Tomcat系列一.IDEA运行Tomcat源码

环境

IDEA2019.02
Tomcat-8.5.54

1.下载源码

https://tomcat.apache.org/download-80.cgi

2.修改配置

a.解压apache-tomcat-8.5.54-src.zip

b.在项目根目录下添加pom.xml文件, 内容如下:

<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                                   http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>
    </build>
</project>

c.创建catalina-home目录, 将源码中conf、webapps目录移动到catalina-home中

d.IEAD导入源码项目

3.启动

a.添加设置, Edit Configurations-Run/Denug Configurations-添加Application

b.设置VM option, 内容如下:
-Dcatalina.home=catalina-home
-Dcatalina.base=catalina-home
-Djava.endorsed.dirs=catalina-home/endorsed
-Djava.io.tmpdir=catalina-home/temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=catalina-home/conf/logging.properties

c.运行, 访问http://localhost:8080

4.异常处理

a.编译时, test/util/TestCookieFilter.java报下面错误:

解决方法:
注释掉整个类即可

b.访问http://localhost:8080时, 报下面错误:

解决方法:
在org.apache.catalina.startup.ContextConfig中手动初始化JSP解析器
