spring集合類型裝配

1.beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<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-2.5.xsd">
          <bean id="personService" class="cn.zoe.service.impl.PersonServiceBean">
          	<property name="sets">
          		<set>
          			<value>第一個</value>
          			<value>第二個</value>
          			<value>第三個</value>
          		</set>
          	</property>
          	<property name="lists">
          		<list>
          			<value>第一個list元素</value>
          			<value>第二個list元素</value>
          			<value>第三個list元素</value>
          		</list>
          	</property>
          	<property name="properties">
          		<props>
          			<prop key="key1">value1</prop>
          			<prop key="key2">value2</prop>
          			<prop key="key3">value3</prop>
          		</props>
          	</property>
          	<property name="maps">
          		<map>
          			<entry key="key-1" value="value-1"/>
          			<entry key="key-2" value="value-2"/>
          			<entry key="key-3" value="value-3"/>
          		</map>
          	</property>
          </bean>
</beans>

2.接口PersonService.java

package cn.zoe.service;

import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

public interface PersonService {
	public Set<String> getSets();
	public void save();
	public List<String> getLists();
	public Properties getProperties() ;
	public Map<String, String> getMaps();

}

3.實現類PersonServiceBean.java

package cn.zoe.service.impl;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;

import cn.zoe.service.PersonService;

public class PersonServiceBean implements PersonService {
	private Set<String> sets = new HashSet<String>();
	private List<String> lists = new ArrayList<String>();
	private Properties properties = new Properties();
	private Map<String, String> maps = new HashMap<String, String>();
	
	public Map<String, String> getMaps() {
		return maps;
	}

	public void setMaps(Map<String, String> maps) {
		this.maps = maps;
	}

	public Properties getProperties() {
		return properties;
	}

	public void setProperties(Properties properties) {
		this.properties = properties;
	}

	public Set<String> getSets() {
		return sets;
	}

	public void setSets(Set<String> sets) {
		this.sets = sets;
	}

	public List<String> getLists() {
		return lists;
	}

	public void setLists(List<String> lists) {
		this.lists = lists;
	}

	public void save(){
		
	}
}

4.測試類

package junit.test;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.zoe.service.PersonService;

public class SpringTest {

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
	}

	@Test public void instanceSpring(){
		AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
		PersonService personService = (PersonService)ctx.getBean("personService");
		System.out.println("========set===========");
		for(String value : personService.getSets()){
			System.out.println(value);
		}
		System.out.println("========list===========");
		for(String value : personService.getLists()){
			System.out.println(value);
		}
		System.out.println("========properties===========");
		for(Object key : personService.getProperties().keySet()){
			System.out.println(key+"="+ personService.getProperties().getProperty((String)key));
		}
		System.out.println("========map===========");
		for(String key : personService.getMaps().keySet()){
			System.out.println(key+"="+ personService.getMaps().get(key));
		}
		ctx.close();
		
	}
}
