Question

我有一个奇怪的问题，似乎无法得到它的底部。基本上需要记录发送到Web服务和接收（使用者）的soap XML。我相信正确的方法是使用Apache提供的开箱即用的拦截器。这些工作正常但是我们有一个特殊的情况，一个方法接受大量的参数/对象并返回大量的参数/对象，这显然会创建一个大的soap请求/响应xml。肥皂请求/响应始终正确打印，但是引发了以下错误：

应用程序配置

Spring config：

<jaxws:client id="serviceClient"
              serviceClass="com.services.stubs.ServiceAPI"
              address="${service.url}">
    <jaxws:inInterceptors>
        <ref bean="incomingInterceptor"/>
    </jaxws:inInterceptors>
    <jaxws:outInterceptors>
        <ref bean="outgoingInterceptor"/>
    </jaxws:outInterceptors>
</jaxws:client>

我的拦截器类：

public class OutLoggingInterceptor extends LoggingOutInterceptor
{
    public OutLoggingInterceptor()
    {
        super(Phase.PRE_STREAM);
    }
}


public class InLoggingInterceptor extends LoggingInInterceptor
{
    public InLoggingInterceptor()
    {
        super(Phase.RECEIVE);
    }
}

抛出错误：

我可以提出几种解决方案。如果他们中的任何一个为您工作，请告知。

1）你为什么要从LoggingOutInterceptor中继承子类呢？如果只需要指定添加它的阶段，只需在Spring上下文配置中使用适当的构造函数。

2）当我使用Apache CXF实现SOAP服务时，我遇到了类似的错误。 A在拦截链中有2个自定义拦截器。其中一个是读取消息的输入流来解析它以执行一些自定义操作。问题是Xerces在解析后关闭了输入流，因此其他拦截器正在获取已经关闭的输入流。

对我有用的唯一解决方案是使用this解决方案复制输入流。

类似的东西：

// Exception handling ommitted

InputStream originalStream = soapMessage.getContent(InputStream.class);

// Reading contents of original stream into memory
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len;
while ((len = originalStream.read(buffer)) > -1) {
    baos.write(buffer, 0, len);
}
baos.flush();
baos.close();

// Open new InputStreams using the recorded bytes
InputStream streamForThisInterceptor = new ByteArrayInputStream(baos.toByteArray());
InputStream streamForOtherInterceptors = new ByteArrayInputStream(baos.toByteArray());

// Replacing stream for other interceptors
soapMessage.setContent(InputStream.class, streamForOtherInterceptors);

糟糕的解决方案，但它是唯一有效的解决方案。

3）你也可以尝试使用Apache commons-io中的CloseShieldInputStream，也许你会有更好的运气。
