Question

在我的应用程序中，我想使用Spring Scheduler安排邮件，下面是我的代码。

应用context.xml中

启动tomcat服务器时，我给出了以下错误。

我没有在bean中配置RequestMapping然后我收到此错误。

Answer 1

请将您的Quartz jar文件替换为最新版本的quartz-2.2.1

Answer 2

您错过了类路径中的quartz.jar。添加它，错误应该消失。

创建名为'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping的bean时出错
