对Map进行循环
Map<String, String> gameInfo

for (String key : gameInfo.keySet()) {
if (key.equalsIgnoreCase(code)) {
return gameInfo.get(key);
}
}

---------------------------
String[] 转 List
ArrayList<String> codeList = new ArrayList<String>();
int k = codes.length;
if (codes != null) {
for (int i = 0; i < codes.length; i++) {
if (!codes[i].equals("")) {
codeList.add(codes[i]);
}
}
}

mysql 查看进程
show processlist;
kill 3;
