从零开始SpringBoot项目-入门

Posted 2020-09-21

最近项目一直用的都是SpringBoot，顺便总结一下SpringBoot的各种配置,想最简洁的运行一个SpringBoot程序，需要下面步骤

---

 

• 构建一个maven项目,项目目录结构如下

• 配置pom

  <?xml version="1.0" encoding="UTF-8"?>
  <project xmlns="http://maven.apache.org/POM/4.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
      <modelVersion>4.0.0</modelVersion>
  
      <groupId>com.blog.springboot</groupId>
      <artifactId>springboot</artifactId>
      <version>1.0-SNAPSHOT</version>
  
      <dependencyManagement>
          <dependencies>
              <dependency>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter</artifactId>
                  <version>1.3.1.RELEASE</version>
              </dependency>
          </dependencies>
      </dependencyManagement>
  
      <dependencies>
          <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-web</artifactId>
              <version>1.3.1.RELEASE</version>
          </dependency>
      </dependencies>
  
  
  </project>
  

  　

• 创建启动类                                                                                                                     

  @SpringBootApplication
  @RestController
  public class Application {
  
      public static void main(String[] args) {
          SpringApplication.run(Application.class, args);
      }
  
      @RequestMapping("/")
      public String hello() {
          return "hello world";
      }
  }
  

   

• 执行启动类中的main方法
• 浏览器输入localhost:8080

到这里，我们第一个spring程序就启动了
