[Java知识库]Tomcat

1、下载源码；

在官网选择对应的版本下载源码，这里下载的是8.5.70，解压打开文件

2、新建home文件夹，将源码中的conf和webapp文件夹放到新的home文件夹下；

3编写pom.xml文件；

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

4、添加Application并设置VM参数；

-Dcatalina.home=F:/idea_project/tomcat/apache-tomcat-8.5.70-src/apache-tomcat-8.5.70-src/home
-Dcatalina.base=F:/idea_project/tomcat/apache-tomcat-8.5.70-src/apache-tomcat-8.5.70-src/home
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=F:/idea_project/tomcat/apache-tomcat-8.5.70-src/apache-tomcat-8.5.70-src/home/conf/logging.properties

5、点击运行，打开浏览器输入localhost:8080；

发现报错了

在ContextConfig.java文件的configureStart方法内webConfig()下面新增一行代码

context.addServletContainerInitializer(new JasperInitializer(), null);

6、再次浏览localhost:8080；
