import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@SpringBootApplication
@Configuration
public class HelloApplication {
@RequestMapping("hello")
@ResponseBody
public String hello() {
return "hello world！";
}
public static void main(String[] args) {
// 运行的类必须包含@SpringBootApplication
SpringApplication.run(HelloApplication.class, args);
}
}

1.5 将项目打包
2 Docker部署SpringBoot项目
2.1 编辑 Dockerfile
# 切换到该目录
[root@localhost boot]# pwd
/usr/local/gp6/boot
# 编辑 Dockerfile
[root@localhost boot]# vi Dockerfile
FROM openjdk:8
MAINTAINER gp6 <gp6@test.com>
# VOLUME 指定了临时文件目录为/tmp。
# 其效果是在主机 /var/lib/docker 目录下创建了一个临时文件，并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为docker-boot.jar
ADD SpringBoot-1.0-SNAPSHOT.jar docker-boot.jar
# 运行jar包
RUN bash -c 'touch /docker-boot.jar'
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/docker-boot.jar"]
2.2 将SpringBoot-1.0-SNAPSHOT.jar包传入/usr/local/gp6/boot
2.3 制作镜像
[root@localhost boot]# docker build -t docker-boot .
Sending build context to Docker daemon 16.62MB

2.4 启动容器
[root@localhost ~]# docker run -di --name dockerBoot -p 8080:8080 docker-boot

2.5 宿主机测试
# 宿主机测试
[root@localhost ~]# curl 127.0.0.1:8080/hello
hello world！
2.6 浏览器测试
http://宿主机IP:8080/hello
测试
