**这是我的com.cityparlor.web.listener.WebContextListener

**

 package com.cityparlor.web.listener;

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.WebApplicationContext;

import com.cityparlor.service.collect.CollectEnrollService;

public class WebContextListener extends ContextLoaderListener {
    @Autowired
    private CollectEnrollService collectEnrollService;
    public WebApplicationContext initWebApplicationContext(ServletContext servletContext) {
        System.out.println("cityparlor project start......");       
        return super.initWebApplicationContext(servletContext);
    }

    public void contextInitialized(ServletContextEvent event) { 
        //ServletContext context = event.getServletContext(); 
        super.contextInitialized(event); 

        System.out.println("cityparlor project initialized ...............");
    }
}

#在线等# 求大佬

Answer 1

应该是类没找到，你可以写个servlet，在servlet中手动用Class.forName("com.cityparlor.web.listener.WebContextListener");看看能不能加载。
如果不能加载你手动将WebContextListener.class拷贝到WEB-INF\class下，按包名创建相应的目录最终将WebContextListener.class文件放进去，重启tomcat再试试。
再者检查WebContextListener所依赖的类是否存在jar包没导入的情况
