Getting Started with the Web-SpringBoot

Spring Boot web quick start

• Requirements: Use Spring Boot to develop a web project. After the browser initiates a request /hello, return the string "Hello World~" to the browser
• development steps
  • Create a SpringBoot project and check the relevant dependencies for web development
    • You can create modules according to the different versions of your idea
      • (Proceed to the next step after the basic information is set)
      • Select the required dependencies
        • 
  • Define the Hello Controller class, add the Hello method, and add comments
    • After the creation is complete, create a Controller class to handle the corresponding request
      • The specific code is as follows:

      • package com.example.Controller;
        
        import org.springframework.web.bind.annotation.RequestMapping;
        import org.springframework.web.bind.annotation.RestController;
        
        //请求处理类
        @RestController
        //它是@Controller的扩展，专门用于构建RESTful风格的Web服务。
        public class HelloController {
            // 设置处理的请求地址
            @RequestMapping("/hello")
            public String hello() {
                System.out.println("Hello");
                return "Hello World~";
            }
        }
        

  • Run the SpringBoot startup class to test the running results
    • The result of the operation is as follows:
    • (Web side)
    • (idea end)
• As a java development framework, SpringBoot is essentially a java application. It has built-in many common configurations and default settings, which reduces the workload of developers on project configuration and makes the development process easier and more efficient.
