Question

因此，我尝试根据https://docs.spring.io/spring-boot/docs/current/reference/html/configuration-metadata.html#configuration-metadata-annotation-processor上提供的文档，通过@ConfigurationProperties项生成自己的配置元数据。请注意，我正在使用Spring Boot 2.0和Kotlin。

它工作正常，除了一件事：defaultValue字段没有用我的默认值填充，而是只包含0或false之类的标准值。

我的@ConfigurationProperties文件如下所示：

@Component
@ConfigurationProperties("flowr.epg")
class EpgProperties {
    /** Whether or not schedules should be computed/refreshed on (re)start */
    var refreshOnRestart = true
    /** Number of threads used to store new images */
    var nImagesUploadThreads = 10
}

结果如下：

{
  "hints": [],
  "groups": [
    {
      "sourceType": "com.taktik.flowr.epg.properties.EpgProperties",
      "name": "flowr.epg",
      "type": "com.taktik.flowr.epg.properties.EpgProperties"
    }
  ],
  "properties": [
{
  "sourceType": "com.taktik.flowr.epg.properties.EpgProperties",
  "defaultValue": false,
  "name": "flowr.epg.refresh-on-restart",
  "description": "Whether or not schedules should be computed\/refreshed on (re)start",
  "type": "java.lang.Boolean"
},
{
  "sourceType": "com.taktik.flowr.epg.properties.EpgProperties",
  "defaultValue": 0,
  "name": "flowr.epg.n-images-upload-threads",
  "description": "Number of threads used to store new images in Ozone",
  "type": "java.lang.Integer"
}
}

该文档对于该defaultValue字段有点差劲。难道我做错了什么？是否可以自动填充该defaultValue字段？如果是，我在做什么错了？
