Java 弹簧试验'；s@Rollback不'；不要回滚任何东西

工作代码如下：

//import everything

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = Test2.TestConfiguration.class)
@Transactional
public class Test2 {

    @Autowired
    private DataSource datasource;

    @BeforeTransaction
    public void createDatabase() throws SQLException {
        DataSourceUtils .getConnection(datasource)
                        .createStatement()
                        .execute("CREATE TABLE USERS (id bigint, size bigint, primary key (id))");
    }

    @Rollback
    @Test
    public void test() throws SQLException {
        DataSourceUtils .getConnection(datasource)
                        .createStatement()
                        .execute("INSERT INTO USERS VALUES (5, 5)");
    }

    @AfterTransaction
    public void dropTable() throws SQLException {
        ResultSet rs = DataSourceUtils  .getConnection(datasource)
                                        .createStatement()
                                        .executeQuery("SELECT * FROM USERS");
        boolean isEmpty = !rs.next();
        if (isEmpty) {
            System.out.println("Rollback succeeded");
        } else {
            System.out.println("Rollback failed");
        }
        rs.close();

        datasource  .getConnection()
                    .createStatement()
                    .execute("DROP TABLE USERS");
    }

    @Configuration
    public static class TestConfiguration {

        @Bean
        public DataSource driverManagerDataSource() {
            DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
            String dbURI = "database/tests/DerbyDB/db";
            String connectionString = "jdbc:derby:" + dbURI;
            if (!new File(dbURI).exists()) connectionString += ";create=true";
            driverManagerDataSource.setUrl(connectionString);
            driverManagerDataSource.setDriverClassName("org.apache.derby.jdbc.EmbeddedDriver");
            return driverManagerDataSource;
        }

        @Bean
        public PlatformTransactionManager platformTransactionManager() {
            PlatformTransactionManager ptm = new DataSourceTransactionManager(driverManagerDataSource());
            return ptm;
        }
    }
}

已解决问题： 我想在每次测试后使用@rollback注释回滚数据库状态。不幸的是，它不起作用

这是我的测试课：

//import everything

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = Test2.TestConfiguration.class)
@Transactional
public class Test2 {

    @Autowired
    private DataSource datasource;

    @BeforeTransaction
    public void createTable() throws SQLException {
        datasource  .getConnection()
                    .createStatement()
                    .execute("CREATE TABLE USERS (id bigint, size bigint, primary key (id))");
    }

    @Rollback
    @Test
    public void test() throws SQLException {
        datasource  .getConnection()
                    .createStatement()
                    .execute("INSERT INTO USERS VALUES (5, 5)");
    }

    @AfterTransaction
    public void dropTable() throws SQLException {
        ResultSet rs = datasource   .getConnection()
                                    .createStatement()
                                    .executeQuery("SELECT * FROM USERS");
        boolean isEmpty = !rs.next();
        if (isEmpty) {
            System.out.println("Rollback succeeded");
        } else {
            System.out.println("Rollback failed");
        }
        rs.close();

        datasource  .getConnection()
                    .createStatement()
                    .execute("DROP TABLE USERS");
    }

    @Configuration
    public static class TestConfiguration {

        @Bean
        public DataSource driverManagerDataSource() {
            DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
            String dbURI = "database/tests/DerbyDB/db";
            String connectionString = "jdbc:derby:" + dbURI;
            if (!new File(dbURI).exists()) connectionString += ";create=true";
            driverManagerDataSource.setUrl(connectionString);
            driverManagerDataSource.setDriverClassName("org.apache.derby.jdbc.EmbeddedDriver");
            return driverManagerDataSource;
        }

        @Bean
        public PlatformTransactionManager platformTransactionManager() {
            PlatformTransactionManager ptm = new DataSourceTransactionManager(driverManagerDataSource());
            return ptm;
        }
    }
}

Spring声称它回滚了数据库，但事实并非如此，因为记录仍然存在。

据我所知，您正在测试方法中手动创建一个新的、独立的Spring上下文，它在初始化过程中创建表

由于该上下文使用它自己的事务管理器和数据源，因此它不会受到

@Rollback

注释的影响-该注释是在为整个测试类定义的（隐式）spring上下文的上下文中处理的

---

还要注意的是，在某些数据库中，您无法回滚

CREATE

命令（但不确定Derby）

---

更新

另一个问题是，当您通过

datasource.getConnection（）

获取连接时，实际上没有使用事务管理器

从文件：

通过

DataSourceUtils.getConnection（DataSource）

检索JDBC连接需要应用程序代码，而不是标准的Java EE样式

DataSource.getConnection（）

调用。Spring类，如

JdbcTemplate

隐式使用此策略

---

我认为

printTableName（）

方法中的这一行

con.close（）；

导致了这个问题

事务在关闭连接时提交

---

最好使用entitymanager或来处理事务。

不幸的是，删除

con.close（）；

并不能解决问题。@Tyvrel是否尝试显式回滚？

con.rollback（）

当然。它也不起作用。而且没有抓住要点-我需要了解

@Rollback

是如何工作的，我想不出比执行简单的sql脚本更简单的练习。

con.close（）

关闭一个通过编程创建的非mana连接
