1：创建maven项目

2：pom文件

    </dependencies>


</project>

3：config

package com.ikeeper.config;

import com.ikeeper.properties.MyAutoProperties;
import com.ikeeper.service.DemoService;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableConfigurationProperties({MyAutoProperties.class})
public class MyAutoBeanConfig {
    @Bean
   public DemoService demoService(MyAutoProperties myAutoProperties){
        DemoService demoService = new DemoService();
        demoService.setMyAutoProperties(myAutoProperties);
        return demoService;
    }
}

4.配置类

package com.ikeeper.properties;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix ="my.auto")
public class MyAutoProperties {
    private int point;

    public int getPoint() {
        return point;
    }

    public void setPoint(int point) {
        this.point = point;
    }
}

5：service

package com.ikeeper.service;

import com.ikeeper.properties.MyAutoProperties;

public class DemoService {

    private MyAutoProperties myAutoProperties;

    public String hi(String name){
        return "hello:"+name + "."+myAutoProperties.getPoint();
    }

    public void setMyAutoProperties(MyAutoProperties myAutoProperties) {
        this.myAutoProperties = myAutoProperties;
    }
}

6：META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration = \
com.ikeeper.config.MyAutoBeanConfig

7:starter目录结构

8：其他应用业务代码pom依赖

    <dependency>
      <groupId>com.ikeeper</groupId>
      <artifactId>my-auto-bean-starter</artifactId>
      <version>1.0.1-SNAPSHOT</version>
    </dependency>

9：业务配置

my.auto.point: 10

10：测试

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {AppMain.class})
public class SpringTest {
    @Autowired
    DemoService demoService;
    @Test
    public void hi(){
        System.out.println(demoService.hi("henha"));
    }
}
