As the name suggests, it is a branch of the spring framework, a sub-project, developed in 2013, and the first version was released in 2014.
Second point: What are
the benefits? Almost all web projects now use To the spring framework, it is inevitable to configure a large number of xml configuration files to use spring, and the emergence of springboot solves this problem. The purpose of spring boot is to quickly create a spring application that can run independently. Through Spring Boot, applications can be quickly created and run according to the corresponding templates. Spring Boot can automatically configure various Spring components without relying on code generation and XML configuration files . Spring Boot can greatly improve the development efficiency when using the Spring framework.
The third point: create a spring boot project
We use maven to create a simple maven+springboot project on myeclipse. The following is a screenshot of pom.
Next is the main configuration of spring boot of main. Just run the main method, you can access the url, which is springboot The real core makes it easier to create a single project, so that all spring-dependent programs can do "just run"
@SpringBootApplication
@RestController
public class App {
public static void main(String[] args) {
SpringApplication.run( App.class, args);
}
@RequestMapping("/hello")
public String hello() {
return "hello world ";
}
We run main to start this code tomcat does not need to be deployed by itself, it embeds Tomcat, Jetty Undertow itself and does not need to deploy them. After startup, visit localhost:8080/hello directly in the browser and the following hello world appears, which means the access is successful. I have no screenshots to take you into spring boot step by step for
this entry-level project. Next, I will send out my entry-level project for your reference!! !
