总是在传统行业混,面试了几家公司。我这种独立开发者,(以前写全栈,和面试官争吵了一下子啊,hah观点不一样,会java,数据库,前端,android的简直不被看好。主要是不太精通)面试劣势。javascript
都是问一些集群,并发,大数据,分布式的东西,看来普通的java程序员混不下去了。hah。因此也学习一下吧~前端
在综合考虑对spring也是比较熟悉的状况下,想学习spring cloud,如今掀起对spring boot进行一些了解。java
spring boot就是一款spring“集团”整的一份轻量级,无配置,默认约定的快速开发框架。android
我如今学习的1.5.1.releasegit
建议使用maven进行项目管理,如今maven在java中用的应该是多的吧。maven3.2+程序员
<?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.example</groupId> <artifactId>myproject</artifactId> <version>0.0.1-SNAPSHOT</version> <!-- Inherit defaults from Spring Boot --> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.1.RELEASE</version> </parent> <!-- Add typical dependencies for a web application --> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> <!-- Package as an executable jar --> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
以上须要继承spring boot parentweb
若是不想继承,使用依赖管理面试
<dependencyManagement> <dependencies> <dependency> <!-- Import dependency management from Spring Boot --> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-dependencies</artifactId> <version>1.5.1.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>
gradle也可,2.9+,build.gradle file:spring
plugins { id 'org.springframework.boot' version '1.5.1.RELEASE' id 'java' } jar { baseName = 'myproject' version = '0.0.1-SNAPSHOT' } repositories { jcenter() } dependencies { compile("org.springframework.boot:spring-boot-starter-web") testCompile("org.springframework.boot:spring-boot-starter-test") }
咱们新建一个类数据库
package com.du; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation.ComponentScan; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController @EnableAutoConfiguration @ComponentScan public class Main { @RequestMapping("/") String home() { return "Hello World!"; } public static void main(String[] args) throws Exception { SpringApplication.run(Main.class, args); } }
run as java application,
而后打开localhost:8080便可看到Hello World!说明咱们的基础配置已经成功

小技巧:在启动后,你看到的是以下的内容
. ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: v1.5.1.RELEASE 2013-07-31 00:08:16.117 INFO 56603 --- [ main] o.s.b.s.app.SampleApplication
你能够在你的classpath中假如一个文件banner.txt
随便填写,好比hellow dim!
而后就能够看到
Hellow DIm! 2017-03-01 13:56:10.696 INFO 10332 --- [ main] com.du.Main : Starting Main on dim-PC with PID 10332 (C:\Users\Administrator\git\SpringBoot\target\classes started by Administrator in C:\Users\Administrator\git\SpringBoot)
定制本身的启动广告,hahah
