java - 添加自定义记录器时出现 Glassfish TimeoutException

标签 java logging glassfish glassfish-4

编辑:我的自定义处理程序中有一个静态初始化程序 block 。当我删除它时，它运行良好。我怀疑静态初始化程序有问题。它尝试访问一些系统属性和一些 LogManager 属性。

我正在从 Eclipse Kepler 运行 GlassFish。

我正在将自己的自定义记录器添加到 GlassFish 4，如 Administration guide 第 7 章中所述。

我所做的就是将新的处理程序 jar 放入 domain-dir/lib/ext 目录中，并在 logging.properties 文件中引用它，如下所示:

handlers=java.util.logging.ConsoleHandler,com.mytools.logging.JMSFileHandler

但是当我启动 GlassFish 时，它卡在 69% 处，过了一会儿我收到超时错误:

最佳答案

经过大量的试验和错误，我发现问题出在我的处理程序类的静态初始化程序中。

有两个部分会卡住 GlassFish 并导致 TimeoutException:

1。访问日志管理器:

LogManager logManager = LogManager.getLogManager();

2。尝试从我的包中读取资源。

请记住，Jar 文件将放置在 domain-dir/lib/ext 目录中:

    Properties logProperties = new Properties();
    try (InputStream packageStream = JMSFileHandler.class.getResourceAsStream("JMSFileHandler.properties")) {
        if (packageStream != null) {
            logProperties.load(packageStream); //this line causes freeze
        }
    } catch (IOException e) {
        e.printStackTrace();
    }

这里的关键行是标有//this line Causes freeze的行。因此，它只是尝试加载导致问题的属性。
