自上周以来，我收到了这个奇怪的错误。没有对我的代码进行任何修改，如下所示。
我在SO Answers中遇到了同样的错误，但大多数都提到了xml解析问题，在我的情况下它根本没有。
另一个奇怪的事情是它没有给我堆栈跟踪，请在代码中读出注释以便清晰
private void initializeLoggerContext(Properties properties) throws IOException {
System.out.println("initializeLoggerContext : Properties -> " + properties.toString());
ByteArrayOutputStream output = new ByteArrayOutputStream();
properties.store(output, null);
ByteArrayInputStream input = new ByteArrayInputStream(output.toByteArray());
Configuration conf = null;
try {
ConfigurationSource c = new ConfigurationSource(input);
//conf = PropertiesConfigurationFactory.getInstance().getConfiguration(new ConfigurationSource(input));
ConfigurationFactory conffact = PropertiesConfigurationFactory.getInstance();
System.out.println("ConfigurationFactory conffact = " + conffact.toString());
//ERROR : below line prints message on the console as "[Fatal Error] :1:1: Content is not allowed in prolog." with no stack trace
conf = conffact.getConfiguration(c);
final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
ctx.start(conf);
LOGGER.info("Logging configuration is : {}", ctx);
} catch(Exception e) {//Note getting called when getting "[Fatal Error] :1:1: Content is not allowed in prolog." on the console
System.out.println("initializeLoggerContext : Exception is -> ");
e.printStackTrace();
}
}
我已经使用原始输入属性在下面创建了一个示例应用，但它仍然无法使用log4j 2.5。当我尝试使用带有一个键值对的simple属性时，结果也是相同的。请检查以下代码：

答案 0 :(得分：2)
你试过这个：
PropertiesConfiguration config = new PropertiesConfigurationBuilder().setConfigurationSource(source)
.setRootProperties(properties).build();
Configurator.initialize(config);
这实际上是PropertiesConfigurationFactory的作用： http://logging.apache.org/log4j/2.x/log4j-core/xref/org/apache/logging/log4j/core/config/properties/PropertiesConfigurationFactory.html
考虑到这一点，问题可能是对LoggerContext.start(Configuration)的呼唤。相反，你需要做Configurator.initialize(config)。
