Apache Dubbo Component

Java SDK (apache/dubbo)

Details

In the spring environment, dubbo's default registration behavior may register with the registration center before the beans it depends on and their resources are initialized. This will cause errors when some requests come in. At this time, the provider is actually unavailable. To solve this problem, automatic registration is generally turned off and then health checks are performed through scripts. After passing the health check, use qos to go online. However, this behavior can be implemented in the program using healthEndpoint.health(). I think such a function should be provided to users rather than being implemented entirely through operation and maintenance means.
