一.基本信息
源码仓库:https://github.com/spring-projects/spring-boot
帮助文档:https://spring.io/guides/gs/spring-boot/
二.快速开始
1.通过maven创建一个工程
mvn archetype:generate -DgroupId=com.hippo -DartifactId=AppDemo -DarchetypeArtifactId=maven-archetype-webapp
2.创建一个package包目录
mkdir -p src/main/java/hello
3.配置一下pom.xml
<?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.hippo</groupId>
<artifactId>AppDemo</artifactId>
<version>0.1.0</version>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.8.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<properties>
<java.version>1.8</java.version>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
4.创建一个contrller文件
touch src/main/java/hello/HelloController.java
package hello;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@RestController
public class HelloController {
@RequestMapping("/")
public String index() {
return "Greetings from Spring Boot!";
}
}
5. 创建一个Application 启动文件
touch src/main/java/hello/Application.java
package hello;
import java.util.Arrays;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
6.启动
mvn package && java -jar target/AppDemo.jar
7.访问
$ curl localhost:8080 Greetings from Spring Boot!
