struts2错误com.opensymphony.xwork2.util.finder.DefaultClassFinder
提问于 2018-01-18 09:51:42
我正在为一个项目使用struts2。用户可以请求从网页下载文件，此请求将在后台处理。为了让它工作，我必须创建一个dispatcher，它需要传入一个servletContext对象。
//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"unable to read class“异常的示例：

pom.xml中的asm依赖项：
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>

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。
