如何配置logging.properties将内容放入Java类（没有包装器模式）？

我在tomcat/conf目录中有一个公共logging.properties

我如何修改它以处理（使用java类）应用程序生成的所有日志

如果不使用包装器（来自Log API）类，有什么方法可以做到这一点吗？

您可以使用子类来处理记录的数据

然后，您可以通过配置文件或通过logger类的

addHandler

方法将其添加到根记录器中

例如，您可以创建一个处理程序子类FoobarHandler，用于在控制台上打印所有以“Foobar”文本为前缀的记录数据：

在配置文件中，将处理程序的类名（即

myapp.FoobarHandler

）添加到全局处理程序配置：

# Global logging properties.
# ------------------------------------------
# The set of handlers to be loaded upon startup.
# Comma-separated list of class names.
# (? LogManager docs say no comma here, but JDK example has comma.)
handlers=java.util.logging.FileHandler, myapp.FoobarHandler

# Default global logging level.
# Loggers and Handlers may override this level
.level=INFO

# Loggers
# ------------------------------------------
# Loggers are usually attached to packages.
# Here, the level for each package is specified.
# The global level is used by default, so levels
# specified here simply act as an override.
myapp.ui.level=ALL
myapp.business.level=CONFIG
myapp.data.level=SEVERE

你能举个例子吗？

handlers=java.util.logging.FileHandler, myapp.FoobarHandler

# Default global logging level.
