Apache CXF :- 我如何使用 cxf 拦截器提取有效负载数据

Question

我应该遵循哪些步骤来使用 Apache CXF 拦截器提取有效载荷？

Answer 1

您的拦截器需要从 AbstractPhaseInterceptor 或子类

扩展

public class MyInterceptor extends AbstractPhaseInterceptor<Message> {
    public MyInterceptor () {
        super(Phase.RECEIVE);
    }

    public void handleMessage(Message message) {
        //Get the message body into payload[] and set a new non-consumed  inputStream into Message
        InputStream in = message.getContent(InputStream.class);
        byte payload[] = IOUtils.readBytesFromStream(in);
        ByteArrayInputStream bin = new ByteArrayInputStream(payload);
        message.setContent(InputStream.class, bin);
    }

    public void handleFault(Message messageParam) {
        //Invoked when interceptor fails
    }
}

以编程方式添加拦截器

MyInterceptor myInterceptor = new MyInterceptor();

Server server = serverFactoryBean.create();
server.getEndpoint().getInInterceptor().add(myInterceptor);

或使用配置

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:cxf="http://cxf.apache.org/core"
       xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd">

    <bean id="MyInterceptor" class="demo.interceptor.MyInterceptor"/>

    <!-- We are adding the interceptors to the bus as we will have only one endpoint/service/bus. -->

    <cxf:bus>
        <cxf:inInterceptors>
            <ref bean="MyInterceptor"/>
        </cxf:inInterceptors>
        <cxf:outInterceptors>
            <ref bean="MyInterceptor"/>
       </cxf:outInterceptors>
    </cxf:bus>
</beans>

您可以使用 LoggingInInterceptor 以字符串形式检索负载

public class CustomInInterceptor extends LoggingInInterceptor {

    /**
     * SLF4J Log Instance
     */
    private final static Logger LOG = LoggerFactory.getLogger(CustomInInterceptor.class);

    /**
     * formats logging message and also attaches input xml to thread context
     * 
     * @see org.apache.cxf.interceptor.LoggingInInterceptor#formatLoggingMessage(org.apache.cxf.interceptor.LoggingMessage)
     */
    @Override
    protected String formatLoggingMessage(final LoggingMessage loggingMessage) {
  //The below line reads payload and puts into threads context, which I use later to save in db 
    KpContextHolder.setInputXml(loggingMessage.getPayload().toString());
        return super.formatLoggingMessage(loggingMessage);
    }

}
