spring boot 2.0(一)：Hello World之入门

此处省略废话，直接上操作！

第一步：使用eclipse创建Maven工程

第二步：添加依赖和代码编写

pom.xml

<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>nyfz</groupId>
  <artifactId>spring-boot-hello1</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  
    <parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.0.RELEASE</version>
	</parent>

  <dependencies>
    <dependency>
	   <groupId>org.springframework.boot</groupId>
	   <artifactId>spring-boot-starter-web</artifactId>
	</dependency>
  </dependencies>
</project>

 

HelloWorldController.java

package helloWorldController;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloWorldController {
	
	@GetMapping("/hello")
	public String hello(){
		return "hello world";
	}

}

 

启动类 AppRun.java

package helloWorldController;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class AppRun {

	public static void main(String[] args) {
		SpringApplication.run(AppRun.class, args);

	}

}

 

第三步：启动项目，测试

从启动类启动项目，RUN AS ==> Java Application

访问：http://localhost:8080/hello
