Hibernate Criteraia无法从数据库中检索数据

嗨，我是Hibernate的新手，因为我正在使用Criteria从数据库中检索数据，但是如果记录也匹配，则无法获取数据。以下是我使用的代码段。以下方法主要用于通过与（adminUser列的QuickUrlAdmin表）进行比较来检查列表（组）中的用户是否为admin。

但是我通过检查日志（数据库中存在记录）将request1的大小设置为0.任何建议 

private boolean isAdmin() throws AppException {
try {
 Session session = PersistenceManager.getSession(); 
 Criteria criteria = session.createCriteria(QuickUrlAdmin.class);
             List<QuickUrl> request1 = null;             
             for (String group : groups) { //groups is a list  filled from another method 
                 log.debug("group:" + group);               
                 request1 =criteria.add(Restrictions.eq("adminUser", group)).list();
                 log.debug(" Request Object :" +request1.size());                
             }
}

直接HQL查询工作正常 

String sql = "SELECT * FROM QuickUrlAdmin WHERE adminUser = :group_name";
             SQLQuery query = session.createSQLQuery(sql);
             query.addEntity(QuickUrlAdmin.class);           
                for (String group : groupList) {
                     log.debug("*********group:" + group);              
                     query.setParameter("group_name", group);
                     List<QuickUrl> results1 = query.list();                
                     log.debug(" Request Object :" +results1.size());
                 }

安库·辛哈尔（Ankur Singhal）

我从你的问题中了解到的是

1.）您有一些名称列表groups。

2）您正在获取QuickUrlAdmin，其中adminUser等于传递的名称。

基本上，您是逐组进行迭代，并且每次都访问数据库。

试试这个，会解决你的目的

SELECT * FROM QuickUrlAdmin WHERE adminUser IN :groups

团体只是那里list of String。

修改后的代码

String sql = "SELECT * FROM QuickUrlAdmin WHERE adminUser IN :groups";
             SQLQuery query = session.createSQLQuery(sql);
             query.addEntity(QuickUrlAdmin.class);           
             query.setParameter("groups", groups);
             List<QuickUrl> results1 = query.list();

标准API

private boolean isAdmin() throws AppException {
try {
 Session session = PersistenceManager.getSession(); 
 Criteria criteria = session.createCriteria(QuickUrlAdmin.class);
             List<QuickUrl> request1 = null;             
             request1 =criteria.add(Restrictions.in("adminUser", groups)).list();
             log.debug(" Request Object :" +request1.size());    
}
