主要内容
整合Listener
一、整合Listener
1.1 编写Listener
通过注解扫描完成Filter组件的注册
/**
* springboot整合listener方式一
*
* 之前的配置方式
* <listener>
* <listener-class>com.ls.springboot.listener.FirstListener</listener-class>
* </listener>
*/
@WebListener
public class FirstListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
System.out.println("Listener ... init ....");
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
1.2 编写SpringBoot启动类
/**
* springboot整合Listener方式一
*/
@SpringBootApplication
@ServletComponentScan
public class App {
public static void main(String [] args){
SpringApplication.run(App.class,args);
}
}
二、通过完成Filter组件的祖册
2.1 编写Filter
/**
* SpringBoot整合Listener方式二
*/
public class SecondListener implements ServletContextListener {
@Override
public void contextInitialized(ServletContextEvent sce) {
System.out.println("SecondLister...init...");
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}
2.1 编写springboot启动类
@SpringBootApplication
public class App2 {
public static void main(String [] args){
SpringApplication.run(App2.class,args);
}
/**
* 注册listener
*/
@Bean
public ServletListenerRegistrationBean<SecondListener> getServletListenerRegistrationBean(){
ServletListenerRegistrationBean<SecondListener> bean = new ServletListenerRegistrationBean<SecondListener>(new SecondListener());
return bean;
}
}
