Question

我正在使用ServletRequestListener进行实验。我运行程序时得到以下输出。一些请求在初始化之前被销毁。那是为什么？

New request arrived to server :/projeDB/
Request destroyed : /projeDB/javax.faces.resource/primefaces.css.xhtml;jsessionid=2CDF29CD90D3EB1143D06AACAF7BA387
Request destroyed : /projeDB/javax.faces.resource/jquery/jquery.js.xhtml;jsessionid=2CDF29CD90D3EB1143D06AACAF7BA387

我的ServletRequestListener：

public class RequestListener implements ServletRequestListener {
    @Override
    public void requestDestroyed(ServletRequestEvent sre) {
        System.out.println("New request arrived to server :" + ((HttpServletRequest) sre.getServletRequest()).getRequestURI())  ; 
    }

    @Override
    public void requestInitialized(ServletRequestEvent sre) {
        System.out.println("Request destroyed : " + ((HttpServletRequest) sre.getServletRequest()).getRequestURI());
    }
}

您是否在方法中切换了打印语句？您打印请求已在requestInitialized()方法中销毁，反之亦然。

请求在初始化之前销毁
