使用 Unity XML 配置文件在构造函数中注入复杂对象

Question

>我有以下类声明：记录器服务，外观阅读器和业务经理。我想使用 Unity XML 配置在 BusinessManager 中注入 Logger Service 和 FacadeReaderService。

记录器服务

public class LoggerService : ILoggerService
{
}

立面阅读器服务

public class FacadeReaderService : IFacadeReaderService
{
}

业务经理

public class BusinessManager : IBal
    {
        IFacadeReaderService _facadeReaderService;
        ILoggerService _loggerService;
        public BusinessManager(IFacadeReaderService facadeReaderService, ILoggerService loggerService)
        {
            this._facadeReaderService = facadeReaderService;
            this._loggerService = loggerService;
        }
    }

我的问题是如何在我的业务管理器类中注入这个复杂的对象？以下是到目前为止我在 Unity 配置文件中所做的：

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
  <typeAliases>
    <typeAlias alias="IFacadeReaderService" type="Interfaces.Services.IFacadeReaderService, Interfaces" />
    <typeAlias alias="FacadeReaderService" type="Services.FacadeReader.FacadeReaderService, Services" />
    <typeAlias alias="ILoggerService" type="Interfaces.Services.ILoggerService, Interfaces" />
    <typeAlias alias="LoggerService" type="Services.Log.LoggerService, Services" />

    <typeAlias alias="IBal" type="Interfaces.Bal.IBal, Interfaces" />
    <typeAlias alias="BusinessManager" type="Bal.BusinessManager, Bal" />

  </typeAliases>
    <container>
      <register type="IFacadeReaderService" mapTo="FacadeReaderService" name="FRS"/>
      <register type="ILoggerService" mapTo="LoggerService" name="LS"/>
      <register type="IBal" mapTo="BusinessManager" name="BMS">
      <constructor>
        <param name="facadeReaderService" value="????????" />
        <param name="loggerService" value="??????" />
      </constructor>
      </register>
    </container>
</unity>

好吧，我通过查看Microsoft文档找到了问题的答案：https://msdn.microsoft.com/en-us/library/ff660914（v=pandp.20）.aspx#config_value

我将发布 unity 配置，以防万一有人需要它：

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
  <typeAliases>
    <typeAlias alias="IFacadeReaderService" type="Interfaces.Services.IFacadeReaderService, Interfaces" />
    <typeAlias alias="FacadeReaderService" type="Services.FacadeReader.FacadeReaderService, Services" />
    <typeAlias alias="ILoggerService" type="Interfaces.Services.ILoggerService, Interfaces" />
    <typeAlias alias="LoggerService" type="Services.Log.LoggerService, Services" />

    <typeAlias alias="IBal" type="Interfaces.Bal.IBal, Interfaces" />
    <typeAlias alias="BusinessManager" type="Bal.BusinessManager, Bal" />

  </typeAliases>
    <container>
      <register type="IFacadeReaderService" mapTo="FacadeReaderService" name="FRS"/>
      <register type="ILoggerService" mapTo="LoggerService" name="LS"/>
      <register type="IBal" mapTo="BusinessManager" name="BMS">
        <constructor>
          <param name="facadeReaderService">
            <dependency name="FRS" />
          </param>
          <param name="loggerService">
            <dependency name="LS" />
          </param>
        </constructor>
      </register>
    </container>
</unity>
