连接被拒绝
问题描述:
我试图使用从CFG文件冬眠连接到MySQL数据库连接被拒绝
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.connection.driver_class">

<property name="hibernate.connection.url">

<property name="hibernate.connection.username">

<property name="hibernate.hbm2ddl.auto">

<!-- Mapping files -->
<mapping resource="Employee.hbm.xml" />
</session-factory>
</hibernate-configuration>
private static SessionFactory factory;
public static void main(String[] args) {
try {
factory = new Configuration().configure().buildSessionFactory();
} catch (Throwable ex) {
System.err.println("Failed to create sessionFactory object." + ex);
ex.fillInStackTrace();
ex.printStackTrace();
throw new ExceptionInInitializerError(ex);
}
虽然我的连接字符串,用户名,密码是否正确,同样是工作与基本JDBC连接其他项目很好,但是当我尝试使用Hibernate我在控制台上
Exception in thread "main" java.lang.ExceptionInInitializerError
at com.hibernate.ManageEmployee.main(ManageEmployee.java:21)
Caused by: org.hibernate.HibernateException: Could not parse configuration: /hibernate.cfg.xml
at com.hibernate.ManageEmployee.main(ManageEmployee.java:19)

at com.hibernate.ManageEmployee.main(ManageEmployee.java:16)
收到此错误它是的数据库服务器启动并运行,但是从这个Hibernate应用程序的连接将被拒绝
答
问题是xml解析器试图访问配置文件中指定的模式文件。您可以在哪里运行程序,访问互联网?
下面是一些额外的信息:
你创建了测试数据库的密码。如果没有为测试数据库创建密码 – pudaykiran
没有提到hibernate正在尝试连接你的堆栈跟踪(只是配置)。我猜想你的XML解析器试图连接某处以获取DTD/XSD进行验证。可以提供全栈跟踪?另外检查这一个http://*.com/questions/17114046/hibernate-error-possibly-with-dtd-declaration – rkosegi
