如何使用JAX-WS webfault

Question

我写了一个webservice并试图抛出我的自定义异常,但我收到错误请帮我解决.

import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService(name = "WebService")
public class WebServiceTest {
    public String sayHello(String name) throws InvalidInputException {
        throw new InvalidInputException("I am testing", null);
    }
    public static void main(String[] args) {
        WebServiceTest server = new WebServiceTest();
        Endpoint endpoint = Endpoint.publish(
                "http://localhost:9191/webServiceTest", server);
    }
}


import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlType;

@XmlType(name = "InputMessageValidationFaultType")
public class FaultBean {

    @XmlAttribute
    protected String msg;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String value) {
        this.msg = value;
    }

}


import javax.xml.ws.WebFault;

@WebFault(faultBean = "mytest.com.inc.FaultBean")
public class InvalidInputException extends Exception {

    private static final long serialVersionUID = 1L;

    private FaultBean faultBean;

    public InvalidInputException() {
        super();
    }

    public InvalidInputException(String message, FaultBean faultBean,
            Throwable cause) {
        super(message, cause);
        this.faultBean = faultBean;
    }

    public InvalidInputException(String message, FaultBean faultBean) {
        super(message);
        this.faultBean = faultBean;
    }

    public FaultBean getFaultInfo() {
        return faultBean;
    }
}

错误消息 线程"main"中的异常java.lang.NoSuchMethodError:javax.xml.ws.WebFault.messageName()Ljava/lang/String; at com.sun.xml.ws.model.RuntimeModeler.processExceptions(RuntimeModeler.java:1162)at com.sun.xml.ws.model.RuntimeModeler.processDocWrappedMethod(RuntimeModeler.java:898)at com.sun.xml.ws .model.RuntimeModeler.processMethod(RuntimeModeler.java:666)位于com.sun.xml.ws.model.RuntimeModeler.processClass(RuntimeModeler.java:420)的com.sun.xml.ws.model.RuntimeModeler.buildRuntimeModel(RuntimeModeler) .java:254)com.sun.xml.ws.server.EndpointFactory.createSEIModel(EndpointFactory.java:338)at com.sun.xml.ws.server.EndpointFactory.createEndpoint(EndpointFactory.java:201)at com. sun.com.ws.api.server.WSEndpoint.create(WSEndpoint.java:505)位于com.sun的com.sun.xml.ws.transport.http.server.EndpointImpl.createEndpoint(EndpointImpl.java:257). xml.ws.transport.http.server.EndpointImpl.publish(EndpointImpl.java:181)位于javax.xml.ws.Endpoint的com.sun.xml.ws.spi.ProviderImpl.createAndPublishEndpoint(ProviderImpl.java:123).在mytest.com.inc.WebServiceTest.main上发布(Endpoint.java:170)(WebServiceTe st.java:13)

Answer 1

上次我看到这个错误,它是由于使用的JAX-WS版本(2.1.x和2.2.x)的错配,你可能正在编译2.1.x版本但是运行2.2.x,或者其他方式回合.

请记住,JDK 6包含2.1.x版本的JAX-WS,因此您可能必须使用支持的库机制来强制使用2.2.x.

老问题我知道,但我认为你的FaultBean类中的方法名称需要是getMessage和setMessage(而不是getMsg和setMsg) - 请参阅这篇优秀的文章:
