Idea中构建Tomcat8源码开发环境
在研究SpringMVC源码之前得先看看Tomcat的源码（因为WEB应用要工作在容器中）。先构建Tomcat8的源码环境
下载
进入Tomcat官网https://tomcat.apache.org/download-80.cgi，选择tomcat8，下载下来是tomcat-8.5.49
导入到Idea中
准备
新建一个tomcat-8.5.49目录，再到其下新建一个deploy(是Tomcat的工作目录：-Dcatalina.home=x:\*.*deploy -Dcatalina.base=x:\*.*deploy)目录和导入源码目录，最终效果如下
deploy目录下的结构，除了可以复制的，其他目录直接新建
在tomcat-8.5.49目录下新建一个pom.xml
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">

<name>apache-tomcat-8</name>
<version>1.0</version>
<packaging>pom</packaging>
<modules>
<module>tomcat-8</module>
</modules>
</project>
在tomcat-8目录下新建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"

执行导入
File-Open-选择tomcat-8.5.49目录下的pom.xml文件，Idea会提示你，选择导入为Maven项目
导入成功之后如下所示：
中间会遇到的问题：
CookieFilter会报错，有三种解决方式：
1.在test源码目录下的util目录下新建CookieFitler
package util;import java.util.Locale;
import java.util.StringTokenizer;
/**
* Processes a cookie header and attempts to obfuscate any cookie values that
* represent session IDs from other web applications. Since session cookie names
* are configurable, as are session ID lengths, this filter is not expected to
* be 100% effective.
*
* It is required that the examples web application is removed in security
* conscious environments as documented in the Security How-To. This filter is
* intended to reduce the impact of failing to follow that advice. A failure by
* this filter to obfuscate a session ID or similar value is not a security
* vulnerability. In such instances the vulnerability is the failure to remove
* the examples web application.
*/
public class CookieFilter {
private static final String OBFUSCATED = "[obfuscated]";
private CookieFilter() {
// Hide default constructor
}
public static String filter(String cookieHeader, String sessionId) {
StringBuilder sb = new StringBuilder(cookieHeader.length());
// Cookie name value pairs are ";" separated.
// Session IDs don"t use ; in the value so don"t worry about quoted
// values that contain ;
StringTokenizer st = new StringTokenizer(cookieHeader, ";");
boolean first = true;
while (st.hasMoreTokens()) {
if (first) {
first = false;
} else {
sb.append(";");
}
sb.append(filterNameValuePair(st.nextToken(), sessionId));
}
return sb.toString();
}
private static String filterNameValuePair(String input, String sessionId) {
int i = input.indexOf("=");
if (i == -1) {
return input;
}
String name = input.substring(0, i);
String value = input.substring(i + 1, input.length());
return name + "=" + filter(name, value, sessionId);
}
public static String filter(String cookieName, String cookieValue, String sessionId) {
if (cookieName.toLowerCase(Locale.ENGLISH).contains("jsessionid") &&
(sessionId == null || !cookieValue.contains(sessionId))) {
cookieValue = OBFUSCATED;
}
return cookieValue;
}
}
2.删除test源码目录
3.删除报错的类
重新rebuild应该可以成功
运行
配置"run configuration"
点击：run-新建一个Application ，tomcat8.5.49
VM-OPTIONS
-Dcatalina.home=deploy-Dcatalina.base=deploy
-Djava.endorsed.dirs=deploy/endorsed
-Djava.io.tmpdir=deploy/temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=deploy/conf/logging.properties
-Dfile.encoding=UTF8
-Duser.language=en
-Duser.region=US
其中后面三项是设置启动后的乱码问题
此时运行还会报错，需要改一点代码
/*添加JSP支持*/ context.addServletContainerInitializer(new JasperInitializer(),null);
到这里应该所有的问题都解决了，启动，验证
熟悉的8080端口提示
可能不熟悉的tom猫的管理界面
