apache-dubbo-2.7.3
2.7.3
Compatibility
In order to unify the implementation of service governance rules in different configuration centers, such as Zookeeper, Nacos, Etcd, etc., we have refactored some implementations of the configuration center compared to 2.7.0~2.7.2.
- For users who are using 2.7.x service governance rules, please check the new implementation before upgrading to 2.7.3, make sure all rules have a copy under the new storage path to ensure a smooth upgrade.
- For users who have upgraded the 2.7.x version but are not using any service governance rules, you can upgrade directly.
- For users using 2.6.x and lower versions can upgrade directly. But make sure you follow the following instructions Upgrading from 2.6.x to 2.7.x
Change List
-
Asynchronous support
-
Configuration Center
- ConfigCenter custom namespace does not take effect, #4411
- Unify the models implemented by several configuration centers such as Zookeeper, Nacos, and Etcd. Please refer to the description for possible incompatibility issues, #4441
- Adjust Override Coverage Rule Center Priority: Service Level > Application Level, #4175.
-
2.6.x compatibility
-
The Nacos Registration Center only subscribes to the address list and no longer subscribes to configuration information, #4454.
-
Support to read the environment configuration from the specified location, which can be specified by -D or OS VARIABLE. Please refer to automatically loading environment variables
升级注意事项
为了统一不同配置中心(如Zookeeper、Nacos、Etcd等)对于服务治理规则的实现,我们对2.7.0以来的配置中心的部分实现进行了重构。
- 对于已使用了2.7.x新版本服务治理规则的用户,升级2.7.3之前请先查看新版实现,确保已有规则在新路径下已经存在拷贝,以确保平滑升级。
- 对于已经升级了2.7.x版本,但是未使用服务治理规则的用户,此次升级不受影响。
- 对于2.6.x及以下版本用户不受此次变更影响,升级步骤请参见升级到2.7.x的说明文档。

apache-dubbo-2.7.1
Warning: According to reports from the community, be aware of possible Service Discovery problems in certain circumstances. Check #4213 for details.
风险提示:升级到2.7.1版本后,注册中心(多数是zookeeper)在某些特殊场景下会出现重复URL地址数据无法删除,导致消费方拿到的是失效地址,从而导致调用失败的问题,2.7.2版本里面会修复此问题,预计6月初发布。详细原因请参考#4213。
Notice
'zkclient' extension for 'org.apache.dubbo.remoting.zookeeper.ZookeeperTransporter' is removed from Dubbo 2.7.1, and 'curator' extension becomes the default extension. If you happen to config your application to use 'zkclient' explicitly, pls. switch to use 'curator' instead.

apache-dubbo-2.7.0
2.7.0
Requirements: Java 8+ required
Please check here for notes and possible compatibility issues for upgrading from 2.6.x or lower to 2.7.0.
New Features
-
Enhancement of service governance rules.
- Enriched Routing Rules.
- Conditional Routing. Supports both application-level and service-level conditions.
- Tag Routing. Newly introduced to better support traffic isolation, such as grey deployment.
- Decoupling governance rules with the registry, making it easier to extend. Apollo and Zookeeper are available in this version. Nacos support is on the way...
- Application-level Dynamic Configuration support.
- Use YAML as the configuration language, which is more friendly to read and use.
- Enriched Routing Rules.
-
Externalized Configuration. Supports reading
dubbo.properties
hosted in remote centralized configuration center - centralized configuration. -
Simplified registry URL. With lower Registry memory use and less notification pressure from Service Directory, separates Configuration notification from Service Discovery.
-
Metadata Center. A totally new concept since 2.7.0, used to store service metadata including static configuration, service definition, method signature, etc.. By default, Zookeeper and Redis are supported as the backend storage. Will work as the basis of service testing, mock and other service governance features going to be supported in OPS.
-
Asynchronous Programming Model (only works for Dubbo protocol now)
- Built-in support for the method with CompletableFuture signature.
- Server-side asynchronous support, with an AsyncContext API works like Servlet 3.0.
- Asynchronous filter chain callback.
-
Serialization Extension: Protobuf.
-
Caching Policy Extension: Expiring Cache.
Enhancements / Bugfixes
-
Load Balancing strategy enhancement: ConsitentHash #2190, LeastActive #2171, Random #2597, RoundRobin #2650.
-
Third-party dependency upgrading.
- Switch default remoting to Netty 4.
- Switch default Zookeeper client to Curator.
- Upgrade Jetty to 9.x.
-
IPV6 support #2079.
-
Performance tuning, check hanging requests on a closed channel, make them return directly #2185.
-
Fixed the serialization problem of JDK primitive types in Kryo #2178.
-
Fixed the problem of failing to notify Consumer as early as possible after the Provider side deserialization failed #1903.
Upgrading and Compatibility Notifications
We have always keep compatibility in mind during the whole process of 2.7.0. We even want old users to upgrade with only on pom version upgrade, but it's hard to achieve that, especially when considering that we have the package renamed in this version, so we had some tradeoffs. If you only used the Dubbo's most basic features, you may have little problems of upgrading, but if you have used some advanced features or have some SPI extensions inside, you'd better read the upgrade notifications carefully. The compatibility issues can be classified into the following 5 categories, for each part, you can find the detailed dos and don'ts in this documentation.
-
Interoperability between 2.7.0 and lower versions
-
Package renaming
com.alibaba.dubbo -> org.apache.dubbo
-
Simplification of registered URLs
-
Service Governance Rules
-
Configuration
环境要求:需要Java 8及以上版本支持
请在这里了解关于升级2.7.x版本的注意事项和兼容性问题
New Features

服务治理规则增强。
-
外部化配置。支持读取托管在远程的集中式配置中心的dubbo.properties,实现应用配置的集中式管控。

-
新增服务元数据中心,负责存储包括服务静态化配置、服务定义(如方法签名)等数据,默认提供Zookeeper, Redis支持。此功能也是OPS实现服务测试、Mock等治理能力的基础。
-
异步编程模式增强(限定于Dubbo协议)
- 原生CompletableFuture签名接口支持

升级与兼容性
此次版本发布我们遵循了保持和老版本兼容的原则,尤其是在保证与低版本互操作性的问题上,2.7.0版本是能做到完全兼容的。对于2.7.0的默认行为,最容易带来兼容性问题的此次发布版本内容中的package重命名,但这类问题是显示的,即能在升级后的编译期发现并予以解决。了解更多升级和兼容性注意事项。
