在引入项目时，替换Tomcat lib包导致ClassNotFound错误。通过删除server.xml中监听内存泄露的配置，成功解决Tomcat启动问题。学会排错方法，提升技术能力。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

今天在引入项目的时候，将tomcat下的lib包替换，然后引入项目需要的包。启动tomcat时，发现做了这个错误：

.ClassNotFoundException: org.apache.catalina.core.JreMemoryLeakPreventionListener


很郁闷的时候，看到了

警告: Catalina.start using conf/server.xml:

于是看了下server.xml，原来只要在server.xml中把

<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />

这句话去掉好了。


这句话是说要监听内存泄露，具体为什么去掉就好我也不太明白。

也许是别人给我的jar包有点问题，其中少了这个类，不过学会这种排错的方法，挺开心的。

本文我们来分析分析应用服务器的内存泄露的问题，看看Tomcat是如何应对这个问题的；首先，来看看内存泄露这个词，内存对于java程序来说，即指JVM内存，而我们知道JVM的内存泄露是有很多种情况的；一种情况，class泄露是perm区的内存，此种场景就是当应用服务器的类特别多的时候，perm区的容量也是由限度的，会撑爆；另外一种就是，java对象太多，新生代，老年代等对象存储区太多，fu...

Tomcat的JreMemoryLeakPreventionListener监听周期性频繁执行full gc
gao_xianglong的自言自语

昨天下午公司有个后台管理系统，部署后，今天早上观察来看，发现gc.log中频繁的执行full gc，活动轨迹很明确，都是一个小时执行一次整个空间的full gc，但明显内存占用率还远远没有达到阈值，从日志上可以明确判断出应该是执行System.gc后导致的，因此回忆了下，貌似记得Tomcat的server.xml中有一个防止内存溢出的JreMemoryLeakPreventionListene...

窥探Tomcat整体架构，server.xml常用配置解析
公众号：该用户快成仙了

一、前言 server.xml配置，是Tomcat启动配置，从配置结构可以看出Tomcat的整体架构。如果能够了解其常用配置项，对Tomcat有一个高屋建瓴的把握，然后再庖丁解牛，一步步深入源码中分析每一个核心功能的实现细节，这样会有事半功倍的效果。 1.1 server.xml配置示例 如上图 server.xml 配置，最外层是一个 Server，代表 Tomcat的运行实例。Server 里有一些监听器 Listener，一个不知道干啥的 GlobalNamingResourc...

Tomcat最初是由Sun的软件架构师詹姆斯·邓肯·戴维森开发的。后来他帮助将其变为开源项目，并由Sun贡献给Apache软件基金会。Tomcat服务器是一个免费的开放源代码的Web应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。
