对于普通的java�E�序包括swt�E�序,我们可以把控制台输出重定向到文本文�g或者界面文本框.

26                 if (line == null) {

30                 }
31             }
32         }
33
34         public boolean isRun() {

39             this.run = run;
40         }

调用:

2             ConsoleThread coThread  = new ConsoleThread();
3             System.setOut(new PrintStream(coThread.getOut(), true));
4             System.setErr(new PrintStream(coThread.getOut(), true));
5             coThread.start();
6         } catch (IOException e) {
7             e.printStackTrace();
8         }

但是有个问题,log4j输出到控制台的信息捕获不�?.......
郁闷
