JAVAbean里面连接数据库代码 验证name,password
public boolean userCheck(String name,String password){
Session session = null;
List list = null;
try{
session = HibernateSessionFactory.currentSession();
Query query = session.createQuery("from People where name='"+name+"' and password='"+password+"'");
list = query.list();
Iterator it = list.iterator();
if(it.hasNext()){
return true;
}
else{
return false;
}
}
catch(Exception e){
e.printStackTrace();
return false;
}
}
servlet里面的代码
String name = request.getParameter("name");
String password = request.getParameter("password");
System.out.println("name======="+name);
System.out.println("password==="+password);
下面的过不去
Manager ma = new Manager();
System.out.println("gggggggggggg");
boolean bool = ma.userCheck(name,password);
System.out.println("sssssssssss");
System.out.println("bool===="+bool);
执行时候 弹出window.alert("页面不正常");
