弹簧3.0.5 - java.awt.HeadlessException - com.trend.iwss.jscan

Question

我正在将一个应用程序从2.5.6版本迁移到3.0.5版本。首先，我必须将-Djava.awt.headless=true参数添加到虚拟机中，当我运行任何一个应用程序时，我在日志跟踪中得到以下几次：

INFO: Loading XML bean definitions from class path resource [ar/com/test/spring/applicationContext.xml]
-->> returning Frame NULL
java.awt.HeadlessException
at java.awt.GraphicsEnvironment.checkHeadless(Graphic sEnvironment.java:159)
at java.awt.Window.<init>(Window.java:407)
at java.awt.Frame.<init>(Frame.java:402)
at java.awt.Frame.<init>(Frame.java:367)
.....

如何在需要添加trace?...Do参数以避免此错误的Djava.awt.headless=true中避免此错误？

下面是一个小样本：

package ar.com.test.spring;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlAp plicationContext;

public class Test {
   private static final String[] LOCATIONS = {"ar/com/test/spring/applicationContext.xml"};

   public static void main(String[] args) {
      ApplicationContext context = new ClassPathXmlApplicationContext(LOCATIONS);
   }
}

applicationContext.xml含量

Answer 1

今天我也遇到了类似的问题。我想和大家分享我的研究，也许这会对某些人有所帮助。

症状：

当您使用任何java软件时，都会弹出"Applet警报“"Applet试图.”但你知道你不使用任何小程序。

如果您按弹出时的“停止小程序”按钮，或使用Djava.awt.headless=true或其他方式抑制弹出，您将在日志中看到一个错误，如

您可以看到弹出是由com.trend.iwss.jscan.runtime包中的代码创建的。

的原因：

您正在使用从internet下载的jar，该jar是通过趋势微InterScan网络安全套件/设备代理下载的。这个代理在你从互联网下载的所有罐子中做钩子，这样当他们试图访问文件时，你会看到弹出的"Applet警报“。

您可以通过com.trend.iwss.jscan.runtime包之前的最后堆栈跟踪入口来确定受影响的jar。(在我的例子中，它是来自commons-digester.jar的org.apache.commons.digester.Digester，在masch的例子中是来自spring.jar的org.springframework.core.io.support.PropertiesLoaderUtils )

解决方案：

你有两个选择：

• 您可以下载存档的jar文件。所以他们不会受到代理的影响。
• 您可以将代理配置为不修改下载jar文件。

Answer 2

这是关键的部分：

at org.springframework.core.io.support.PropertiesLoaderUtils.loadAllProperties(PropertiesLoaderUtils.java:108)

您的JVM附带了一些奇怪的安全软件，用于拦截Spring中的调用。它似乎要求AWT已启动并运行，以便它可以显示一个对话框，这是愚蠢的，而您的headless配置设置使它失败。

您为什么一开始就添加Djava.awt.headless=true？没有它会发生什么？

Answer 3

at com.trend.iwss.jscan.runtime.PolicyRuntime.showAllowDialog确实说了这一切，有些策略检查代码想要显示一个确认对话框，或者"jscan“配置错误，或者它只用于交互式使用va一个Swing UI。正如讨论中所显示的那样，这个问题是由作为Java ppplet运行的代码引起的。Applet的安全限制导致执行VM (通过SWING UI)交互地向用户询问访问本地文件的权限。本地文件和applet无论如何都不能工作，所以最好的选择是您需要将您的资源(配置文件等)绑定到applet中，并通过ClassLoader (例如getClass().getClassLoader().getResource("/path/to/props.properties"))加载它们。
