問題:java.lang.ClassNotFoundException: org.springframework.web.servlet.mvc.support.ControllerClassN

問題:java.lang.ClassNotFoundException: org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping-2020-6-23
原因: 可能版本問題
解決: 可以用org.springframework.web.servlet.handler.SimpleUrlHandlerMapping，代替

例如
之前

 <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />

之後

 <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
      <property name="mappings">
         <props>
            <prop key="/welcome.htm">welcomeController</prop>           
            <prop key="/helloWorld.htm">helloController</prop>
         </props>
      </property>
   </bean>

   <bean id="helloController" class="com.tutorialspoint.HelloController" />

   <bean id="welcomeController" class="com.tutorialspoint.WelcomeController"/>
