nutz 的事物Trans.begin 不检查连接池的连接， 需要自己检查吗？


static void _begain(int level) throws Exception {
Transaction tn = trans.get();
if (null == tn) {
tn = null == implClass ? new NutTransaction() : Mirror.me(implClass).born();
tn.setLevel(level);
trans.set(tn);
count.set(0);
if (DEBUG)
log.debugf("Start New Transaction id=%d, level=%d", tn.getId(), level);
} else {
if (DEBUG)
log.debugf("Attach Transaction id=%d, level=%d", tn.getId(), level);
}
int tCount = count.get() + 1;
count.set(tCount);
//if (DEBUG)
// log.debugf("trans_begain: %d", tCount);
