本文主要演示如何使用Spring Boot加速应用开发的。你可以访问,快速构建属于你自己的基于Spring Boot的应用。如图，一键即可生成项目。1.开始构建项目1.1)项目结构1.2 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&org.springframework&/groupId&
&&&&&artifactId&gs-spring-boot&/artifactId&
&&&&&version&0.1.0&/version&
&&&&&parent&
&&&&&&&&&groupId&org.springframework.boot&/groupId&
&&&&&&&&&artifactId&spring-boot-starter-parent&/artifactId&
&&&&&&&&&version&1.3.5.RELEASE&/version&
&&&&&/parent&
&&&&&dependencies&
&&&&&&&&&dependency&

&&&&&&&&&plugins&
&&&&&&&&&&&&&plugin&

&&&&&&&&&&&&&&&&&artifactId&spring-boot-maven-plugin&/artifactId&
&&&&&&&&&&&&&/plugin&
&&&&&&&&&/plugins&
&&&&&/build&&/project&提供以下支持：1.收集classpath下的jar，作为单个可运行的“über-jar”，这样可以更适合传输和执行。2.搜索public static void main()，标记为可运行的class3.提供内置依赖管理（Spring Boot dependencies.）1.3 使用spring boot能做什么？它提供快速构建应用的方式，搜索classpath和配置的bean,可以帮你从基础工作冲解脱出来，专心实现业务。1.使用springmvc?提供了几个bean,spring会自动加入；spring需要servlet容器支持，spring自动配置内嵌的tomcat。2.使用 jetty?不想使用tomcat,spring很容易进行切换3.Thymeleaf?也提供了支持。Thymeleaf 如果在classpath下，spring会自动加入SpringTemplateEngine 这仅仅是几个自动配置的场景。spring boot不会生成代码或修改你的文件，它会动态扩展bean和配置，并在应用中使用他们。1.4 创建一个简单的web应用package&
import&org.springframework.web.bind.annotation.RestC
import&org.springframework.web.bind.annotation.RequestM
@RestController
public&class&HelloController&{
&&&&@RequestMapping("/")
&&&&public&String&index()&{
&&&&&&&&return&"Greetings&from&Spring&Boot!";
}@RestController表示类准备使用SpringMVC处理web请求，绑定了@Controller和@ResponseBodypackage&org.springframework.web.bind.
@java.lang.annotation.Target({java.lang.annotation.ElementType.TYPE})
@java.lang.annotation.Retention(java.lang.annotation.RetentionPolicy.RUNTIME)
@java.lang.annotation.Documented
@org.springframework.stereotype.Controller
@org.springframework.web.bind.annotation.ResponseBody
public&@interface&RestController&{
&&&&java.lang.String&value()&default&"";
}1.5创建一个应用Classpackage&
import&java.util.A
import&org.springframework.boot.SpringA
import&org.springframework.boot.autoconfigure.SpringBootA
import&org.springframework.context.ApplicationC
@SpringBootApplication
public&class&Application&{
&&&&public&static&void&main(String[]&args)&{
&&&&&&&&ApplicationContext&ctx&=&SpringApplication.run(Application.class,&args);
&&&&&&&&System.out.println("Let's&inspect&the&beans&provided&by&Spring&Boot:");
&&&&&&&&String[]&beanNames&=&ctx.getBeanDefinitionNames();
&&&&&&&&Arrays.sort(beanNames);
&&&&&&&&for&(String&beanName&:&beanNames)&{
&&&&&&&&&&&&System.out.println(beanName);
}@SpringBootApplication 也是1个组合体@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Configuration
@EnableAutoConfiguration
@ComponentScan
public&@interface&SpringBootApplication{
}@ComponentScan:告诉spring boot查找其他的components,configurations,services @EnableAutoConfiguration ：告诉spring boot基于classpath添加bean,settings。一般情况下，你需要添加@EnableWebMvc，但spring boot在classpath中发现&spring-webmvc ，会自动添加@EnableWebMvc；SpringApplication.run() 启动应用入口，没有web.xml,没有application.xml.100%的java.输出结果如下D:\Java\jdk1.7.0_65\bin\java&-Didea.launcher.port=7535&"-Didea.launcher.bin.path=D:\Program&Files&(x86)\JetBrains\IntelliJ&IDEA&14.1.4\bin"&-Dfile.encoding=UTF-8&-classpath&"D:\Java\jdk1.7.0_65\jre\lib\charsets.D:\Java\jdk1.7.0_65\jre\lib\deploy.D:\Java\jdk1.7.0_65\jre\lib\javaws.D:\Java\jdk1.7.0_65\jre\lib\jce.D:\Java\jdk1.7.0_65\jre\lib\jfr.D:\Java\jdk1.7.0_65\jre\lib\jfxrt.D:\Java\jdk1.7.0_65\jre\lib\jsse.D:\Java\jdk1.7.0_65\jre\lib\management-agent.D:\Java\jdk1.7.0_65\jre\lib\plugin.D:\Java\jdk1.7.0_65\jre\lib\resources.D:\Java\jdk1.7.0_65\jre\lib\rt.D:\Java\jdk1.7.0_65\jre\lib\ext\access-bridge-64.D:\Java\jdk1.7.0_65\jre\lib\ext\dnsns.D:\Java\jdk1.7.0_65\jre\lib\ext\jaccess.D:\Java\jdk1.7.0_65\jre\lib\ext\localedata.D:\Java\jdk1.7.0_65\jre\lib\ext\sunec.D:\Java\jdk1.7.0_65\jre\lib\ext\sunjce_provider.D:\Java\jdk1.7.0_65\jre\lib\ext\sunmscapi.D:\Java\jdk1.7.0_65\jre\lib\ext\zipfs.E:\open\apache\spring-boot-example\target\D:\Documents\.m2\repository\org\thymeleaf\thymeleaf\2.1.4.RELEASE\thymeleaf-2.1.4.RELEASE.D:\Documents\.m2\repository\ognl\ognl\3.0.8\ognl-3.0.8.D:\Documents\.m2\repository\org\javassist\javassist\3.18.1-GA\javassist-3.18.1-GA.D:\Documents\.m2\repository\org\unbescape\unbescape\1.1.0.RELEASE\unbescape-1.1.0.RELEASE.D:\Documents\.m2\repository\org\slf4j\slf4j-api\1.7.21\slf4j-api-1.7.21.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-starter-web\1.3.5.RELEASE\spring-boot-starter-web-1.3.5.RELEASE.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-starter\1.3.5.RELEASE\spring-boot-starter-1.3.5.RELEASE.D:\Documents\.m2\repository\org\springframework\boot\spring-boot\1.3.5.RELEASE\spring-boot-1.3.5.RELEASE.D:\Documents\.m2\repository\org\springframework\spring-core\4.2.6.RELEASE\spring-core-4.2.6.RELEASE.D:\Documents\.m2\repository\org\springframework\spring-context\4.2.6.RELEASE\spring-context-4.2.6.RELEASE.D:\Documents\.m2\repository\org\springframework\spring-aop\4.2.6.RELEASE\spring-aop-4.2.6.RELEASE.D:\Documents\.m2\repository\aopalliance\aopalliance\1.0\aopalliance-1.0.D:\Documents\.m2\repository\org\springframework\spring-beans\4.2.6.RELEASE\spring-beans-4.2.6.RELEASE.D:\Documents\.m2\repository\org\springframework\spring-expression\4.2.6.RELEASE\spring-expression-4.2.6.RELEASE.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-autoconfigure\1.3.5.RELEASE\spring-boot-autoconfigure-1.3.5.RELEASE.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-starter-logging\1.3.5.RELEASE\spring-boot-starter-logging-1.3.5.RELEASE.D:\Documents\.m2\repository\ch\qos\logback\logback-classic\1.1.7\logback-classic-1.1.7.D:\Documents\.m2\repository\ch\qos\logback\logback-core\1.1.7\logback-core-1.1.7.D:\Documents\.m2\repository\org\slf4j\jcl-over-slf4j\1.7.21\jcl-over-slf4j-1.7.21.D:\Documents\.m2\repository\org\slf4j\jul-to-slf4j\1.7.21\jul-to-slf4j-1.7.21.D:\Documents\.m2\repository\org\slf4j\log4j-over-slf4j\1.7.21\log4j-over-slf4j-1.7.21.D:\Documents\.m2\repository\org\yaml\snakeyaml\1.16\snakeyaml-1.16.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-starter-tomcat\1.3.5.RELEASE\spring-boot-starter-tomcat-1.3.5.RELEASE.D:\Documents\.m2\repository\org\apache\tomcat\embed\tomcat-embed-core\8.0.33\tomcat-embed-core-8.0.33.D:\Documents\.m2\repository\org\apache\tomcat\embed\tomcat-embed-el\8.0.33\tomcat-embed-el-8.0.33.D:\Documents\.m2\repository\org\apache\tomcat\embed\tomcat-embed-logging-juli\8.0.33\tomcat-embed-logging-juli-8.0.33.D:\Documents\.m2\repository\org\apache\tomcat\embed\tomcat-embed-websocket\8.0.33\tomcat-embed-websocket-8.0.33.D:\Documents\.m2\repository\org\springframework\boot\spring-boot-starter-validation\1.3.5.RELEASE\spring-boot-starter-validation-1.3.5.RELEASE.D:\Documents\.m2\repository\org\hibernate\hibernate-validator\5.2.4.Final\hibernate-validator-5.2.4.Final.D:\Documents\.m2\repository\javax\validation\validation-api\1.1.0.Final\validation-api-1.1.0.Final.D:\Documents\.m2\repository\org\jboss\logging\jboss-logging\3.3.0.Final\jboss-logging-3.3.0.Final.D:\Documents\.m2\repository\com\fasterxml\classmate\1.1.0\classmate-1.1.0.D:\Documents\.m2\repository\com\fasterxml\jackson\core\jackson-databind\2.6.6\jackson-databind-2.6.6.D:\Documents\.m2\repository\com\fasterxml\jackson\core\jackson-annotations\2.6.6\jackson-annotations-2.6.6.D:\Documents\.m2\repository\com\fasterxml\jackson\core\jackson-core\2.6.6\jackson-core-2.6.6.D:\Documents\.m2\repository\org\springframework\spring-web\4.2.6.RELEASE\spring-web-4.2.6.RELEASE.D:\Documents\.m2\repository\org\springframework\spring-webmvc\4.2.6.RELEASE\spring-webmvc-4.2.6.RELEASE.D:\Program&Files&(x86)\JetBrains\IntelliJ&IDEA&14.1.4\lib\idea_rt.jar"&com.intellij.rt.execution.application.AppMain&hello.Application&--spring.output.ansi.enabled=always
