Spring配置通过静态工厂方法创建的bean

简单的写个类

1 <bean id="staticFactory" class="com.neuedu.bean.StaticFactory" factory-method="getBook">
2     <constructor-arg>
3         <value>book2</value>
4     </constructor-arg>
5   </bean>

applicationContext.xml中进行如下配置

 1 package com.neuedu.bean;
 2 
 3 import java.util.HashMap;
 4 import java.util.Map;
 5 
 6 public class InstanceFactory {
 7     private static Map<String,Book> map=null;
 8     static{
 9         map=new HashMap<String,Book>();
10         map.put("book1",new Book("asdas", 20.0));
11         map.put("book2", new Book("cxvxcv", 110.3));
12     }
13     
14     public static Book getBook(String id) {
15         return map.get(id);
16     }
17 
18 }
