SysParam.java类文件

package com.wisoft.tysfrz.utils;
/**

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();

需要引用包

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
