提取公共 API 到单独的模块中

@RequestMapping("/refactor")
public interface IHelloService {

    @GetMapping("/hello3")
    String hello(@RequestParam(value = "name") String name);

    @GetMapping("/hello4")
    String hello(@RequestHeader("name") String name, @RequestHeader(value = "age") Integer age);
}

pom.xml 配置

打包之前使用了 spring-boot-maven-plugin 插件，去掉后打包正常
