1：创建maven项目

2：pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.ikeeper</groupId><artifactId>my-auto-bean-starter</artifactId><version>1.0.1-SNAPSHOT</version><packaging>jar</packaging><name>my-auto-bean-starter</name><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.7.RELEASE</version></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId><scope>compile</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId></dependency></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 {@Beanpublic 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 {@AutowiredDemoService demoService;@Testpublic void hi(){System.out.println(demoService.hi("henha"));}
}
