【demo】新建一个springboot项目最简单的方法

springboot可以极大的加速一个项目的开发，看下面的例子

首先建一个快速启动的maven项目，然后修改pom.xml，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>springboot</groupId>
<artifactId>web</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>web</name>
<url>http://maven.apache.org</url>

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.4.RELEASE</version>
<relativePath /> <!-- lookup parent from repository -->
</parent>

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.7</java.version>
</properties>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>springloaded</artifactId>
<version>1.2.5.RELEASE</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
</project>


然后写一个类,写上如下代码
package springbootdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
*
* @author qq1623299667
*
*/
@SpringBootApplication
public class Application {

public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

}


现在就OK了，想出现一个页面
再写一个类

package springbootdemo.web;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
*
* @author qq1623299667
*
*/
@RestController
public class Controller {
@RequestMapping("/now")
String getTime(){
SimpleDateFormat sdf = new SimpleDateFormat("YYYYMMddHHmmssSSS");
return sdf.format(new Date());
}

@RequestMapping("/")
String welcome(){
return "你好！";
}
}


这样在浏览器地址栏输入localhost:8080的时候就可以看到服务器的提示，也可以输入localhost:8080/now获取一串当前时间组成的字符串，够简单吧！
