I'd like always "autocommit = false"

jdbc8.4 does keep autocommit= false;

While 9.0 set default autocommit = true -> this is NOT what I want.

Setup is in spring configuration file:
=========================================
applicationContext-mybatis.xml

<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
       <property name="driverClassName" value="${driverClassName}" />
       <property name="url"             value="${url}"      />
       <property name="username"        value="${username}" />
       <property name="password"        value="${password}" />
</bean>

mybatis does not have a parameter needed for autoCommit=false. The
default is false for JDBC8.4 driver.

For Spring3.0.5 + mybatis3 + jdbc9, how do you setup autoCommit = false?

The default for 8.4 is false, while jdbc9 always get "Cannot commit when
autoCommit is enabled" Exception". Where should I specify autoCommit =
false for jdbc9 in spring frame work?

This is exactly what I had and I need for jdbc9 as well. But jdbc9
returns autoCommit = true ?

Exactly.

I need to know in spring3.0.5 + mybatis + jdbc9 where to setup
autocommit= false.

For spring3.0.5 + mybatis + jdbc8, the default is autocommit = false.

Thank you,
