Spring Boot的应用启动与关闭的方法
SpringBoot，作为Spring框架对“约定优先于配置(ConventionOverConfiguration)”理念的最佳实践的产物，它能帮助我们很快捷的创建出独立运行、产品级别的基于Spring框架的应用，大部分SpringBoot应用只需要非常少的配置就可以快速运行起来，是一个与微服务(MicroServices)相当契合的微框架。
1.SpringBoot应用打包
SpringBoot应用可以打成jar包，其中内嵌tomcat，因此可以直接启动使用。但是在SpringBoot应用启动之前，首先需要进行打包，本文讲述的是Maven工程的打包，打包需要的前提条件(pom.xml文件中的内容)是：
...jar ...... org.springframework.boot spring-boot-starter-web ... org.springframework.boot spring-boot-maven-plugin com.***.Application repackage
打包命令为：
mvncleanpackage-Dmaven.test.skip=true #Demo $mvncleanpackage-Dmaven.test.skip=true [INFO]Scanningforprojects... [WARNING] [WARNING]Someproblemswereencounteredwhilebuildingtheeffectivemodelforcom.example:myproject:jar:0.0.1-SNAPSHOT [WARNING]'build.plugins.plugin.version'fororg.springframework.boot:spring-boot-maven-pluginismissing.@line38,column17 [WARNING] [WARNING]Itishighlyrecommendedtofixtheseproblemsbecausetheythreatenthestabilityofyourbuild.

或在eclipse中运行run->Mavenbuild...，在Goals中填写cleanpackage-Dmaven.test.skip=true，运行，打包完成。
2.SpringBoot应用启动
SpringBoot的启动命令为：

3.SpringBoot应用关闭
下面主要有两种方式进行SpringBoot的关闭：通过HTTP发送shutdown信号，或者通过servicestop的方式。
SpringBoot应用关闭的前提条件是POM.xml添加以下内容：
org.springframework.boot spring-boot-starter-actuator
application.properties中添加：
#启用shutdown endpoints.shutdown.enabled=true #禁用密码验证 endpoints.shutdown.sensitive=false
关闭命令为：
curl-XPOSThost:port/shutdown
#Demo
$curl-XPOSThttp://localhost:8080/shutdown
{"message":"Shuttingdown,bye..."}
$curl-XPOSThttp://localhost:8080/manage/shutdown
{"message":"Shuttingdown,bye..."}
如果要配置路径，需要在application.properties中添加management.context-path=/manage，则关闭命令变为curl-XPOSThost:port/manage/shutdown。
4.安全验证
如果在关闭时需要安全验证，则在pom.xml文件中添加：
org.springframework.boot spring-boot-starter-security
application.properties中添加：
#开启shutdown的安全验证 endpoints.shutdown.sensitive=true #验证用户名 security.user.name=admin #验证密码 security.user.password=admin #角色 management.security.role=SUPERUSER #指定端口 management.port=8081 #指定地址 management.address=127.0.0.1
关闭命令为：
curl-uadmin:admin-XPOSThttp://127.0.0.1:8081/manage/shutdown
#Demo
$curl-uadmin:admin-XPOSThttp://127.0.0.1:8081/manage/shutdown
{"message":"Shuttingdown,bye..."}
