就是类中的属性是集合,对这种属性进行装配,用的更少。配置例子如下:
我的例子:
UserDAOImpl
1 package com.bjsxt.dao.impl; 2 3 import java.util.List; 4 import java.util.Map; 5 import java.util.Set; 6 7 import com.bjsxt.dao.UserDAO; 8 import com.bjsxt.model.User; 9 10 public class UserDAOImpl implements UserDAO{ 11 12 private Set<String> sets; 13 14 private List<String> lists; 15 16 private Map<String,String> maps; 17 18 public void save(User u) { 19 System.out.println("a user saved!"); 20 } 21 22 public Set<String> getSets() { 23 return sets; 24 } 25 26 public void setSets(Set<String> sets) { 27 this.sets = sets; 28 } 29 30 public List<String> getLists() { 31 return lists; 32 } 33 34 public void setLists(List<String> lists) { 35 this.lists = lists; 36 } 37 38 public Map<String, String> getMaps() { 39 return maps; 40 } 41 42 public void setMaps(Map<String, String> maps) { 43 this.maps = maps; 44 } 45 46 public String toString(){ 47 return "sets size:" + sets.size() + "| lists size:" + lists.size() + "| maps size:" + maps.size(); 48 } 49 50 }
beans.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://www.springframework.org/schema/beans 5 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> 6 7 <bean name="u" class="com.bjsxt.dao.impl.UserDAOImpl"> 8 <property name="sets"> 9 <set> 10 <value>1</value> 11 <value>2</value> 12 </set> 13 </property> 14 <property name="lists"> 15 <list> 16 <value>1</value> 17 <value>2</value> 18 <value>3</value> 19 </list> 20 </property> 21 <property name="maps"> 22 <map> 23 <entry key="1" value="1"></entry> 24 <entry key="2" value="2"></entry> 25 <entry key="3" value="3"></entry> 26 <entry key="4" value="4"></entry> 27 </map> 28 </property> 29 </bean> 30 31 <bean id="userService" class="com.bjsxt.service.UserService" scope="prototype"> 32 <!-- 33 <property name="userDAO"> 34 <ref bean="u"/> 35 </property> 36 --> 37 <constructor-arg> 38 <ref bean="u"/> 39 </constructor-arg> 40 </bean> 41 </beans>
UserServiceTest
1 package com.bjsxt.service; 2 3 import org.junit.Test; 4 import org.springframework.context.ApplicationContext; 5 import org.springframework.context.support.ClassPathXmlApplicationContext; 6 7 import com.bjsxt.dao.UserDAO; 8 import com.bjsxt.dao.impl.UserDAOImpl; 9 10 public class UserServiceTest { 11 12 @Test 13 public void testAddUser() throws Exception { 14 ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");//初始化ApplicationContext对象,加载配置文件 15 16 UserDAO u1 = (UserDAOImpl)ctx.getBean("u"); 17 System.out.println(u1); 18 } 19 20 }
