java - 如何使用 Eclipse Juno 从管理系统连接 MYSQL 数据库？

Question

我尝试在服务器和客户端系统之间创建 Mysql 连接。我的管理系统 IP 地址是(192.168.1.5)。我有一个数据库“测试”。我下载了 mysql-connector-java-5.1.29 并添加了 Java Buildpath。截图如下:

每当我尝试测试连接时，它都会显示这样的错误..

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException:通信链路故障

最后一次成功发送到服务器的数据包是在 0 毫秒前。驱动程序尚未收到来自服务器的任何数据包。
