使用 JRE 記錄配置檔案

下列範例說明如何在 JRE_DIRECTORY/lib/logging.properties 檔案中設定記錄名稱空間與層級，該檔案將用以設定 Java 執行階段環境的記錄層級。使用此 JRE 的所有應用程式會有相同的記錄配置。以下的配置範例會將 javax.jms.connection 名稱空間的記錄層級設定為 INFO，並指定將輸出寫入 java.util.logging.ConsoleHandler。

#logging.properties file.
# "handlers" specifies a comma separated list of log Handler 
# classes. These handlers will be installed during VM startup.
# Note that these classes must be on the system classpath.
# By default we only configure a ConsoleHandler, which will only
# show messages at the INFO and above levels.

	handlers= java.util.logging.ConsoleHandler

# Default global logging level.
# This specifies which kinds of events are logged across
# all loggers. For any given facility this global level
# can be overriden by a facility-specific level.
# Note that the ConsoleHandler also has a separate level
# setting to limit messages printed to the console.

    .level= INFO

# Limit the messages that are printed on the console to INFO and above.

    java.util.logging.ConsoleHandler.level = INFO
    java.util.logging.ConsoleHandler.formatter = 
                                    java.util.logging.SimpleFormatter

# The logger with javax.jms.connection name space will write
# Level.INFO messages to its output handler(s). In this configuration 
# the ouput handler is set to java.util.logging.ConsoleHandler.

    javax.jms.connection.level = INFO
