由於公司要求，在Tomcat

Question

中使用Moxy，因此我們無法使用Glassfish作爲應用服務器。不過我想用Moxy。所以我試圖讓新的Metro版本（https://blogs.oracle.com/mgrebac/entry/metro_2_2_jaxb_2）與tomcat 7一起工作。我使用Spring來管理它，以引導Moxy，就像它在地鐵文檔（http://metro.java.net/guide/user-guide.html#springa）中所描述的那樣，但我沒有管理它以使它達到與Moxy合作。

我已經嘗試了地鐵文檔（http://metro.java.net/2.2/guide/ch17.html）中提到的解決方案和此處提到的解決方案（Use Moxy as default JAXB Implementation）。

但我可以把它弄出來的最多的是以下情況除外：

我的測試web服務是：

@WebService 
public class TestService { 
    public String sayHello() throws JAXBException { 
     System.out.println(org.eclipse.persistence.Version.getVersion()); 
     JAXBContext c = JAXBContext.newInstance(TestPojo.class); 
     return "Hello"; 
    } 
} 

而且是在該MOXY罐子（org.eclipse.persistence。 moxy-2.4.0.jar，org.eclipse.persistence.core-2.4.0.jar，org.eclipse.persistence.asm-3.3.1.v201206041142.jar）位於類路徑中。

THX的幫助

您可以隨時使用JAX-WS Provider機制，以充分利用EclipseLink JAXB (MOXy)：

Web服務例子

import javax.xml.bind.*; 
import javax.xml.bind.util.JAXBSource; 
import javax.xml.transform.Source; 
import javax.xml.ws.*; 

@ServiceMode(Service.Mode.PAYLOAD) 
@WebServiceProvider(
    portName = "FindCustomerPort", 
    serviceName = "FindCustomerService", 
    targetNamespace = "http://service.jaxws.blog/", 
    wsdlLocation = "WEB-INF/wsdl/FindCustomerService.wsdl") 
public class FindCustomerService implements Provider<Source> { 

    private JAXBContext jaxbContext; 

    public FindCustomerService() { 
     try { 
      jaxbContext = JAXBContext.newInstance(FindCustomerResponse.class, 
        FindCustomerRequest.class); 
     } catch (JAXBException e) { 
      throw new WebServiceException(e); 
     } 
    } 

    @Override 
    public Source invoke(Source request) throws WebServiceException { 
     try { 
      Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); 
      FindCustomerRequest fcRequest = (FindCustomerRequest) unmarshaller 
        .unmarshal(request); 

      Customer customer = new Customer(); 
      customer.setId(fcRequest.getArg0()); 
      customer.setFirstName("Jane"); 
      customer.setLastName("Doe"); 

      FindCustomerResponse response = new FindCustomerResponse(); 
      response.setValue(customer); 

      return new JAXBSource(jaxbContext, response); 
     } catch (JAXBException e) { 
      throw new WebServiceException(e); 
     } 
    } 

}
