    具体报错如下，很明显是数据库没有连上导致的错：

    2020-07-01 10:37:37.064 ERROR 58523 --- [           main] com.alibaba.druid.pool.DruidDataSource   : init datasource error, url: jdbc:mysql://localhost:3306/bladex_flow?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&transformedBitIsBoolean=true&serverTimezone=GMT%2B8&nullCatalogMeansCurrent=true&allowPublicKeyRetrieval=true
    com.mysql.cj.jdbc.exceptions.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.

    你需要去排查下数据库连接、账号密码、网段是否联通

    作者追问:2020-07-01 15:36

    image.png 数据库信息我现在修改的是这里的  还需要修改哪个地方的配置么？
