我有一个Spring Boot（Jhipster生成）项目。当我使用./mvnw运行我的项目时效果很好但是当我尝试mvn package或mvn clean install时它会崩溃：
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'application.hotspot.path.audio' in value "${application.hotspot.path.audio}"
和
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'applicationProperties': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'application.hotspot.path.audio' in value "${application.hotspot.path.audio}"
我的YAML configuartion（没关系，检查一下）：
application:
gateway: 192.168.0.1
host: 192.168.0.2
hotspot:
path:
audio: my-audio-config
我的ApplicationProperties类：
@Component
@ConfigurationProperties("application")
public class ApplicationProperties {
@Value("${application.hotspot.path.audio}")
private String audioPath;
...getters/setters...
}

答案 0 :(得分：2)
您不必重复前缀：application。
所以这应该没问题：
@Value("${hotspot.path.audio}")
private String audioPath;
答案 1 :(得分：0)
当你j时，我不确定它对你有什么作用。它无法工作，因为您已指定
./mvnw这意味着春天会搜寻像是的财产
@ConfigurationProperties("application")
它找不到。
两种选择。
1.只需指定application.application.hotspot.path.audio
2
@ConfigurationProperties
