1.新建一個springboot專案

1.1 寫一個介面，定義一個say方法

public class HelloService {
    private HelloProperties helloProperties;

    public HelloService(HelloProperties helloProperties) {
        this.helloProperties = helloProperties;
    }

    public HelloProperties getHelloProperties() {
        return helloProperties;
 
    }

    public void setHelloProperties(HelloProperties helloProperties) {
        this.helloProperties = helloProperties;
    }

    public String say(){
        return helloProperties.getName();
    }
}
1.2 定義HelloProperties ，

@ConfigurationProperties(prefix = "com.zy")
public class HelloProperties {
    private String name;
 

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}
1.3 主配置類 啟動proeperties

@Configuration
@ConditionalOnWebApplication
@EnableConfigurationProperties(HelloProperties.class)
public class HelloConfiguration {
    @Autowired
    private HelloProperties helloProperties;
 
    

    @Bean
    public HelloService helloService(){
        return new HelloService(helloProperties);
    }
}
1.4 在resources下新建METAfactories檔案，在裡面寫上

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.zy.HelloConfiguration

1.5 打包該專案 jar包

2.新建另一個springboot專案

2.1 匯入上面專案的maven

<dependency>
   <groupId>org.example</groupId>
   <artifactId>zy-spring-boot-starter</artifactId>
   <version>1.0-SNAPSHOT</version>
</dependency>

2.2 application.properties中新增

com.zy.name=zhouyang

2.3新建一個HelloController

@RestController
public class HelloController {
    @Resource
    private HelloService helloService;
    @RequestMapping("hello")
    public String hello(){
        return helloService.say();
    }
}
2.4 測試
