如何对配置java进行封装

Question

我已经从 yml 读取了我的配置，并且我还为我的项目添加了配置 java 文件，但不知何故我无法封装它们，我有点困惑如何将它们作为私有字段；

下面是我的yml；

conf-listener:
  listenConfForInfoEvent:
    second: 19000
  listenConfForWarnEvent:
    second: 29000
  listenConfForErrorEvent:
    second: 39000

下面是我的班级；

@Configuration
@ConfigurationProperties(prefix = "conf-listener")
public class ConfEventListenerConfiguration {

    ListenConfEvent listenConfForInfoEvent = new ListenConfEvent ();
    ListenConfEvent listenConfForWarnEvent = new ListenConfEvent ();
    ListenConfEvent listenConfForErrorEvent = new ListenConfEvent ();

   // public getter and setters

    public static class ListenConfEvent {
        int hour = 0;
        int minute = 0;
        int second = 0;
        int milliSecond = 0;

      // public getters and setters

不知何故我无法封装它们，任何帮助

您不必通过new 创建对象，让 spring 为您完成。请在下面尝试并查看。如果这不起作用，那么您需要检查您的 .yaml 文件是否格式正确且没有间距问题。

@Configuration
@ConfigurationProperties(prefix = "conf-listener")
public class ConfEventListenerConfiguration {

    private ListenConfEvent listenConfForInfoEvent;
    private ListenConfEvent listenConfForWarnEvent;
    private ListenConfEvent listenConfForErrorEvent;

   // public getter and setters

    public static class ListenConfEvent {
        private int second;
       // public getter and setters
     }
}
