Java Maven YAML解决Spring引导应用程序中的错误

我有一个SpringBoot（Jhipster生成的）项目。当我使用

/mvnw

运行我的项目时，它运行得很好，但当我尝试

mvn包

或

mvn干净安装时，它崩溃了：


Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'application.hotspot.path.audio' in value "${application.hotspot.path.audio}"

So this should be fine :


@Value("${hotspot.path.audio}")
private String audioPath;

：：JHipster您不必重复前缀：
application


所以这应该是好的：

@ConfigurationProperties("application")

当您执行
/mvnw
时，我不确定它对您有何作用。它无法工作，因为您已指定

@Value("${hotspot.path.audio}")
 private String audioPath;

这意味着spring将搜索类似

application.application.hotspot.path.audio


它找不到

两种选择。

1.只需指定
@ConfigurationProperties


二,

我也试过了，但没用。你们看，这个应用程序很好用。问题是当我通过maven Tasks运行它时，您是否可以用整个输出（命令执行+异常）编辑您的问题？是的，添加了。看看：）很好！我认为YAML文件不在类路径中，mvnw可能会在运行spring引导应用程序时添加它。如果你可以编辑问题中的mvnw内容，这可能会有所帮助。不，不起作用。我已经应用了你的建议，但不知何故，该应用程序甚至与我的配置一起工作：你不应该在同一个类上混合使用
@Value
和
@ConfigurationProperties
<配置属性类上的code>@Component
也有点非典型。您可能希望在使用属性的类上使用
@EnableConfigurationProperties
。

So this should be fine :

private String audioPath;

@ConfigurationProperties("application")

@Value("${hotspot.path.audio}")
 private String audioPath;
