我的 tomcat/conf 目录中有一个通用的 logging.properties ..

如何修改它以能够处理(使用 java 类)我的应用程序生成的所有日志?

有没有办法在不使用包装器(来自 Log API)类的情况下做到这一点?

您可以使用Handler子类来处理正在记录的数据。

然后,您可以通过配置文件或通过addHandlerLogger 类的方法以编程方式将其添加到您的根记录器。

例如,您可以创建一个 Handler 子类 FoobarHandler ,它在控制台上打印所有记录的数据,前缀为“Foobar”文本:

public class MyHandler extends Handler {

    @Override
    public void close() throws SecurityException {
        // housekeeping before handler close
    }

    @Override
    public void flush() {
        // not really needed as data is processed without any sort of buffering
    }

    @Override
    public void publish(LogRecord record) {
        System.out.println("Foobar " + record.getMessage().toUpperCase());
    }

}

myapp.FoobarHandler在您的配置文件中,您将 Handler的类名(即)添加到全局处理程序配置中:

# 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
