我有一个接口Repository
,有两个实现,DBRepository
和UTRepository
。 UTRepository
带有@Alternative
注释,我正在尝试在JUnit测试中使用它。
测试类:
@RunWith(Arquillian.class)
public class UserServiceTest {
@Inject
private UserService service;
@Deployment
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class)
.addClasses(Repository.class, UserService.class, UTRepository.class)
.addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
}
@Test
public void addCharacterTest() {
service.addCharacter(1L, Mockito.mock(GameCharacter.class));
}
}
被测课程:
public class UserService {
@Inject
Repository repository;
@Transactional
public void addCharacter(Long userId, GameCharacter character) {
User user = repository.readById(userId, User.class);
user.addCharacter(character);
repository.update(user);
}
}
我的beans.xml
文件(放在src / test / webapp / WEB-INF / beans.xml中):
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/beans_1_2.xsd"
bean-discovery-mode="all">
<alternatives>
<class>org.package.name.UTRepository</class>
</alternatives>
</beans>
当我尝试运行测试时,出现异常:

出什么问题了?
答案 0 :(得分:1)
您找到的解决方案效果很好,只是为了完善。
基本上,您需要添加beans.xml
,这将启用您的替代方法。 EmptyAsset.INSTANCE
将导致空bean.xml在这种情况下不会被剪切。
但是,在您的解决方案中,您放置在beans.xml
下的src/test/webapp/WEB-INF/beans.xml
没有任何作用。 如果要利用现有的beans.xml
文件,可以使用:
addAsManifestResource(File resource, String target)
,其中添加给定的File
,名称为target
addAsManifestResource(Package resourcePackage, String resourceName, String target)
,您可以仅指定文件所在的软件包,然后指定其名称,并在部署中指定文件的名称答案 1 :(得分:0)
问题似乎出在.addAsManifestResource
参数上。我必须将StringAsset
与Arquillian将添加到beans.xml的替代方法一起使用,而不是一个空实例。
现在是createDeployment()
方法:
@Deployment
public static JavaArchive createDeployment() {
return ShrinkWrap.create(JavaArchive.class)
.addClasses(Repository.class, UserService.class, UTRepository.class)
.addAsManifestResource(new StringAsset("<alternatives><class>org.package.name.repositories.UTRepository</class></alternatives>"), "beans.xml");
}
