Mule ESB不适用于Cookie [英] Mule ESB does not work with cookie
本文介绍了Mule ESB不适用于Cookie的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
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，而mule esb则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.

一个类似的问题(不是重复的，因为我有不同版本的m子) 执行http:set-cookie时，Tomcat嵌入式MULE中的 NoSuchMethodError
我也读过这篇 https://www.mulesoft.org/jira/browse/MULE-6705
解决方案
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'
I use mule esb 3.7.0.
I have application A which sends an http request to mule esb, which forwards it to application B. The application B sends response back to mule esb, and mule esb sends it back to the application A. Everything works fine.
Then at one day the application B sends http response with a cookie (JSESSIONID, but it does not matter), and the application A throws timeout exceptions. I debugged mule esb and found this.
org.mule.transport.http.transformers.MuleMessageToHttpResponse->
protected HttpResponse createResponse(Object src, String encoding, MuleMessage msg) throws IOException, TransformerException
This method fails. Line 243

}
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,

A similar question (not a duplicate because I have a different version of mule) NoSuchMethodError in Tomcat embedded MULE when executing http:set-cookie
Also I read this https://www.mulesoft.org/jira/browse/MULE-6705
解决方案
It turns out, the problem is with libraries. We use Spring Boot, which has dependencies, and one of them overrides version of coyote.
provided group: 'org.apache.tomcat', name: 'coyote', version: '6.0.44'
With SpringBoot, it uses embedded-tomcat-core.
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-core', version: '8.0.28'
