java - 在名称为 'appServlet' 的 DispatcherServlet 中找不到具有 URI [/myappname/] 的 HTTP 请求的映射

Question

当我在 JBoss 上开始我的项目时，我遇到错误 No mapping found for HTTP request with URI [/myappname/] in DispatcherServlet with name 'appServlet'。这是在解决此处描述的另一个问题后出现的问题:"No Session found for current thread" after changing access method to the session

之前一切正常。我正在使用 Apache Tiles 2。我正在阅读一些类似的问题，但找不到可行的解决方案。

这是我的没有 Hibernate 配置的 DispatcherServlet Context 文件:

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:tx="http://www.springframework.org/schema/tx"

我的 web.xml 整个文件:

<?xml version="1.0" encoding="UTF-8"?>

</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

这是我的IndexController:

@Controller
public class IndexController {

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

此时我的配置有什么问题吗？

我想你不见了<mvc:annotation-driven/>这是阅读 @Controller 所必需的和 @RequestMapping注释。您可以阅读更多关于此的信息 here和 here .
