  <bean id="chinese" class="Bean.collections.Chinese">
    <!--List 注入例子-->
    <property name="schools">    
      <list>
         <value>小学</value>
         <value>中学</value>
         <value>大学</value>
      </list>

    <!--Properties 注入例子-->
    <property name="health">

         <prop key="血压">正常</prop>
         <prop key="身高">178</prop>
       </props>
    </property>
    <!--Map 注入例子-->
    <property name="scores">
      <map>
        <entry key="数学">
           <value>88</value>
        </entry>
        <entry key="语文">
           <value>99</value>
        </entry>
      </map>
    </property>

 

<!--Map 例子-->

 <bean id="accountConfig" class="java.util.HashMap">
  <constructor-arg>
   <map>
    <entry key="accountResourceSQL">
     <value>SELECT * FROM ABC</value>
    </entry>
   </map>
  </constructor-arg>
 </bean>

 

    <!-Set 注入例子-->
    <property name="axes">
      <set>
        <value>字符串斧子</value>
        <!-- 用嵌套bean定义属性 -->
        <bean class="Bean.collections.WoodAxe"/>
        <!-- 引用bean作为属性 -->
        <ref local="steelaxe"/>
      </set>
    </property>

  <!--array 注入例子-->

  <property name="array">   
   <list>   
    <value>array1</value>   
    <value>array2</value>   
   </list>   
  </property> 
  </bean>
  <bean id="steelaxe" class="Bean.collections.SteelAxe"></bean>
</beans>

实例java代码：

package Bean.collections;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Properties;
import java.util.Set;
import Bean.collections.Person;
public class Chinese implements Person {
    private List schools=new ArrayList();
    private Map scores=new HashMap();
    private Properties health=new Properties();
    private Set axes=new HashSet();
    public Set getAxes() {
        return axes;
    }
    public void setAxes(Set axes) {
        this.axes = axes;
    }
    public Properties getHealth() {
        return health;
    }
    public void setHealth(Properties health) {
        this.health = health;
    }
    public List getSchools() {
        return schools;
    }
    public void setSchools(List schools) {
        this.schools = schools;
    }
    public Map getScores() {
        return scores;
    }
    public void setScores(Map scores) {
        this.scores = scores;
    }
    public void useAxe() {
        System.out.println(schools);
        System.out.println(scores);
        System.out.println(axes);
        System.out.println(health);
    }

}

jdbc.properties配置文件实例：

/WEB-INF/jdbc.properties

jdbc.driver=org.postgresql.Driver   
jdbc.url=jdbc:postgresql://localhost/test   
jdbc.user=postgres   
jdbc.password=  

Bean配置如下：

 

<bean id="propertyConfigurer"  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">   
    <property name="location">   
        <value>/WEB-INF/jdbc.properties</value>   
    </property>   
</bean> 

或者使用多个配置文件：

 

<bean id="propertyConfigurer"  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">     
    <property name="locations">      
         <list>       
           <value>/WEB-INF/jdbc.properties</value>      
        </list>     
    </property>    
</bean> 

 

applicationContext.xml中数据源配置:

<bean id="dataSource"  class="org.springframework.jdbc.datasource.DriverManagerDataSource">   
    <property name="driverClassName">   
        <value>${jdbc.driver}</value>   
    </property>   
    <property name="url">   
        <value>${jdbc.url}</value>   
    </property>   
    <property name="username">   
        <value>${jdbc.user}</value>   
    </property>   
    <property name="password">   
        <value>${jdbc.password}</value>   
    </property>   
</bean>
