Java 如何使用Spring框架使用YAML文件？

我的应用程序是基于spring的，我想从一个集中式服务器加载yml文件，但服务器无法这样做

我的yml文件如下所示：

spring:
  application:
    name: signed-in-web
  cloud:
    config:
      uri: ${server.url}
health:
  config:
    enabled: false

@Profile("!test")
@ComponentScan(basePackages = { "com.company.frontend.*" })
@Configuration
@PropertySource("classpath:properties/qa_env.properties")
public class propertiesConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
        YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
        yaml.setResources(new ClassPathResource("bootstrap.yml"));
            propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
        return propertySourcesPlaceholderConfigurer;
    }
}

@Value("${LOCATION_SEARCH}")
public static String LOCATION_SEARCH;

注意：server.url在vm选项中定义。 我已经从rest客户端检查了属性是否有效并且在服务器上可用

然后我尝试将其复制到属性文件中，如下所示： 应用程序属性

LOCATION_SEARCH=${properties.app.api-key.location-search}

我有如下java配置类：

spring:
  application:
    name: signed-in-web
  cloud:
    config:
      uri: ${server.url}
health:
  config:
    enabled: false

@Profile("!test")
@ComponentScan(basePackages = { "com.company.frontend.*" })
@Configuration
@PropertySource("classpath:properties/qa_env.properties")
public class propertiesConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
        YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
        yaml.setResources(new ClassPathResource("bootstrap.yml"));
            propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
        return propertySourcesPlaceholderConfigurer;
    }
}

@Value("${LOCATION_SEARCH}")
public static String LOCATION_SEARCH;

我想这会像这样加载配置：

spring:
  application:
    name: signed-in-web
  cloud:
    config:
      uri: ${server.url}
health:
  config:
    enabled: false

@Profile("!test")
@ComponentScan(basePackages = { "com.company.frontend.*" })
@Configuration
@PropertySource("classpath:properties/qa_env.properties")
public class propertiesConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer properties() {
        PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
        YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
        yaml.setResources(new ClassPathResource("bootstrap.yml"));
            propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
        return propertySourcesPlaceholderConfigurer;
    }
}

@Value("${LOCATION_SEARCH}")
public static String LOCATION_SEARCH;

但是我正在变空。不知何故，我无法找到问题所在。将

如果使用Spring Boot，只需调用它

应用程序qa.yaml

并启用

qa

配置文件。另请参见中的

spring.config

和

spring.profiles

否则，您只需要在

@PropertySource

或

@PropertySources

中声明yaml文件

只有当您不希望全局环境中的属性时，才开始需要使用

属性配置工厂

和

YamlPropertiesFactoryBean

手动绑定它们
