tomcat源碼啓動

1. tomcat源碼下載地址

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

2. 解壓以及創建必要目錄和配置

解壓、新建catalina-home目錄，同時將目錄中的conf和webapps文件夾複製到catalina-home目錄中

3. 添加pom配置文件

<?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"

</project>

4. 把源碼導入eclipse，啓動Bootstrap

啓動類：Bootstrap
啓動選項中添加VM options

-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

刪除報錯類TestCookieFilter

5. 啓動tomcat成功，但是訪問網址報500

修改源碼org.apache.catalina.startup.ContextConfig
添加context.addServletContainerInitializer(new JasperInitializer(), null);

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

6. 打印日誌亂碼問題

虛擬機參數加入下面兩行，指定日誌用英文輸出即可

-Duser.lanaguage=en
-Duser.region=US

7. 遺留問題

tomcat自帶應用manager等頁面顯示亂碼問題，暫未解決。
