mysql重连，连接丢失：The last packet successfully received from the server

解决方案

数据库连接设置：autoReconnect = true

url=jdbc:mysql://xxx.xxx.xxx.xxx:3306/xxx?characterEncoding=UTF-8&allowMultiQueries=true&autoReconnect=true&pinGlobalTxToPhysicalConnection=true

配置设置：

spring.datasource.druid.testOnBorrow=true

spring.jta.atomikos.datasource.test-query=SELECT 1

spring.jta.atomikos.datasource.borrow-connection-timeout=60
