Map<String, Object> fieldMap =new HashMap<String, Object>();

BeanInfo beanInfo = Introspector.getBeanInfo(【javabean类名】.class, Object.class); 
//获取所有的属性描述器 
PropertyDescriptor[] pds = beanInfo.getPropertyDescriptors(); 
for(PropertyDescriptor pd:pds){ 
String key = pd.getName(); 
Method getter = pd.getReadMethod(); 
Object value = getter.invoke(【实例化的javaBean】);
