Spring Web＆＃34; java.lang.NoClassDefFoundError：antlr / RecognitionException]具有根本原因＆＃34;错误

Question

我有一个动态的web项目，我没有使用Maven（所以，我没有pom.xml）。我的控制器适用于我为测试目的而创建的HelloWorldController。我收到了以下错误，我认为这与服务或JpaDao课程相关。我还将添加这些文件。如果您还有其他需要，我还可以添加和更新我的帖子。提前谢谢。

我有这样的错误日志：

Answer 1

java.lang.ClassNotFoundException：antlr.RecognitionException显示缺少antlr lib。添加它并完成它:)
