你的web.xml配置文件少配置了 org.springframework.web.context.ContextLoaderListener 你的controller类中应该无法注入UserService userService 因为没有配置spring启动 spring和springmvc的BeanFactory的上下文不在一起

No mapping found for HTTP request with URI [/.../...] in DispatcherServlet
在springmvc中，出现No mapping found for HTTP request with URI [/…/…]in DispatcherServlet. 可以从以下几方面排除错误 1.检查@RequestMapping注解的格式 如： <body> <a href="account/finAll">测试</a> </body> 则对应的实体类中的@RequestMapping的属性值必须与超链接的href属性对应。切记在href属性值
