为特定程序包设置Java Logger [英] Setting up java Logger for a specific package

问题描述

有人可以向我解释一下，如何从一个具体的包中为各种类设置Java Logger吗?

could anybody explain to me, how to set up java Logger for various classes from a concrete package ?

例如: 如果我得到了它并进行设置

for example: if I get this one and set it up

Logger logger = Logger.getLogger("com.google.api.client.*");
        logger.setLevel(Level.CONFIG);
        logger.addHandler(new Handler() {

            @Override
            public void close() throws SecurityException {
            }

            @Override
            public void flush() {
            }

            @Override
            public void publish(LogRecord record) {
                // default ConsoleHandler will take care of >= INFO
                if (record.getLevel().intValue() < Level.INFO.intValue()) {
                    System.out.println(record.getMessage());
                }
            }
        });

有这样的条件

Logger.getLogger(HttpTransport.class.getName()).isLoggable(Level.CONFIG);

在库中，HttpTransport是com.google.api.client.*的一部分

但是问题是，

Logger.getLogger(HttpTransport.class.getName()).isLoggable(Level.CONFIG); 

是false ...就像是否获得了其他记录器一样

is false ... like if a different logger was obtained

我还应该如何为同一包中的所有类设置它?是否有条件让记录器使用HttpTransport之类的具体类.

How else should I set it for all classes from the same package? if there are conditions for loggers for concrete classes like HttpTransport.

推荐答案

您不希望包字符串中带有.*. 更改

You do not want the .* in your package string. Change

Logger logger = Logger.getLogger("com.google.api.client.*");

到

Logger logger = Logger.getLogger("com.google.api.client");
