這是webxml中的配置 <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:application-context.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>example</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>example</servlet-name> <url-pattern>/api/*</url-pattern> </servlet-mapping> 如何通過controller中獲取bean，如果使用ClassPathApplicationContext獲取會報錯，請問該怎么辦??？各位大哥誰能幫一下啊
