Question

我遇到了应用程序缓慢问题，它抛出了java异常并且无法连接到数据库＆＃39;。我最初调查过它来自一个catch块，它的try块只是执行数据库连接并运行一些查询。我仍然不知道问题是什么。我也查看了tomcat的catalina.log文件，我在那里遇到了几个问题。这些问题可能与应用程序的缓慢无关，但那些问题很多。我列出了catalina.log中报告的所有问题，以便您可以帮助我。非常感谢提前..

Answer 1

＆＃34; ERROR main org.apache.coyote.http11.Http11Protocol - 初始化端点时出错 java.net.BindException：已在使用的地址：xxxx＆＃34;

您正在尝试在已经使用的端口中启动tomcat。尝试使用netstat查找哪个应用程序正在使用此端口（XXXX）。

Tomcat catalina.log捕获了许多例外
