Java、Spring Boot、测试、entityManagerFactory

    我对春天的简单测试有一个奇怪的问题。下面是测试代码和堆栈跟踪。在主程序中有一些简单的数据库评估类:repository、entity、service和main。它们可以正常工作,并正确地对mysql db使用crud操作。但测试给出了我的例外。Jdk 9。

    @RunWith(SpringRunner.class)
    @SpringBootTest(classes = Demo4Application.class)
    public class MyJPATests {
    
        @Autowired
        BoardService boardService;
    
        @Test
        public void contextLoads() throws Exception {
            assertEquals(2, 2);
        }
    }
    

    这是我的stackTrace

    因为Java 9 JAXB是Java EE的一部分,您可能正在使用Java SE。

    要使JAXB API与Java SE 9配合使用,请使用以下命令: --add-modules java.xml.bind

    这里有更多详细信息: How to resolve java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException in Java 9
