我叫两种方法，第一种方法更新一个表，第二种方法在另一个表中插入一条记录。当第二笔交易失败时，EJB它不会回退第一笔交易。

这是我的支持豆：

@ManagedBean
@ViewScoped
public class TransactionTestBean implements Serializable {

    @EJB
    private TransactionTestService service;

    public String loadView() {
        return "/test/transactionTest";
    }

    public void test() {
        try {
            service.updateTest();
        } catch (Exception e) {
        }
    }
}

EJB接口：

@Local
public interface TransactionTestService {

    void updateTest() throws CustomException;
}

EJB类：

@Stateless
@TransactionManagement
public class TransactionTestServiceImpl implements TransactionTestService {

    @Resource(mappedName = "java:jboss/datasources/xxxxxDS", shareable = true)
    public DataSource dataSource;

    private TransactionTestDAO dao;

    @PostConstruct
    public void init() {
        dao = new TransactionTestDAOImpl();
    }

    @PreDestroy
    public void destroy() {
        dao = null;
    }

    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRED)
    public void updateTest() throws CustomException {

        try (Connection connection = dataSource.getConnection()) {
            dao.updateRecord(connection);
            // dao.saveRecord(connection);
        } catch (SQLException exception) {
            throw new CustomException(exception, exception.getMessage());
        }
    }
}

我的自定义例外：

@ApplicationException(rollback = true)
public class CustomException extends Exception {

    public CustomException(Throwable cause, String message) {
        super(message, cause);
    }
}

编辑：

添加了DAO类：

public class TransactionTestDAOImpl implements TransactionTestDAO {

    @Override
    public void updateRecord(Connection connection) throws CustomException {

        PreparedStatement preparedStatement = null;

        try {
            preparedStatement = connection.prepareStatement("UPDATE table_x SET field_x = ? WHERE field_y = 1");
            preparedStatement.setInt(1, 1);
            preparedStatement.executeUpdate();
        } catch (Exception exception) {
            throw new CustomException(exception, exception.getMessage());
        } finally {
            if (preparedStatement != null) {
                try {
                    preparedStatement.close();
                } catch (SQLException sqlException) {
                }
            }
        }
    }
}

和DAO接口：

public interface TransactionTestDAO {

    void updateRecord(Connection connection) throws CustomException;
}
