Hibernate从数据库中获取列表 [英] Hibernate get List from database

问题描述

在下面的代码中，我试图获取包含数据库中所有产品的产品列表:

In the following code I am trying to get a List of Products which contains all the products in the database:

public List<Products> getAllProducts() throws Exception{
    try{
     List<Products> products ;
    org.hibernate.Transaction tx = session.beginTransaction();
    products = session.createSQLQuery("SELECT * FROM Products").list();
    if(products.size() > 0)
    {
        return products;
    }
    return null;  
    }
    catch(Exception e)
    {
        throw e;
    }
}

但是会抛出此异常:

[Ljava.lang.Object; cannot be cast to mediatek.Products 

推荐答案

List<Products> list = session.createCriteria(Products.class).list();

这将为您提供数据库中产品表的所有记录

This will give you all the records of products table from database
