1. 新建staticCls.properties

com.md.name="abc"
com.md.want="def"
#该随机值只是每次启动时生成一个固定值
com.md.id=${random.int}

2. 新建StaticCls.java

@Configuration
@ConfigurationProperties(prefix = "com.md")
@PropertySource("classpath:staticCls.properties")
public class StaticCls {
    private Long id;
    private String name;
    private String want;
    get()/set()
}

3. 在SpringBoot启动类上加注解

@SpringBootApplication
@ComponentScan(basePackages = "com.yweb")
/*配置类*/
@EnableConfigurationProperties({StaticCls.class})
public class Entry {
    public static void main(String[] args) throws Exception {
        SpringApplication.run(Entry.class, args);
    }
}
