在运行java中HttpSessionListener监听器时,运行报错:
严重: StandardWrapper.Throwable
com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes.
以下是监听器程序:
package Listener1; import javax.servlet.annotation.WebListener; import javax.servlet.http.HttpSessionEvent; import javax.servlet.http.HttpSessionListener; @WebListener public class HSL implements HttpSessionListener { private int ub; @Override public void sessionCreated(HttpSessionEvent se) { ub++; se.getSession().getServletContext().setAttribute("ub", ub); } @Override public void sessionDestroyed(HttpSessionEvent se) { ub--; se.getSession().getServletContext().setAttribute("ub", ub); } } 求大神指点哪里错误!!!!!非常感谢!!!!
