通信链路故障

每天固定的时间就会在日志里面反馈出来，不知道是mysql的配置问题还是druid的配置问题，还是druid的版本问题 我用的是druid-starter 版本是 1.1.18 druid的版本号是 1.1.18(很奇怪，错误代码里面指明的是1.1.17) mysql的版本是5.7.20 mysql-connector-java的版本是5.1.40 1.日志报错截图：（我们用了mycat做数据库中间件）

2.druid的​配置： #datasource spring.datasource.driver-class-name = com.mysql.jdbc.Driver spring.datasource.druid.filter.stat.enabled = true spring.datasource.druid.filter.stat.log-slow-sql = true spring.datasource.druid.filter.stat.merge-sql = true spring.datasource.druid.filter.stat.slow-sql-millis = 1000 spring.datasource.druid.filters = stat,wall,log4j spring.datasource.druid.keep-alive = true spring.datasource.druid.remove-abandoned = true spring.datasource.druid.remove-abandoned-timeout = 1800 spring.datasource.druid.initialSize = 5 spring.datasource.druid.maxActive = 30 spring.datasource.druid.maxWait = 60000 spring.datasource.druid.minEvictableIdleTimeMillis = 300000 spring.datasource.druid.timeBetweenEvictionRunsMillis = 60001 spring.datasource.druid.minIdle = 5 spring.datasource.druid.stat-view-servlet.enabled = true spring.datasource.druid.stat-view-servlet.login-username = tezign spring.datasource.druid.stat-view-servlet.login-password = tezign0818 spring.datasource.druid.testOnBorrow = false spring.datasource.druid.testOnReturn = false spring.datasource.druid.testWhileIdle = true spring.datasource.druid.useGlobalDataSourceStat = true spring.datasource.druid.validationQuery = SELECT 1 FROM DUAL spring.datasource.druid.validationQueryTimeout = 10 spring.datasource.druid.web-stat-filter.enabled = true spring.datasource.type = com.alibaba.druid.pool.DruidDataSource

#mysql spring.datasource.druid.my-cat.url = jdbc:mysql://mycat:xxxx/xx?useUnicode=true&characterEncoding=utf8&autoReconnect=true&zeroDateTimeBehavior=convertToNull&allowMultiQueries=true spring.datasource.druid.my-cat.username = xxxx spring.datasource.druid.my-cat.password = xxxx

3.mysql的关键配置

wait_timeout, 86400 connect_timeout, 10 interactive_timeout, 7200
