实体框架Web配置文件

Question

这段代码工作正常:

<connectionStrings>
    <add name="EFDbContext" connectionString="Data Source=.\SQLEXPRESS; Initial Catalog=myDB;Integrated Security=SSPI;
 " providerName="System.Data.SqlClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="Data Source=.\SQLEXPRESS; Integrated Security=True; MultipleActiveResultSets=True" />
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>

但是这段代码不起作用:

<connectionStrings>
    <add name="EFDbContext" connectionString="Data Source=.\MSSQLSERVER2008; Initial Catalog=myDb;Integrated Security=SSPI;User ID=useradmin; Password=pass; " providerName="System.Data.SqlClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="Data Source=.\MSSQLSERVER2008; Integrated Security=True; MultipleActiveResultSets=True" />
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>

第二个代码必须在具有MSQSERVER2008实例的远程服务器上运行,并且在加载页面时,将显示以下消息:

从数据库获取提供程序信息时发生错误.这可能是由实体框架使用不正确的连接字符串引起的.检查内部异常以获取详细信息,并确保连接字符串正确.

Answer 1

问题在于Integrated Security参数.当它设置为True时,如果您指定用户和密码,.Net会尝试打开与当前用户事件的连接.因此,要打开与特定用户的连接,请将Integrated Security设置为False,它将起作用.

<connectionStrings>
    <add name="EFDbContext" connectionString="Data Source=.\MSSQLSERVER2008; Initial Catalog=myDb;Integrated Security=SSPI;User ID=useradmin; Password=pass; " providerName="System.Data.SqlClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="Data Source=.\MSSQLSERVER2008; Integrated Security=False; MultipleActiveResultSets=True" />
      </parameters>
    </defaultConnectionFactory>
  </entityFramework>
