Springboot 簡單入門

一、創建maven 項目

二、修改 pom.xml 文件

<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">
	<!-- 項目信息 -->
	<modelVersion>4.0.0</modelVersion>
	<groupId>com.csdn</groupId>
	<artifactId>springbootDemo</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<!-- 項目信息 -->
	<!-- 版本信息 -->
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.9.RELEASE</version>
		<relativePath />
	</parent>
	<!-- 版本信息 -->
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>
	<!-- 版本信息 -->
	<!-- 項目依賴 -->
	<dependencies>
		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
	</dependencies>
	<!-- 項目依賴 -->
</project>

三、創建

springboot 啓動入口 SpringbootApplication.java 

package com.csdn;

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

@SpringBootApplication
public class SpringbootApplication {

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

四、創建application.yml 全局配置文件

五、創建controller 測試

package com.csdn.action;

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

@RestController
public class TestSpringboot {
	
	@GetMapping("/say")
	public String say(){
		return "Hello world";
	}
}
