在将第三方库添加到您的应用程序时，必须确保它们位于应用程序的构建路径中.对于Web应用程序，每个第三方库都必须位于应用程序的 WEB-INF/lib 中，以便在部署到服务器(Tomcat，JBoss等)时可以识别并加载它们运行您的应用程序.

When adding third party libraries to your application, you must be sure they are in the Build Path of your application. In case of web applications, every third party library must be inside the WEB-INF/lib of the application so when deployed to the server (Tomcat, JBoss, etc.) they can be recognized and loaded when running your application.
