集合类型的装配

知识点：
【

第一：设置集合属性
public class OrderServiceBean {
private Set<String> sets = new HashSet<String>();
private List<String> lists = new ArrayList<String>();
private Properties properties = new Properties();
private Map<String, String> maps = new HashMap<String, String>();
        ....//这里省略属性的getter和setter方法
}

第二：为是属性设置值

<bean id="order" class="cn.itcast.service.OrderServiceBean">
    <property name="lists">
          <list>
<value>lihuoming</value>
         </list>
      </property>
      <property name="sets">
         <set>
            <value>set</value>
        </set>
      </property>
     <property name="maps">
        <map>
            <entry key="lihuoming" value="28"/>
       </map>
     </property>
     <property name="properties">
        <props>
<prop key="12">sss</prop>
       </props>
      </property>
</bean>

搭建环境见上...

照样实现步骤：

第一步：编写Bean



public class PersonServer implements IPersonServer {

//集合类型的装配

private Set<String> sets = new HashSet<String>();
private List<String> lists = new ArrayList<String>();
private Properties properties = new Properties();
private Map<String, String> maps = new HashMap<String, String>();

//生成getter和setter方法
public Set<String> getSets() {
return sets;
}
public void setSets(Set<String> sets) {
this.sets = sets;
}
public List<String> getLists() {
return lists;
}
public void setLists(List<String> lists) {
this.lists = lists;
}
public Properties getProperties() {
return properties;
}
public void setProperties(Properties properties) {
this.properties = properties;
}
public Map<String, String> getMaps() {
return maps;
}
public void setMaps(Map<String, String> maps) {
this.maps = maps;
}

public PersonServer(){}

public void save()
{
//personDao.add();
Iterator<String> iterator=sets.iterator();
while (iterator.hasNext()) {
String string = (String) iterator.next();
System.out.println(string);
}
System.out.println("---------------------");
Iterator<String> iterator2= lists.iterator();
while (iterator2.hasNext()) {
String string = (String) iterator2.next();
System.out.println(string);
}
Set<Entry<Object, Object>> sets=properties.entrySet();
Iterator<Entry<Object, Object>> iterator3=sets.iterator();
System.out.println("---------------------");
while (iterator3.hasNext()) {
Map.Entry<java.lang.Object, java.lang.Object> entry = (Map.Entry<java.lang.Object, java.lang.Object>) iterator3.next();
System.out.println(entry.getKey()+"="+entry.getValue());
}
System.out.println("---------------------");
Set<Entry<String, String>> mapSet=maps.entrySet();
Iterator<Entry<String, String>> iterator4=mapSet.iterator();
while (iterator4.hasNext()) {
Map.Entry<java.lang.String, java.lang.String> entry = (Map.Entry<java.lang.String, java.lang.String>) iterator4
.next();
System.out.println(entry.getKey()+"="+entry.getValue());
}

}
}

第二步：编写beans.xml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-2.5.xsd"
           default-lazy-init="false">
<bean id="personServer" class="com.liyong.ServersBean.PersonServer">
<property name="sets" >
<set>
<value>set1</value>
<value>set2</value>
</set>
</property>
<property name="lists" >
<list>
<value>list1</value>
<value>list2</value>
</list>
</property>
<property name="properties">
<props>
<prop key="prop1">prop1</prop>
<prop key="prop2">prop2</prop>
<prop key="prop3">prop3</prop>
</props>
</property>
<property name="maps">
<map>
<entry key="map1" value="map1"/>
<entry key="map2" value="map2"/>
<entry key="map3" value="map3"/>
</map>
</property>
</bean>
</beans>

第三步：编写单元测试
public class JUnitTest {

@Test
public void TestSave()
{
//得到Spring容器实例、

ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
//AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
//ApplicationContext ctx2 = new ClassPathXmlApplicationContext(new String[]{"beans.xml"});

//这里面向接口
IPersonServer server =(IPersonServer)ctx.getBean("personServer");
server.save();
}
}

第四步：测试...
