Struts + GAE java.security.AccessControlException：拒绝访问struts2-core-2.3.15.3.jar

Question

我在GAE中使用支撑架。我正在使用GAE 1.8和struts 2.3.15 jar文件。

在我的应用程序中，我面临这个异常

我做了很多搜索，有人说从sturts.xml文件中删除此属性值

<constant name="struts.devMode" value="true" />

有人说将值从true更改为false。我做到了，但是没用。请给出一个解决方案。我也更改了jar文件并使用2.1.8版本，但是在此过程中我在服务器启动时遇到了异常

我也在struts jar文件中使用以下jar文件

ognl-3.0.6.jar
sitemesh-2.4.2.jar
struts2-sitemesh-plugin-2.2.3.1.jar
xwork-core-2.3.15.3.jar

请指导我。

Answer 1

根据我的调查

java.security.AccessControlException：访问被拒绝（“ java.io.FilePermission”“
jar：file：\ E：\ eclipse \ Shaun \ Convergent \ war \ WEB-INF \ lib \
struts2-core-2.3.15.3.jar“”读”）

仅 当尝试在 Windows版 Google App Engine上运行Struts 2应用程序时 才会 发生异常。

在尝试将应用程序移植到GAE时，我在Windows上遇到了相同的问题，但是我无法在GNU /
Linux下重现它，也无法在使用appcfg.sh将其部署到Google服务器时重现–oauth2 update dist / myapp

为了解决在Windows版Google App Engine下运行时的问题， 我发现的唯一可行解决方案是实现
自定义插件/扩展点，该插件/扩展点实现以下接口com.opensymphony.xwork2.FileManager和com.opensymphony.xwork2.FileManagerFactory

在插件内部实现上述接口的类将覆盖Struts
2默认实例化的实现，即DefaultFileManager和DefaultFileManagerFactory

我创建的自定义文件插件具有三个主要组件：

1. 该支柱-plugin.xml的文件指定从插件的文件管理和FileManagerFactory执行应被视为默认
2. Struts2FileManagerFactoryOnGAE，FileManagerFactory接口的自定义实现，其中与DefaultFileManagerFactory实现唯一不同的是类名
3. Struts2FileManagerOnGAE，自定义FileManager实现，在其中进行了必要的更改，即 fileNeedsReloading（）方法和internal应该返回false，而support（）方法应该返回true。

另外，在应用程序的WEB-INF / web.xml中，我添加了： <init-param> <param- name>config</param-name> <param-value>struts-default.xml,struts- plugin.xml,struts.xml</param-value> </init-param>

因为我将Ant用作构建系统，所以我为自定义文件插件创建了新目标，该目标将插件的jar编译并复制到最终工件中：https : //gitlab.com/alibitek-java/Struts-
GAE /blob/master/build.xml

您可以在以下位置查看我的测试应用程序的源代码：https : //gitlab.com/alibitek-java/Struts-
GAE/tree/master

如果您想尝试一下，则可以运行：

ant dev_appserver

在build.xml中设置Google App Engine SDK的路径后，或者您可以在此处实时查看它http://struts-
gae.appspot.com/jsp/index.jsp

该应用程序的作用是：您需要猜测所生成的随机数，在尝试几次之后，它将显示一个提示，当您猜测该数字时，它将显示您已经猜测了多少次。
