Spring之注入复杂类型属性
注入类：
1 package helloworld; 2 3 import java.util.List; 4 import java.util.Map; 5 import java.util.Properties; 6 7 public class User { 8 private List list; 9 private Map<String, String> map; 10 private Properties pro; 11 12 public void setList(List list) { 13 this.list = list; 14 } 15 16 public void setMap(Map<String, String> map) { 17 this.map = map; 18 } 19 20 public void setPro(Properties pro) { 21 this.pro = pro; 22 } 23 24 public void say() { 25 System.out.println(list); 26 System.out.println(map); 27 System.out.println(pro); 28 } 29 }
beans.xml配置
1 <beans xmlns="http://www.springframework.org/schema/beans" 2 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xmlns:contexnt="http://www.springframework.org/schema/context" 4 xsi:schemaLocation="http://www.springframework.org/schema/beans 5 http://www.springframework.org/schema/beans/spring-beans.xsd 6 http://www.springframework.org/schema/context 7 http://www.springframework.org/schema/context/spring-context-2.5.xsd"> 8 9 <bean id="user" class="helloworld.User"> 10 <property name="list"> 11 <list> 12 <value>aaa</value> 13 <value>bbb</value> 14 <value>ccc</value> 15 </list> 16 </property> 17 <property name="map"> 18 <map> 19 <entry key="a" value="apple"></entry> 20 <entry key="b" value="banner"></entry> 21 </map> 22 </property> 23 <property name="pro"> 24 <props> 25 <prop key="name">Tom</prop> 26 <prop key="age">25</prop> 27 </props> 28 </property> 29 </bean>
测试代码:
1 ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml"); 2 // 参数注入 3 User user = (User) context.getBean("user"); 4 user.say();
