我在Spring Boot的资源类路径位置中有多个yml文件,例如Spring Boot的以下结构。最初,我只为application-abc.yml编写文件,并且此文件的所有值均已加载到其相应的类中,但是当我在另一个文件中添加了application-xyz.yml时,它也加载到了其相应的配置类中,但是目前,仅在两个配置类中都加载application-xyz.yml的值。因此,需要帮助来在单个构建中配置它们相应的配置文件中两个文件的值:
-src
-main
-java
-packages
-config
-ApplicationAbcConfig.java
-ApplicationConfig.java
-ApplicationFactory.java
-ApplicationXyzConfig.java
-Authentication.java
-Operations.java
-Payload.java
-RequestPayload.java
-ResponsePayload.java
-services
-YmlConfigurationSelection.java
-resources
-application.yml
-application-abc.yml
-application-xyz.yml
-MultipleYmlDemoProject.java

似乎您有一个试图迁移到Spring Boot的旧的Spring应用程序。
Spring boot本机可与yaml文件一起使用,因此,如果以spring boot方式进行集成,则可以删除许多必须维护的样板代码。另外,配置的命名也是有问题的:名称application-<something>.yml
保留用于Spring Boot配置文件,也许如果您重命名为myprops-abc/xyz.yaml
,它将以不同的方式运行,我不能肯定地说。 >
总的来说,我建议您采用以下方式,这比IMO好得多:
@ConfigurationProperties(prexix="security")
public class SecurityConfigProperties {
private SecurityRealm abc;
private SecurityRealm xyz;
// getters, setters
}
public class SecurityRealm {
private Authentication autentication;
private Operations operations;
// getters setters
}
public class Authentication {...}
private class Operations {...}
application.yaml
,并提供一个'security'前缀:
security:
abc: // note, this 'abc' matches the field name of the configuration
authentication:
...
operations:
....
xyz:
authentication:
...
operations:
....
@Configuration
@EnableConfigurationProperties(SecurityConfigProperties.class)
public class SecurityConfiguration {
@Bean
public SecurityBeanForABC(SecurityConfigProperties config) {
return new SecurityBeanForABC(config.getAbc().getAuthentication(), config.getAbc().getOperations());
}
... the same for XYZ
}
注意,使用这种方法,您仅在java对象中维护配置映射,并且没有用于加载/解析属性的代码)-一切都由spring boot自动完成。如果配置特殊的注释处理器并具有下降的IDE,您甚至可以为这些yaml属性获得自动完成功能,但此问题超出了范围。关键是,以Spring Boot直接支持的方式进行操作有很多优点:)
