在 tomcat 中使用 Moxy 和 Metro

Question

由于公司要求，我们不能将 Glassfish 用作应用程序服务器。尽管如此，我还是想使用 Moxy。所以我试图让新的 Metro 版本 (https://blogs.oracle.com/mgrebac/entry/metro_2_2_jaxb_2) 与 tomcat 7 一起工作。我使用 Spring 管理它以引导 Moxy，就像 Metro 文档 (http://metro.java.net/guide/user-guide.html#springa) 中描述的那样，但我没有管理它让它与 Moxy 一起工作。

我已经尝试过 Metro 文档中提到的解决方案 (http://metro.java.net/2.2/guide/ch17.html) 和这里提到的解决方案 (Use Moxy as default JAXB Implementation)。

但我能从中得到的最多的是以下例外：

我的测试网络服务是：

@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";
    }
}

是的，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）在类路径中。

谢谢帮助

您始终可以使用 JAX-WS Provider 机制来利用 EclipseLink JAXB (MOXy)：

示例网络服务

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);
        }
    }

}
