休眠SQL Server连接

Question

I am using hibernate to connect to the Microsoft SQL Server which is remotely installed. In the hibernate.cfg.xml file I have the following properties set:

<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
    <property name="hibernate.connection.url">jdbc:sqlserver://machine:1433;databaseName=databaseName;</property>
    <property name="hibernate.connection.username">user</property>
    <property name="hibernate.connection.password">password</property>

The error message that I get in the log file is

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'user'. ClientConnectionId:cb5b8f60-5b4a-41ec-b67c-0784dc7f5d8f

Can someone please guide me as to what is going wrong?

Thanks Raj

Answer 1

Code for creating session factory for hibernate framework using hibernate.cfg.xml

private static SessionFactory factory;
public void init() {
    try {
        Configuration cfg = new Configuration().configure("hibernate.cfg.xml");

        factory = cfg.buildSessionFactory();

    } catch (Throwable ex) {
        System.err.println("Failed to create sessionFactory object." + ex);
        throw new ExceptionInInitializerError(ex);
    }
}

Actual `hibernate.cfg.xml' content which need to add as resource in resource folder.

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- JDBC Database connection settings -->
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="connection.url">jdbc:sqlserver://localhost;port=1433;databaseName=XYZDb;instanceName=SQLEXPRESS;</property>
        <property name="connection.username">user</property>
        <property name="connection.password">password</property>
        <!-- JDBC connection pool settings ... using built-in test pool -->
        <property name="connection.pool_size">1</property>
        <!-- Select our SQL dialect -->
        <property name="dialect">org.hibernate.dialect.SQLServer2012Dialect</property>
        <!-- Echo the SQL to stdout -->
        <property name="show_sql">true</property>
        <!-- Set the current session context -->
        <property name="current_session_context_class">thread</property>

        <!-- dbcp connection pool configuration -->
        <property name="dbcp.initialSize">5</property>
        <property name="dbcp.maxTotal">20</property>
        <property name="dbcp.maxIdle">10</property>
        <property name="dbcp.minIdle">5</property>
        <property name="dbcp.maxWaitMillis">-1</property>
    </session-factory>
</hibernate-configuration>

Make sure below point

• Used correct dialect according to your sql server version
• Provided correct port, databasename , username and password

Answer 2

Did you test your user name and password ? Exception tells that "Login failed for user 'user'." that means you have a connection to the server but given user name and password is not correct.
