将Jetty资源库设置为嵌入在同一jar文件中的静态文件 [英] Setting Jetty resourcebase to static file embedded in the same jar file

问题描述

我正在尝试访问包装在同一.jar文件(testJetty.jar)中的静态资源(例如first.html)，该文件也具有启动码头(v.8)服务器(MainTest.java)的类. .我无法正确设置资源库.

I am trying to access static resource (eg. first.html) packed inside the same .jar file (testJetty.jar), which also has a class which starts the jetty (v.8) server (MainTest.java). I am unable to set the resource base correctly.

我的jar文件(testJetty.jar)的结构: testJetty.jar

The structure of my jar file (testJetty.jar): testJetty.jar

• first.html

• first.html

MainTest.java

MainTest.java

== 在本地计算机上工作正常，但是当我将其包装在jar文件中然后运行时，它不起作用，并显示"404:找不到文件"错误.

== Works fine on local machine, but when I wrap it in jar file and then run it, it doesn't work, giving "404: File not found" error.

我尝试使用以下值设置资源库，所有这些都失败了:

I tried to set the resourcebase with the following values, all of which failed:

a)尝试将其设置为.

a) Tried setting it to .

resource_handler.setResourceBase("."); // Results in directory containing the jar file, D:\Work\eclipseworkspace\testJettyResult

b)尝试从getResource获取它

b) Tried getting it from getResource

ClassLoader loader = this.getClass().getClassLoader();
File indexLoc = new File(loader.getResource("first.html").getFile());
String htmlLoc = indexLoc.getAbsolutePath();
resource_handler.setResourceBase(htmloc); // Results in D:\Work\eclipseworkspace\testJettyResult\file:\D:\Work\eclipseworkspace\testJettyResult\testJetty1.jar!\first.html

c)尝试获取Webdir

c) Tried getting the webdir

String webDir = this.getClass().getProtectionDomain()
        .getCodeSource().getLocation().toExternalForm();
resource_handler.setResourceBase(webdir); // Results in D:/Work/eclipseworkspace/testJettyResult/testJetty1.jar

这3种方法均无效.

任何帮助或替代方案将不胜感激

Any help or alternative would be appreciated

并非罕见，我找到了解决问题的方法.斯蒂芬在

Not unusually, I found a solution to my problem. The 3rd approach mentioned by Stephen in Embedded Jetty : how to use a .war that is included in the .jar from which Jetty starts? worked!

因此，我从Resource_handler更改为WebAppContext，其中WebAppContext指向相同的jar(testJetty.jar)，并且可以正常工作！

So, I changed from Resource_handler to WebAppContext, where WebAppContext is pointing to the same jar (testJetty.jar) and it worked!

    String webDir = MainTest.class.getProtectionDomain()
            .getCodeSource().getLocation().toExternalForm(); ; // Results in D:/Work/eclipseworkspace/testJettyResult/testJetty.jar
    WebAppContext webappContext = new WebAppContext(webDir, "/");
