Every time you write a new class, you must declare it as follows:
private static Logger logger = Logger.getLogger(Test.class);
Isn’t this very troublesome? Is there any way to set the Logger to a class that can be called statically, directly call the info, error and other methods, and at the same time print out the current class, thread number and other information?

You can simply encapsulate it to achieve what you want, such as building a class to encapsulate Logger and exposing several static interfaces. As for why many codes are written as private static Logger logger = Logger.getLogger(Test.class);, it is actually mainly to improve the flexibility and accuracy of logs.

If your logs are processed in the same way, you can declare it公共的靜態(tài) log 對(duì)象, 需要的地方使用該logThere will be no duplicate declarations.
For example:
import static xxx.GlobalLogs.log;
log.debug("...");
log.info("...");
//...Of course you can also use lombok to simplify your code.
