-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

follows a very simple principle: as long as one side connects the nodes, information can be propagated and synchronized. What do you mean? Let's take a look at what happens in the following experiment. Scenario One: Let's say we have 3 registries, we'll peer1, Peer2, and Peer3 each point serviceurl to another two nodes. In other words, Peer1, Peer2 and Peer3 are 22 registered with each other. Start the three service registries and point the Compute-service serviceurl to Peer1 and start

In a microservices architecture, a service is the smallest, scalable, standalone deployment unit that can have multiple instances of the same service offering, which are registered to the Service registry (Eureka Server) for unified management and load balancing of calls.Because spring cloud is already Java as the main development language, this article will first speak the Java language of the service how to register to the service center, and then f
