虽然一切似乎都很好,但我生成的资源没有被注入(inject),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();
}
}

使用环境:

 Eclipse Version: Kepler Service Release 2
Java Version: jdk 7
Payara: payara41

最佳答案

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