Java 错误：未能初始化与ProtocolHandler["；http-apr-8080"；关联的端点

我正在尝试在露天进行外部SSO。在share-config-custom.xml中完成配置，并更新了alfrsco-global.properties。试图通过单击另一个应用程序中的链接（附加了alfresco票证的URL）打开用户仪表板。创建了一个特殊的SSO筛选器以获取票证并在连接器会话中设置alfTicket参数

为什么会出现这种错误？

单击另一个应用程序的链接后，我可以看到我的筛选器正在执行，但SSO没有发生。

我尝试更改最初分配的端口号8080。通过执行以下步骤进行更改： 编辑文件夹conf/中的server.xml： 替换下面的代码-

 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" /> 

代码为：

 <Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

然后试着跑步。这对我很有效。

您似乎已经在8080端口上列出了一些内容，所以tomcat无法声明它。你有没有试着检查那是什么，并阻止它？是的。我得到了它。我停止了这个过程并尝试了。
