了解Spring set依赖注入集合Collections

ApplicationContext.xml
在上下文环境配置文件中对list, map, set, properties进行配置，以提供bean实例

<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsd"><bean id="cur" class="java.util.Date"/><!-- scope="singleton"意味单例工厂模式 --><bean id="userAction" class="cn.com.xalead.spring.UserAction" scope="singleton"><property name="manager"><ref bean="userManager"/></property><property name="list"><list><value>2222</value><ref local="cur"/></list></property><property name="set"><set><value>Hello</value><value>234.22</value><value>22222</value><value type="java.lang.String">true</value></set></property><property name="map"><map><entry key="a1"><value>afasfdsfa</value></entry><entry key="a2"><value>34345</value></entry></map></property><property name="props"><props><prop key="x1">adsfas</prop><prop key="x2">34534</prop></props></property></bean>
</beans>

UserAction.java

这个文件主要是定义变量及生成set方法

import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;public class UserAction{private List list = null;private Set set = null;private Map map = null;private Properties props = null;public List getList() {return list;}public void setList(List list) {this.list = list;}public Set getSet() {return set;}public void setSet(Set set) {this.set = set;}public Map getMap() {return map;}public void setMap(Map map) {this.map = map;}public Properties getProps() {return props;}public void setProps(Properties props) {this.props = props;}private UserManager manager = null;public void setManager(UserManager manager) {this.manager = manager;}
}

运行测试

public static void main(String[] args) {
//      BeanFactory factory = new ClassPathXmlApplicationContext("applicationContext.xml");BeanFactory factory = new ClassPathXmlApplicationContext("app*.xml");
//      BeanFactory fa1 = new XmlBeanFactory(new ClassPathResource("appliactionContext_1.xml"),factory);UserAction ua = (UserAction)factory.getBean("userAction");for(Object o : ua.getList()){System.out.println(o);}System.out.println("--------------------------------------");for(Object o : ua.getSet()){System.out.println(o);}System.out.println("---------------------------------------");for(Iterator iter = ua.getMap().entrySet().iterator() ; iter.hasNext(); ){Entry entry = (Entry)iter.next();System.out.println(entry.getKey() + ":" + entry.getValue());}System.out.println("---------------------------------------");for(Iterator iter = ua.getProps().keySet().iterator(); iter.hasNext(); ){String key = (String)iter.next();System.out.println(key + "：" + ua.getProps().getProperty(key));}}

测试结果
