ConfigurationProperties注入静态变量的坑

private static String copyrightYear;

public static String getCopyrightYear() {
    return copyrightYear;
}
//set方法不能带上static
public void setCopyrightYear(String copyrightYear) {
    HaiAnConfig.copyrightYear = copyrightYear;
}
/*
//这样子注入不进
public static void setCopyrightYear(String copyrightYear) {
    HaiAnConfig.copyrightYear = copyrightYear;
}
*/
