Question

我从JSF注释迁移到CDI。我将@ManagedBean更改为@Named，并将SessionScoped包从javax.faces.bean更改为javax.enterprise.context。当我开始申请并尝试继续antek.xhtml时，我遇到了以下异常：

Error Rendering View[/html/antek.xhtml] javax.faces.FacesException: Could not retrieve value of component with path : {Component-Path : [Class: org.ajax4jsf.component.AjaxViewRoot,ViewId: /html/antek.xhtml][Class: javax.faces.component.html.HtmlOutputText,Id: pojo]}

当然在迁移之前一切都还可以。我在WebSphere Application Server 8.0.0.7上工作。

我项目的源代码： AntekDto.java

@XmlType // without that the same error is thrown
public class AntekDto implements Serializable {
    private static final long serialVersionUID = 1L;
    private String awesomeFiled;

    public String getAwesomeFiled() {
        return this.awesomeFiled;
    }
    public void setAwesomeFiled(final String awesomeFiled) {
        this.awesomeFiled = awesomeFiled;
    }
}

AntekWebService.java

@WebService(targetNamespace = "http://antek.com/core")
public interface AntekWebService {
    @WebMethod(operationName = "getPojo")
    @RequestWrapper(className = "GetPojoRequestWrapper")
    @ResponseWrapper(className = "GetPojoResponseWrapper")
    AntekDto getPojo();
}

AntekServiceImpl.java

@WebService(endpointInterface = "com.antek.testwebservice.AntekWebService", serviceName = "AntekService", targetNamespace = "http://antek.com/core")
public class AntekServiceImpl implements AntekWebService {
    @Override
    public AntekDto getPojo() {
        final AntekDto antekDto = new AntekDto();
        antekDto.setAwesomeFiled("some text for awesome field");
        return antekDto;
    }
}

AntekBean.java

@Named
@SessionScoped
public class AntekBean implements Serializable {
    private static final long serialVersionUID = 2307667354352709172L;

    @Produces
    @WebServiceRef(name = AntekService.SERVICE_PORT_NAME, value = AntekService.class)
    private transient AntekWebService antekWebService;

    public String getPojo() {
        return "<start>" + this.antekWebService.getPojo().getAwesomeFiled() + "<end>";
    }
}

AntekService.java

@WebServiceClient(name = AntekService.SERVICE_NAME, targetNamespace = AntekService.NAMESPACE, wsdlLocation = AntekService.WSDL_LOCATION)
public class AntekService extends Service {
    public static final String SERVICE_NAME = "AntekService";
    public static final String SERVICE_PORT_NAME = SERVICE_NAME + "Port";
    public static final String NAMESPACE = "http://antek.com/core";
    public static final String WSDL_LOCATION = "http://localhost:" + WebServiceProperties.PORT_NUMBER
            + "/ApplicationClientWS/" + SERVICE_NAME + "/" + SERVICE_NAME + ".wsdl";

    public AntekService(final URL wsdlLocation, final QName serviceName) {
        super(wsdlLocation, serviceName);
    }

    @WebEndpoint(name = AntekService.SERVICE_PORT_NAME)
    public final AntekWebService getAntekServicePort() {
        return super.getPort(new QName(NAMESPACE, SERVICE_PORT_NAME), AntekWebService.class);
    }
}

beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
</beans>

antek.xhtml

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:jsp="http://java.sun.com/JSP/Page"

    </head>
    <body>
        Object: <h:outputText id="pojo" value="#{antekBean.pojo}" />
    </body>
</html>

有人可以解释一下为什么会抛出这个异常吗？

从JSF迁移到CDI - javax.xml.bind.JAXBException：此上下文不知道Class
