阅读 Tomcat 源码第一关--把 Tomcat 运行起来

1、下载 Tomcat 源码

Tomcat 开源项目地址：https://github.com/apache/tomcat

2、添加 Tomcat 依赖的 jar 包

直接建立 Maven 工程导入 jar 包。在项目根目录新建 pom.xml 文件

<?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">    <modelVersion>4.0.0</modelVersion>    <groupId>org.apache.tomcat</groupId>    <artifactId>Tomcat8.0</artifactId>    <name>Tomcat8.0</name>    <version>8.0</version>    <build>        <finalName>Tomcat8.0</finalName>        <sourceDirectory>java</sourceDirectory>        <testSourceDirectory>test</testSourceDirectory>        <resources>            <resource>                <directory>java</directory>            </resource>        </resources>        <testResources>            <testResource>                <directory>test</directory>            </testResource>        </testResources>        <plugins>            <plugin>                <groupId>org.apache.maven.plugins</groupId>                <artifactId>maven-compiler-plugin</artifactId>                <version>2.3</version>                <configuration>                    <encoding>UTF-8</encoding>                    <source>1.7</source>                    <target>1.7</target>                </configuration>            </plugin>        </plugins>    </build>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>4.11</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>ant</groupId>            <artifactId>ant</artifactId>            <version>1.7.0</version>        </dependency>        <dependency>            <groupId>wsdl4j</groupId>            <artifactId>wsdl4j</artifactId>            <version>1.6.2</version>        </dependency>        <dependency>            <groupId>javax.xml</groupId>            <artifactId>jaxrpc</artifactId>            <version>1.1</version>        </dependency>        <dependency>            <groupId>org.eclipse.jdt.core.compiler</groupId>            <artifactId>ecj</artifactId>            <version>4.5</version>        </dependency>        <!-- https://mvnrepository.com/artifact/org.easymock/easymock -->        <dependency>            <groupId>org.easymock</groupId>            <artifactId>easymock</artifactId>            <version>3.2</version>            <scope>test</scope>        </dependency>    </dependencies></project>

3、配置 idea 。

目录如下

4、配置 Tomcat 启动参数

配置启动类为 Bootstrap。

配置 虚拟机参数为

-Dcatalina.home=D:\ljc\code\tomcat-source-maven-master\tomcat-source-maven-master
-Dcatalina.base=E:\code\java\javaweb\program\tomcat-source-maven
-Djava.endorsed.dirs=E:\code\java\javaweb\program\tomcat-source-maven
-Djava.io.tmpdir=E:\code\java\javaweb\program\tomcat-source-maven
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=E:\code\java\javaweb\program\tomcat-source-maven

将涉及到的目录改为自己 Tomcat 源码所在的目录就好了。

5、运行一下
