虽然我可以在localhost:8080上看到Tomcat的启动页,但我在使用JSSE连接器时遇到了问题。我在Ubuntu 16.04的JDK 9.0.1上使用Tomcat 9.0.2。
我的连接器是:
<Connector port="8443"
protocol="org.apache.coyote.http11.Http11NioProtocol"
sslImplementationName="org.apache.tomcat.util.net.jsse.JSSEImplementation"
maxThreads="150"
SSLEnabled="true"
scheme="https"
secure="true" >
<SSLHostConfig>
<Certificate certificateKeystoreFile="../.keystore"
certificateKeystorePassword="changeit"
certificateKeyAlias="tomcat"
type="RSA" />
</SSLHostConfig>
</Connector>
但是,在浏览器上转到localhost:8443时,我会看到以下内容:
在Firefox上:
“连接已重置。加载页面时,与服务器的连接已重置。”
关于铬:
“此页面不工作。localhost未发送任何数据。ERR\u EMPTY\u响应”
我看到密钥库文件被正确读取。当我这样做时:
openssl s_client -debug -connect localhost:8443
输出如下:

在
catalina.out
日志文件中,我发现每当我尝试通过浏览器localhost:8443访问时,都会发生NPE:
05-Jan-2018 08:48:06.848 SEVERE [https-jsse-nio-8443-exec-1] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun

此异常重复10次,重复之间的唯一区别是子字符串“exec-<NUMBER>”在第一行中,数字范围从1到10(在上面的示例中,它是1)。
为什么多伦方法会抛出NPE对我来说是个谜。我尝试了许多配置组合,但都没有成功。发生了什么?
