Implement Custom Logger with slf4j
提问by Martin Dürrmeier
I want to implement a Custom logger which logs all log entries to a Database. Currently my app logs this way (slf4j and log4j binding):
我想实现一个自定义记录器，它将所有日志条目记录到数据库中。目前我的应用程序以这种方式记录（slf4j 和 log4j 绑定）：
private static final Logger logger = LoggerFactory.getLogger( MyClass.class );
I'm not sure how to proceed. My Idea is to implement a Custom Logging binding through implementing the org.slf4j.Logger Interface
我不知道如何继续。我的想法是通过实现org.slf4j.Logger 接口来实现自定义日志绑定
What would be the next steps? My target is to not change the current code
接下来的步骤是什么？我的目标是不更改当前代码

it should be fairly easy. you'll need to implement your own Loggerand LoggerFactory. you will not have to change existing code at all.
这应该相当容易。您需要实现自己的Logger和LoggerFactory. 您根本不必更改现有代码。
after doing that you'll need to implement StaticLoggerBinderto return your logger factory and class name. if you download the slf4j zip file then you get the source for all the implementations too, just have a look at the StaticLoggerBinder in slf4j-log4j for an example.
这样做之后，您需要实现StaticLoggerBinder以返回您的记录器工厂和类名。如果您下载 slf4j zip 文件，那么您也可以获得所有实现的源代码，只需查看 slf4j-log4j 中的 StaticLoggerBinder 为例。

You do not have to write your own logging implementation, how about switching the logging framework to logback? Loback supports logging to database natively. As you use the SLF4J API both times your code won't change.
您不必编写自己的日志记录实现，那么将日志记录框架切换到logback怎么样？Loback 支持本地记录到数据库。当您两次使用 SLF4J API 时，您的代码都不会改变。
Take a look at the ch.qos.logback.classic.db.DBAppender. If the default table layout does not fit your needs, you can implement ch.qos.logback.classic.db.names.DBNameResolverto customzie the table and coloum names.
看看ch.qos.logback.classic.db.DBAppender。如果默认的表格布局不符合您的需求，您可以实现ch.qos.logback.classic.db.names.DBNameResolver来自定义表格和列名。
