Java Tomcat 8.5.45在启动后抛出大量NullPointerException-s，但仍能正常工作,java,tomcat,Java,Tomcat,最近，我们将ApacheTomcat服务器从8.5.32更新为8.5.45。我们注意到，Tomcat在启动后会向catalina.out发送NullPointerException-s音，但是，连接器工作正常，它处于打开状态并正在侦听： 10-Oct-2019 10:48:31.210 INFO [main] org.apache.catalina.startup.Catalina.start Server startup in 13452 ms 10-Oct-2019 10:48:31.247

最近，我们将ApacheTomcat服务器从8.5.32更新为8.5.45。我们注意到，Tomcat在启动后会向catalina.out发送NullPointerException-s音，但是，连接器工作正常，它处于打开状态并正在侦听：

我们查过论坛等等。。。找到将

协议更改为org.apache.coyote.http11.Http11NioProtocol的建议，但没有帮助。
连接器的配置如下所示：
<Connector port="8443" minProcessors="5" maxProcessors="75"
      protocol="org.apache.coyote.http11.Http11NioProtocol"
      SSLEnabled="true" server=" "
      enableLookups="false" disableUploadTimeout="true"
      acceptCount="100" debug="0" scheme="https" secure="true"
      keystoreFile="<keystore>"
      keystorePass="<password>"
      truststoreFile="<truststore>"
      truststorePass="<password>"
      URIEncoding="UTF-8"
      clientAuth="true" xpoweredBy="false" 
      connectionTimeout="60000" maxHttpHeaderSize="8192" 
      allowTrace="false"
      sslEnabledProtocols="TLSv1.2"
      SSLHonorCipherOrder="on"
      useServerCipherSuitesOrder="true"
      ciphers="SSL_DHE_DSS_WITH_AES_128_CBC_SHA..."/>

在Ubuntu 20.04上使用Tomcat 8.5进行安装时，我遇到了类似的问题
这是我的连接器：
Connector protocol="org.apache.coyote.http11.Http11Protocol"
          port="8443" maxThreads="200" scheme="https"
          secure="true" SSLEnabled="true"
          keystoreFile="/usr/share/tomcat.keystore"
          keystorePass="GODMYROCK"
          clientAuth="false" sslProtocol="TLS"
          URIEncoding="UTF-8"
          compression="force"
          compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"/>

但每次启动应用程序时，它都会在日志中抛出以下错误：
严重[https-jsse-nio-8443-exec-3]org.apache.tomcat.util.net.niodempoint$SocketProcessor.doRun
java.lang.NullPointerException
以下是我如何修复它的方法：
Connector protocol="org.apache.coyote.http11.Http11Protocol"
          port="8443" maxThreads="200" scheme="https"
          secure="true" SSLEnabled="true"
          keystoreFile="/usr/share/tomcat.keystore"
          keystorePass="GODMYROCK"
          clientAuth="false" sslProtocol="TLS"
          URIEncoding="UTF-8"
          compression="force"
          compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"/>

我只是将连接器协议从org.apache.coyote.http11.Http11Protocol
更改为org.apache.coyote.http11.Http11NioProtocol
。因此，我的连接器此后看起来是这样的：
Connector protocol="org.apache.coyote.http11.Http11NioProtocol"
          port="8443" maxThreads="200" scheme="https"
          secure="true" SSLEnabled="true"
          keystoreFile="/usr/share/tomcat.keystore"
          keystorePass="GODMYROCK"
          clientAuth="false" sslProtocol="TLS"
          URIEncoding="UTF-8"
          compression="force"
          compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/css"/>

就这些
我希望这有帮助
不确定，但您的
元素现在可能需要一个子元素
？非常感谢您的详细回答。我的问题与法理学相似。解决方案只是将协议更改为：protocol=“org.apache.coyote.http11.Http11NioProtocol”
