How does the java code think that sql executes in which database? The solution to the viewing idea of the local server and the server.

problem description

Local read-write separation uses spring"s aop, which has only one library locally and multiple libraries online.

the environmental background of the problems and what methods you have tried

there is no problem with the local update. When you report an error online, the update error message is as follows:
org.springframework.jdbc.UncategorizedSQLException:-sharp-sharp-sharp Error updating database. Cause: java.sql.SQLException: The MySQL server is running with the-- read-only option so it cannot execute this statement-sharp-sharp-sharp The error may involve com.finance.core.acn.mapper.SequenceIDMapper.updateByPrimaryKeySelective-Inline-sharp-sharp-sharp The error occurred while setting parameters-sharp-sharp-sharp SQL: update t_increment_sequence SET current_value =?, code =?

what result do you expect? What is the error message actually seen?

Apr.27,2021

you have misconfigured dataSource and performed a update operation in the read-only library, so if you report this error, check the configuration file and code to find the problem. I would like to ask what is the implementation of read-write separation using AOP? My previous project was to configure two data sources, MyBatis and Hibernate with different data sources.


think about it, only log

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1e5295f-451a2.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
