正在学习本网站的秒杀课程,按照老师的步骤搭建框架但运行时eclipse抛出异常。经过检查配置文件的拼写都没有问题(为了防止此问题从网上找了源码的配置文件又复制了一遍),maven依赖都已引入而且单元测试和集成测试都通过了就是运行tomcat后访问网站时报错,已经整了好长时间了请有经验的人指点。 严重: Allocate exception for servlet seckill-dispatcher java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1333) at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1167) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:520) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:501) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:120) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1095) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:817) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:135) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:106) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:142) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:79) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:616) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:88) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:518) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1091) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:673) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1500) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1456) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Thread.java:745) web.xml配置代码 <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" metadata-complete="true"> <!--配置DispatcherServlet--> <servlet> <servlet-name>seckill-dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--配置SpringMVC需要加载的配置文件 spring-dao.xml spring-service.xml spring-web.xml Mybatis -> spring -> springMVC --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-*.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>seckill-dispatcher</servlet-name> <!--默认匹配所有请求--> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> spring-web.xml配置文件 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 配置springMVC --> <!-- 1:开启springMVC注解模式--> <!-- 简化配置: (1)自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter (2)提供一系列:数据绑定,数字和日期的formet @NumberFormat,@DataTimeFormat,xml,json默认读写支持 --> <mvc:annotation-driven/> <!--2:静态资源默认servlet配置 (1)加入对静态资源的处理:js,gif,png (2)允许使用"/"做整体映射 --> <mvc:default-servlet-handler/> <!--3:配置JSP 显示ViewResolver--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> </bean> <!--4:扫描web相关的bean--> <context:component-scan base-package="org.seckill.web"/> </beans>
