我在Maven / Springboot项目中尝试运行（集成）测试时遇到错误。
我正在尝试初始化的对象上获得initializationError >> NoClassDefFound。
错误日志：

我的测试班：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("testcontext.xml")
public class TestSessionsIT {
@Autowired
private SessionService sessionService;
@Test
public void testGetSessions() {}
}
文件夹结构：
我的服务使用@Service注释进行注释。在testcontext.xml我有<context:component-scan base-package="ip2"/>
不知道如何解决此错误。任何帮助将非常感谢！
答案 0 :(得分：2)
终于找到了答案。
首先，我没有找到问题的根源，因此标题现在非常具有误导性。问题是Maven-failsafe-plugin没有找到spring boot类。解决方案是降级到2.18.1版。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.18.1</version>
</plugin>
