我正在尝试运行 TestNG+Spring+JPA+Hibernate 'Hello World' 测试。执行导致 NullPointerException，tile 配置器 bean 失败。

例外：

我的applicationContext.xml，只显示tiles config bean def：

<bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
<property name="definitions">
    <list>
        <value>/WEB-INF/tiles/tiles.xml</value>
    </list>
</property>
</bean>

做了很多谷歌搜索，唯一发现的是，人们提到 cglib 和/或 asm jar 与 spring 和 hibernate 依赖项冲突。我认为这在这里不适用，但是我的 lib 文件夹有以下 jars，抱歉不按顺序排列：

测试类如下：

@ContextConfiguration(locations = { "classpath:test-servlet.xml" })
public class FacultyDaoTest extends AbstractTransactionalTestNGSpringContextTests {

    private final XLogger logger = XLoggerFactory.getXLogger(FacultyDaoTest.class);

    @Inject
    FacultyDAO facultyDao;

    @BeforeClass
    public void setUp() {
        logger.entry();    
        System.out.println("Inside setup");    
    }

    @Test(groups = { "fast" })
    @Rollback(value = false)
        public void createFaculty() {
        Faculty f = new Faculty();
        f.setFirstName("John");
        f.setLastName("Frost");
        f.setCpsoNumber("23198");

        f = facultyDao.makePersistent(f);

        assert(f.getId() > 0);    
    }

    @Test(groups = { "fast" })
    public void aFastTest() {
        logger.entry();    
        logger.info("Inside a Fast test");
    }

    @Test(groups = { "slow" })
    public void aSlowTest() {
        logger.entry();    
        logger.info("Inside a Slow test");
    }
}

任何指针将不胜感激。

您的测试加载了特定于 Web 应用的配置文件，但您的测试环境未提供所需的文件：

您需要将 Web 应用程序特定配置与没有 Web 应用程序上下文的工作分开。

然后使用没有 Web 应用程序的测试。

对你来说，这意味着：删除测试配置的 Tiles Configuration。因为在测试中该 /WEB-INF/tiles/tiles.xml文件不可用。
