1 前言

一个问题，一篇文章，一出故事。
笔者今天遇到访问Tomcat服务遇到服务自动停止事宜，Tomcat日志有如下警告，

29-Aug-2022 09:23:18.505 WARNING [localhost-startStop-1] org.apache.catalina.startup.SetContextPropertiesRule.begin [SetContextPropertiesRule]{Context} Setting property 'antiJARLocking' to 'true' did not find a matching property.

2 最佳实践

2.1 寻找异常的配置文件

cd /usr/tomcat/apache-tomcat-8.5.81
grep -R 'antiJARLocking="true"'

可以搜索到如下配置文件已经配置’antiJARLocking=”true”‘，

webapps/project01/META-INF/context.xml:<Context antiJARLocking="true" path="/project01"/>
webapps/project02/META-INF/context.xml:<Context antiJARLocking="true" path="/project02"/>
webapps/project03/META-INF/context.xml:<Context antiJARLocking="true" path="/project03"/>

2.2 修复方法

cd /usr/tomcat/apache-tomcat-8.5.81
vim webapps/project01/META-INF/context.xml

配置按如下范例修改，

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="false" path="project01"/>
