我正在尝试使 CDI 在 JBeret SE 上工作。这是我的代码:
SampleBatchlet 类
@Named
public class SampleBatchlet extends AbstractBatchlet
{
@Inject
@BatchProperty(name = "foo")
String foo;
@Inject
StepContext stepContext;
@Inject
Logger logger;
@Override
public String process() throws Exception {
final String say = stepContext.getProperties().getProperty("say");
System.out.println("hello foolish");
return null;
}
}
SampleBatchletTest 类
@EnableWeld
class SampleBatchletTest {
@Inject
Logger logger;
@WeldSetup
public WeldInitiator weld = WeldInitiator
.from(
LoggerProducer.class
)
.activate(
RequestScoped.class,
ApplicationScoped.class
)
.build();
@Test
void app() throws InterruptedException {
final JobOperator jobOperator = BatchRuntime.getJobOperator();
long id = jobOperator.start("simplebatchlet", null);
final JobExecutionImpl jobExecution = (JobExecutionImpl) jobOperator.getJobExecution(id);
jobExecution.awaitTermination(5, TimeUnit.SECONDS);
Assertions.assertEquals(BatchStatus.COMPLETED, jobExecution.getBatchStatus());
}
}
服务器类
@ApplicationScoped
public class Server {
@Inject
private Logger logger;
public void init(@Observes @Initialized(ApplicationScoped.class) Object init) throws InterruptedException {
logger.info("init");
}
LoggerProducer 类
public class LoggerProducer {
@Produces
public Logger produceLogger(InjectionPoint injectionPoint) {
return LoggerFactory.getLogger(injectionPoint.getMember().getDeclaringClass().getName());
}
}
问题是 Logger 实例未在 SampleBatchlet 上注入,而在上面的测试和服务器类中正确注入。
有什么提示吗?
小更新
通过阅读此参考资料
https://jberet.gitbooks.io/jberet-user-guide/content/batch_properties/
我发现 java.util.logging.Logger 可以被注入。
因此我添加了
<batchlet ref="it.infocert.shop.main.SampleBatchlet" >
<properties>
<property name="logger" value="java.util.logging.Logger" />
</properties>
</batchlet>
价值实际上可以是任何东西..
在 SampleBatchlet 上我添加了
@Inject
@BatchProperty
Logger logger;
现在它被注入了。顺便说一句,我有点困惑,因为我希望使用另一个记录器实现..
