MySQL Error: Could not retrieve transation read-only status server

Problem Description:after starting the transaction, the Java code makes a query, then inserts, which is reported at this time:        java.sql.SQLException:could not retrieve transation read-only status server

resolution process:

View MySQL 's things isolation level show VARIABLES like '%iso% ';

results returned: repeatable-read

change this to: read-committed: SET GLOBAL tx_isolation= ' read-committed ';

(Remember the Java Restart app, to be permanently active, change the My.ini configuration file )

Problem Analysis:

When the database isolation level is repeatable-read, querying a SELECT statement is also the beginning of things, and in hibernate, transactions that begin with a SELECT statement are marked as read-only transactions. At this point, the execution of the INSERT, UPDATE, DELETE and other DML statements will be error.
