MySQL之查看默認的事物隔離級別

1.切換到performance_schema database下

    List-1 查看當前用的是哪一個database

mysql> select database();
+--------------------+
| database()         |
+--------------------+
| performance_schema |
+--------------------+
1 row in set (0.01 sec)

2.用以下命令

    List-2 

mysql> select * from global_variables where variable_name like "%tx%";
+---------------+-----------------+
| VARIABLE_NAME | VARIABLE_VALUE  |
+---------------+-----------------+
| tx_isolation  | REPEATABLE-READ |
| tx_read_only  | OFF             |
+---------------+-----------------+
2 rows in set (0.01 sec)

    List-2中能夠看出事物隔離級別是repeatable-read；事物的read-only是被關閉的，這個tx_read_only在Spring的註解上能夠經過@Transactional來修改。
