【问题描述】：
如何修复错误：
java.lang.IllegalArgumentException: The main resource set specified [C:\temp\myApp.jar] is not valid
在嵌入式 Tomcat 应用程序中？
我相信我在上下文路径上做错了，但我不知道如何设置它。启动应用程序会按预期抛出 Eclipse 工作，但是当我尝试从命令提示符运行时，出现以下错误。我在下面粘贴了我尝试过的两种主要方法，App3 和 App4（通过命令提示符出现的错误相同）。我猜它在 Eclipse 中没有显示错误，因为必须有一些与 Context 相关的预定义参数，它使应用程序在 Eclipse 上运行，但在从命令提示符触发时崩溃。我已经检查过了，我使用的是完全相同的 JDK。
我相信问题出在上下文，因为即使它运行 throw Eclipse 和第二个试探性 (App4)，如果我检查 C:\temp，那里根本没有战争。
一个暂定（不带setAppBase）：
import java.io.File;
import java.net.URISyntaxException;
import javax.servlet.ServletException;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.startup.Tomcat;
public class App3 {
public static void main(String[] args) throws ServletException,
LifecycleException, URISyntaxException {
String runningJarPath = App.class.getProtectionDomain().getCodeSource() .getLocation().toURI().getPath().replaceAll("\\\\", "/");
String contextPath = "/";
File rootF = new File(runningJarPath);
Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
tomcat.setBaseDir(".");
tomcat.addWebapp(contextPath, rootF.getAbsolutePath());
tomcat.start();
tomcat.getServer().await();
}
}
其他暂定（使用 setAppBase 到特定文件夹）：
import java.io.File;
import java.net.URISyntaxException;
import javax.servlet.ServletException;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.startup.Tomcat;
public class App4 {
public static void main(String[] args) throws URISyntaxException,
ServletException, LifecycleException {
String runningJarPath = App4.class.getProtectionDomain()
.getCodeSource().getLocation().toURI().getPath()
.replaceAll("\\\\", "/");
String contextPath = "/";
File rootF = new File(runningJarPath);
Tomcat tomcat = new Tomcat();
tomcat.setPort(8080);
tomcat.setBaseDir("C\\temp");
//the next line was added along with ***Edited 2
tomcat.addWebapp(tomcat.getHost(), "/App", "C:\\temp\\");
//the next two lines commented was commented along with ***Edited 2
//tomcat.addWebapp(contextPath, rootF.getAbsolutePath());
tomcat.getHost().setAppBase("C\\temp");
tomcat.start();
//tomcat.addWebapp(tomcat.getHost(), "/App", "C:\\temp\\");//
tomcat.getServer().await();
}
}

我为暂定 1 添加了整个日志。关于暂定 2，我通过将“addWeApp(tomcat.getHost...”) 基本向上移动并评论另外两个使用 addWeb 的方式进行了小改动。在那之后，在试探 2 中，我可以通过 java -jar 启动应用程序......但只是在尝试 localhost:8080/myRequestedMapValue 时我得到一个空白页。只是为了突出一点，如果我同时尝试，试探 1 和 2通过 Eclipse，我将成功打开 localhost:8080/myRequestedMapValue 它将打开一个非常简单的 index.jsp，由一个非常简单的控制器路由（@Controller 加上 @RequestMapping(..get)

如果服务器启动这个问题就解决了。请投票支持任何有助于并针对当前问题提出新问题的回复。重要的是您要指定：您的 jar 结构、整个 web.xml 以及您获得 404 的 url
