弹簧启动 无法解析占位符应用程序。yml

2022-09-03 07:44:50

我是春天的新手,我有一个麻烦。当我使用IntelliJ Idea运行我的应用程序时,一切都很完美,但是当我将其编译为.jar应用程序时,这会给我这个错误java.lang.IllegalArgumentException: Could not resolve placeholder 'jwt.secret' in value "${jwt.secret}"

这是我位于application.ymlsrc/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,它工作完美。

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

我做错了什么?

注意:我正在使用MAVEN

这是我的绒球.xml

答案 1

我的坏我是用Intellij Idea构建的。使用此命令构建:

./mvnw clean package

答案 2
@Autowired
private Environment env;

env.getProperty("jwt.secret")

你可以试试!
