javaee实现在spring执行后执行相关代码
1:首先在web.xml中声明servlet
<servlet> <servlet-name>ApplicationOnload</servlet-name> <servlet-class>com.ApplicationOnload</servlet-class> </servlet> <servlet-mapping> <servlet-name>ApplicationOnload</servlet-name> <url-pattern>/ApplicationOnload</url-pattern> </servlet-mapping>
2:在ApplicationOnload中继承ContextLoaderListener
import java.util.ArrayList; import java.util.List; import javax.servlet.ServletContextEvent; import org.springframework.context.ApplicationContext; import org.springframework.web.context.ContextLoaderListener; import org.springframework.web.context.support.WebApplicationContextUtils; public class ApplicationOnload extends ContextLoaderListener { private DisplayService displayService; public void contextInitialized(ServletContextEvent event) { ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext(event.getServletContext()); displayService = (DisplayService)applicationContext.getBean("displayService"); <span style="white-space:pre"> </span>//相关代码 } }
