In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la

Several giant companies, Facebook and Netflix, have decided to prohibit users from executing JavaScript commands in the console (console). Initially this was started by Facebook to prevent malicious users from executing specific command-mongering messages via the JavaScript console (sending a lot of spam to all Facebook users). Of course it's a lot of blame, but before I get involved, the code they use looks like this: Copy Code code as follows:

In a microservices architecture, it is very common for a request to invoke multiple services, such as: Lower -level services can cause cascading failures if they fail.
