Spring Boot boot process The Spring Boot series-5 minutes to build an app-explains how to quickly create a spring boot project and run it. Although the steps are simple and the developers save a lot of repetitive configuration work, the underlying implementation is not so simple. In this article, we'll look at the entry class Tutorialapplication to see how spring boot starts.Annotations Spring boot knows that there needs to be an entry class, which is the tutorialapplication in this example, an

providing those information.For instance, if we want to declare a spring MVC application using spring IO Platform and then we need to define lot of XML C Onfiguration like views, view resolvers etc. But if we use the Spring Boot Framework, then we dont need to define those XML Configuration. Spring Boot Autoconfigurator would take of this.If we use "Spring-boot-starter-web" JAR file with our project build file and then spring boot Autoconfigurator'll resolve Vie WS, view resolvers etc. automati

actually in the remote repository, and our project uses pom. xml configuration to specify the packages to be introduced. Step 3: rewrite App. java. When creating a Maven project, the package we specified is com. springboot. MyFirstSpringBoot. There will be an App. java in it. We will rewrite this file to the following style. package com.springboot.MyFirstSpringBoot; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org

also register the service directly by implementing the ServletContextInitializer interface. 2. After @ ServletComponentScan annotation is used on SpringBootApplication, Servlet, Filter, and Listener can be automatically registered directly through @ WebServlet, @ WebFilter, and @ WebListener annotations without additional code. Register the Servlet sample code using the code: SpringBootSampleApplication. java Package org. springboot. sample; import o

springboot based on the added jar dependency guessing how you want to configure spring,You can select automatic configuration by adding @EnableAutoConfiguration or @SpringBootApplication annotations to a @Configuration class.Note: You only need to add a @EnableAutoConfiguration note. We recommend that you add it to the main @Configuration class.If you find that you have applied specific auto-configuration classes that you do not want, you can disable
