处理hibernte多表查询返回对象集合的解决办法

public class BeanProperty {
	
	private static final String FILTER_REG = "serialVersionUID";

	public static List<?> arrayCastBean(String dir,List<Object[]> list) {
		List<Object> result = new ArrayList<Object>();
		boolean flag = false;
		try {
			Class<?> clazz = Class.forName(dir);
			Object obj = null;
			Field[] fields = clazz.getDeclaredFields();
			if(fields[0].getName().equals(BeanProperty.FILTER_REG)){
				flag = true;
			}
			for(Object[] values : list){
				obj = clazz.newInstance();
				for(int i=0;i<fields.length;i++){
					if(!fields[i].getName().equals(BeanProperty.FILTER_REG)){
						PropertyDescriptor pd = new PropertyDescriptor(fields[i].getName(), clazz);
						Method m = pd.getWriteMethod();
						m.invoke(obj, values[flag?(i-1):i]==null?"":values[flag?(i-1):i].toString());
					}
				}
				result.add(obj);
			}
		} catch (ClassNotFoundException e1) {
			e1.printStackTrace();
		} catch (IllegalAccessException e2) {
			e2.printStackTrace();
		} catch (InstantiationException e3) {
			e3.printStackTrace();
		} catch (IllegalArgumentException e6) {
			e6.printStackTrace();
		} catch (IntrospectionException e4) {
			e4.printStackTrace();
		} catch (InvocationTargetException e5) {
			e5.printStackTrace();
		}
		return result;
	}

 

 

最后将返回的list强转成你传的地址的javabean就可以了
