SimpleFormatter忽略java.util.logging.SimpleFormatter.format属性

问题描述

我定义了自己的类来初始化 LogManager

code>通过定义系统属性：
-Djava.util.logging.config.class 。

My class加载 logging.properties 文件，将它与其他一些属性文件合并并进行一些自定义替换。

以下是我的 logging.properties 文件的相关部分：

  java.util.logging.FileHandler.pattern = C：/Work/server/glassfish/domains/domain1/logs/JMSFileHandler%g.log 
 java.util.logging.FileHandler.limit = 2000000 
 java.util.logging.FileHandler.count = 20 
 java.util.logging.FileHandler.append = true 
 java.util.logging.FileHandler.level = ALL 
 java。 util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter 
 java.util.logging.SimpleFormatter.format =％1 $ tY：％1 $ tm：％1 $ td％1 $ tH：％1 $ tM：％1 $ tS |％4 $ s：％2 $ s％n％5 $ s％n％6 $ s％n 
  

我使用标准 FileHandler 并将它配置为使用 SimpleFormatter 作为格式化程序。 / p>

但是 java.util.logging.SimpleFormatter.format 字符串被完全忽略。

$ b

我假定系统属性 java.util.logging.config.file 由GF从一开始就设置。事实并非如此。

经过一番调查后，我意识到 LogManager 被初始化了两次。这是财产第一次不存在，第二次。

我在第一次初始化时收到一个错误，因为我指望这个属性，因此我没有初始化 LogManager ，导致 SimpleFormatter 使用默认格式。

我通过更改代码和不再依赖该系统属性。这解决了这个问题。

GF后来还设置了系统属性 java.util.logging.config.file 。

I'm using java.util.logging on GlassFish 4.

I'm defining my own class to initialize the LogManager by defining the System property: -Djava.util.logging.config.class.

My class loads the logging.properties file, merges it with some other property file and does some custom replacement.

The following is the relevant part of my logging.properties file:

java.util.logging.FileHandler.pattern=C:/Work/server/glassfish/domains/domain1/logs/JMSFileHandler%g.log
java.util.logging.FileHandler.limit=2000000
java.util.logging.FileHandler.count=20
java.util.logging.FileHandler.append=true
java.util.logging.FileHandler.level=ALL
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=%1$tY:%1$tm:%1$td %1$tH:%1$tM:%1$tS|%4$s: %2$s%n%5$s%n%6$s%n

I'm using the standard FileHandler and configuring it to use the SimpleFormatter as the formatter.

But the java.util.logging.SimpleFormatter.format String is being totally ignored. Instead SimpleFormatter uses its default format.

Where did I go wrong?

解决方案

I was assuming that the System Property java.util.logging.config.file is set by GF from the beginning. This is not the case.

After some investigation I realized that the LogManager is initialized two times. In the first time that property doesn't exist, the second time it does.

I was getting an error on the first initialization because I was counting on that property, therefore I didn't initialize the LogManager properly, causing the SimpleFormatter to use the default format.

I fixed this by changing my code and no longer counting on that System property. This solved the issue.

GF still sets the System property java.util.logging.config.file later.
