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


   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="prefix" value="/WEB-INF/views/"></property>
       <property name="suffix" value=".jsp"></property>
   </bean>

</beans>

hello.java

package com.feiniu.test;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloWord {
   @RequestMapping("/helloword")
public String hello(){
       /**
       * /WEB-INF/views+"success" +".jsp" =WEB-INF/views/success.jsp
       */
   System.out.println("hellword");
   return "success";
}
}

在/WEB-INF下面创建views文件夹并创建success.jsp
