mysql连接分布式数据库异常Could not retrieve transaction read-only status from server

mysql连接分布式数据库异常[Could not retrieve transaction read-only status from server]

---

       一、连接数据库源信息：

jcf.datasource.A.driverClassName=com.mysql.jdbc.Driver

jcf.datasource.A.url=jdbc:mysql://172.21.xx.xxx:8066/bdess_kfdb?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false
jcf.datasource.A.username=bdesskf
jcf.datasource.A.password=bdess

连接参数信息：
jcf.datasource.A.type=com.zaxxer.hikari.HikariDataSource
jcf.datasource.A.default-auto-commit=true
jcf.datasource.A.initial-size=5
jcf.datasource.A.minimum-idle=5
jcf.datasource.A.maximum-pool-size=20
jcf.datasource.A.auto-commit=true
jcf.datasource.A.idle-timeout=30000
jcf.datasource.A.pool-name=DatebookHikariCP
jcf.datasource.A.max-lifetime=1800000
jcf.datasource.A.connection-timeout=30000
jcf.datasource.A.connection-test-query=SELECT 1

 

之前连接的非分布式数据库不存在问题：

jcf.datasource.A.driverClassName=com.mysql.jdbc.Driver
jcf.datasource.A.url=jdbc:mysql://172.21.xx.xx:3307/bdesstj?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false
jcf.datasource.A.username=bdess
jcf.datasource.A.password=bdess

 

二、错误信息

三、问题解决办法

       问题已经解决，程序可以正常启动运行。

       mysql驱动类已经从高版本[mysql-connector-java-5.1.46.jar]降低到低版本[mysql-connector-java-5.1.27.jar ]，可解决程序连接分布式mysql数据异常问题'transaction_read_only'。 mysql驱动部分驱动jar包存在差异。
