V ： ititit111222333

For the purpose of comprehensive technical capabilities to deal with complex businesses, we adopt a development model that separates front and back ends, strictly follow the corporate structure and specifications, and lead you to develop an enterprise media platform with three major businesses: portal platform + media center + operation center.
Through comprehensive learning of mainstream back-end technologies such as SpringCloud+Mon go DB+Redis+Rabbit MQ, you will gain comprehensive practical experience in microservices, distributed, projects and microarchitectures.
