抛出这样的异常怎么解决啊？Cannot find class [org.springframework.web.servlet.handler.

[jsp_rookie]

这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--初始化参数-->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/dispatcherServlet-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!--拦截所有以do结尾的请求-->
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>

以下是我的dispatcherServlet-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/ dtd/spring-beans.dtd">
<beans>
<!--定义映射-->
<bean id="urlMapping"
class="org.springframework.web.servlet.handler.
SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="helloWorld.do">helloWorldController</prop>
</props>
</property>
</bean>
<!--定义视图-->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass">
<value>org.springframework.web.servlet.view.InternalResourceView</value>
</property>
</bean>
<!--定义控制器-->
<bean id="helloWorldController" class="HelloWorldController">
<property name="helloWorld">
<value>HelloWorld</value>
</property>
<property name="viewPage">
<value>/jsp/helloWorld.jsp</value>
</property>
</bean>
</beans>

在\WEB-INF\classes下已经生成了HelloWorldController.class
但还是抛出异常

[代码间的舞者]

class="org.springframework.web.servlet.handler. SimpleUrlHandlerMapping"> 如果没看错的话handler. 和SimpleUrlHandlerMapping之间多了一个空格，你把空格去掉试试。

Cannot find class [org.springframework.web.servlet.handler. SimpleUrlHandlerMapping] for bean with name 'urlMapping' defined in ServletContext resource [/WEB-INF/dispatcherServlet-servlet.xml] 这个异常的意思是在你的xml配置文件里面对应的org.springframework.web.servlet.handler. SimpleUrlHandlerMapping类没有找到。很明显，提示说的这个类，中间空了很多空格。 你把下面的这个配置写到一行之后，再启动试试，应该就可以了。 <!--定义映射--> <bean id="urlMapping" class="org.springframework.web.servlet.handler. SimpleUrlHandlerMapping">

我使用的是tomcat6.0+ java 1.6

[人生重来]

这个类没有找到org.springframework.web.servlet.handler. SimpleUrlHandlerMapping

引用 2 楼 wo99128608 的回复:
