java - 从 application.yml 读取配置到 POJO 列表的 Map

问题描述

我有这个application.yml文件

messages:
  first-journey-messages:
    - key: fullName-required
      value: This field is required.
    - key: fullName-validation
      value: Please enter a valid full name.
    - key: technical-error
      value: Unfortunately we are having technical issues, please try again later.
  second-journey-messages:
    - key: technical-error
      value: "<p class='heading-bold'>Sorry, something went wrong </p><p>We encountered a technical error. Please try again. If you continue to experience difficulties, please call us on 0123456 and an agent will be happy to assist you.</p>"
    - key: download-technical-error
      value: "<p class='heading-bold'>Sorry, something went wrong </p><p>Unable to download document at this moment. Please try again later.</p>"
  third-journey-messages:
    - key: home-url
      value: /app/home
    - key: services-url
      value: /app/services

我想使用注释在下面的Map对象中阅读上面的配置。@Value

@Value("${messages}")
private Map<String, List<MessageEntry>> messagesMap = new HashMap<>();

POJO：MessageEntry

@Data
@AllArgsConstructor
public class MessageEntry implements Serializable {
    private String key;
    private String value;
}

当我尝试读取配置时，我得到null.

messagesMap.get("second-journey-messages")

有人可以帮我识别，我做错了什么吗？或者，我怎样才能将上述配置读取为类型的对象Map<String, List<MessageEntry>>？

注意：我正在使用带有lombok的弹簧靴

解决方案

我认为这个答案可以帮助你链接。尝试更改 yml 文件中的键值符号。
