discovery模块

spring-cloud-consul-discovery模块下实际有 serviceregistry 和 discovery 两大块。

自动装配

META-INF/spring.factories 的内容:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
org.springframework.cloud.consul.discovery.RibbonConsulAutoConfiguration,\
org.springframework.cloud.consul.discovery.configclient.ConsulConfigServerAutoConfiguration,\
org.springframework.cloud.consul.serviceregistry.ConsulAutoServiceRegistrationAutoConfiguration,\
org.springframework.cloud.consul.serviceregistry.ConsulServiceRegistryAutoConfiguration

# Discovery Client Configuration
org.springframework.cloud.client.discovery.EnableDiscoveryClient=\
org.springframework.cloud.consul.discovery.ConsulDiscoveryClientConfiguration

org.springframework.cloud.bootstrap.BootstrapConfiguration=\
org.springframework.cloud.consul.discovery.configclient.ConsulDiscoveryClientConfigServiceBootstrapConfiguration

需要自动装配的内容有：

• discovery.RibbonConsulAutoConfiguration： 给ribbon用的
• discovery.ConsulConfigServerAutoConfiguration
• serviceregistry.ConsulAutoServiceRegistrationAutoConfiguration
• serviceregistry.ConsulServiceRegistryAutoConfiguration

然后还有定义的 Discovery Client Configuration：

• ConsulDiscoveryClientConfiguration
• ConsulDiscoveryClientConfigServiceBootstrapConfiguration
