spring集合Collection注入

1、BookDao接口和实现类

public interface BookDao {void save();
}
public class BookDaoImpl implements BookDao {private int[] array;private List<String> list;private Set<String> set;private Map<String,String> map;private Properties properties;public void setArray(int[] array) {this.array = array;}public void setList(List<String> list) {this.list = list;}public void setSet(Set<String> set) {this.set = set;}public void setMap(Map<String, String> map) {this.map = map;}public void setProperties(Properties properties) {this.properties = properties;}public void save(){System.out.println("book dao save......" );System.out.println("遍历数组:"+ Arrays.toString(array));System.out.println("遍历List"+ list);System.out.println("遍历Set"+ set);System.out.println("遍历Map"+ map);System.out.println("遍历Properties"+ properties);}
}

2、配置文件

<?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.xsd"><bean id="bookDao" class="com.itheima.dao.impl.BookDaoImpl" ><property name="array" ><array><value>100</value><value>200</value><value>300</value></array></property><property name="list"><list><value>itcast</value><value>itheima</value><value>itjava</value></list></property><property name="set"><set><value>java</value><value>php</value><value>golang</value><value>golang</value><value>c++</value></set></property><property name="map"><map><entry key="country" value="China"/><entry key="province" value="Henan"/><entry key="city" value="Kaifeng"/></map></property><property name="properties"><props><prop key="country">china</prop><prop key="province">Henan</prop><prop key="city">Kaifeng</prop></props></property></bean>
</beans>

3、使用方法

 public static void main(String[] args) {ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");BookDao bookDao = (BookDao) ctx.getBean("bookDao");bookDao.save();}
