1.通过注解
编写启动类
package cn.bl; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletComponentScan; @SpringBootApplication @ServletComponentScan public class App { public static void main(String[] args) { SpringApplication.run(App.class, args); } } 编写一个监听器
package cn.bl.listener; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; import javax.servlet.annotation.WebListener; @WebListener public class FirstListener implements ServletContextListener{ @Override public void contextInitialized(ServletContextEvent sce) { System.out.println("init .. "); } @Override public void contextDestroyed(ServletContextEvent sce) { System.out.println("desroyed .. "); } } 当执行App的时候
2.通过函数
package cn.bl.listener; import javax.servlet.ServletContextEvent; import javax.servlet.ServletContextListener; public class SecondListener implements ServletContextListener{ @Override public void contextInitialized(ServletContextEvent sce) { System.out.println("second servletListener init .. "); } @Override public void contextDestroyed(ServletContextEvent sce) { System.out.println("second servletListener destroy .. "); } } package cn.bl; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletListenerRegistrationBean; import org.springframework.context.annotation.Bean; import cn.bl.listener.SecondListener; @SpringBootApplication public class App2 { public static void main(String[] args) { SpringApplication.run(App2.class, args); } @Bean public ServletListenerRegistrationBean<SecondListener>getBean(){ ServletListenerRegistrationBean<SecondListener>bean = new ServletListenerRegistrationBean<>(new SecondListener()); return bean; } } 总结
