org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [beans-b.xml]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/context/index/CandidateComponentsIndexLoader
這個是在單元測試的時候出現的錯誤，好像顯示的是無法找到spring framework中的某個類，但是我在配置的過程中dataSource是沒問題的，
錯誤應該是出在EntityManagerFactory裏，但是那段代碼我是直接複製過來的，包掃描的包名也被我改了，所以出了什麽錯誤請大家指正

public class SpringDataTest {
/**

private ApplicationContext ctx;
@Before
public void Setup(){
System.out.println("setup!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
ctx = new ClassPathXmlApplicationContext("beans-b.xml");
System.out.println("setup!!!");
}
@After
public void tearDown(){
ctx = null;
}
@Test
public void testEntityManagementFactory(){
}
}這個是測試代碼
