Question

我尝试使用Apache CXF的BeanValidation功能。现在卡住了因为没有任何线索如何处理和解析验证器抛出的异常。我有网络服务界面：

@WebService
@SOAPBinding(style=SOAPBinding.Style.DOCUMENT, use=SOAPBinding.Use.LITERAL, parameterStyle=SOAPBinding.ParameterStyle.BARE)
public interface TestWSInterface {
    @WebMethod
    @WebResult(name = "helloResponse")
    @Valid
    public Hello.Response hello(@WebParam(name = "helloRequest") @Valid Hello.Request request) throws TestWSException;
}

Hello.Request注释：

@XmlType(name = "HelloRequest")
public static class Request extends Command.Request {

    @NotNull(message = "not null required")
    @Size(min = 1, max = 5, message = "[1..5] characters")
    public String name;
}

在cfx-servlet.xml中进行以下配置：

<jaxws:endpoint id="testWS" implementor="#test" address="/TestWS">
    <jaxws:features>
        <ref bean="commonValidationFeature"/>
    </jaxws:features>
</jaxws:endpoint>
<bean id="commonValidationFeature" class="org.apache.cxf.validation.BeanValidationFeature"/>

所以，然后我用SoapUI运行我的请求并传递包含例如6个字符的名字，我有以下回复：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body>
        <soap:Fault>
            <faultcode>soap:Server</faultcode>
            <faultstring>Fault occurred while processing.</faultstring>
        </soap:Fault>
    </soap:Body>
</soap:Envelope>

所以我的主要问题是 - 如何捕获ConstraintViolationException并使用注释约束中的详细消息扩展生成的错误响应？来自Apache CXF - Bean Validation Feature的文档对我来说看起来不是很有帮助。所以我真的需要这样的例子。

我遇到了同样的问题，我使用AbstractSoapInterceptor修复了它。要注册自定义拦截器，您必须将以下注释添加到Web服务中。

@OutFaultInterceptors(interceptors = { "com.saqi.config.FaultInterceptor" })

之后，您必须按如下方式编写自定义FaultInterceptor。

public class FaultInterceptor extends AbstractSoapInterceptor {

    public FaultInterceptor() {
        super(Phase.MARSHAL);
    }

    @Override
    public void handleMessage(SoapMessage soapMessage) throws Fault {
        Fault fault = (Fault) soapMessage.getContent(Exception.class);

        if (fault.getCause() != null && fault.getCause() instanceof ConstraintViolationException) {

            ConstraintViolationException constraintViolationException = (ConstraintViolationException) fault.getCause();

            if (!constraintViolationException.getConstraintViolations().isEmpty()) {
                Set<ConstraintViolation<?>> constraintViolations = constraintViolationException
                        .getConstraintViolations();

                for (ConstraintViolation constraintViolation : constraintViolations) {
                    fault.setMessage(constraintViolation.getMessage());
                }
            }
        }
    }
}

这将显示您的ConstraintViolationException消息，如下所示。

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>Id should follow the pattern!</faultstring>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

注意：我使用的是cxf 3.1.6版本
