请帮忙

您可以使用此

name=“connection.connection\u string”

：

<session-factory>
    ...
    <property name="connection.connection_string"> 
      Server=localhost;Database=mohit;User ID=root;Password=root
    </property>

// another web.config section "<connectionStrings>"
<connectionStrings>
  <add name="MyName" 
    connectionString="Server=localhost;Database=mohit;User ID=root;Password=root" />
</connectionStrings>

// here we reference the name defined in the other section
<session-factory>
    ...
    <property name="connection.connection_string_name">MyName</property>
