Question

多条件查询的hql语句在hibernate生成的dao类中应该怎么写？包括整个方法体？

public Transfer findTransfer(Transfer transfer) {
String queryString=("select * from Transfer s where s.transferId in(:myids) ");
if(x.equal("")){queryString+="and x='x'";}

Transfer tran=(Transfer) super.getHibernateTemplate().find(queryString);
return tran;
}
错误的代码帮忙应该怎么写

Answer 1

if(transfer.getX()!=null && !"".equal(transfer.getX()))
{
queryString+=" and x='"+transfer.getX()+"'";
}
System.out.println("queryString="+queryString);

Answer 2

判断条件有问题吧 应该是if(transfer.getx()!=null&&!"".equal(transfer.getx())){
......
}
