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

) Execution java -jar xxx.jar --spring.profiles.active=prod , you can observe that the service port is set to 3333 , that is, the configuration of the production environment (PROD) According to the above experiment, we can summarize the multi-environment configuration ideas as follows: application.propertiesThe common content is configured in and set to the spring.profiles.active=dev development environment as the default configuration application-{profile}.properti

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

Applicationmaster.java,applicationbackup.javaThe contents of the code are the same @EnableEurekaServer @SpringBootApplication public class ApplicationMaster { public static void main(String[] args) { SpringApplication.run(ApplicationMaster.class, args); } } @EnableEurekaServer @SpringBootApplication public class ApplicationBackUp { public static void main(String[] args) { SpringApplication.run(ApplicationBackUp.class, args);

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

be executed sequentially based on the value returned by the method. shouldFilter: Determines whether the filter needs to be executed. Here we return directly true , so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter. run: The specific logic of the filter. Here we ctx.setSendZuulResponse(false) can further optimize our return by making Zuul filter the request, not routing it, and then by ctx.setResponseStatus

return true, so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.Run: The specific logic of the filter. Here we use Ctx.setsendzuulresponse (false) to make Zuul filter the request, do not route it, and then set its return error code via CTX.SETRESPONSESTATUSCODE (401). Of course, we can also further optimize our return, for example, by Ctx.setresponsebody (body) to return the body content to edit and so on.After impl

BEA unveiled its Infrastructure software optimization plan on 19th to cater to the service-oriented Architecture (SOA) adopted by enterprise customers. The company's three main product lines-aqualogic, WebLogic and tuxedo-will eventually use the same software base, called "MicroServices architecture". The Service Oriented ar
