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;

@RestController
public 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;

@SpringBootApplication
public 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
