Question

我生产的资源并没有注入，虽然一切似乎都很好， LoggerProducer.java

import java.util.logging.Logger;

import javax.enterprise.inject.Produces;
import javax.enterprise.inject.spi.InjectionPoint;

 public class LoggerProducer {
        @Produces
        public Logger getLogger(InjectionPoint injectionPoint) {
            return Logger.getLogger(injectionPoint.getClass().getName());
        }
    }

LoggerServiceImpl.java

import java.util.logging.Logger;

import javax.enterprise.context.RequestScoped;
import javax.inject.Inject;
import javax.inject.Named;

import org.bala.java.jee.cdi.producer.control.LoggerService;


@RequestScoped
@Named("LoggerService")
public class LoggerServiceImpl implements LoggerService {
    @Inject
    Logger logger;

        /*
         * (non-Javadoc)
         * @see org.bala.java.jee.cdi.producer.control.LoggerService#getLoggingClass()
         */
        @Override
        public String getLoggingClass() {
            try {
                System.out.println(logger.getName());
            } catch (Exception e) {
                e.printStackTrace();
            }
            return logger.getName();
        }
    }

Answer 1

LoggerProducer不是托管bean，您需要使用适当的范围注释对其进行注释。

@producer的CDI @inject失败
