配置pom.xml

官方网址有相关配置，本文采用1.5.1版本的，完整pom
注意，如果要打成可执行jar包，要指定jar包的主函数

编写测试java类

package com.pzr.consumer.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * 官方例子
 * @author pzr
 *
 */
@Controller
@EnableAutoConfiguration
public class OfficialDemo {
    @RequestMapping("/test")
    @ResponseBody
    String home() {
        return "Hello World!";
    }

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