springboot 3应用程序yml属性@value

Question

在我的 application.yml 中我有以下内容

cors-allowed-origins:
  url-origins:
     - http://host.docker.internal:81/
     - http://localhost:8081/*
     - http://digitale.com/
     - http://share.com/

第一个记录

@ConfigurationProperties( "cors-allowed-origins" )
public record CrosAllowedOrigins(List<String> urlOrigins) {

}

Could you please help me out or even tell me what s wrong thanks

在我注入值的类中

public class SecurityConfig {
    @Value("${cors-allowed-origins.url-origins}")
    private List<String> allowedOrigins;

我已经启用了主类中的属性

 @EnableConfigurationProperties({ CrosAllowedOrigins.class})

它构建完美，但是当我运行该应用程序时，我收到此错误：

我找到了解决该问题的方法，因此我没有将 Spring 的 @Autowired 注释与 @Value 一起使用，而是通过构造函数注入值，并且效果很好。

@RequiredArgsConstructor public class SecurityConfig  { //  @Value("${cors-allowed-origins.url-origins}") private final CrosAllowedOrigins allowedOrigins;
