Spring Boot,作为Spring框架对“约定优先于配置(Convention Over Configuration)”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Spring Boot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. Spring Boot应用打包
Spring Boot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Spring Boot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:

3. Spring Boot应用关闭
下面主要有两种方式进行Spring Boot的关闭:通过HTTP发送shutdown信号,或者通过service stop的方式。
Spring Boot应用关闭的前提条件是POM.xml添加以下内容:
1
2
3
4
|
< dependency >
< groupId >org.springframework.boot</ groupId >
< artifactId >spring-boot-starter-actuator</ artifactId >
</ dependency >
|
application.properties中添加:
1
2
3
4
|
#启用shutdown
endpoints.shutdown.enabled=true
#禁用密码验证
endpoints.shutdown.sensitive=false
|
关闭命令为:
1
2
3
4
5
6
|
curl -X POST host:port /shutdown
# Demo
$ curl -X POST http: //localhost :8080 /shutdown
{ "message" : "Shutting down, bye..." }
$ curl -X POST http: //localhost :8080 /manage/shutdown
{ "message" : "Shutting down, 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 -X POST host: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:
1
2
3
4
|
< dependency >
< groupId >org.springframework.boot</ groupId >
< artifactId >spring-boot-starter-security</ artifactId >
</ dependency >
|
application.properties中添加:
1
2
3
4
5
6
7
8
9
10
11
12
|
#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:
1
2
3
4
|
curl -u admin:admin -X POST http: //127 .0.0.1:8081 /manage/shutdown
# Demo
$ curl -u admin:admin -X POST http: //127 .0.0.1:8081 /manage/shutdown
{ "message" : "Shutting down, bye..." }
|
