问题描述

I am using spring 4.0.4 RELEASE.jar but i got class not found exception. 我正在使用spring 4.0.4 RELEASE.jar但我没有找到类异常。 Here is my web.xml 这是我的web.xml 

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

<servlet>
   <servlet-name>spring-dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.Dispatcherservlet</servlet-class>
 </servlet>
   <servlet-mapping>
 <servlet-name>spring-dispatcher</servlet-name>
   <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

Here is my spring-dispatcher-servlet.xml code 这是我的spring-dispatcher-servlet.xml代码 

<beans xmlns="http://www.springframework.org/schema/beans"

   <bean id= "viewResolver"

           <property name="prefix" value="/WEB-INF/" />
       <property name="suffix" value=".jsp" />
    </bean>
 </beans>

2 个解决方案

Notice the error message: 注意错误消息： 

Error instantiating servlet class org.springframework.web.servlet.Dispatcherservlet
                                                                            ^

and later in the stack trace: 然后在堆栈跟踪中： 

java.lang.ClassNotFoundException: org.springframework.web.servlet.Dispatcherservlet

The correct spelling is DispatcherServlet with uppercase S . 正确的拼写是DispatcherServlet带有大写S

Long term solution 长期解决方案

While using Spring 4.X and above, it is always recommended to use Bill of Materials provided by them. 使用Spring 4.X及更高版本时，始终建议使用它们提供的材料明细表。 It pull out the relevant dependencies and helps in avoiding all kind of build path/runtime errors caused by your application. 它提取了相关的依赖项，并有助于避免由应用程序引起的所有类型的构建路径/运行时错误。

In your case, please add these dependencies in your POM.xml file or the above bill of materials provided by them (choice is yours) 对于您的情况，请在您的POM.xml文件或它们提供的上述材料清单中添加这些依赖项（选择由您自己决定）
