1.创建Maven项目,项目名称springdemo32,如图所示
![QQ截图20170324115303.png Spring4-MapFactoryBean的使用_Map](https://s2.51cto.com/wyfs02/M01/8F/21/wKioL1jUmE_j1rKoAAA-GqRshxY793.png?x-oss-process=image/resize,m_fixed,w_1184)
2.配置Maven,修改项目中的pom.xml文件,修改内容如下
<project xmlns="http://maven.apache.org/POM/4.0.0"

3.在src/main/java下创建实体Bean Forum,包名(com.mycompany.shequ.bean)如图所示
![QQ截图20170324115403.png Spring4-MapFactoryBean的使用_Factory_02](https://s2.51cto.com/wyfs02/M02/8F/23/wKiom1jUmIuiOT6xAABI4Uj43IM141.png?x-oss-process=image/resize,m_fixed,w_1184)
4.实体Bean Forum的内容如下
package com.mycompany.shequ.bean;
import java.util.Map;
public class Forum {
private int fid;
private String name;
private Map<Object,Object> maps;
public int getFid() {
return fid;
}
public void setFid(int fid) {
this.fid = fid;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Map<Object, Object> getMaps() {
return maps;
}
public void setMaps(Map<Object, Object> maps) {
this.maps = maps;
}
@Override
public String toString() {
return "{fid=>"+this.fid+",name=>"+this.name+"}";
}
}
5.在src/main/resources下创建spring-bean.xml配置文件,如图所示
![QQ截图20170324115502.png Spring4-MapFactoryBean的使用_Factory_03](https://s2.51cto.com/wyfs02/M02/8F/21/wKioL1jUmMXjDuhUAABKtAXuAg4183.png?x-oss-process=image/resize,m_fixed,w_1184)
6.spring-bean.xml配置文件的内容如下
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-4.0.xsd">
<bean id="forum" class="com.mycompany.shequ.bean.Forum">
<property name="fid" value="1"></property>
<property name="name" value="set集合"></property>
<property name="maps">
<bean class="org.springframework.beans.factory.config.MapFactoryBean">
<property name="targetMapClass">
<value>java.util.HashMap</value>
</property>
<property name="sourceMap">
<map>
<entry key="key1" value="value1"></entry>
<entry key="key2" value="value2"></entry>
<entry key="key3" value="value3"></entry>
</map>
</property>
</bean>
</property>
</bean>
</beans>
7.在src/main/resources下创建核心配置文件applicationContext.xml,如图所示
![QQ截图20170324115555.png Spring4-MapFactoryBean的使用_Spring4_04](https://s2.51cto.com/wyfs02/M00/8F/23/wKiom1jUmP3A4S11AABGivBmSXY342.png?x-oss-process=image/resize,m_fixed,w_1184)
8.核心配置文件applicationContext.xml的内容如下
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
<import resource="bean/spring-bean.xml"/>
</beans>
9.在src/test/java下创建测试文件AppTest,包名(com.mycompany.shequ.test)如图所示
![QQ截图20170324115645.png Spring4-MapFactoryBean的使用_Map_05](https://s2.51cto.com/wyfs02/M01/8F/23/wKiom1jUmS2AUUj2AABJXujO0EY168.png?x-oss-process=image/resize,m_fixed,w_1184)
10.测试文件AppTest的内容如下
package com.mycompany.shequ.test;
import java.util.Map;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mycompany.shequ.bean.Forum;
public class AppTest {
@Test
public void beanTest(){
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Forum forum = (Forum) context.getBean("forum");
Map<Object,Object> maps = forum.getMaps();
for(Object key:maps.keySet()){
System.out.println(key+"=>"+maps.get(key));
}
}
}
11.在测试类AppTest的beanTest方法上右键运行,输出结果如图所示
