我從github上拉取的項(xiàng)目，無(wú)法連接數(shù)據(jù)庫(kù)，我看項(xiàng)目配置的數(shù)據(jù)庫(kù)連接是localhost的，那么我是要自己在本地創(chuàng)建數(shù)據(jù)庫(kù)嗎，如果這樣的話那數(shù)據(jù)庫(kù)里面的表信息在哪里啊，第一次用github拉項(xiàng)目，萌新求教

部分錯(cuò)誤信息

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

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

拉的項(xiàng)目的數(shù)據(jù)庫(kù)配置
