2.启动类

package cn.khue.practice;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

/**
 * @author khue
 * @description 启动类
 * @date 2020-11-05
 * */
@SpringBootApplication
@ServletComponentScan
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }
}

3.自定义过滤器

import javax.servlet.annotation.WebListener;
import javax.servlet.http.HttpSessionAttributeListener;
import javax.servlet.http.HttpSessionBindingEvent;

import javax.servlet.http.HttpSessionListener;
