通过BeanMap 拷贝对象

一个小例子：
/**
* 单元测试
* Object target,Object source
* @param arg
*/
@SuppressWarnings("unchecked")
public static void main(String arg[]){
PrpLregist source = new PrpLregist();
source.setRegistNo("123456789test");

PrpLregist target = new PrpLregist();

Map<String,Object> sourceMap = BeanMap.create(source);
Map<String,Object> targetMap = BeanMap.create(target);

for(String keyName : sourceMap.keySet()){
Object sourceValue = sourceMap.get(keyName);

if(sourceValue == null){
//是否拷贝空,暂时不拷贝
}
else if(isBaseObject(sourceValue)){//是否常用的基本类型
targetMap.put(keyName,sourceValue);

}
else if(sourceValue  instanceof Collection){
Collection c = (Collection)sourceValue;
if(!c.isEmpty()){
targetMap.put(keyName,sourceValue);
}
}
else if(sourceValue.getClass().isArray()){
Object[] a = (Object[])sourceValue;
if(a.length>0){
targetMap.put(keyName,sourceValue);
}
}
}
System.out.println(target.getRegistNo());
}

/**
* 判断是否基本对象（即无需处理的对象）
* @param obj
* @return
*/
public static boolean isBaseObject(Object obj){
if(obj instanceof String
||obj instanceof Number
||obj instanceof Character
||obj instanceof Boolean
||obj instanceof Byte
||obj instanceof Date
||obj.getClass().isPrimitive()
){
return true;
}
return false;
}
