4、内部代码
（1）spring-boot-starter-autoconfigurer module
package com.springboot.starter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**

@Configuration
@EnableConfigurationProperties(HelloProperties.class)
public class HelloAuto {
@Autowired
HelloProperties helloProperties;
@Bean
public HelloService helloService() {
HelloService helloService = new HelloService();
helloService.setHelloProperties(helloProperties);
return helloService;
}
}
package com.springboot.starter;
import org.springframework.boot.context.properties.ConfigurationProperties;
/**
@author:素小暖
@date:2020/2/9
@desc:
*/
@ConfigurationProperties(prefix = "springboot.hello")
public class HelloProperties {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
package com.springboot.starter;
/**
@author:素小暖
@date:2020/2/9
@desc:
*/
public class HelloService {
HelloProperties helloProperties;
public String hello() {
return "hello" + helloProperties.getName();
}
public HelloProperties getHelloProperties() {
return helloProperties;
}
public void setHelloProperties(HelloProperties helloProperties) {
this.helloProperties = helloProperties;
}
}
spring.properties 文件
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.springboot.starter.HelloAuto
POM 文件
<?xml version="1.0" encoding="UTF-8"?>

（2）?springbootstarter
启动器比较简单，只有 pom 文件，引入自动配置即可。
<?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>wms</groupId>
<artifactId>springboot-starter</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>com.springboot</groupId>
<artifactId>spring-boot-starter-autoconfigurer</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
5、?测试，新建 springboot 项目，pom 文件中引入启动器
<dependency>
<groupId>springboot</groupId>
