問題是我想在 quarkus 中使用“將配置映射到物件”我有一個 gradle.properties 所以我想在 .properties 檔案中宣告這個物件陣列，
myApplicationConfig.enabled = true我想獲取并使用這個值，我們可以通過使用@ConfigMapping(prefix = myApplicationConfig) 作為介面頂部的注釋，用于映射我的介面代碼：
@ConfigMapping(prefix = "myApplicationConfig")
@StaticInitSafe
public interface ApplicationConfig {
boolean enabled();
List<Details> details();
interface details{
String name();
int age();}
在注入這個之后，enabled()我想把它提取到其他類，我想做一些操作，比如列印值，所以我在那里注入了這個介面并試圖獲取值，但它說

我無法注入資料任何人都可以解釋為什么我不能？還是我錯過了什么？還是我需要在 build.gradle 或其他地方添加這些配置？而且我想宣告一個物件陣列為
Config.details[0].name = "Sam"
Config.details[0].age = 12
Config.details[1].name = "Tim"
Config.details[1].age = "34"
但是當我在注入后嘗試使用它們時會拋出空串列，請解釋一下:)
uj5u.com熱心網友回復：
檔案
1. 配置源 默認情況下，Quarkus 從多個源讀取配置屬性（按降序排列）：
(400) 系統屬性
(300) 環境變數
(295) 當前作業目錄中的 .env 檔案
(260) $PWD/config/application.properties 中的 Quarkus 應用程式組態檔
（250）類路徑中的Quarkus應用程式組態檔application.properties
(100) 類路徑中的MicroProfile Config組態檔META-INF/microprofile-config.properties
最終配置是所有這些來源定義的屬性的聚合。配置屬性查找從可用的最高序號配置源開始，一直向下到其他源，直到找到匹配項。這意味著任何配置屬性都可以通過在更高的序數配置源中設定不同的值來覆寫一個值。例如，使用環境屬性配置的屬性會覆寫使用 application.properties 檔案提供的值。
gradle 用于構建專案，默認情況下不向quarkus.
因此，選擇上述目的地之一，然后添加您的配置屬性，然后從中選擇quarkus
例如，您可以添加
myApplicationConfig.enabled = true
myApplicationConfig.details[0].name = "Sam"
myApplicationConfig.details[0].age = 12
myApplicationConfig.details[1].name = "Tim"
myApplicationConfig.details[1].age = "34"
在檔案中src/main/resources/application.properties。
