使用拦截器记录 REST 服务但无法记录请求和响应

Question

我有一些 REST 服务，我想记录请求并且 response.They 收到一个 JSON 请求并生成另一个 JSON 响应。我创建了一个拦截器，但无法获取 request/response 正文。这是我的 cxf 配置：

<bean id="ContextInInterceptor" class="main.interceptors.ContextMessageInInterceptor"></bean>
<bean id="ContextOutInterceptor" class="main.interceptors.ContextMessageOutInterceptor"></bean>
<bean id="ContextJSONInInterceptor" class="main.interceptors.ContextJSONInInterceptor"></bean>
<bean id="ContextJSONOutInterceptor" class="main.interceptors.ContextJSONOutInterceptor"></bean>

<cxf:bus>
   <cxf:features>
      <cxf:logging/>
   </cxf:features>

   <cxf:inInterceptors>
      <ref bean="ContextInInterceptor"/>
   </cxf:inInterceptors>
   <cxf:outInterceptors>
      <ref bean="ContextOutInterceptor"/>
   </cxf:outInterceptors>
</cxf:bus>

这是我的拦截器代码：

public class ContextMessageInInterceptor extends AbstractPhaseInterceptor<org.apache.cxf.message.Message> {

       @Autowired
       ContextJSONInInterceptor contextJSONInInterceptor;

       public ContextMessageInInterceptor() {
           super(Phase.PRE_INVOKE);
       }

       @Override
       public void handleMessage(Message message) {
           contextJSONInInterceptor.handleMessage(message);
       }
}

public class ContextJSONInInterceptor extends AbstractPhaseInterceptor<Message> {

    public ContextJSONInInterceptor() {
        super(Phase.PRE_INVOKE);
    }

    @Override
    public void handleMessage(Message message) throws Fault {
        System.out.println("Content-Type: " + message.get(Message.CONTENT_TYPE));
        System.out.println(message.toString());
        System.out.println("---------------");
    }
}

public class ContextMessageOutInterceptor extends AbstractPhaseInterceptor<Message> {

    @Autowired
    ContextJSONOutInterceptor contextJSONOutInterceptor;

    public ContextMessageOutInterceptor() {
        super(Phase.WRITE);
    }

    @Override
    public void handleMessage(Message message) throws Fault {
        contextJSONOutInterceptor.handleMessage(message);
    }
}

public class ContextJSONOutInterceptor extends AbstractPhaseInterceptor<Message> {

    public ContextJSONOutInterceptor() {
        super(Phase.WRITE);
    }

    @Override
    public void handleMessage(Message message) throws Fault {
        System.out.println("Content-Type: " + Message.CONTENT_TYPE);
        System.out.println(message.toString());
        System.out.println("---------------");
    }

}

ContextMessageInInterceptor 和 ContextMessageOutInterceptor 工作正常，它们分别转到 ContextJSONInInterceptor 和 ContextJSONOutInterceptor，但我不知道如何从这些拦截器中获取 request/reponse 正文.我尝试使用 "Message" 常量，我只得到内容类型。

有人知道如何从那些拦截器中获取 request/reponse 主体吗？

非常感谢您的宝贵时间。

Answer 1

AOP 比拦截器更好。您可以将它应用于您的控制器方法，其中 request/response 流量 passes.And 用于在该请求范围内获取请求对象，您可以执行以下操作：

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
            .getRequest();

Answer 2

您有两个选择：使用 HandlerInterceptor 您可以看到请求和方法，通过一些反思您可以获得一些信息，这可能是您需要的一切。

public class ApiInterceptor implements HandlerInterceptor {

@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
    // code
}

@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
//code
}

@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
   // code
    }
}

第二个选项是Spring AOP (which could be complementary). You could use a pointcut that would target all the @RequestMapping() annotations, and an advice that would be executed in the exact moment you want to. I 不久前关于这个的。
