我这里是根据上面博主的文章做的练习

一、新建模块

二、编写starter

DemoService：

package com.gc;

public class DemoService {
    private String demo;
    public DemoService(String demo){
        this.demo = demo;
    }

    @Override
    public String toString() {
        return "DemoService{" +
                "demo='" + demo + '\'' +
                '}';
    }
}

DemoConfig：

package com.gc;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@ConfigurationProperties(prefix = "hh")
public class DemoConfig {
    private String demo;

    @Bean
    public DemoService demoService(){
        return new DemoService(demo);
    }

    public String getDemo() {
        return demo;
    }

    public void setDemo(String demo) {
        this.demo = demo;
    }
}

Spring.factories：

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.gc.DemoConfig

安装到maven仓库

三、引入自定义starter测试

在application.properties中添加配置：

hh.demo=123

启动类测试：

package com.gc;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

@SpringBootApplication
public class UserApplication {
    public static void main(String[] args) {
        ConfigurableApplicationContext context = SpringApplication.run(UserApplication.class, args);
        DemoService demoservice = context.getBean("demoService", DemoService.class);
        System.out.println(demoservice);
    }

}
