Springboot加载自定义yml文件配置的方法
-
ConfigurationProperties注解的locations属性在1.5.X以后没有了,不能指定locations来加载yml文件
-
PropertySource注解不支持yml文件加载,详细见官方文档:
- Spring Framework有两个类加载YAML文件,YamlPropertiesFactoryBean和YamlMapFactoryBean
- 可以通过PropertySourcePlaceholderConfigurer来加载yml文件,暴露yml文件到spring environment

@Configuration
public class SpringBootConfigura {
// 加载YML格式自定义配置文件
@Bean
public static PropertySourcesPlaceholderConfigurer properties() {
PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
yaml.setResources(new ClassPathResource("config.yml"));//File引入
configurer.setProperties(yaml.getObject());
return configurer;
}
}
配置文件:
my:
servers:
- dev.example.com
- another.example.com
- ${random.value}
- 测试
@Controller
public class SpringBootTest {
@Autowired
Config config;
@GetMapping("/testConfig")
@ResponseBody
public String testConfig(){
return config.getServers().toString();
}
}
