net.sf.cglib.beans.BeanMap 重写toString()的用法

net.sf.cglib.beans.BeanMap 重写toString()的用法

在cglib 中 BeanMap的用法

1.导入cglib-nodep-2.1.3.jar
 
2.在javaBean 对象中重写toString()方法  比如是UserManageVo.Java
 public String toString(){
  return BeanTools.getBeanDesc(UserManageVo.this);
 }
java 代码

 1 package  BeanUtils;
 2
 3 import  net.sf.cglib.beans.BeanMap;
 4
 5 public   class  BeanTools  {
 6    private static String LINE = System.getProperty("line.separator", "\r\n");

12     * @return String

14    public static String getBeanDesc(Object obj) {
15        StringBuffer bf = new StringBuffer();
16        bf.append(LINE + "{" + LINE + "Class = " + obj.getClass().getName()
17                + LINE);
18        BeanMap beanMap = BeanMap.create(obj);
