Caused by: java.lang.ClassNotFoundException: org.springframework.context.event.EventListenerFactory

看样子是没找到类。
导包使用maven还是手动导的?
看看有没有这个类
如果有,再看看项目部署目录下,有没有这个类

求助:ssm的maven项目tomcat插件启动成功,但是无法访问的问题!
问题描述: springmvc+mybatis项目,tomcat插件成功启动后,访问报404的错误。 个人排查: 1.将其独立部署到tomcat服务器而不用tomcat插件可以成功启动并访问。 2.tomcat插件启动成功后,target下的classes目录下面没有配置文件,但是有class文件。buildpath中已经配置输出文件夹为target/classes,仍然无效。 tomcat插件配置: ``` <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <update>true</update> <!-- 热部署 --> <charset>utf-8</charset> <!-- 设置字符集 --> <uriEncoding>UTF-8</uriEncoding><!-- 设置uri编码 --> <port>8080</port> <!-- 设置端口 --> <path>/</path><!-- 设置默认访问应用的路径 --> </configuration> </plugin> </plugins> ``` 前端控制器配置: ``` <!-- 前端控制器 --> <!-- The front controller of this Spring Web application, responsible for handling all application requests --> <servlet> <servlet-name>springDispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:springmvc/springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- Map all requests to the DispatcherServlet for handling --> <servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> ``` controller: ``` @Controller public class UserController { @Autowired private UserService userService; @RequestMapping("/") public String hello() { return "index"; } @RequestMapping("/user") @ResponseBody public List<User> getUserList() { List<User> list = userService.getUserList(); return list; } } ``` 访问url:localhost:8080,正常应该跳转到index.jsp界面,实际输出:`No mapping found for HTTP request with URI [/] in DispatcherServlet with name 'springDispatcherServlet'`。 # 求助!!!
ssm不重启Tomcat使修改后的spring.xml配置生效?
![图片说明](https://img-ask.csdn.net/upload/201912/18/1576655811_472298.png) 在开发ssm项目时,在发布之后会动态修改spring的配置文件,但是每次修改之后都需要重启Tomcat服务才可以生效,有没有办法不重启Tomcat使配置生效?(注:没有使用maven;修改Tomcat的reloadable属性测试会出现错误不可以)
Maven项目SSM整合后,tomcat可启动,但localhost:8080/无法访问

ssm框架demo遇到的问题
各位老哥们大家好,我是一名大二学生,自学Java一年半了,进步很慢,在ssm框架上遇到了问题,认识的人少,这个问题没人指点我,我很难再往后学习。 下面描述一下我遇到的问题吧:我比较抵触写jsp,所以从javaweb开始就尝试前后端分离,在学习ssm框架时,讲师用的都是jsp,我以为只要把springmvc的视图解析器中suffix配置成.html就行了,事情却没那么简单,项目一运行就报404,按理应该默认去找index.html,但是却直接报错,希望老哥们给我分析一下我哪里有错误。希望前辈能指导一下,谢谢了 ## 1:创建项目,我用的是IDEA,创建时选择的是Maven的webapp骨架。 ## 2:导入pom依赖 ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <packaging>war</packaging> <name>register</name> <groupId>xyz.peterparker</groupId> <artifactId>register</artifactId> <version>1.0-SNAPSHOT</version> <build> <plugins> <plugin> <groupId>org.mortbay.jetty</groupId> <artifactId>maven-jetty-plugin</artifactId> <version>6.1.7</version> <configuration> <connectors> <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"> <port>8888</port> <maxIdleTime>30000</maxIdleTime> </connector> </connectors> <webAppSourceDirectory>${project.build.directory}/${pom.artifactId}-${pom.version} </webAppSourceDirectory> <contextPath>/</contextPath> </configuration> </plugin> </plugins> </build> <properties> <spring.version>5.2.1.RELEASE</spring.version> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <mybatis.version>3.4.5</mybatis.version> </properties> <dependencies> <!--dependency> <groupId>xyz.peterparker</groupId> <artifactId>[the artifact id of the block to be mounted]</artifactId> <version>1.0-SNAPSHOT</version> </dependency--> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.6.8</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>c3p0</groupId> <artifactId>c3p0</artifactId> <version>0.9.1.2</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>javax.annotation</groupId> <artifactId>jsr250-api</artifactId> <version>1.0</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.16</version> </dependency> </dependencies> </project> ``` ## 3:创建包结构 ![图片说明](https://img-ask.csdn.net/upload/202002/19/1582083667_469404.png) ## 4:编写web.xml ``` <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <!-- 更改applicationContext的默认位置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 配置监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> <!-- 配置前端控制器 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <!-- 配置解决中文乱码的过滤器 --> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app> ``` ##

ssm项目部署tomcat问题
自己建立了spring+springmvc+mybatis整合的小项目,用的是maven。目录如下图![项目结构](https://img-ask.csdn.net/upload/201711/09/1510208296_486345.png) maven--update project 操作后就能正常启动tomcat,但是会报java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener,查了百度,说是tomcat下的项目没有lib,然后照着操作,properties-->add maven dependencies ,操作完查看tomcat下的项目web—Inf下有lib,但是启动tomcat又报错。报错如图![报错图片](https://img-ask.csdn.net/upload/201711/09/1510208538_77234.png)。然后我试着又maven ---> update project ,启动没问题,但是tomcat下的项目目录又没了lib包。 至今找不到问题,求解?另外为什么能tomcat启动了,然后我locatlhost:8080/TestProject/index.jsp 报了404 。无从下手,小白求指导

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

死磕YOLO系列,YOLOv1 的大脑、躯干和手脚
YOLO 是我非常喜欢的目标检测算法,堪称工业级的目标检测,能够达到实时的要求,它帮我解决了许多实际问题。 这就是 YOLO 的目标检测效果。它定位了图像中物体的位置,当然,也能预测物体的类别。 之前我有写博文介绍过它,但是每次重新读它的论文,我都有新的收获,为此我准备写一个系列的文章来详尽分析它。这是第一篇,从它的起始 YOLOv1 讲起。 YOLOv1 的论文地址:https://www.c

记一次腾讯面试:进程之间究竟有哪些通信方式?如何通信? ---- 告别死记硬背
有一次面试的时候,被问到进程之间有哪些通信方式,不过由于之前没深入思考且整理过,说的并不好。想必大家也都知道进程有哪些通信方式,可是我猜很多人都是靠着”背“来记忆的,所以今天的这篇文章,讲给大家详细着讲解他们是如何通信的,让大家尽量能够理解他们之间的区别、优缺点等,这样的话,以后面试官让你举例子,你也能够顺手拈来。 1、管道 我们来看一条 Linux 的语句 netstat -tulnp | gr...
20行Python代码爬取王者荣耀全英雄皮肤
引言 王者荣耀大家都玩过吧,没玩过的也应该听说过,作为时下最火的手机MOBA游戏,咳咳,好像跑题了。我们今天的重点是爬取王者荣耀所有英雄的所有皮肤,而且仅仅使用20行Python代码即可完成。 准备工作 爬取皮肤本身并不难,难点在于分析,我们首先得得到皮肤图片的url地址,话不多说,我们马上来到王者荣耀的官网: 我们点击英雄资料,然后随意地选择一位英雄,接着F12打开调试台,找到英雄原皮肤的图片
网络(8)-HTTP、Socket、TCP、UDP的区别和联系
TCP/IP协议是传输层协议,主要解决数据如何在网络中传输,而HTTP是应用层协议,主要解决如何包装数据。 一、TCP与UDP的不同 1. 是否需要建立连接。 UDP在传送数据之前不需要先建立连接;TCP则提供面向连接的服务; 2. 是否需要给出确认 对方的传输层在收到UDP报文后,不需要给出任何确认,而 TCP需要给出确认报文,要提供可靠的、面向连接的传输服务。 3.虽然UDP不提供可靠交...

防劝退!数据结构和算法难理解?可视化动画带你轻松透彻理解!
大家好,我是 Rocky0429,一个连数据结构和算法都不会的蒟蒻… 学过数据结构和算法的都知道这玩意儿不好学,没学过的经常听到这样的说法还没学就觉得难,其实难吗?真难! 难在哪呢?当年我还是个小蒟蒻,初学数据结构和算法的时候,在忍着枯燥看完定义原理,之后想实现的时候,觉得它们的过程真的是七拐八绕,及其难受。 在简单的链表、栈和队列这些我还能靠着在草稿上写写画画理解过程,但是到了数论、图...
西游记团队中如果需要裁掉一个人,会先裁掉谁?
2019年互联网寒冬,大批企业开始裁员,下图是网上流传的一张截图: 裁员不可避免,那如何才能做到不管大环境如何变化,自身不受影响呢? 我们先来看一个有意思的故事,如果西游记取经团队需要裁员一名,会裁掉谁呢,为什么? 西游记团队组成: 1.唐僧 作为团队teamleader,有很坚韧的品性和极高的原则性,不达目的不罢休,遇到任何问题,都没有退缩过,又很得上司支持和赏识(直接得到唐太宗的任命,既给
开挂的人生!那些当选院士,又是ACM/IEEE 双料Fellow的华人学者们
昨日,2019年两院院士正式官宣,一时间抢占了各大媒体头条。 朋友圈也是一片沸腾,奔走相告,赶脚比自己中了大奖还嗨皮! 谁叫咱家导师就是这么厉害呢!!! 而就在最近,新一年度的IEEE/ACM Fellow也将正式公布。 作为学术届的顶级荣誉,不自然地就会将院士与Fellow作比较,到底哪个含金量更高呢? 学术君认为,同样是专业机构对学者的认可,考量标准不一,自然不能一概而论。 但...
聊聊C语言和指针的本质
坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...

究竟你适不适合买Mac?
我清晰的记得,刚买的macbook pro回到家,开机后第一件事情,就是上了淘宝网,花了500元钱,找了一个上门维修电脑的师傅,上门给我装了一个windows系统。。。。。。 表砍我。。。 当时买mac的初衷,只是想要个固态硬盘的笔记本,用来运行一些复杂的扑克软件。而看了当时所有的SSD笔记本后,最终决定,还是买个好(xiong)看(da)的。 已经有好几个朋友问我mba怎么样了,所以今天尽量客观

程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外
(经验分享)作为一名普通本科计算机专业学生,我大学四年到底走了多少弯路
今年正式步入了大四,离毕业也只剩半年多的时间,回想一下大学四年,感觉自己走了不少弯路,今天就来分享一下自己大学的学习经历,也希望其他人能不要走我走错的路。 (一)初进校园 刚进入大学的时候自己完全就相信了高中老师的话:“进入大学你们就轻松了”。因此在大一的时候自己学习的激情早就被抛地一干二净,每天不是在寝室里玩游戏就是出门游玩,不过好在自己大学时买的第一台笔记本性能并不是很好,也没让我彻底沉...

互联网公司的裁员,能玩出多少种花样?
裁员,也是一门学问,可谓博大精深!以下,是互联网公司的裁员的多种方法:-正文开始-135岁+不予续签的理由:千禧一代网感更强。95后不予通过试用期的理由:已婚已育员工更有责任心。2通知接下来要过苦日子,让一部分不肯同甘共苦的员工自己走人,以“兄弟”和“非兄弟”来区别员工。3强制996。员工如果平衡不了工作和家庭,可在离婚或离职里二选一。4不布置任何工作,但下班前必须提交千字工作日报。5不给活干+...

关于研发效能提升的思考
研发效能提升是最近比较热门的一个话题,本人根据这几年的工作心得,做了一些思考总结,由于个人深度有限,暂且抛转引入。 三要素 任何生产力的提升都离不开这三个因素:人、流程和工具,少了其中任何一个因素都无法实现。 人,即思想,也就是古人说的“道”,道不同不相为谋,是制高点,也是高层建筑的基石。 流程,即方法,也是古人说的“法”。研发效能的提升,也就是要提高投入产出比,既要增加产出,也要减...
