我已经为基于Spring-MVC的项目编写了一些测试用例。由于项目规模巨大，我们正在使用2个数据源和2个事务管理器，它们都使用HikariPool与同一个数据库进行通信。
使用webapp时，如果我使用第一个数据源保存对象并使用第二个数据源检索对象，则该对象工作正常，但在运行mvn test时却无法正常工作。
有什么想法吗？
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"file:src/main/webapp/WEB-INF/spring/appServlet/servlet-context.xml",
"file:src/main/webapp/WEB-INF/spring/root-context.xml", "file:src/main/webapp/WEB-INF/spring/appServlet/security-applicationContext.xml"})
@Ignore
@WebAppConfiguration
@Transactional
public class TestingController {
//All autowired dependencies
}
代码失败的DAO层：
@Repository
@Transactional
public class GroupNotesDAOImpl implements GroupNotesDAO {
@Autowired
@Qualifier(value = "sessionFactory_origin")
private final SessionFactory sessionFactory;
@Autowired
@Qualifier(value = "sessionFactory_extended")
private final SessionFactory sessionFactory_extended;
@Override
public GroupNotes getGroupNoteByIdExtended(int id){
Session session = this.sessionFactory_extended.getCurrentSession();
System.out.println("Id of note is "+id);
// Getting null below, even though the object exists, id is non-zero
return (GroupNotes) session.get(GroupNotes.class, id);
}
}
在浏览器中，一切正常。扩展的数据源用于长期运行的服务。
保存DAO代码：
@Override
public int saveGroupNoteAndReturnId(GroupNotes mnotes, int msectionid) {
Session session = this.sessionFactory.getCurrentSession();
if(mnotes.getCanvasId()!=0) {
GroupSection groupSection = (GroupSection) session.get(GroupSection.class, msectionid);
groupSection.getSectionsnotes().add(mnotes);
mnotes.setOwnednotes(groupSection);
int saveId = (Integer) session.save(mnotes);
session.flush();
return saveId;
}else {
return 0;
}
}
测试用例：
// First test calls the save method
groupNotes = TestUtils.createGroupNotes("testtag", "testtext", loggedInUser.getId());
groupNotes.setCanvasId(mcanvasId);
int noteId = this.groupNotesService.saveGroupNoteAndReturnId(groupNotes, msectionId);
assert noteId!=0;
The 2nd test calls to retrieve the object for duplicating. As duplication is a long run process, it's executed with extended transaction manager
int success =this.groupNotesService.duplicateGroupNote(noteId, msectionId, groupId, true,true,4.0,false);
assert(success!=0);
