使用dbunit和Spring的问题(没有spring-test-dbunit)

我尝试使用dbunit来测试我的DAO。我们在与spring-test-dbunit不兼容的版本中使用Spring。我无法将我的dao bean自动装入我的测试类,因为那时我必须使用@RunWith(SpringJUnit4ClassRunner.class)来关注一个无参数构造函数。我的班级如下:

public class DbUnitExample extends DBTestCase {

    @Autowired
    public MyDAO myDAO;


    public DbUnitExample(String name) {
        super(name);
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_DRIVER_CLASS, "com.mysql.jdbc.Driver");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_CONNECTION_URL, "...");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_USERNAME, "...");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_PASSWORD, "...");
    }

    @Override
    protected IDataSet getDataSet() throws Exception {
        return new FlatXmlDataSetBuilder().build(new FileInputStream("target/partial.xml"));
    }

    @Override
    protected DatabaseOperation getSetUpOperation() throws Exception {
        return DatabaseOperation.REFRESH;
    }

    @Override
    protected DatabaseOperation getTearDownOperation() throws Exception {
        return DatabaseOperation.NONE;
    }

    @Test
    public void testSometing() throws Exception {
        myDAO.deleteById(12662);
    }
}

当然我得到了一个N​​PE,因为我的dao bean无法找到。当我使用@RunWith(SpringJUnit4ClassRunner.class)时,我需要提供一个无参数构造函数,并且必须删除我的" dbunit" -constructor。有没有使用spring-test-dbunit将dbunit与spring一起使用的标准方法或解决方法

修改

我的班级现在看起来如下:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/test-application.xml")
@DirtiesContext
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class })
public class DbUnitExample extends DBTestCase {

    @Autowired
    public MyDAO myDAO;

    public DbUnitExample() {
        super("target/partial.xml");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_DRIVER_CLASS, "com.mysql.jdbc.Driver");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_CONNECTION_URL, "...");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_USERNAME, "...");
        System.setProperty(PropertiesBasedJdbcDatabaseTester.DBUNIT_PASSWORD, "...");
    }

    @Override
    protected IDataSet getDataSet() throws Exception {
        return new FlatXmlDataSetBuilder().build(new FileInputStream("target/partial.xml"));
    }

    @Override
    protected DatabaseOperation getSetUpOperation() throws Exception {
        return DatabaseOperation.REFRESH;
    }

    @Override
    protected DatabaseOperation getTearDownOperation() throws Exception {
//      return DatabaseOperation.NONE;
//      return DatabaseOperation.REFRESH;
        return DatabaseOperation.CLEAN_INSERT;
    }

    @Test
    public void testSometing() throws Exception {
        myDAO.deleteById(12662);
    }
}

它现在编译,但没有dbunt功能,这意味着如果我删除一行,它就不会恢复到之前的状态(再次插入)。

由于您使用的是Spring,我建议将dbUnit实例自动装入测试中。 dbUnit Test Cases pagePrepAndExpectedTestCase提供了“使用Spring的配置示例”,但只需复制代码并将其更改为DBTestCase并进行相应调整。
