1、环境准备
–jdk1.8:Spring Boot 推荐jdk1.7及以上;java version "1.8.0_112"
–maven3.x:maven 3.3以上版本;Apache Maven 3.3.9
–IntelliJIDEA2017:IntelliJ IDEA 2017.2.2 x64、STS
–SpringBoot 1.5.9.RELEASE:1.5.9;
2、MAVEN设置
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile
3、创建Spring Boot HelloWorld
一个功能:浏览器发送hello请求,服务器接受请求并处理,响应Hello World字符串;
1)创建一个maven工程
2)导入spring boot相关的依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
3)编写一个主程序;启动Spring Boot应用
package com.atguigu;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @SpringBootApplication 来标注一个主程序类,说明这是一个Spring Boot应用
*/
@SpringBootApplication
public class HelloWorldMainApplication {
public static void main(String[] args) {
// Spring应用启动起来
SpringApplication.run(HelloWorldMainApplication.class,args);
}
}
4)编写相关的Controller、Service
package com.atguigu.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!";
}
}
5)运行主程序测试
6)简化部署
<!-- 这个插件,可以将应用打包成一个可执行的jar包;-->
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
执行maven的package命令
运行jar
