如何在CXF拦截器中获取HTTP RESPONSE CODE？

Question

我有基于Apache CXF的Web服务。我编写了拦截器来记录一些包含http响应代码的特定内容。

public class MyOutInterceptor extends AbstractPhaseInterceptor<Message> { 

    public MyOutInterceptor() { 
     super(Phase.SEND); 
    } 

    @Override 
    public void handleMessage(Message message) throws Fault { 
     Integer responseCode = (Integer) message.get(Message.RESPONSE_CODE); 
     //... 
    } 
} 

但是!!! responseCode是null。即使我改变拦截器阶段，它总是null。

UPD。申请春/ CXF配置：https://gist.github.com/alexiuscrow/b5ceb2df7d652a77cd788454e0792211

UPD。治标不治本

@Override 
public void handleMessage(Message message) throws Fault { 
    Integer responseCode = (Integer) message.get(Message.RESPONSE_CODE); 
    if (null == responseCode) { 
     HttpServletResponseWrapper responseWrapper = 
      (HttpServletResponseWrapper) message.get(AbstractHTTPDestination.HTTP_RESPONSE); 
     responseCode = responseWrapper.getStatus(); 
    } 
    //... 
}

请确保您已注册的拦截器outinterceptor不是outFaultInterceptor or FaultInterceptor等在这里被验证的例子。

import org.apache.cxf.annotations.Provider; 
import org.apache.cxf.annotations.Provider.Type; 
import org.apache.cxf.interceptor.Fault; 
import org.apache.cxf.message.Message; 
import org.apache.cxf.phase.AbstractPhaseInterceptor; 
import org.apache.cxf.phase.Phase; 
import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.stereotype.Component; 

@Component 
@Provider(value=Type.OutInterceptor) 
public class KpOutInterceptor2 extends AbstractPhaseInterceptor<Message> { 

    private final static Logger LOG = LoggerFactory.getLogger(KpOutInterceptor2.class); 

    public KpOutInterceptor2() { 
     super(Phase.SEND); 

    } 

    @Override 
    public void handleMessage(Message message) throws Fault { 
     LOG.info("JAXRS response status code is {}", message.get(Message.RESPONSE_CODE)); 
    } 

} 

或者更好的方式使用JAXRS 2.0标准过滤器。

import java.io.IOException; 

import javax.ws.rs.container.ContainerRequestContext; 
import javax.ws.rs.container.ContainerResponseContext; 
import javax.ws.rs.container.ContainerResponseFilter; 
import javax.ws.rs.ext.Provider; 

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
import org.springframework.stereotype.Component; 

@Component 
@Provider 
public class KpOutInterceptor implements ContainerResponseFilter { 

    private final static Logger LOG = LoggerFactory.getLogger(KpOutInterceptor.class); 

    @Override 
    public void filter(ContainerRequestContext reqCtx, ContainerResponseContext resCtx) throws IOException { 

     LOG.info("JAXRS response status code is {}", resCtx.getStatus()); 

    } 

}
