坑：@ConfigurationProperties获取不到配置文件属性值

application.yml

配置类

&＃64;Component
&＃64;ConfigurationProperties(prefix &＃61; "system")
public class SystemConfig {/*** 项目名称*/private static String name;/*** 版本*/private String version;/*** 版权年份*/private String copyrightYear;/*** 实例演示开关*/private boolean demoEnabled;/*** windows环境下,文件上传路径(本地上传)*/private static String winUploadPath;/*** 其他系统环境(linux、Mac...)环境下,文件上传路径(本地上传)*/private static String otherUploadPath;/*** 获取地址开关*/private static boolean addressEnabled;public static String getName() {return name;}public void setName(String name) {SystemConfig.name &＃61; name;}public String getVersion() {return version;}public void setVersion(String version) {this.version &＃61; version;}public String getCopyrightYear() {return copyrightYear;}public void setCopyrightYear(String copyrightYear) {this.copyrightYear &＃61; copyrightYear;}public boolean isDemoEnabled() {return demoEnabled;}public void setDemoEnabled(boolean demoEnabled) {this.demoEnabled &＃61; demoEnabled;}public static String getWinUploadPath() {return winUploadPath;}public static void setWinUploadPath(String winUploadPath) {SystemConfig.winUploadPath &＃61; winUploadPath;}public static String getOtherUploadPath() {return otherUploadPath;}public static void setOtherUploadPath(String otherUploadPath) {SystemConfig.otherUploadPath &＃61; otherUploadPath;}public static boolean isAddressEnabled() {return addressEnabled;}public void setAddressEnabled(boolean addressEnabled) {SystemConfig.addressEnabled &＃61; addressEnabled;}/*** 判断当前操作系统&＃xff0c;返回相应的本地上传路径** &＃64;return String* &＃64;author Liangyixiang* &＃64;date 2021/11/15**/public static String getUploadPath() {OsInfo osInfo &＃61; SystemUtil.getOsInfo();// 判断系统环境获取上传路径if(ObjectUtils.isNotEmpty(osInfo) && osInfo.isWindows()){return getWinUploadPath();}else{return getOtherUploadPath();}}/*** 获取业务系统名称*/public static String getSystemName() {return getName();}}


name、addressEnabled 以及 winUploadPath、otherUploadPath 都是静态的成员变量&＃xff0c;但是他们name、addressEnabled能获取到配置文件的值&＃xff0c;winUploadPath、otherUploadPath不可以。
原因就是&＃xff1a; winUploadPath、otherUploadPath对应的ser方法也定义为了静态方法。
