//避免报错，原因 obj 的属性多于 valueType 导致,添加一条语句即可
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
try {
reference = mapper.readValue(jsonValue,new TypeReference<ReferenceConfig<T>>() { });
//转换是会丢失注册地址信息，需要单独在将注册中心地址重新添加到该对象
reference.setRegistries(registries);
} catch (Exception e) {

将阿里dubbo的ReferenceConfig<T>对象从缓存中获取出对应的json字符串后，将其转换为ReferenceConfig<T>对象
