SpringBoot （一）环境搭建

环境 ：

jdk1.7  

myeclipse2014

springboot

springboot 官网指南：https://spring.io/guides/gs/spring-boot/

1、使用maven构建java project

2、修改pom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">  <modelVersion>4.0.0</modelVersion>  <groupId>com.zxl.test</groupId>  <artifactId>springboot-increase</artifactId>  <version>1.0</version>  <packaging>jar</packaging>  <name>springboot-increase</name>  <url>http://maven.apache.org</url>   <parent>       <groupId>org.springframework.boot</groupId>       <artifactId>spring-boot-starter-parent</artifactId>       <version>1.5.8.RELEASE</version>   </parent>  <properties>    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>  </properties>  <dependencies>    <dependency>      <groupId>junit</groupId>      <artifactId>junit</artifactId>      <version>3.8.1</version>      <scope>test</scope>    </dependency>    <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>    </dependency>  </dependencies></project>

主要是添加红色部分的内容。

3、创建Controller类HelloController

package hello;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class HelloController {@RequestMapping("/")public String index(){return "Hello World!";}}

4、创建启动类Application

package hello;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationContext;@SpringBootApplicationpublic class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);}}

5、文档结构如下所示：

6、启动Application

Application.java文件上右键 run as  --》 java application

控制台输出如下：

7、打开浏览器，输入 localhost:8080，页面显示Hello World
