@IocBean(create = "createRedis")
public class RedisStarter {

    @Inject
    protected PropertiesProxy conf;

    @Inject("refer:$ioc")
    protected Ioc ioc;

    // @IocBean(name = "redis")
    public void createRedis() {
        // 扫描所有redisName
        String regex = "redis\\.(\\w*)\\.host";
        for (String key : conf.getKeys()) {
            Pattern pattern = Regex.getPattern(regex);
            Matcher match = pattern.matcher(key);
            if (match.find()) {
                // 获取redisName
                String redisName = match.group(1);
                if(!redisName.equals("local")) { // local会在最后默认处理
                    Redis redis = new Redis(redisName, conf);
                    ioc.addBean(redisName + "Redis", redis);
                }
            }
        }
        // return new Redis("local", conf); // 注入默认redis，如果没有配置local，但用户使用了默认redis，则会抛出异常 throw Lang.makeThrow("未连接到Redis，请检查配置项");
    }
}

上面有 @IocBean(name = "redis") return new Redis("local", conf); 被我注解掉了，没注解之前勉强正常
勉强正常的意思是这样

    @Inject
    Redis aaaRedis;

    @Inject
    Redis adRedis;

   // 以上 aaaRedis对象里面为空

    @Inject
    Redis redis;
    @Inject
    Redis aaaRedis;

    @Inject
    Redis adRedis;

    // 以上redis为空  aaaRedis正常
