在 web.xml 中，侦听器以这种方式配置：

<listener>
<listener-class>com.iss.congress.core.util.CongressHttpSessionListener</listener-class>

<listener>
<display-name>Hibernate Session Listener</display-name>
<listener-class>com.iss.congress.core.util.HibernateListener</listener-class>
</listener>

This is a case of java.lang.ClassNotFoundException: com.iss.congress.core.util.HibernateListenerwhich means that the class HibernateListeneris not present in the class path. Make sure that the jar containing this class is present in the WEB-INF/libfolder of your application.
在这种情况下，java.lang.ClassNotFoundException: com.iss.congress.core.util.HibernateListener该类HibernateListener不存在于类路径中。确保包含此类的 jar 存在于WEB-INF/lib应用程序的文件夹中。
If the class is present in the src folder then check the package name. Package names/Class Names are case-sensitive.
如果该类存在于 src 文件夹中，则检查包名称。包名/类名区分大小写。

There can be any of the following reasons:
可能有以下任何一个原因：
Either, your class file is not available on specified location (check your package_name/class_file_name.java)
OR, your file exist at specified location but there is an error in your file, that could be built (generate class file)
或者，您的类文件在指定位置不可用（检查您的 package_name/class_file_name.java）
或者，您的文件存在于指定位置，但您的文件中有错误，可以构建（生成类文件）
(for me, the reason for an issue was point no. 2.) The root cause of an issue was, I changed (upgraded) version of rest libraries, which caused an issue with existing class files.
（对我来说，问题的原因是第 2 点。）问题的根本原因是，我更改了（升级）rest 库的版本，这导致了现有类文件的问题。
I resolved an issue by adding/selecting proper apache tomcat server.
我通过添加/选择合适的 apache tomcat 服务器解决了一个问题。
Project Properties => Java Build Path => Add Library => Select
Server Runtime=> click Next and Select "Apache Tomcat" => Finish
项目属性 => Java 构建路径 => 添加库 => 选择
Server Runtime=> 单击下一步并选择“Apache Tomcat” => 完成
