类 SqlSessionTemplate

java.lang.Object

cn.jmicro.ext.mybatis.SqlSessionTemplate

所有已实现的接口:

Closeable, AutoCloseable, org.apache.ibatis.session.SqlSession

public class SqlSessionTemplate
extends Object
implements org.apache.ibatis.session.SqlSession

Thread safe, Spring managed, SqlSession that works with Spring transaction management to ensure that that the actual SqlSession used is the one associated with the current Spring transaction. In addition, it manages the session life-cycle, including closing, committing or rolling back the session as necessary based on the Spring transaction configuration.

The template needs a SqlSessionFactory to create SqlSessions, passed as a constructor argument. It also can be constructed indicating the executor type to be used, if not, the default executor type, defined in the session factory will be used.

This template converts MyBatis PersistenceExceptions into unchecked DataAccessExceptions, using, by default, a MyBatisExceptionTranslator.

Because SqlSessionTemplate is thread safe, a single instance can be shared by all DAOs; there should also be a small memory savings by doing this. This pattern can be used in Spring configuration files as follows:

 <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
   <constructor-arg ref="sqlSessionFactory" />
 </bean>
