当我尝试定义数据库设置时出现 java.net.BindException 。这是为什么？

Question

尝试在 openfire 中定义数据库设置时，出现以下错误(正如我在 error.log 文件中看到的那样)

这是openfire数据库设置界面的快照。

我收到此错误的原因可能是什么？

注意:我使用 mysql 作为 xampp 包的一部分

java.net.BindException: Address already in use

该错误通常意味着您尝试打开的端口已被另一个应用程序使用，请尝试使用 netstat 查看哪些端口已打开，然后使用可用端口。

还要检查您是否绑定(bind)到正确的 IP 地址(我假设它是 localhost)
