Question

我使用的是ule esb 3.7.0。

我有一个应用程序A，它将HTTP请求发送到mule esb，然后将其转发到应用程序B。应用程序B将响应发送回给mule esb，然后mule esb将其发送回应用程序A。一切正常。

然后，有一天，应用程序B发送带有cookie的http响应（JSESSIONID，但没有关系），并且应用程序A抛出超时异常。我调试了ule esb并找到了它。

org.mule.transport.http.transformers.MuleMessageToHttpResponse->
    protected HttpResponse createResponse(Object src, String encoding, MuleMessage msg) throws IOException, TransformerException

此方法失败。第243行

    for (String headerName : headerNames) {
        if (HttpConstants.HEADER_COOKIE_SET.equals(headerName))
        {
            // TODO This have to be improved. We shouldn't have to look in all
            // scopes
            Object cookiesObject = msg.getInvocationProperty(headerName);
            if (cookiesObject == null)
            {
                cookiesObject = msg.getOutboundProperty(headerName);
            }
            if (cookiesObject == null)
            {
                cookiesObject = msg.getInboundProperty(headerName);
            }
            if (cookiesObject == null)
            {
                continue;
            }

            if (!(cookiesObject instanceof Cookie[]))
            {
                response.addHeader(new Header(headerName, cookiesObject.toString()));
            }
            else
            {
                Cookie[] arrayOfCookies = CookieHelper.asArrayOfCookies(cookiesObject);
                for (Cookie cookie : arrayOfCookies)
                {
                    /////////// THIS ONE FAILS
                    response.addHeader(new Header(headerName,
                        CookieHelper.formatCookieForASetCookieHeader(cookie)));
                }
            }
        }
        else
        {
            Object value = msg.getOutboundProperty(headerName);
            if (value == null)
            {
                value = msg.getInvocationProperty(headerName);
            }
            if (value != null)
            {
                response.setHeader(new Header(headerName, value.toString()));
            }
        }
   }

org.mule.transport.http.CookieHelper包含编译错误。

我也读过这篇 https://www.mulesoft.org/jira/browse/MULE-6705

Answer 1

事实证明，问题出在库中。我们使用的是Spring Boot，它具有依赖性，其中之一会覆盖土狼的版本。

provided group: 'org.apache.tomcat', name: 'coyote', version: '6.0.44'

使用SpringBoot，它使用Embedded-tomcat-core。

compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.0.28'

Mule ESB不适用于Cookie
