将异常从CXF拦截器传播到异常映射器

将异常从CXF拦截器传播到异常映射器

我一直在研究和测试您的问题。问题是从CXF拦截器抛出的异常逃避了JAX-
RS流（请参阅
CXF团队的答案）

甲

Fault

从拦截器产生可以被获取，实现

handleFault

在拦截器本身

 public void handleFault(Message message) {       Exception e = message.getContent(Exception.class); }

或实施

FaultListener

并在CXF总线上注册

WebClient.getConfig(client).getBus().getProperties().put("org.apache.cxf.logging.FaultListener",new MyFaultListener());public class MyFaultListener implements FaultListener{    public boolean faultOccurred(final Exception exception,final String description,final Message message) {        //return false to avoid warning of default CXF logging interceptor        return false;    }}

但是您不能从拦截器返回自定义响应，也不能对客户端响应故障。

我发现实现所需行为的解决方法是将Response替换为可以由您的常规方法调用处理的自定义对象

进入

Interceptor.handleMessage

检查你所需要的条件，并创建一个

Response

自定义状态和实体。之后，停止链条

public class MyInterceptor extends AbstractPhaseInterceptor<Message> {    public MyInterceptor() {        super(Phase.POST_STREAM);    }    @Override    public void handleMessage(Message message) throws Fault {        if (message != null) { //check the condition to raise the error  //build the custom Response replacing service call Response response = Response         .status(Response.Status.BAD_REQUEST)         .entity("custom error")         .build(); message.getExchange().put(Response.class, response); //abort interceptor chain in you want to stop processing or throw a Fault (catched by handleFault) //message.getInterceptorChain().abort(); //throw new Fault (new MyException());        }    public void handleFault(Message messageParam) {    }}

创建JAXRS客户端时，将ResponseExceptionMapper添加为提供者

providers.add(new ResponseExceptionMapper<WebApplicationException>() {    @Override    public WebApplicationException fromResponse(Response r) {        return new WebApplicationException(r);    }});YourService proxy = JAXRSClientFactory.create(url, clazz,providers);Client client = WebClient.client(proxy);WebClient.getConfig(client).getInInterceptors().add(new MyInterceptor());

此后，对的调用

proxy.yourService()

将引发

WebApplicationException

if如果完成拦截器检查。您可以按期望的方式抓住它或将其扔掉

try{    proxy.yourService();}catch (WebApplicationException e){}

希望这可以帮助
