添加SSL配置后log4j不能与Jetty一起工作

Question

我试图使用SSL运行一个Jetty(v9)服务器（这样访问只能通过HTTPS进行）。使用普通HTTP时，一切都运行良好。然后我更改了我的launcher类，所以它看起来如下所示：

PropertyConfigurator.configure("war/WEB-INF/log4j.properties");
Server server = new Server();

WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setWar("war");
server.setHandler(webapp);

HttpConfiguration https = new HttpConfiguration();
https.addCustomizer(new SecureRequestCustomizer());

SslContextFactory sslContextFactory = new SslContextFactory();
sslContextFactory.setKeyStorePath("keystore.jks");
sslContextFactory.setKeyStorePassword("<password>");
sslContextFactory.setKeyManagerPassword("<password>");

ServerConnector sslConnector = new ServerConnector(server,
        new SslConnectionFactory(sslContextFactory, "http/1.1"),
        new HttpConnectionFactory(https));
sslConnector.setPort(443);
server.setConnectors(new Connector[] { sslConnector });

LOG.info("Starting server on port 443");
server.start();
server.join();

我还运行这个来生成一个密钥库文件：

keytool -genkey -alias sitename -keyalg RSA -keystore keystore.jks -keysize 2048

log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
log4j:ERROR The class "org.apache.log4j.Appender" was loaded by 
log4j:ERROR [sun.misc.Launcher$AppClassLoader@178b0f9] whereas object of type 
log4j:ERROR "org.apache.log4j.RollingFileAppender" was loaded by [WebAppClassLoader=8317419@7ee9eb].
log4j:ERROR Could not instantiate appender named "filer".
log4j:WARN No appenders could be found for logger (ie.search4less.quickbooks.servlet.AppServlet).

static {
    PropertyConfigurator.configure("war/WEB-INF/log4j.properties");
}

log4j.rootLogger=INFO, filer

log4j.appender.filer=org.apache.log4j.RollingFileAppender
log4j.appender.filer.layout=org.apache.log4j.PatternLayout
log4j.appender.filer.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-4r [%t] %-5p %c %x - %m%n
log4j.appender.filer.File=./logs/quickbooks.log
log4j.appender.filer.MaxFileSize=1MB
log4j.appender.filer.MaxBackupIndex=9
log4j.appender.filer.append=true

正如我所说的，在我将新的SSL配置代码添加到服务器启动器类之前，一切都很好，但我不明白哪里出了问题。

Answer 1

我让它起作用了。这个问题实际上与SSL配置无关。在添加这些SSL配置更改之间，我将lib目录移动到WEB-INF中，其中包含了我的所有依赖项（包括log4j和slf4j jar）。这引起了某种冲突。把他们从那里移走就解决了。
