Spring的DI(Ioc) - 注入集合类型

1： 首先给service添加集合类型的属性，并提供getter, setter

package cn.gbx.serviceimpl;



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.gbx.daoimpl.PersonDao;

import cn.gbx.service.PersonService;



public class PersonServiceImpl implements PersonService {

	private Set<String> sets = new HashSet<String>();

	private List<String> list = new ArrayList<String>();

	private Map<String, String> maps = new HashMap<String, String>();

	private Properties properties = new Properties();

	

	

	private PersonDao personDao;

	private String name;

	private Integer id;

	

	

	public void save() {

		System.out.println("id = " + id + "name = " + name);

		personDao.save();

		System.out.println("service :  " + " save 方法");

	}

	

	public PersonDao getPersonDao() {

		return personDao;

	}

	public void setPersonDao(PersonDao personDao) {

		this.personDao = personDao;

	}



	public String getName() {

		return name;

	}



	public void setName(String name) {

		this.name = name;

	}



	public Integer getId() {

		return id;

	}



	public void setId(Integer id) {

		this.id = id;

	}



	public Set<String> getSets() {

		return sets;

	}



	public void setSets(Set<String> sets) {

		this.sets = sets;

	}



	public List<String> getList() {

		return list;

	}



	public void setList(List<String> list) {

		this.list = list;

	}



	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;

	}

	

}

　　

2: 配置xml文件

<?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="personDaoImpl" class="cn.gbx.dao.PersonDaoImpl"></bean>

 	<bean id="personServiceImpl" class="cn.gbx.serviceimpl.PersonServiceImpl" >

 		<property name="personDao" ref="personDaoImpl"></property>

 		<property name="name" value="ok-gbx"></property>

 		<property name="id" value="22"></property>

 		

 		<property name="list">

 			<list>

 				<value>valu1</value>

 				<value>valu2</value>

 				<value>valu3</value>

 			</list>

 		</property>

 		

 		<property name="sets">

	 		<set>

	 			<value>value-1</value>

	 			<value>value-2</value>

	 			<value>value-3</value>

	 		</set>

 		</property>

 		

 		<property name="maps">

 			<map>

 				<entry key="key1" value="value1"></entry>

 				<entry key="key2" value="value2"></entry>

 				<entry key="key3" value="value3"></entry>

 			</map>

 		</property>

 		

 		<property name="properties">

 			<props>

 				<prop key="key1">value1</prop>

 				<prop key="key2">value2</prop>

 				<prop key="key3">value3</prop>

 			</props>

 		</property>

 	</bean>

</beans>

　　

3： 测试：

public class SpringTest {

	@Test

	public void spring1() {

		ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");

		PersonService ps = (PersonService)ctx.getBean("personServiceImpl");

		ps.save();

		System.out.println("--------List-------------");

		for (String s : ps.getList()) {

			System.out.println(s);

		}

		System.out.println("--------sets-------------");

		for (String s : ps.getSets()) {

			System.out.println(s);

		}

		

		System.out.println("--------maps-------------");

		for (String key : ps.getMaps().keySet()) {

			System.out.println(key + " : " + ps.getMaps().get(key));

		}

		

		System.out.println("--------propertis-------------");

		for (Object key : ps.getProperties().keySet()) {

			System.out.println(key + " : " + ps.getMaps().get(key));

		}

		

	}

	

	@Test

	public void spring2() {

		MyClassPathXmlApplicationContext ctx = new MyClassPathXmlApplicationContext("beans.xml");

		PersonService ps = (PersonService)ctx.getBean("personServiceImpl");

		ps.save();

		System.out.println();

	}

}
