我正在尝试在 Jersey 测试类中注入 HK2 Factory 服务提供的对象,但得到不满足的依赖项异常。
我有如下工厂服务
public class TestFactory implements Factory<TestObject>{
private final CloseableService closeService;
@Inject
public TestFactory(CloseableService closeService) {
this.closeService = closeService;
}
@Override
public TestObject provide() {
TestObject casualObject = new TestObject();
this.closeService.add(() -> dispose(casualObject));
return casualObject;
}
@Override
public void dispose(TestObject instance) {
instance.destroy();
}
}
还有一个泽西测试课
public class SampleTestCass extends JerseyTestNg.ContainerPerClassTest
{
//@Inject
private TestObject myTestObject;
private ServiceLocator locator;
@Override
protected Application configure()
{
ResourceConfig resConfig = new ResourceConfig(MyApi.class);
resConfig.register(getBinder());
locator = setupHK2(getBinder());
return resConfig;
}
// setup local hk2
public setupHK2(AbstractBinder binder)
{
ServiceLocatorFactory factory = ServiceLocatorFactory.getInstance();
ServiceLocator locator = factory.create("test-locator");
DynamicConfigurationService dcs = locator.getService(DynamicConfigurationService.class);
DynamicConfiguration dc = dcs.createDynamicConfiguration();
locator.inject(binder);
binder.bind(dc);
dc.commit();
return locator;
}
// get the binder
public AbstractBinder getBinder()
{
return new AbstractBinder() {
@Override
protected void configure() {
bindFactory(TestFactory.class, Singleton.class).to(TestObject.class).in(PerLookup.class);
}
}
}
@BeforeClass
public void beforeClass()
{
myTestObject = locator.getService(TestObject.class);
// use myTestObject
}
@AfterClass
public void afterClass()
{
if (locator != null) {
locator.shutdown();
}
}
@Test()
public void someTest()
{
// some test code...
}
}
并低于例外
MultiException 有 3 个异常。他们是:
- org.glassfish.hk2.api.UnsatisfiedDependencyException:SystemInjecteeImpl 没有可用于注入的对象(requiredType=CloseableService,parent=TestFactory,qualifiers={},position=0,optional=false,self=false,unqualified=null,2053349061 )
- java.lang.IllegalArgumentException:在尝试解决 com.test.factories.TestFactory 的依赖项时发现错误
- java.lang.IllegalStateException:无法执行操作:在 com.test.factories.TestFactory 上解析
