我在spring-boot(1.5.3.RELEASE)应用程序中使用AsyncAppender.

logback.xml

<appender name="FILE_ASYNC" class="ch.qos.logback.classic.AsyncAppender">
    <queueSize>5000</queueSize>
    <discardingThreshold>0</discardingThreshold>
    <appender-ref ref="FILE" />
</appender>

根据logback文档,

在应用程序关闭或重新部署时,必须停止AsyncAppender才能停止并回收工作线程并从队列中清除日志记录事件.

https://logback.qos.ch/manual/appenders.html

进一步说:

为了避免在这些条件下中断工作线程,可以在JVM运行时插入关闭挂钩,以便在启动JVM关闭后正确停止LoggerContext

我想知道如何在Spring Boot应用程序中停止AsyncAppender.在Spring Boot中的哪个位置,我应该定义shutdown hook吗？

在Java项目中,我使用的是Sprig Boot 1.5.3.RELEASE.它连接两个数据库,即MongoDB和Microsoft SQLServer.当我用spring-boot运行它:运行目标时,它运行正常.但是,当我尝试使用包目标运行它时,测试用例会报告以下错误,尽管这些测试用例未连接到SQL Server数据库:

我使用以下过滤器来控制使用GlassFish作为应用程序服务器访问JSF 2.0中的所有页面.问题是,使用此代码虽然过滤器工作正常,如果用户尝试直接访问任何其他页面,但用户将重定向到log.xhtml但是login.xhtml看起来不太好(没有显示彩色图像,而页面形状发生变化),因为它应该是.但是,如果我删除sendRedirect语句并将其替换为chain.doFilter语句,那么页面显示方式应该看起来不错,但是过滤效果不明显.我该如何解决这个问题？

LoggingFilter.java

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException {   
    HttpServletRequest req = (HttpServletRequest) request;
    LoginBean auth = (LoginBean) req.getSession().getAttribute("loginBean");




    if ((auth != null && auth.isLoggedIn()) || req.getRequestURI().endsWith("/login.xhtml")) {
        // User is logged in, so just continue request.
        HttpServletResponse httpResponse = (HttpServletResponse)response;
        httpResponse.setHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
        httpResponse.setHeader("Pragma", "no-cache"); // HTTP 1.0.
        httpResponse.setDateHeader("Expires", 0); // Proxies.
        chain.doFilter(request, response);
    } else {
