Spring cloud itself provides a lot of components, but we need to follow the business model to customize the enterprise needs of the common architecture, then we need to consider what technology to use now?Below I have made the following technical summary for the spring Cloud Micro-service distributed cloud architecture, hoping to help you:View:H5, Vue.js, Spring Tag, React, AngularJsSpring boot/spring Cloud:Zuul, Ribbon, feign, Turbine, Hystrix, Oauthor2, Sleuth, API Gateway, Spring Cloud, Confi

We can see from the console of the eureka-client that the service provider outputs the results that were originally to be returned, but because the service consumer triggered a service request timeout exception due to a delay of 5 seconds before it was returned, the service consumer was executed by the downgrade logic specified in th

Click Next to enter the last few details about the physical storage of the project. Finally, click Finish to complete the construction of the project. IntelliJ Spring Initializr is still based on the official web implementation, but the tool makes calls and builds the results directly into our local file system, making the entire build process smoother, withou

-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
