Tomcat 启动 远程调试

首先需要下载tomcat的源码，然后创建一个java project 导入tomcat源代码

像下图：到如下层级：C:\Users\Administrator\Downloads\apache-tomcat-7.0.47-src\apache-tomcat-7.0.47-src\java

然后修改tomcat/bin/startup.bat

添加如下：suspend=y 就可以调试tomcat启动过程。

SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8788

打开你想调试的tomcat源码：

eclipse

然后启动就可以看见调试的代码了。

import java.util.Enumeration;

import org.apache.commons.compress.archivers.jar.JarArchiveEntry;
import org.apache.commons.compress.archivers.zip.ZipFile;


public class ZipDemo {

	public static void main(String[] args) throws Exception {
		//use apache commons-commpress for zip...
		String file = "C:\\Users\\Administrator\\Downloads\\apache-tomcat-7.0.54\\中文apache-tomcat-7.0.54\\lib\\annotations-api.jar";
		String file2 ="jar:file:/C:/Users/Administrator/Downloads/apache-tomcat-7.0.54/中文apache-tomcat-7.0.54/webapps/examples/WEB-INF/lib/poi-contrib-3.2-FINAL-20081019.jar!/";
		System.out.println(file2.substring(10));
		ZipFile zf = new ZipFile(file2, "utf-8");
		Enumeration e = zf.getEntries();
		while(e.hasMoreElements())
		{
			System.out.println(e.nextElement());
		}
		zf.closeQuietly(zf);
//		en = new JarArchiveEntry(file);
//		en.get
	}
	

}
