自动连接服务在jsf Converter中为空

Question

我无法在jsf转换器中使用@Autowired注入服务:

转换器:

@Component("advertiserConverter")
@FacesConverter("advertiserConverter")
public class AdvertiserConverter implements Converter , Serializable {

 @Autowired
 private IAdvertiserService advertiserService;

 public Object getAsObject(FacesContext context, UIComponent component, String value) {
    if (value == null || value.length() == 0) {
        return null;
    }
    Long id = Long.parseLong(value);
    return advertiserService.findAdvertiser(id);
 }

 public String getAsString(FacesContext context, UIComponent component, Object value) {
    return value instanceof Advertiser ? ((Advertiser) value).getId().toString() : "";
 }
}

applicationContext.xml中:

<context:annotation-config />
<context:component-scan base-package="com.test.example"/>
<tx:annotation-driven />

服务:

@Service
@Transactional
public class AdvertiserServiceImpl implements IAdvertiserService {

}

Answer 1

最后我找到了解决方案:

转换器:

@Service
public class AdvertiserConverter implements Converter{

XHTML:

converter="#{advertiserConverter}"

代替

converter="advertiserConverter"
