java Spring引导无法解析占位符应用程序。yml

Question

春天我是新来的，有点麻烦。 当我用IntelliJ Idea运行应用程序时，一切都很完美，但当我将其编译为。jar应用程序给我这个错误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

当我改成这个的时候，效果非常好

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

我做错了什么

注意：我使用的是MAVEN

这是我的pom。xml

Answer 1

@Autowired
private Environment env;

env.getProperty("jwt.secret")

你可以试试

Answer 2

你犯了个小错误。 看看你的申请表。yml：

 jwt:
  header: Authorization
  secret: mySecret

财产名称是“秘密”而不是“我的秘密”。您不小心绑定到了值而不是属性名。只需替换：

@Value("mySecret")

据此：

@Value("secret")

然而，您的错误消息表明您使用了注释掉的“jws.secret”。请记住，如果您使用前缀（例如“jws”），那么您只能通过“secret”引用该属性
