Spring boot 无法解析占位符 application.yml

Question

我是春天的新人，我遇到了麻烦。当我使用 IntelliJ Idea 运行我的应用程序时，一切正常，但是当我将它编译为 .jar 应用程序时，这给了我这个错误 java.lang.IllegalArgumentException: Could not resolve placeholder 'jwt.secret' in value "${jwt.secret}"

这是我的 application.yml 位于 src/main/resources

 #Config Application
jwt:
  header: Authorization
  secret: mySecret
  expiration: 604800
  route:
    authentication:
      path: auth
      refresh: refresh
      token: check

当我把我的改成这个时，它工作得很好。

 //    @Value("${jwt.secret}")
    @Value("mySecret")
    private String secret;

我做错了什么？

注意：我正在使用 MAVEN

这是我的 pom.xml

Answer 1

糟糕的是我正在使用 Intellij Idea 进行构建。使用此命令构建：

 ./mvnw clean package

@Autowired
private Environment env;

env.getProperty("jwt.secret")

你可以试试！
