我的Tomcat服务器总是抛出以下错误(在Linux中,Tomcat版本是8.5.4,使用tail-fcatalina.out):
第一个错误:

第二个错误:

第三个错误:

前端html总是打印错误:

Failed to load resource: the server responded with a status of 502 (Bad Gateway)

后端服务器主要使用Spring、Jersey,前端使用H5、AngularJS。任何想法,我会欣赏!

这是tomcat在8.5.x以后的重构中引入的一个bug。您可以搜索Tomcat错误列表https://bz.apache.org/bugzilla/show_bug.cgi?id=60918
您可以通过升级tomcat版本或修改server.xml设置useSendfile=“false”来解决该问题。

<Connector executor="tomcatThreadPool" port="8080" protocol="HTTP/1.1" maxHttpHeaderSize="16384" maxThreads="2000" connectionTimeout="60000" disableUploadTimeout="true" redirectPort="8443" useSendfile="false"/>

我不是这方面的Maven,但它似乎是请求或cookie编码的某种问题。也可能是雄猫臭虫。
对于第一个错误,您可以尝试Rfc6265CookieProcessor.请检查this以了解详细信息。

<Context>
....
    <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor" />
....
</Context>

这种类型的错误发生在Tomcat版本的某些问题时。如果没有一个测试用例来重现问题,Tomcat开发人员几乎无能为力。看起来像是多个线程同时作用于同一个套接字。我不知道这是故意的,是Tomcat bug的结果还是框架/应用程序正在做的事情。
我没有太多的知识,但我已经解决了我的问题after ready this.
其他解决方案:-
这也是asked before here。有可能你用的是哪个版本的tomcat?
对于这个例外

SEVERE: An exception or error occurred in the container during the request processing
java.lang.NullPointerException

你需要read this stack overflow answer.
502 Bad Gateway错误是一个HTTP状态代码,表示Internet上的一台服务器收到了来自另一台服务器的无效响应。为此,您需要read this tutorial.
