Java 应用程序启动index.jsp而不是mail-menu.jsp

我的演示应用程序有问题。 为什么应用程序启动index.jsp不是我在HomeController中映射的main-menu.jsp？正如我通过调试器看到的，没有使用HomeController。 问题出在哪里？如何解决？ 谢谢

我不太确定问题出在哪里，但我所能做的就是向你建议一些替代方案。尝试将控制器配置为：

public class HomeController extends AbstractController{

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request,
        HttpServletResponse response) throws Exception {

        ModelAndView model = new ModelAndView("main-menu");
        model.addObject("msg", "Lets Check");

        return model;
    }
}

Web.xml：

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>spring-mvc-demo</servlet-name>
        <url-pattern>/</url-pattern>
  </servlet-mapping>

您的spring mc demo servlet.xml如下所示：

<bean name="/welcome.htm" 
        class="com.aalegz.springdemo.mvc,HomeController" />

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

/WEB-INF/pages/
.jsp

你看，我已经提到了它作为一种替代方案，所以如果答案对你没有帮助，请不要投反对票，我已经努力寻找解决方案。

*.htm

可能会让别人投你的反对票哦，对不起，url是否只映射到“/”ok@勒库姆

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>
