java - 华夫饼过滤器演示不起作用

Question

我正在尝试使用带有 java 的 waffle，使用 tomcat。当我尝试部署 waffle-filter-demo 时:https://github.com/Waffle/waffle/tree/master/Source/JNA/waffle-demo/waffle-filter

我在 tomcat 的日志中得到这个错误:

org.apache.catalina.core.StandardContext.filterStart Exception starting

Answer 1

我找到了解决方案!

1. 将 waffle_filter_demo.war 导入您的 eclipse。
2. 将目标运行时设置为您将使用的 apache tomcat 版本。
3. 引发一场新的 war 。
4. 在服务器上部署。
