Docker部署Spring-boot项目的示例代码

一、基础Spring-boot快速启动

 1.1 快速启动 pom.xml加入如下依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.5.RELEASE</version>
  </parent>
  <properties>
    <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <finalName>spring-docker</finalName>
    <plugins>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
    </plugins>
  </build>

Spring-boot启动类

@SpringBootApplication
public class DockerApplication {
  public static void main(String[] args) {
    SpringApplication.run(DockerApplication.class, args);
  }
}

测试API

@RestController
public class DockerStarterApi {
  @GetMapping("/api/docker/hello")
  public String hello() {
    return "hello docker";
  }
}

配置启动配置文件

application.yml

server:
 port: 9090 # 为了展示效果, 这里改了默认端口8080

检查Spring启动
