我很難與澤西島測試框架一起工作。如何使用hk2注入自定義工廠?
我有一個根資源。
@Path("sample")
public class SampleResource {
@GET
@Path("path")
@Produces({MediaType.TEXT_PLAIN})
public String readPath() {
return String.valueOf(path);
}
@Inject
private java.nio.file.Path path;
}
我準備了一個工廠,提供path
。
public class SamplePathFactory implements Factory<Path> {
@Override
public Path provide() {
try {
return Files.createTempDirectory(null);
} catch (final IOException ioe) {
throw new RuntimeException(ioe);
}
}
@Override
public void dispose(final Path instance) {
try {
Files.delete(instance);
} catch (final IOException ioe) {
throw new RuntimeException(ioe);
}
}
}
還有一個活頁夾。
public class SamplePathBinder extends AbstractBinder {
@Override
protected void configure() {
bindFactory(SamplePathFactory.class).to(Path.class);
}
}
最後,我的測試類。
public class SampleResourceTest extends ContainerPerClassTest {
@Override
protected Application configure() {
final ResourceConfig resourceConfig
= new ResourceConfig(SampleResource.class);
resourceConfig.register(SamplePathBinder.class);
return resourceConfig;
}
}
當我試圖測試,我得到了。
org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=Path,parent=SampleResource,qualifiers={},position=-1,optional=false,self=false,unqualified=null,1916953383)
我做錯了什麼?
