```java
public static synchronized int getAvailablePort(int port) {
if (port < MIN_PORT) {
return MIN_PORT;
}
for (int i = port; i < MAX_PORT; i++) {
if (USED_PORT.get(i)) {
continue;
}
try (ServerSocket ignored = new ServerSocket(i)) {
USED_PORT.set(i);
port = i;
break;
} catch (IOException e) {
// continue
}
}
return port;
}
```
这段代码逻辑你自己写个 demo 跑一下看看 IOException 是不是有东西，可能是环境配置的问题
