Question

我正在尝试使用注释获得简单的spring应用程序，但是在运行应用程序时我遇到异常......

严重：上下文初始化失败 org.springframework.beans.factory.CannotLoadBeanClassException：找不到ServletContext资源中定义名为'viewResolver'的bean的类[org.springframework.web.servlet.view.InternalResourceViewResolver] [/WEB-INF/mvc-dispatcher-servlet.xml ]。嵌套异常是java.lang.ClassNotFoundException：org.springframework.web.servlet.view.InternalResourceViewResolver 在org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass（AbstractBeanFactory.java:1275）在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.predictBeanType（AbstractAutowireCapableBeanFactory.java:575）在org.springframework.beans.factory.support.AbstractBeanFactory.isFactoryBean（AbstractBeanFactory.java:1344）在org.springframework.beans.factory.support.AbstractBeanFactory.isFactoryBean（AbstractBeanFactory.java:910） at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons（DefaultListableBeanFactory.java:609）在org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization（AbstractApplicationContext.java:932）在org.springframework.context.support.AbstractApplicationContext.refresh（AbstractApplicationContext.java:479） at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext（ContextLoader.java:389）在org.springframework.web.context.ContextLoader.initWebApplicationContext（ContextLoader.java:294）在org.springframework.web.context.ContextLoaderListener.contextInitialized（ContextLoaderListener.java:112）在org.apache.catalina.core.StandardContext.listenerStart（StandardContext.java:4779） at org.apache.catalina.core.StandardContext.startInternal（StandardContext.java:5273）在org.apache.catalina.util.LifecycleBase.start（LifecycleBase.java:150）在org.apache.catalina.core.ContainerBase $ StartChild.call（ContainerBase.java:1566）在org.apache.catalina.core.ContainerBase $ StartChild.call（ContainerBase.java:1556） at java.util.concurrent.FutureTask $ Sync.innerRun（Unknown Source） at java.util.concurrent.FutureTask.run（Unknown Source） at java.util.concurrent.ThreadPoolExecutor.runWorker（Unknown Source） at java.util.concurrent.ThreadPoolExecutor $ Worker.run（Unknown Source）在java.lang.Thread.run（未知来源）引起：java.lang.ClassNotFoundException：org.springframework.web.servlet.view.InternalResourceViewResolver 在org.apache.catalina.loader.WebappClassLoader.loadClass（WebappClassLoader.java:1711）在org.apache.catalina.loader.WebappClassLoader.loadClass（WebappClassLoader.java:1556）在org.springframework.util.ClassUtils.forName（ClassUtils.java:260）在org.springframework.beans.factory.support.AbstractBeanDefinition.resolveBeanClass（AbstractBeanDefinition.java:416）在org.springframework.beans.factory.support.AbstractBeanFactory.doResolveBeanClass（AbstractBeanFactory.java:1296）在org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass（AbstractBeanFactory.java:1267） ......还有19个

我的文件是 -

的web.xml

 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <welcome-file>index.jsp</welcome-file>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-                            class>
</listener>

调度-servlet.xml中

       `    <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
  xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd 
           http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<bean
    id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver" >
    <property
        name="prefix"
        value="/WEB-INF/JSP/" />

    <property
        name="suffix"
        value=".jsp" />
</bean>

 <context:component-scan base-package="com.controller" />

`

我在WEB-INF

下的lib文件夹中添加了以下jar

共享记录-1.1.2.jar， org.springframework.aop-3.0.5.RELEASE.jar， org.springframework.asm-3.0.5.RELEASE.jar， org.springframework.aspects-3.0.5.RELEASE.jar， org.springframework.beans-3.0.5.RELEASE.jar， org.springframework.context.support-3.0.5.RELEASE.jar， org.springframework.context-3.0.5.RELEASE.jar， org.springframework.core-3.0.5.RELEASE.jar， org.springframework.expression-3.0.5.RELEASE.jar， org.springframework.transaction-3.0.5.RELEASE.jar， org.springframework.web.servlet-3.0.5.RELEASE.jar， org.springframework.web-3.0.5.RELEASE.jar

我不确定为什么会这样，所以请帮助我。

我通过从服务器中删除其他项目来修复此问题

Answer 1

将spring-webmvc jar添加到classpath

Answer 2

只需更改spring框架的版本即可。使用版本4.1.5.RELEASE jar

无法为bean找到类[org.springframework.web.servlet.view.InternalResourceViewResolver]
