springboot项目页面地址url出现的jsessionId

在启动类中继承SpringBootServletInitializer，然后重写这个方法

@SpringBootApplication
public class NewscreeningApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(NewscreeningApplication.class, args);
    }
    //去掉url带的jsessionid
    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.setSessionTrackingModes(Collections.singleton(SessionTrackingMode.COOKIE));
        SessionCookieConfig sessionCookieConfig=servletContext.getSessionCookieConfig();
        sessionCookieConfig.setHttpOnly(true);
    }

}
