When you want to change, add the annotation @cacheput in the updated section (cachenames = "blog", key= "123")Use annotation @cacheevict (cachenames = "blog", key= "123") to clear the cache when the object type to be written is not the sameBlog2.0--springboot Add

Traditional software services architecture is generally single-node, as long as the single node has an outage, and often a lot of services are not downtime, especially in the era of mobile internet, the availability of many applications are required to maintain the availability of 99.99....%. This requires that our services must be distributed, preferably at the same time load balancing, failover, and dynamic expansion, which is the problem to be solved in this paper.Architecture Design:650) thi

Stackexchang has 4 million users, with 0.56 billion PV per month, but only 25 servers are used, and the CPU load is not high.It does not use cloud computing, because cloud computing may slow down, making it more difficult to optimize and eliminate system faults.Stackoverflow still uses Microsoft's architecture.
