分享Hibernate5为什么在Web工程中报错Java工程中正常运行？
之前试着在Web项目中添加Hibernate5来操作数据库，但是失败了。后来看书跟书上创建了一个Java项目运行没有问题，回到web项目里配置基本基本相同却没有办法正常使用时为什么呀。。。。
Dao代码
项目是Struts+Hibernate
求大神解答。。。。。
Dao代码
public boolean LoginAdmin(String adminName,String adminPwd){
boolean returnValue=false;
final StandardServiceRegistry registry =new StandardServiceRegistryBuilder().configure().build();
SessionFactory sessionFactory = new MetadataSources(registry).buildMetadata().buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction transaction = session.beginTransaction();
String HQL = "select count(*) from Admin where adminName=:name"+"adminPwd=:pwd";
Object obj = session.createQuery(HQL)
.setString("name", adminName)
.setString("pwd", adminPwd)
.list();
System.out.println("obj="+obj);
Long count = obj==null?0:(Long)obj;
if(count>0)
returnValue = true;
transaction.commit();
System.out.println("return Value="+returnValue);
return returnValue;

String HQL = "select count(*) from Admin where adminName=:name"+"adminPwd=:pwd";
缺少空格吧
String HQL = "select count(*) from Admin where adminName=:name"+" adminPwd=:pwd";

应该就是sql语句的问题。
你可以先试试
String HQL = "select count(*) from Admin";
行不行
你的Admin对象的属性里面有 adminName adminPwd吗？
实在不行还可以使用原生sql，语句完全是数据库里面的字段，
createQuery使用createSQLQuery
