future mongodb imagination space is even greater! Therefore, Mongdb + Spring Boot is one of the best choices for data analysis in the MicroServices architecture.Let's talk about Spring Boot.Spring Boot is a new framework provided by the Pivotal team designed to simplify the

engine (no separate Web server required), the service should start on its own at the command line, and be accessed immediately through the exposed HTTP port.Concurrency: To initiate more micro-service instances to scale horizontally when demand increases.Can be arbitrarily disposed of: you can start and stop as needed.The development environment is equivalent to the production environment: minimizing the gap between all the environments in which the service runs.LOG: Use the tool to log and vie

-availability and read-write load balancing is very concise and friendly, and MongoDB comes with the concept of a replica set that can be highly available, read-write, and load balanced by designing the right set of replicas and drivers.These features of MongoDB are very handy for high-performance querying of data, and MongoDB supports Aggregate and Mapreduce using the idea of divide and conquer to handle large-scale data analysis. Spring Boot's suppo

-formed template creation that can be properly displayed by the browser, so it can also be used as a static model. You can use it to create validated XML and HTML templates. Rather than writing logic or code, developers simply add tag attributes to the template. Next, these tag properties perform pre-established logic on the DOM (Document Object model).Sample Template:You can see that thymeleaf is mainly attributed to the HTML tag, the browser when parsing the HTML, when the detection of the att
