set注入

顾名思义set注入必须要有set方法。

基本类型的注入、引用类型注入、List注入、Set注入、Map注入、Properties注入

 public class person {
     private car c;
     private pay p;
     private List list;
     private Set set;
     private Map map;
     private Properties prop;

     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 getProp() {
         return prop;
     }
     public void setProp(Properties prop) {
         this.prop = prop;
     }
     public car getC() {
         return c;
     }
     public void setC(car c) {
         this.c = c;
     }
     public pay getP() {
         return p;
     }
     public void setP(pay p) {
         this.p = p;
     }
     @Override
     public String toString() {
         return "person [c=" + c + ", p=" + p + ", list=" + list + ", set="
                 + set + ", map=" + map + ", prop=" + prop + "]";
     }

 }

XML：

 <!-- 要先创建引用类型的对象 -->
 <bean id="car" class="DI.car"></bean>
 <bean id="pay" class="DI.pay"></bean>

 <bean id="person" class="DI.person">
     <!-- name 是有set方法猜测出的结果 ，ref是上面bean的id值 -->
     <property name="c" ref="car"></property>
     <property name="p" ref="pay"></property>
     <property name="list">
         <list>
             <value>啊啊啊啊啊</value>
             <value>啊啊啊啊啊1</value>
             <value>啊啊啊啊啊2</value>
         </list>
     </property>
     <property name="map">
         <map>
             <entry key="1" value="我"></entry>
             <entry key="2" value="你"></entry>
             <entry key="3" value="她"></entry>
         </map>
     </property>
     <property name="set">
         <set>
             <value>java</value>
             <value>javaaaaaaaaaa</value>
             <value>java</value>
         </set>
     </property>
     <property name="prop">
         <props>
             <prop key="1">我们</prop>
             <prop key="2">你们</prop>
             <prop key="3">她们</prop>
         </props>
     </property>
 </bean>

测试类：

 @Test
     public void test(){

         ApplicationContext cont = new ClassPathXmlApplicationContext("applicationContext.xml");
         person p = (person) cont.getBean("person");
         System.out.println(p);
     }

结果：
