struts2 错误 com.opensymphony.xwork2.util.finder.DefaultClassFinder

Question

我正在为一个项目使用 struts2。用户可以请求从网页下载文件，该请求将在后台处理。为了使它工作，我必须创建一个需要传入 servletContext 对象的调度程序。

//MockServletContext comes from the spring framework
MockServletContext context = new MockServletContext("file:directory");
//Initialize a dispatcher
StrutsTestCaseHelper.initDispatcher(context, map);

我的日志文件输出了一堆错误和一个“无法读取类”异常的示例：

ERROR [com.opensymphony.xwork2.util.finder.DefaultClassFinder] - Unable to read class [one.action.class.path]

还有一种例外：

java.io.FileNotFoundException: class path resource [one/resource/path/resource] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/home/user/dev/project/build_output/splice_links/da39a3ee5e6b4b0d3255bfef95601890afd80709/resources/resource.jar!one/resource/path/resource

我阅读了很多关于 stack-overflow 的帖子，但没有一篇对我有帮助。我需要在MockServletContext 中添加一些配置吗？ 谁能告诉我如何解决这个错误。如果您需要我发布更多文件/信息，请告诉我。

pom.xml 中的 asm 依赖：

 <dependency>
  <groupId>org.ow2.asm</groupId>
  <artifactId>asm</artifactId>
  <version>5.0.3</version>
</dependency>

Answer 1

出现以下错误，

java.lang.ArrayIndexOutOfBoundsException: 10792
    at org.objectweb.asm.ClassReader.readClass(Unknown Source)

我认为，您需要检查您的项目中是否使用了正确版本的 asm jar 文件。
