The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.)

根据引用和引用可以看出，连接MySQL数据库失败的原因是通信链路故障。具体错误显示为"The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server."。根据引用中的描述，大部分问题都是修改连接超时的参数，但是修改后并没有解决问题。在查找整体代码时，发现配置文件中MySQL依赖的版本可能不正确。经过将MySQL依赖的版本从6.0.6降低到5.1.47后，问题得以解决，程序成功连接到数据库。提到了另外一种可能性，即将com.mysql.jdbc.Driver替换为com.mysql.cj.jdbc.Driver。这种替换也可能解决连接问题。但是在这个具体例子中，并没有提到进行了此替换。因此，可能原因是引用中的版本更改导致的。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
