
            }    
        }

我重新启动了服务器，它开始工作了。 :) 如果将来有人想参考，此代码可以正常工作。
