我在通过 Eclipse 和 Tomcat 部署基本 Web 应用程序时遇到了一个奇怪的问题
错误 -
SEVERE: Allocate exception for servlet DeCommServlet
java.lang.ClassNotFoundException: com.authentication.DeCommServlet
at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1714)
但是，应用程序仍会访问 DeCommServlet doPost() 方法，并且 tomcat 保持部署但出现该错误。
小服务程序：
<servlet>
<servlet-name>DeCommServlet</servlet-name>
<servlet-class>com.authentication.DeCommServlet</servlet-class>
</servlet>
<!-- Servlet Mappings -->
<servlet-mapping>
<servlet-name>DeCommServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
servlet 类是正确的链接，但仍然出现此错误。我在任何 lib 文件夹中都没有任何内容，但是在应用程序属性中，我在 Build Path >> Libraries 添加了 Apache Tomcat Lib
有没有人见过这个？
DeCommServlet 的代码：
@WebServlet("/DeCommServlet")
public class DeCommServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public DeCommServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.println("sdf");
System.out.println("ddd");
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
* response)
*/
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
request.getUserPrincipal().getName();
response.sendRedirect("http://www.google.com");
}
