使用 J2EE 和 Jboss 在每次测试后回滚

Question

我在上一个项目中使用的是 hibernate + Spring。设置持久性测试非常容易，因为在测试类的顶部使用以下注释，每次测试后数据库中的更改都会回滚。

@TransactionConfiguration(defaultRollback=true)

现在我将 J2EE 与 arquillian 和 Jboss 应用服务器一起使用。有没有类似的方法？

Answer 1

据谷歌告诉我，@TransactionConfiguration 是 Spring Framework 4.0 的一部分。 所以你应该在你的新项目中包含 Spring——即使它只是为了测试。

Answer 2

改为使用内存数据库。更快，不必担心回滚。

您可以在每次测试之前或在每个套件之前运行完整的架构创建。

触发器、Sprocs 等更多问题 - 但无论如何你都不应该使用它们。

例如子类化这个

public class BaseTest {
    private static EJBContainer ejbContainer;

        @Resource
        protected DataSource dataSource;
        protected String dataFilename = "data.sql"; // the default can be overriden in subclass

        @BeforeClass
        public static void startTheContainer() throws Exception {

            // boot the container and perform dependency injection
            final Properties p = new Properties();
            p.put("yourDB", "new://Resource?type=DataSource");
            p.put("yourDB.JdbcDriver", "org.hsqldb.jdbcDriver");
            String schema = System.getProperty("testDatabaseSchema", "racing");
            p.put("yourDB.JdbcUrl", "jdbc:hsqldb:mem:" + schema);
            p.put("yourDB.TestOnBorrow", "false");
            p.put("javax.persistence.provider", "org.hibernate.ejb.HibernatePersistence");
            p.put("openejb.embedded.remotable", "false");
            p.put("openejb.descriptors.output", "false");
            p.put("openejb.jmx.active", "false");
            p.put("hsql.disabled", "false");

            // Logging config
            // Info from http://openejb.apache.org/configuring-logging-in-tests.html
            p.put("log4j.appender.C.layout", "org.apache.log4j.PatternLayout");
            p.put("log4j.appender.C.layout.ConversionPattern", "%-5p %d{ABSOLUTE} %c: %m%n");
            p.put("log4j.category.OpenEJB.options", "warn");

            ejbContainer = EJBContainer.createEJBContainer(p);

        }

        @AfterClass
        public static void afterClass() {
            if (ejbContainer != null) {
                ejbContainer.close();
            }
        }

        @Before
        public void setUp() throws Exception {
            ejbContainer.getContext()
                        .bind("inject", this);

            // check everything booted ok and is ready to go
            assertNotNull("Data source is null", dataSource);

            // setup database with SQL script
            final Connection connection = dataSource.getConnection();
            try {
                String script = getScript("schema.ddl");
                final Statement statement = connection.createStatement();
                statement.execute(script);
                String dataScript = getScript(dataFilename);
                final Statement dataStatement = connection.createStatement();
                dataStatement.execute(dataScript);
                connection.commit();
            } finally {
                connection.close();
            }
        }


        @After
        public void tearDown() throws Exception {
            final Connection connection = dataSource.getConnection();
            try {
                final Statement stmt = connection.createStatement();
                stmt.execute("DROP SCHEMA PUBLIC CASCADE");
                connection.commit();
            } finally {
                connection.close();
            }
        }

        protected String getScript(String scriptFilename) throws Exception {
            URL url = Resources.getResource(scriptFilename);
            return Resources.toString(url, Charsets.UTF_8);
        }
