如何使用java.util.Logger 打印整个堆栈跟踪?(没有恼人的 Netbeans)。
这个问题最初应该指定留在Java SE 中。忽略该要求是我的错误。

错误代码:
package model;
import java.util.Observable;
import java.util.logging.Logger;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class TelnetEventProcessor extends Observable {
private static Logger log = Logger.getLogger(TelnetEventProcessor.class.getName());
private String string = null;
public TelnetEventProcessor() {
}
private void stripAnsiColors() {
Pattern regex = Pattern.compile("\\e\\[[0-9;]*m");
Matcher regexMatcher = regex.matcher(string);
string = regexMatcher.replaceAll(""); // *3 ??
}
public void parse(String string) {
this.string = string;
ifs();
}
// [\w]+(?=\.)
private void ifs() {
log.fine("checking..");
if (string.contains("confusing the hell out of")) {
Pattern pattern = Pattern.compile("[\\w]+(?=\\.)"); //(\w+)\.
Matcher matcher = pattern.matcher(string);
String enemy = null;
GameData data = null;
while (matcher.find()) {
enemy = matcher.group();
}
try {
data = new GameData.Builder().enemy(enemy).build();
log.fine("new data object\t\t" + data.getEnemy());
setChanged();
notifyObservers(data);
} catch (NullPointerException npe) {
log.severe(npe.printStackTrace(System.out));
}
} else if (string.contains("Enter 3-letter city code:")) {
log.fine("found enter city code");
} else {
}
}
}
