我用手动配置是可以正常运行的,(实现Controller类)
这个是Controller代码
@Controller //扫描到Spring容器
public class HelloController {
@RequestMapping("/hello")
public ModelAndView execute(){
ModelAndView mav = new ModelAndView();
mav.setViewName("hello");
mav.getModel().put("msg", "helloSpringMVC(注解版)");
return mav;
}
}
这个是Applicationcontext.xml代码
<!-- 配置mvc注解扫描(新版本) -->
<mvc:annotation-driven/>
<!-- 扫描controller -->
<context:component-scan base-package="org.yzl.controller"/>
<!-- <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> -->
<!-- <property name="mappings"> -->
<!-- <props> -->
<!-- <prop key="/hello.do" >helloController</prop> -->
<!-- </props> -->
<!-- </property> -->
<!-- </bean> -->
<!-- <bean id="helloController" class="org.yzl.controller.Hello"></bean> -->
<!-- 配置viewResolver -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
下面是启动tomcat报错的代码
