ThreadLocalLeakPreventionListener最近被添加到 tomcat。它在 tomcat 7 以及最新版本的 tomcat 6 中可用。确保您拥有最新的 tomcat 6，并进行全新安装（您的安装可能具有来自新版本和旧版本的罐子）The
ThreadLocalLeakPreventionListenerwas added recently to tomcat. It is available in tomcat 7 as well as the latest version(s) of tomcat 6. Make sure you have the latest tomcat 6, with a clean installation (your installation might have theserver.xmlfrom the new version and the jars from the older one)即使我遇到了同样的问题。您需要做的是，转到服务器选项卡并左键单击 Apache 服务器，然后单击属性。在那里您可以看到指向[工作区元数据]的位置。单击切换位置。它将切换到 Apache 位置 /Servers/Tomcat xxx。应用更改并保存。
even i faced the same issue.What you need to do is, go to servers tab and left click on Apache server and click on properties. There you can see Location pointing to [workspace metadata]. Click on switch Location. It will switch to Apache location /Servers/Tomcat xxx.Apply the changes and save.
如果您在 server.xml 中使用该类，则需要将其删除以消除错误/异常。
If you are using the class in server.xml you need to remove it to get rid of the error/Exception.
您的 web.xml 包含侦听器的条目，其代码是在 Tomcat 7.0.6 及更高版本中添加的，但您的 tomcat 比该条目更旧 -
org.apache.catalina.core.ThreadLocalLeakPreventionListener
Your web.xml contains entry for a listener whose code was added in Tomcat 7.0.6 and onwards, but your tomcat is older than that -
