告诉StructureMap使用特定的构造 [英] Tell StructureMap to use a specific constructor
问题描述
我有需要的XPathDocument
两项服务。我希望能够定义 XPathDocumnet
命名实例在两个服务的配置中使用。我也希望能够告诉StuctureMap使用哪个的XPathDocument
的构造函数。当我试图让的XPathDocument
的一个实例,它告诉我,它无法找到的XmlReader
堵塞的类型。我想使用需要的XML文件中的字符串URI的构造。我似乎无法得到这个工作。这里是StructureMap的配置代码
公共类服务1:IService1 {
公共服务1(XPathDocument的文档){}
}
公共类服务2:IService2 {
公共服务2(XPathDocument的文档){}
}
公共类Registry1:注册表{
ForRequestedType< ; IService1方式>()TheDefault.Is.OfConcreteType&所述;服务1>()
.CtorDependency&所述; XPathDocument的>()
。就是(X => x.TheInstanceNamed(XPathDocument1));
ForRequestedType< IService2>()TheDefault.Is.OfConcreteType<客服2>()
.CtorDependency< XPathDocument的>()
。是(X => x.TheInstanceNamed(XPathDocument2 ));
ForRequestedType&所述; XPathDocument的方式>()AddInstances(X => {
x.OfConcreteType&所述; XPathDocument的>()
.WithCtorArg(URI)EqualToAppSetting(XmlFile1。 )
.WithName(XPathDocument1);
x.OfConcreteType<&的XPathDocument GT;()
.WithCtorArg()。EqualToAppSetting(URI XmlFile2)
.WithName (XPathDocument2);
});
}
看的this 。总之,你需要修改 OfConcreteType<服务1>()
到 ConstructedBy(()=>新建服务1());
。
I have two services that require an XPathDocument
. I want to be able to define named instances of XPathDocumnet
to use in the configuration of the two services. I also want to be able to tell StuctureMap which constructor of XPathDocument
to use. When I try to get an instance of XPathDocument
it tells me that it can't find the plugged type for XmlReader
. I want to use the constructor that requires a string uri for the xml file. I cannot seem to get this to work. Here is the StructureMap configuration code.
public class Service1 : IService1 {
public Service1(XPathDocument document) {}
}
public class Service2 : IService2 {
public Service2(XPathDocument document) {}
}
public class Registry1 : Registry {
ForRequestedType<IService1>().TheDefault.Is.OfConcreteType<Service1>()
.CtorDependency<XPathDocument>()
.Is(x => x.TheInstanceNamed("XPathDocument1"));
ForRequestedType<IService2>().TheDefault.Is.OfConcreteType<Service2>()
.CtorDependency<XPathDocument>()
.Is(x => x.TheInstanceNamed("XPathDocument2"));
ForRequestedType<XPathDocument>().AddInstances(x => {
x.OfConcreteType<XPathDocument>()
.WithCtorArg("uri").EqualToAppSetting("XmlFile1")
.WithName("XPathDocument1");
x.OfConcreteType<XPathDocument>()
.WithCtorArg("uri").EqualToAppSetting("XmlFile2")
.WithName("XPathDocument2");
});
}
Look at this. In short, you need to change OfConcreteType<Service1>()
to ConstructedBy(() => new Service1());
.
