org.mybatis.spring.SqlSessionTemplate

Thread safe, Spring managed, {@code SqlSession} that works with Springtransaction 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 {@code 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:

 {@code     }

  @Test
  public void testWithSqlSessionTemplate() {
    SqlSessionTemplate sessionTemplate = new SqlSessionTemplate(sqlSessionFactory);
    sqlSessionDaoSupport.setSqlSessionTemplate(sessionTemplate);
    sqlSessionDaoSupport.afterPropertiesSet();


    assertEquals("should store the Template", sessionTemplate, sqlSessionDaoSupport.getSqlSession());
  }

        .getSqlSession()).getSqlSessionFactory());
  }


  @Test
  public void testWithBothFactoryAndTemplate() {
    SqlSessionTemplate sessionTemplate = new SqlSessionTemplate(sqlSessionFactory);
    sqlSessionDaoSupport.setSqlSessionTemplate(sessionTemplate);
    sqlSessionDaoSupport.setSqlSessionFactory(sqlSessionFactory);
    sqlSessionDaoSupport.afterPropertiesSet();


    assertEquals("should ignore the Factory", sessionTemplate, sqlSessionDaoSupport.getSqlSession());
