Static resource accessWhen we develop Web applications, we need to reference a large number of JS, CSS, pictures and other static resources.Default configurationSpring boot defaults to provide a static resource directory location to be placed under Classpath, and the directory name must conform to the following rules:/static/public/resources/meta-inf/resourcesExample: We can create a static in the src/main/resources/directory, where a picture file is

Using complex design patterns here is not worth the candle.So we have to face the plane.3. Building AOPOriginally, Spring came with a set of AOP implementations, and we used this implementation directly,

For example, if we were to introduce support for Web MVC in spring boot, we would usually introduce this module spring-boot-starter-web, which, if unpacked, would find nothing in it and only defined some pom dependencies.After study, starter is mainly used to simplify the us

I. Reading the contents of the core profile information Application.properties A core profile is a application.properties or application.yml configuration fil

Spring Cloud FeignSpring Cloud Feign is a set of declarative service invocation clients based on the Netflix feign implementation. It makes writing Web service clients easier. We only need to configure it by creating an interface and using annotations to complete the binding to the Web service interface. It features pluggable annotation support, including feign annotations, Jax-rs annotations. It also supports pluggable encoders and decoders.

Preparatory workFirst, build a simple Web project that you can use to add security controls later, or use the Chapter3-1-2 as a foundation project. If you are building a web app using spring boot, you can first read the article "Spring Boot Development web App".Web tier Implementation Request mapping@Controllerpublic c

We complete our example by creating a fully self-contained executable jar file that can be run in production env. An executable jar (sometimes called a "fat jars") is an archive file that contains the classes you compile and all the jar dependencies your code needs to run.This example continues on the basis of Spring Boot
