微服務(wù)
實踐“微服務(wù)”自然要學(xué)習(xí)如何做服務(wù)注冊與發(fā)現(xiàn)
基于SpringBoot來進行微服務(wù)的學(xué)習(xí)，自然選擇了與之息息相關(guān)的SpringCloud;當(dāng)然可以選擇其他的技術(shù)進行，比如dubbo
也可以用zookeeper來實現(xiàn)服務(wù)注冊與發(fā)現(xiàn)，至于zookeeper來實現(xiàn)此功能好還是不好，各家之言都有
SpringCloud
Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems .SpringCloud
SpringCloud 包含了 Distributed/versioned configuration、Distributed/versioned configuration等很多子項目。
- Distributed/versioned configuration
- Service registration and discovery
- Routing
- Service-to-service calls
- Load balancing
- Circuit Breakers
- Global locks
- Leadership election and cluster state
- Distributed messaging
