找不到具有基于java配置的URI的HTTP请求的映射

java spring spring-mvc

找不到具有基于java配置的URI的HTTP请求的映射,java,spring,spring-mvc,spring-4,Java,Spring,Spring Mvc,Spring 4,在学习spring时，我试图运行spring的代码示例 但它向我展示了tomcat日志中提到的以下错误： 11-Aug-2016 12:15:57.561 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/RestTester-0.0.1-SNAPSHOT/] in Dispa

在学习spring时，我试图运行spring的代码示例 但它向我展示了tomcat日志中提到的以下错误：

11-Aug-2016 12:15:57.561 WARNING [http-nio-8080-exec-1] org.springframework.web.servlet.PageNotFound.noHandlerFound No mapping found for HTTP request with URI [/RestTester-0.0.1-SNAPSHOT/] in DispatcherServlet with name 'dispatcher'
我试图仅通过基于java的配置来配置spring。 相同的代码如下所述：

请帮助我理解我做错了什么。
Webmvc上的基本包的名称错误，应该是test.controller
您在web.xml文件中编写的内容。。。这应该对你有帮助
