java - 不工作 spring.config.additional-location

Question

maven :

<profiles>
    <profile>
        <id>local</id>
        <activation>
           <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <active.spring.profile>local</active.spring.profile>
        </properties>
    </profile>
</profiles>

应用程序属性:

spring.profiles.active=@active.spring.profile@
spring.config.additional-location=classpath:/profile/application-${spring.profiles.active}.properties

在此之后我无法从包含 test.prop=123

的 src/main/resources/application-local.properties 获取值

@Service
public class TestProps {

    @Value("${test.prop}")
    String testProp;

    @PostConstruct
    void run() {
        System.out.println(testProp);
    }
}

错在哪里？还是错误？

属性:spring.config.additional-location 必须像这样作为 JVM 的参数提供:java -Dspring.config.additional-location=classpath:/profile/application -local.properties -jar whatever.jar.

将它放在 application.properties 中没有意义。来自documentation :

Alternatively, when custom config locations are configured by usingspring.config.additional-location, they are used in addition to thedefault locations. Additional locations are searched before thedefault locations.

因为附加位置是在默认位置之前搜索的，所以它们必须更早提供，因此您不能在application.properties
