java 属性复制 不用set,get方法

代码属性复制除了用BeanUtils.copyProperties方法外,使用这个方法也可以实现。在hibernate,持久化中这个方法很受用的。
import java.lang.reflect.Field;import java.lang.reflect.Method;public class CopyObject {public static Object copyProperties(Object rtuObject, Object object){Class classType = object.getClass();Class rtuClassType = rtuObject.getClass();Field fields[] =classType.getDeclaredFields();for(int i=0;i<fields.length;i++){Field field = fields[i];String fieldName = field.getName();String firstLetter = fieldName.substring(0,1).toUpperCase();String getMethodName = "get"+firstLetter+fieldName.substring(1);String setMethodName = "set"+firstLetter+fieldName.substring(1);try {Method getMethod = classType.getMethod(getMethodName,new Class[]{});Method setMethod = rtuClassType.getMethod(setMethodName,new Class[]{field.getType()});Object value = getMethod.invoke(object,new Object[]{});if (null!=value){setMethod.invoke(rtuObject,new Object[]{value});}} catch (Exception e) {e.printStackTrace();}}}return rtuObject;}
