Iii. Development Process 1. Project Structure

Namespace SpringNetDi {public class Product {public string Name {get; set;} public decimal UnitPrice {get; set ;}}}3. Compile ProductFactory. cs

namespace SpringNetDi{    public class ProductFactory    {        public Product FactoryProduct { get; set; }    }}

4. Write Article. cs

Namespace SpringNetDi {public class Article {private string name; private string writer; public Article (string name, string writer) {this. name = name; this. writer = writer;} public void GetMsg () {Console. writeLine ("Hello, I am" + writer );}}}

5. Configure app. config

<? Xml version = "1.0" encoding = "UTF-8"?> <Configuration> <configSections> <sectionGroup name = "spring"> <section name = "context" type = "Spring. context. support. contextHandler, Spring. core "> </section> <section name =" objects "type =" Spring. context. support. defaultSectionHandler, Spring. core "/> </sectionGroup> </configSections> <spring> <context> <resource uri =" config: // spring/objects "> </resource> </context> <objects> <! -- 01 property injection-value type --> <object name = "product" type = "SpringNetDi. product, springNetDi "> <property name =" Name "value =" marker "> </property> <property name =" UnitPrice "value =" 5 "> </property> </object> <! -- 02 property injection-reference type --> <object name = "factory" type = "SpringNetDi. productFactory, SpringNetDi "> <property name =" FactoryProduct "ref =" product "> </property> </object> <! -- 03 constructor injection --> <object name = "article" type = "SpringNetDi. article, springNetDi "> <constructor-arg name =" name "value =" dependency injection "> </constructor-arg> <constructor-arg name =" writer "value =" Kimisme "> </constructor-arg> </object> </objects> </spring> <startup> <supportedRuntime version = "v4.0" sku = ". NETFramework, Version = v4.5 "/> </startup> </configuration>

6. Console code

namespace SpringNetDi{    class Program    {        static void Main(string[] args)        {            IApplicationContext context = ContextRegistry.GetContext();            Product product = context.GetObject("product") as Product;            Console.WriteLine(product.Name);            ProductFactory factory = context.GetObject("factory") as ProductFactory;            Console.WriteLine(factory.FactoryProduct.Name);            Article article = context.GetObject("article") as Article;            article.GetMsg();            Console.WriteLine("ok");        }    }}
