Question

为什么要记录＆＃34; 1 MAIN INFO＆＃34;当我通过.level = OFF禁用核心库的所有日志记录时，它不起作用。但是对于我的包，我启用了所有日志记录。为什么它只有在我有第二个记录器之后才能用字符串实例化？

LibClass libClass = new LibClass（）;

package com.mycompany;
   public class Main {
      private final static Logger logger = Logger.getLogger(Main.class.getName()); 
      public static void main(String[] args) throws IOException {
          FileInputStream fis = new FileInputStream("log.prop")
          LogManager.getLogManager().readConfiguration(fis);
          logger.info("1 MAIN INFO");
          LibClass libClass = new LibClass();
          libClass.doWork();
          logger.info("3 MAIN INFO");
     }
}

package com.mycompany;
    public class LibClass {
    private final static Logger logger = Logger.getLogger(LibClass.class.getName()); 
    public void doWork() {
        System.out.println("doWork");
        logger.info("2 doWork INFO");
}}


handlers= java.util.logging.ConsoleHandler
.level = OFF
java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
com.mycompany.level = ALL

输出

doWork
[Пт июл 01 22:37:29 EEST 2016] INFO: com.mycompany.LibClass doWork - 2 doWork INFO 
[Пт июл 01 22:37:29 EEST 2016] INFO: com.mycompany.Main main - 3 MAIN INFO

谢谢大家。感谢Andreas的正确答案。

问题在于： Logger.getLogger（Main.class.getName（））在Logger加载配置之前加载类时执行 LogManager.getLogManager（）。readConfiguration（fis）< / em>的

以下是解决方案

package com.mycompany; public class Main { public static void main(String[] args) throws IOException { FileInputStream fis = new FileInputStream("log.prop"); LogManager.getLogManager().readConfiguration(fis); MainClass mainClass = new MainClass(); } } package com.mycompany; public class MainClass { private final static Logger logger = Logger.getLogger(MainClass.class.getName()); public MainClass() throws IOException { logger.info("1 MAIN INFO"); LibClass libClass = new LibClass(); libClass.doWork(); URL url = new URL("http://google.ru");//I don't want see url.openStream(); // fine, finest logs from this code logger.info("3 MAIN INFO"); } } package com.mycompany; public class LibClass { private final static Logger logger = Logger.getLogger(LibClass.class.getName()); public void doWork() { System.out.println("doWork"); logger.info("2 doWork INFO"); } } handlers= java.util.logging.ConsoleHandler .level = OFF java.util.logging.ConsoleHandler.level = ALL java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter com.mycompany.level = ALL

输出

[Сб июл 02 04:32:11 EEST 2016] INFO: com.mycompany.MainClass <init> - 1 MAIN INFO doWork [Сб июл 02 04:32:11 EEST 2016] INFO: com.mycompany.LibClass doWork - 2 doWork INFO [Сб июл 02 04:32:12 EEST 2016] INFO: com.mycompany.MainClass <init> - 3 MAIN INFO

java.util.logging没有正常工作＆＃34; bug或feature＆＃34;
