休眠标准不从数据库中检索数据

Question

嗨，我是 Hibernate 的新手，因为我正在使用标准从数据库中检索数据，但如果记录也匹配，我无法获取数据。下面是我使用的代码sn-p。下面的方法主要是通过与（adminUser列的QuickUrlAdmin表）比较来检查列表（组）中的用户是否为admin。

但我通过检查日志将 request1 大小设为 0（数据库中存在记录）。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());
                 }

Answer 1

我从你的问题中了解到的是

1.) 你有一些名字列表，groups。

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

基本上，您是在组上逐个迭代并每次都访问数据库。

试试这个，会解决你的目的

SELECT * FROM QuickUrlAdmin WHERE adminUser IN :groups

其中 groups 就是 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());    
}
