+ private String title; + // get,set略 +} +``` + + + +通过注解`@ConfigurationProperties(prefix="mrbird.blog")`指明了属性的通用前缀，通用前缀加属性名和配置文件的属性名一一对应。 + +除此之外还需在Spring Boot入口类加上注解`@EnableConfigurationProperties({ConfigBean.class})`来启用该配置： + +``` +@SpringBootApplication +@EnableConfigurationProperties({ConfigBean.class}) +public class Application { + + public static void main(String[] args) { + SpringApplication.run(Application.class, args); + } +} +``` + + + +之后便可在IndexController中注入该Bean，并使用了： + +``` +@RestController +public class IndexController { + @Autowired + private ConfigBean configBean; + + @RequestMapping("/") + String index() { + return configBean.getName()+"——"+configBean.getTitle();
