1.创建maven项目,其中pom.xml配置依赖如下:
<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.pp</groupId>
<artifactId>springboot1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>springboot1</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<!-- 继承默认值为Spring Boot -->
<parent>
<groupId> org.springframework.boot </groupId>
<artifactId> spring-boot-starter-parent </artifactId>
<version> 2.1.4.RELEASE </version>
</parent>
<!--添加Web应用程序的典型依赖项 -->
<dependencies>
<dependency>
<groupId> org.springframework.boot </groupId>
<artifactId> spring-boot-starter-web </artifactId>
</dependency>
<!-- 热部署,开发更改代码后自动重启 -->
<dependency>
<groupId> org.springframework.boot </groupId>
<artifactId> spring-boot-devtools </artifactId>
<optional> true </optional>
</dependency>
</dependencies>
<!-- 将应用打成一个可执行的jar包 -->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
2.创建HelloWorldApplication
package com.pp.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/*
* @SpringBootApplication标注一个主程序类,说明这是一个spring boot应用
*/
@SpringBootApplication
public class HelloWordApplication {
public static void main(String[] args) {
/*
* SpringApplication.run将spring启动起来
*/
SpringApplication.run(HelloWordApplication.class, args);
}
}
3.创建controller service
package com.pp.springboot.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class HelloController {
@ResponseBody
@RequestMapping("/hello*")
public String hello() {
return "hello world 第一个spring boot程序";
}
}
4.部署
- 项目pom.xml-->Run As-->Maven install将应用打成jar包,将jar移动到指定位置(随便指定)
- 启动项目cmd -->java -jar D:\springboot1-0.0.1-SNAPSHOT.jar(其中D:\springboot1-0.0.1-SNAPSHOT.jar为jar所在位置)启动项目即可通过浏览器访问(其中即使本机没有部署tomcat也可以启动该项目,springboot自带tomcat)
5.访问
浏览器输入地址http://localhost:8080/hello之类地址即可收到回复"hello world 第一个spring boot程序"
