Java 利用Spring transactionManager进行集成测试

我已经有一段时间了&有种下沉的感觉，我忽略了一些愚蠢的事情。我试图使用事务管理器进行一个非常简单的集成测试，但似乎无法让它像我认为应该的那样回滚

测试类别：

public class JdbcUserDAO implements UserDAO {

@Autowired
private DataSource dataSource;

private static final String TERM_USER_SQL =
        "UPDATE USER " +
        "SET TERM_DATE = date('now') " +
        "WHERE USER_NAME = ?";

@Override
public void terminateUser(String userName) {

    try (Connection conn = dataSource.getConnection()){
        PreparedStatement stmt = conn.prepareStatement(TERM_USER_SQL);
        stmt.setString(1, userName);
        stmt.executeUpdate();
    } catch (SQLException e) {
        throw new RuntimeException("Caught SQLException in persistence service", e);
    }
}

Spring上下文（applicationContext.xml）：

好的，TransactionConfiguration的defaultRollback行为是“true”，默认transactionManager bean名称是“transactionManager”，所以我应该在那里设置。我运行这个测试，并期望“TERM_DATE”列在测试完成后恢复为“null”（其起始值），但它不是（我在测试完成后查询，可以看到它仍然是=今天的日期）

我甚至得到了看起来非常有前途的日志：

Jun 17, 2014 1:25:48 PM org.springframework.test.context.transaction.TransactionalTestExecutionListener startNewTransaction
INFO: Began transaction (1): transaction manager [org.springframework.jdbc.datasource.DataSourceTransactionManager@10279954]; rollback [true]

INFO: Closing org.springframework.context.support.GenericApplicationContext@3304e92a: startup date [Tue Jun 17 13:25:48 MDT 2014]; root of context hierarchy

我到底忽略了什么？？？非常感谢

使用

DataSourceUtils.getConnection（dataSource）

而不是

dataSource.getConnection（）

。前者为事务性支持准备连接，而后者只是绕过Spring事务性基础架构，要求您处理事务性细节。

如果您使用Spring，请不要编写样板JDBC代码

相反，使用Spring的

JdbcTemplate

，它会自动与当前Spring管理的事务一起工作，消除所有样板JDBC代码

您应该用以下内容替换整个DAO实现：

public class JdbcUserDAO {

    private static final String TERM_USER_SQL = "UPDATE USER "
            + "SET TERM_DATE = date('now') WHERE USER_NAME = ?";

    private final JdbcTemplate jdbcTemplate;

    @Autowired
    public JdbcUserDAO(DataSource dataSource) {
        this.jdbcTemplate = new JdbcTemplate(dataSource);
    }

    public void terminateUser(String userName) {
        jdbcTemplate.update(TERM_USER_SQL, userName);
    }

}

问候,

只是为了好玩，你愿意用SQLite交换H2或HSQL吗？我怀疑这是问题所在，但确保这一点不会有什么坏处：）有趣的是，你提到了这一点-真正的代码使用了Oracle，但我切换到SQLite以消除这一问题：）谢谢你，山姆-你搞定了。可悲的是，我真的不知道如何使用JDBC，但我真的很盲目（我花了<15分钟的时间重构到JdbcTemplate，效果非常好。如果有人以上面的代码为例，我完成的代码看起来几乎与Sam的完全相同-我唯一改变的是从上下文中去掉了“注释驱动”标记。再次感谢！
