public class SysParam {
    //行政区划代码前台显示默认值
    private String zoneCode;
    //二代证读卡器读取照片存储位置
    private String sfzpicpath;
    //保存身份证照片相对路径
    private String photoRealPath;
    public String getZoneCode() {
        return zoneCode;
    }
    public void setZoneCode(String zoneCode) {
        this.zoneCode = zoneCode;
    }
    public String getSfzpicpath() {
        return sfzpicpath;
    }
    public void setSfzpicpath(String sfzpicpath) {
        this.sfzpicpath = sfzpicpath;
    }
    public String getPhotoRealPath() {
        return photoRealPath;
    }
    public void setPhotoRealPath(String photoRealPath) {
        this.photoRealPath = photoRealPath;
    }
}

使用

private static ApplicationContext cpxac = new ClassPathXmlApplicationContext("tysfrz/spring/tysfrz_params.xml");
private static SysParam sysparam = (SysParam) cpxac.getBean("SysParam");

String photorealpath = sysparam.getPhotoRealPath();
