-stack false|true 关闭对象分配调用栈跟踪(tracking object allocation call stack)。 如果分配位置信息在堆转储中不可用. 则必须将此标志设置为 false. 默认值为 true.> -refs false|true 关闭对象引用跟踪(tracking of references to objects)。 默认值为 true. 默认情况下, 返回的指针是指向其他特定对象的对象...
String s; … t.printStackTrace(pw); s = sw.toString(); sw.getBuffer().setLength(0); …. // 这里的代码省略 } [/code] 这里我们可以看到整体的实现思路。 首先,t.printStackTrace(pw); 获得stack trace字符串。这个t是 new Throwable()的结果。用户程序调用Log4J方法之后,Log4J自己又进行了4次调用...
