Spring.NET依赖注入框架学习---实例化容器常用方法
本篇学习实例化Spring.NET容器的俩种方式
1、通过XmlObjectFactory创建一个Spring.NET容器
IResource input = new FileSystemResource ("objects.xml"); IObjectFactory factory = new XmlObjectFactory(input);
这样就可以通过factory的GetObject(“objectName”);获取这个对象
2、通过IApplicationContext创建一个Spring.NET容器
IApplicationContext ctx = ContextRegistry.GetContext();
这样就可以通过IApplicationContext的GetObject(“objectName”);获取这个对象
程序例子
例子代码：Person.cs
namespace Spring.NET01 { public class Person { public Person() { } ~Person() { } public void print() { Console.WriteLine("我是一个Person对象"); } } }
App.config文件
<?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> <!--元数据对象的来源--> <resource uri="config://spring/objects"></resource> </context> <objects xmlns="http://www.springframework.net"> <!--一个person对象--> <object id="person1" type="Spring.NET01.Person,Spring.NET01"> </object> </objects> </spring> </configuration>
添加objects.xml 其中objects 的属性值必须加上
<?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="person2" type="Spring.NET01.Person,Spring.NET01"> </object> </objects>
测试代码：
class Program { static void Main(string[] args) { //普通对象创建 Console.WriteLine("--------普通对象创建方法--------"); Person person = new Person(); person.print(); //通过Spring.NET ioc IApplicationContext注入对象 Console.WriteLine("--------IApplicationContext方法--------"); IApplicationContext content = ContextRegistry.GetContext(); Person bennanhai = (Person)content.GetObject("person1"); bennanhai.print(); //通过Spring.NET ioc XmlObjectFactory注入对象 Console.WriteLine("--------XmlObjectFactory方法--------"); IResource input = new FileSystemResource("objects.xml"); IObjectFactory factory = new XmlObjectFactory(input); Person bennanhai2 = (Person)factory.GetObject("person2"); bennanhai2.print(); Console.Read(); } }
运行结果
