castor Unmarshaller 读取XMl文件 运行没报错，但是读取值为null 问题解决

jar包：

castor-0.9.5.2.jar

xerces-J_1.4.0.jar

 

 

package com.download;

public class DownloadConfig {
 private  String dburl;
 private  String dbusername;
 private  String dbpsw;
 private  String downfilepath;
 public String getDburl() {
  return dburl;
 }
 public void setDburl(String dburl) {
  this.dburl = dburl;
 }
 public String getDbusername() {
  return dbusername;
 }
 public void setDbusername(String dbusername) {
  this.dbusername = dbusername;
 }
 public String getDbpsw() {
  return dbpsw;
 }
 public void setDbpsw(String dbpsw) {
  this.dbpsw = dbpsw;
 }
 public String getDownfilepath() {
  return downfilepath;
 }
 public void setDownfilepath(String downfilepath) {
  this.downfilepath = downfilepath;
 }

}

/*********************************/

 

 DownloadConfig downloadConfig = null;
     Reader reader = null;
   try {
   reader = new FileReader("C://tomcat-6-AxisWS//bin//downloadConfig.xml");
    System.out.print("C://tomcat-6-AxisWS//bin//downloadConfig.xml");
   if(reader.hashCode()>0) System.out.print("has code！");
   downloadConfig = (DownloadConfig) Unmarshaller.unmarshal(DownloadConfig.class, reader);
  } catch (Exception e) {
   e.printStackTrace();
   
  }
    System.out.print("读配置文件:"+downloadConfig.getDburl()+" "+downloadConfig.getDbusername()+" "+downloadConfig.getDbpsw());
  
  

 

 

以上为主要代码，运行通过。

castor Unmarshaller 读取XMl文件 运行没报错，但是读取值为null 问题，

由于一开始把DownloadConfig javabean 定义了静态 既 private static  String  dburl 导致
