java - 记录器(log4j)应该在 servlet 中的哪里初始化？

Question

我正在 servlet 的构造函数中初始化记录器。这是一个好的做法吗？我应该在 servletContextListener 中初始化它吗？

示例代码:

public class MyService{
Logger logger;

 public MyService(){
   logger = Logger.getLogger(MyService.class);
 }

}

Answer 1

Use the logger as a Class level member by declaring it as static

Initialize it properly

Little How-to

private static final Logger logger = Logger.getLogger(*<yourclass>*.class)
