Set keyset = System.getProperties().keySet();
for(Iterator itr = keyset.iterator(); itr.hasNext();){
String key = (String)itr.next();
String val = System.getProperty(key);
logger.warn("----------->" + key + "<===========>" + val);
}

测试用代码

import java.util.Iterator;
import java.util.Set;
public class showcurr {
public static void main(String arg[]) {
Set keyset = System.getProperties().keySet();
for(Iterator itr = keyset.iterator(); itr.hasNext();){
String key = (String)itr.next();
String val = System.getProperty(key);
System.out.println("----------->" + key + "<===========>" + val);
}
}
