java - java.lang.ClassNotFoundException:org.junit.runners.BlockJUnit4ClassRunner

我从Eclipse执行spring 3.2.8项目的此Junit（junit-4.4）没问题，（单击右键-> Run As-> Junit Test）

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;


public class AccomodationTypeDaoTest extends BaseDaoTest {
    private AccomodationTypeDao accTypeDao;

    @Test
    public void testFindAll() {
        assertNotNull(accTypeDao.findAll());
    }

    @Autowired
    public void setAccomodationTypeDao(AccomodationTypeDao daoInstance) {
        this.accTypeDao = daoInstance;
    }

}



@SuppressWarnings("deprecation")
public class BaseDaoTest extends AbstractAnnotationAwareTransactionalTests {
    private static final String[] CONFIG_LOCATIONS = new String[] { "classpath:com/dao/testDataAccessContext.xml" };

    @Override
    protected String[] getConfigLocations() {
        return CONFIG_LOCATIONS;
    }

    @Test
    public void testBaseDaoTest() {
        assertTrue(true);
    }
}

我也没有问题，对包中的所有类都做同样的事情。

但是，当我单击测试文件夹/ MyProject / MyProjectWeb / test / src时，出现此异常：

最佳答案

在BlockJUnit4ClassRunner的javadoc中：

/**
 * [...]
 * </ul>
 *
 * @since 4.5
 */
public class BlockJUnit4ClassRunner

因此它在4.4中不可用，您可能无需任何代码更改即可升级到4.11
