"Problem description"One of the most serious resource problems in using Spring cloud is the high memory footprint, and the fact that there is not a large amount of development testing, or even a problem with the service not being properly accessed."Cause analysis"The main reason is that when a single micro-service from spring Cloud is deployed on a Linux system server, the memory consumed on a Linux system computer with 8G of memory reaches around 1G. With only 5 or so micro services deployed, t

After we have completed the implementation of the service content, we will continue to application.properties do some configuration work, as follows:

spring.application.name=eureka-clientserver.port=2001eureka.client.serviceurl.defaultzone=http://localhost:1001/eureka/
By using spring.application.name properties, we can specify that the name of the microservices will follow

Micro-Service Authorization verification
To run a license plate, buy a house and other life, in the harmonious big China and foreign countries, all need a variety of certificates. depend on each other.
Similar authorization certifications should be provided in the MicroServices world. This is a safe line of defense.

"monomer" applications, but more on the "vertical layering" of the overall business. Regardless of the horizontal or vertical points, the essence of "points" is actually because of "heavy". "Divide and conquer" should be regarded as the most basic human thinking logic. But the concrete realization of the "points" is also attributed to the question of what is standing on our opposite side. The internet is the main thrust of the "business" from the offline to the line, in the initial development
