1. pom 文件的依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.2.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

添加如下插件信息，会使得 idea 的 maven 工具提供 spring-boot 的构建选项：

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

2. main 类

@SpringBootApplication
@RestController
@RequestMapping("/hello")
public class DemoApplication {

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

    @RequestMapping(value = "/{firstName}/{lastName}",
            method = RequestMethod.GET)
    public String hello(@PathVariable("firstName") String firstName,
                        @PathVariable("lastName") String lastName){

        return String.format("{\"message\": \"hello %s %s\"}",
                firstName, lastName);
    }
}
