完整配置如下
`dubbo:
application:
logger: slf4j
# 元数据中心 local 本地 remote 远程 这里使用远程便于其他服务获取
metadataType: local
# 可选值 interface、instance、all，默认是 all，即接口级地址、应用级地址都注册
register-mode: instance
service-discovery:
# FORCE_INTERFACE，只消费接口级地址，如无地址则报错，单订阅 2.x 地址
# APPLICATION_FIRST，智能决策接口级/应用级地址，双订阅
# FORCE_APPLICATION，只消费应用级地址，如无地址则报错，单订阅 3.x 地址
migration: FORCE_APPLICATION
# 注册中心配置
registry:
address: nacos://${spring.cloud.nacos.server-addr}
group: DUBBO_GROUP
parameters:
namespace: ${spring.profiles.active}
metadata-report:
check: true
reportMetadata: false
reportDefinition: false
# 消费者相关配置
protocol:
# 如需使用 Triple 3.0 新协议 可查看官方文档
# 使用 dubbo 协议通信
name: dubbo
# dubbo 协议端口(-1表示自增端口,从20880开始)
port: -1
consumer:
# 结果缓存(LRU算法)
# 会有数据不一致问题 建议在注解局部开启
cache: false
# 支持校验注解
validation: jvalidationNew
# 调用重试 不包括第一次 0为不需要重试
retries: 0
# 初始化检查
check: false`

1. Please comment in English because we want all the users know what we are talking about.
2. Using of local or remote metadata or not is depend on provider side. If a provider only export in remote mode, consumer should use it.
3. Except these, application level serivce discovery also require metadata center of save and read the mapping of interface name and application name.

我就是应用级服务发现啊 FORCE_APPLICATION 我已经关闭了 reportDefinition 应该是不会推送了才对啊

I have set local globally
There is no data in the metadata center, and consumers can still start successfully.
According to the description of 3, that is to say, local storage cannot be used in any case, and remote storage is required. Is there a problem with this understanding?

所以我觉得这块是有问题的 希望官方可以测一测 以前用local不启动生产者是无法启动消费者的
消费者启动的时候会去调用生产者的接口 现在升级了3.2.X以后 就再也不会请求生产者的接口了
