实际开发中,记录日志是常用的功能,jboss默认情况下已经记录了很多运行日志,如果开发人员要手动在server.log中写入日志,可以参考下面的方法:
1 package utils;
2
3 import java.util.logging.Level;
4 import java.util.logging.Logger;
5
6 public final class LoggerUtils {
7
8 private final static Logger LOGGER = Logger.getLogger(LoggerUtils.class
9 .toString());
10
11 public static void info(String msg) {
12 LOGGER.info(msg);
13 System.out.println(msg);
14 }
15
16 public static void severe(String msg) {
17 LOGGER.log(Level.SEVERE, msg);
18 System.out.println(msg);
19 }
20
21 }
有了这个类后,其它地方就可以方便使用了,比如在web应用中,可以在ManagedBean上直接用:
1 package controller;
2
3 import javax.inject.Named;
4 import utils.LoggerUtils;
5
6 @Named("Index")
7 public class IndexController {
8
9 public String sayHello() {
10 String msg = "hello ,this is a log message for test";
11 LoggerUtils.info(msg);
12 LoggerUtils.severe(msg);
13
14 return "Hello Logeer!";
15
16 }
17
18 }
随便建个xhtml页面调用一下:
<b>#{Index.sayHello()}</b>
最后运行效果如下:
