Spring入门(03)-依赖注入-set方法注入

对象注入： 

方法一：

<bean id="personDao" class="com.hx.springdemo01.dao.impl.PersonDaoImpl"/>
     <bean id="personService" class="com.hx.sprindemo01.service.impl.PersonServiceImpl">
       <property name="personDao" ref="personDao"></property>
     </bean>

方法二：

  <bean id="personService" class="com.hx.sprindemo01.service.impl.PersonServiceImpl">
       <property name="personDao">
        <bean class="com.hx.springdemo01.dao.impl.PersonDaoImpl"></bean>
       </property>
     </bean>

基本数据注入：

<property name="name" value="thanks"></property>

集合类型注入：

实现类中 集合的get和set方法，接口中get方法

-------------------------------set-------------------------------

 <property name="sets">
            <set>
             <value>第一个</value>
             <value>第二个</value>
             <value>第s个</value>
           </set>
        </property>

 

 for(String value: personService.getLists()){
         System.out.println(value);
        }

-------------------------------list-------------------------------
        <property name="lists">
          <list>
           <value>第1个</value>
           <value>第2个</value>
           <value>第3个</value>
          </list>
        </property>

for(String s:personService.getLists()){
         System.out.println(s);
        }

 

-------------------------------properties-------------------------------
        <property name="properties">
            <props>
              <prop key="one">one</prop>
              <prop key="two">two</prop>
              <prop key="three">three</prop>
            </props>
        </property>

for(Object key:personService.getProperties().keySet()){
         System.out.println("key-->"+key+" value-->"+personService.getProperties().getProperty((String)key));
        }

 

-------------------------------map-------------------------------
        <property name="map">
           <map>
             <entry key="key1" value="value1"></entry>
             <entry key="key2" value="value2"></entry>
             <entry key="key3" value="value3"></entry>
           </map>
        </property>

 for(String key:personService.getMap().keySet()){
         System.out.println("key-->"+key+" value-->"+personService.getMap().get(key));
        }
