简单的策略模式

定义策略通用类

public interface ChannelStrategy {

 
    List<ClientDto> test(OpenClient openClient);


}

 

@Slf4j
@Component(ChennelConstant.JD)
public class TFenXiaoChannelStrategy implements ChannelStrategy {
　　

　　@Override

　　List<ClientDto> test(OpenClient openClient){
　　}

}

 

注入策略

@Service
@Slf4j
public class ChannelStrategy {
    @Autowired
    private final Map<String, ChannelStrategy> strategys = new ConcurrentHashMap<>(6);

    public ChannelStrategy getStrategy(String channel){
        ChannelStrategy strategy = strategys.get(channel);
        if (strategy == null) {
            log.warn("not find strategy defined");
            return null;
        }
        return strategy;
    }
}

 根据渠道获取策略

 ChannelStrategy strategy = middleChannelStrategy.getStrategy(openClientShop.getChannel());

　　strategy.test();
