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;
