---------------------------------
Hi, [~giovanni.fumarola] . Thanks for code review.
The h2database used by the unit test, I use it to test MySQL and MSSQLServer.
It can emulate MySQL and MSSQLServer in memory mode.
Mainly used in the following two unit tests, use special connection strings to
simulate different databases.
*TestStateStoreMSSQLServer.java*
{code:java}
// TestStateStoreMSSQLServer.class
String driver = "org.h2.jdbcx.JdbcDataSource";
String databaseUrl
= "jdbc:h2:mem:db1;MODE=MSSQLServer;"
+ "DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE";
{code}
*TestStateStoreMySQL.java*
{code:java}
//TestStateStoreMySQL.class
String driver = "org.h2.jdbcx.JdbcDataSource";
String databaseUrl =
"jdbc:h2:mem:db1;MODE=MySQL;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE";
{code}
