First port of call : I'd say your web.xml has declared a filter, and you've got the wrong class name in the definition
第一个调用端口：我会说你的 web.xml 已经声明了一个过滤器，而你在定义中得到了错误的类名

In your web application, there is a missing class sevices.authentication.SessionFilter.
在您的 Web 应用程序中，缺少一个 class sevices.authentication.SessionFilter。
This means that either:
这意味着：
- The class containing
sevices.authentication.SessionFilteris not found in yourWEB-INF/libdirectory, OR - Your class
sevices.authentication.SessionFilter, in your web application, didn't compile intoWEB-INF/classesfolder.
sevices.authentication.SessionFilter在您的WEB-INF/lib目录中找不到包含的类，或者- 您
sevices.authentication.SessionFilter的 web 应用程序中的class没有编译到WEB-INF/classes文件夹中。
Make sure your code compiles with no errors and deploys correctly (WAR file).
确保您的代码编译无误并正确部署（WAR 文件）。
