I. Spring boot history backgroundSpring was born as a lightweight alternative to the Java Enterprise Edition (Java Business Edition,jee, also known as EE). Without the development of heavyweight Enterprise JavaBean (EJB), Spring provides a relatively simple way for enterprise Java development, with dependency injection and aspect-oriented programming, with simple

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 Impl

Spring boot attracts a lot of fans with its many features of friendship, such as 0 configuration and microservices. and its seamless integration with the Spring security framework makes it a secure feature. On this basis, using the Thymeleaf template engine for rendering, static and dynamic combination, so that the page development more simple and intuitive.The u

whole business, it is some log or other auxiliary code. And many businesses need the same functionality, such as the need to log, it is necessary to copy the functions of these logging, even if it is packaged into a framework, but also need to call. 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,

The company uses spring cloud, so take a little lookTake a look at Spring's website's explanation of spring boot and spring cloudSpring BootSpring Boot makes it easy to create stand-alone, Production-grade Spring based application

Spring Boot creates beans using Java code and registers them to Spring. From Spring3.0, a new method is added to configure Bean Definition, which is to configure Bean Definition through Java Code.The two configuration methods differ from Xml and Annotation: The first two Xml and Annotation configuration methods are pre-defined, that is, after developers use the X

The package name is demo by default and the project name is demo by default.2. Directory structureRegardless of the way we create a project, after importing the project into the IDE, we can see that the entire project structure follows the layout of a traditional Maven or Gradle p
