Micronaut @ConfigurationProperties 未正确加载到 pojo 列表中

Question

我的 application.yml 文件中有以下属性：

payment-routing-config:
  drivers:
    - id: 'ANETC'
      weight: 80
      backups: ['EPAYC', 'NMIC', 'ANETD']
    - id: 'EPAYC'
      weight: 80
      backups: ['ANETC', 'NMIC', 'ANETD']
    - id: 'NMI'
      weight: 80
      backups: ['EPAYC', 'ANETC', 'ANETD']

以及以下 Java：

@ConfigurationProperties("paymentRoutingConfig")
public record PaymentRoutingConfig(
    List<PaymentDriver> drivers
) { }

record PaymentDriver(
    String id,
    int weight,
    List<String> backups
) { }

当我使用@Inject加载配置时，drivers属性是一个空列表。如果我将列表驱动程序更改为列表驱动程序，我将填充以下对象：

PaymentRoutingConfig[drivers=[{id=ANETC, weight=80, backups=[EPAYC, NMIC, ANETD]}, {id=EPAYC, weight=80, backups=[ANETC, NMIC, ANETD]}, {id=NMI, weight=80, backups=[EPAYC, ANETC, ANETD]}]]

这就是我将其注入控制器的方式：

@Inject
PaymentRoutingConfig paymentRoutingConfig;

复杂对象是否无法与@ConfigurationProperties一起使用？

我什至尝试将 List 简化为单个对象：

@ConfigurationProperties("paymentRoutingConfig")
public record PaymentRoutingConfig(
    PaymentDriver driver
) { }

record PaymentDriver(
    String id,
    int weight
) { }

yaml：

payment-routing-config:
  driver:
    id: 'test'
    weight: 10

我收到此错误：

Message: Failed to inject value for parameter [driver] of class: com.***.paymentservice.infrastructure.PaymentRoutingConfig

Message: Error resolving property value [payment-routing-config.driver]. Property doesn't exist
Path Taken: new PaymentController() --> PaymentController.paymentRoutingConfig --> new PaymentRoutingConfig([PaymentDriver driver])

io.micronaut.context.exceptions.DependencyInjectionException: Failed to inject value for parameter [driver] of class: com.***.paymentservice.infrastructure.PaymentRoutingConfig

Answer 1

在我的 yaml 文件中使用以下内容，我能够正确填充配置对象：

payment-routing-config:
  drivers: [
    {id: 'test', weight: 10, backups: ['EPAYC', 'ANETC', 'ANETD']},
    {id: 'test2', weight: 20, backups: ['ANETC', 'EPAYC', 'ANETD']}
  ]
