配置文件类

@ConfigurationProperties(prefix = "test.hello")public class HelloProperties {
       private String suffix;    public String getSuffix() {
           return suffix;    }    public void setSuffix(String suffix) {
           this.suffix = suffix;    }}

服务类

public class HelloService {
       HelloProperties helloProperties;    public String sayHello(String name) {
           return "Hello " + name + "，" + helloProperties.getSuffix();    }    public HelloProperties getHelloProperties() {
           return helloProperties;    }    public void setHelloProperties(HelloProperties helloProperties) {
           this.helloProperties = helloProperties;    }}

注册类

/** * web应用才生效 */@ConditionalOnWebApplication/** * 让属性文件生效 */@EnableConfigurationProperties(HelloProperties.class)/*** * 声明是一个配置类 */@Slf4j@Configurationpublic class HelloServiceAutoConfiguration {
       @Autowired    private HelloProperties helloProperties;    @Bean    public HelloService helloService() {
           log.info("开始注册HelloService Bean");        HelloService helloService = new HelloService();        helloService.setHelloProperties(helloProperties);        return helloService;    }}

test-spring-boot-starter

配置类

测试在SpringBoot项目中，pom.xml引入自动配置项目

               
    
     com.test
                
    
     test-spring-boot-starter
                
    
     1.0-SNAPSHOT
            
   

配置

test.hello.suffix=早上好

注入HelloService,即可使用。

@Autowired    private HelloService helloService;
