将参数传递给 Spring 肥皂拦截器 [英] Pass parameter to Spring soap interceptor

问题描述

我有进行 Web 服务调用的 Spring 集成出站网关.我有一个拦截器拦截soap请求并记录到日志文件.现在我想将一个参数传递给拦截器类的 handleRequest 方法，以便我可以将每个记录的soap请求关联到数据库中的一个id.

I have spring integration outbound gateway that makes web service call. I have a interceptor that intercepts soap request and logs to log file. Now I want to pass a parameter to handleRequest method of interceptor class so that I can associate each logged soap request to an id in database.

我需要传递给拦截器的值 id 存储在名称为 id 的标头中代码如下所示.

The value id I need to pass to interceptor is stored in headers with name id code looks something like below.

<int-ws:outbound-gateway  uri="${soap.url} interceptor="interceptor"  >
</int-ws:outbound-gateway>

下面是拦截器.

public class Interceptor implements ClientInterceptor {

@Override
public boolean handleRequest(MessageContext messageContext) throws WebServiceClientException {

//id below is parameter that needs to be passed.

    LOGGER.info("soap request for "+id +" is " +messageContext.getRequest().getDocument().toString());

    return true;
}

}

我想过在 bean 定义中为 Interface 设置一个属性.

I thought of setting a property to Interface in the bean definition.

<bean id="interceptor" class="com.services.Interceptor" >
    <property name="id" value="#{headers['id']}" />
</bean>

但这不起作用，因为我无法以某种方式访问​​标题.在服务器启动期间出现异常.. 即使我解决了这个异常，这也会有问题，因为对象是单例.这里还有其他指针吗?

But this is not working as I am unable to access headers here somehow. getting exception during server start up .. Even if I get this exception resolved, this will have issues as object is singleton.Any other pointers here ?

ngframework.beans.factory.config.BeanExpressionContext' - maybe not public?

推荐答案

查看我对 你的另一个问题为什么你不能做你正在尝试的事情.

See my answer to your other question for why you can't do what you are trying.

要将参数传递给拦截器，您可以使用 ThreadLocal - 在网关上游添加服务以设置您的值，然后在拦截器中检索/删除它.

To pass an argument to your interceptor, you could use a ThreadLocal - add a service upstream of the gateway to set your value and then retrieve/remove it in the interceptor.
