Spring Boot Hello and docker

The main is to try the spring boot run in the Docker feel, small test sledgehammer:)

This is the original text, refer to: https://spring.io/guides/gs/spring-boot-docker/

1. Environment

Win10, Eclipse, MVN, CentOS 7.3 (VM), Docker 1.12

That is, the development environment under WIN10, Docker environment in the CentOS VM

2. Project diagram

Two code files: Application.java, Hellocontroller.java

A dockerfile to build the jar into a mirror

A pom.xml, this does not explain

3. Source Files:

Application.java

 Package Ex.springbootdocker; Import org.springframework.boot.SpringApplication; Import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication  Public class Application {    publicstaticvoid  main (string[] args) {        Springapplication.run (Application. class , args);}    }

Hellocontroller.java

 PackageEx.springbootdocker;Importorg.springframework.web.bind.annotation.PathVariable;Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RequestMethod;ImportOrg.springframework.web.bind.annotation.RestController; @RestController Public classHellocontroller {@RequestMapping (value= "/hello/{name}", method=requestmethod.get) PublicString SayHello (@PathVariable ("name") (String name) {return"Hello," +name; }}

Dockerfile

From openjdk:8-jdk-/tmpadd ex.springbootdocker-0.0.1. jar app.jarenv java_opts= ""  -jar/app.jar

4. Description

1). My eclipse does not automatically generate jars, only mvn the package

2). Copy the generated jar and Dockerfile to the CentOS VM, e.g./opt/docker

3). Create image

4). Run
