一,配置文件进行Spring初始化 1,配置文件编写 <?xml version="1.0" encoding="utf-8" ?> <configuration> /************* 这里会报异常“Spring.Context.Support.ContextRegistry”的类型初始值设定项引发异常。把配置注释掉就行了 <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" /> </startup> ***************/ <configSections> //初始化Spring <sectionGroup name="spring"> <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core" /> <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" /> </sectionGroup> </configSections> //Spring配置节点 <spring> <context> <resource uri="config://spring/objects" /> </context> <objects xmlns="http://www.springframework.net"> <description>人类</description> <object id="Model" type="Model.Person, Model" /> </objects> </spring> </configuration>
2,初始化代码
异常:No object named ‘Person‘ is defined : Cannot find definition for object [Person]
static void Main(string[] args) { IApplicationContext ctx = ContextRegistry.GetContext(); IPerson dao = ctx.GetObject("Person") as IPerson; }
这里报异常是因为在配置文件中没有找到 <object id="Person" type="Model.Person, Model" /> 的节点
需在项目中增加Spring.Core.dll的引用
二,使用Xml文件Spring初始化
(1)具体文件的初始化
编写Objects.xml
<?xml version="1.0" encoding="utf-8" ?> <objects xmlns="http://www.springframework.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.net http://www.springframework.net/xsd/spring-objects.xsd"> <object id="Person" type="Model.Person, Model"> </object> </objects>
后台初始化
private static void ReadFromXml() { IResource input = new FileSystemResource("Objects.xml"); //路径----这里使用的是相对路径,也可以使用绝对路径,如果路径错了会报异常 IObjectFactory factory = new XmlObjectFactory(input); IPerson person = factory.GetObject("Person") as IPerson; person.Speak("hello"); }
(2)程序集下寻找配置文件
private static void ReadFromMuiltDoc() { //需满足URI语法。 //file://文件名 //assembly://程序集名/命名空名/文件名 string[] xmlFiles = new string[] { "file://Objects.xml" }; IApplicationContext context = new XmlApplicationContext(xmlFiles); IObjectFactory factory = (IObjectFactory)context; IPerson person = factory.GetObject("Person") as IPerson; person.Speak("多文件初始化"); }
这种方式相对灵活
(3)在配置文件App.config或Web.config添加自定义配置节点
在配置文件中要引入<objects xmlns="http://www.springframework.net"/>命名空间,否则程序将会无法实例化Spring.NET容器。
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="spring"> <section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core" /> <section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" /> </sectionGroup> </configSections> <spring> <context> <resource uri="assembly://FirstSpringNetApp/FirstSpringNetApp/Objects.xml"/> <resource uri="config://spring/objects" /> </context> <objects xmlns="http://www.springframework.net"/> <!--必要--> </spring>
