の作業コードをロールバックしません。不幸にもそれはうまくいかない。記録が残っているので、春のテストの@Rollbackは、以下のもの
//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;
}
}
}
春はそれが真実ではないデータベースを、ロールバック主張:
は、ここに私のテストクラスです。
どのように動作させるのですか?

あなたは '@ContextConfiguration(classes = TestDerbyDatabaseInitializer.TestConfiguration.class)'でテストクラスに注釈をつけて、implictコンテキストを削除すると '@ Rollback'アノテーションが動作するのでしょうか? – Tyvrel
1) '@ ContextConfiguration'アノテーションで作成されたSpringコンテキストを使う必要があります。混乱を避けるために他のコンテキストを作成しない、2)誤って管理されていない接続を使用しないようにプログラムでデータベースへの他の接続をプログラムで作成しない( 'DriverManager.getConnection()')、3)ロールバックすることができます(つまり'INSERT'ではなく' CREATE TABLE') - '@ BeforeTransaction'メソッドでデータベースを作成します。 –
ありがとうございました。その答えは、Springのテストについてもっと理解してくれました。また、私はあなたのコメントに応じてコードを更新しましたが、私はまだそれを働かせることはできません。 – Tyvrel
