Spring.Net学习笔记(4)-属性及构造器注入

一、开发环境

二、涉及程序集

三、开发过程

1.项目结构

2.编写Product.cs

namespace SpringNetDi
{
public class Product
{
public string Name { get; set; }

public decimal UnitPrice { get; set; }
}
}

3.编写ProductFactory.cs

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

4.编写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("你好，我是" + writer);
}
}
}

5.配置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属性注入-值类型-->
<object name =" product" type="SpringNetDi.Product,SpringNetDi">
<property name="Name" value="记号笔"></property>
<property name="UnitPrice" value="5"></property>
</object>
<!--02属性注入-引用类型-->
<object name="factory" type="SpringNetDi.ProductFactory,SpringNetDi">
<property name="FactoryProduct" ref="product"></property>
</object>
<!--03构造函数注入-->
<object name="article" type="SpringNetDi.Article,SpringNetDi">
<constructor-arg name="name" value="依赖注入"></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.控制台代码

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");
}
}
}
