这是我的web.xml

     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     version="2.5">

<servlet>
    <servlet-name>spring-web</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <!-- 
   <init-param>
           <param-name>contextConfigLocation</param-name>
           <param-value>/WEB-INF/spring-mvc-config.xml</param-value>
   </init-param>
    -->
</servlet>
<servlet-mapping>
    <servlet-name>spring-web</servlet-name>
    <url-pattern>/index</url-pattern>
</servlet-mapping>
<welcome-file-list>
    <welcome-file>/index</welcome-file>
</welcome-file-list>

这是我的控制器

@Controller
@Transactional
public class HelloController {

    @Autowired(required = true)
    private SessionFactory sf;

    @RequestMapping(value = "/index", method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {
        return "index";
    }
}

所以，当我开始我的程序时，它会将我发送到我已经形成的index.html，并可以继续使用它。

Answer 1

可能是因为您在spring组件中使用了不同的版本，尝试使用所有Spring依赖项的相同版本

Answer 2

好的，老实说，我不知道问题是什么，但重新启动IDE和Clean Build可以帮助我处理它。
