### PropertyPlaceHolderConfigurer 和 ProperiesFactoryBean ###

#### 目前使用方式 ####

在Application-context.xml 配置

PropertyPlaceHolderConfigurer

<bean id="propertyConfigurer"
              class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="locations">
                <list>
                    <value>classpath:system.properties</value>
                    <value>classpath:facemask.properties</value>
                    <value>classpath:ximalaya-xdcs.properties</value>
                </list>
            </property>
        </bean>
    
     <!-- 使用 -- >
        <mainstay:client id="facemask-vip-client"
                         group="business-vip"
                         application="facemask-server"
                         protocol="protocol"
                         registry="registry"
                         iface-class="com.ximalaya.business.vip.query.thrift.api.ThriftVipQueryService.Iface"
                         timeout="${facemask.client.timeout}"
                         filter="circuitBreakerClient"/>

PropertiesFactoryBean

<bean id="setting"  
            class="org.springframework.beans.factory.config.PropertiesFactoryBean">  
            <property name="locations">  
                <list>  
                    <value>classpath:thrift.properties</value>  
                </list>  
            </property>  
              
            <property name="fileEncoding" value="UTF-8"></property>  
        </bean>  
    
    
       
       <mainstay:registry id="registry" address="#{thrift['zookeeper.connect.url']}" legacy="true"></mainstay:registry>
        <mainstay:protocol id="protocol" codec="thrift"></mainstay:protocol>

### @Value的使用 ###

$\{property:default\_value\}  
\#\{obj.property?:default\_value\}

\#\{ SpEL \}

### football-client 的实现方式 ###

1.  继承PropertyPlaceHolderConfigurer, 重写 loadProperties方法，将properties从local文件读取，调用ConfigService。从配置中心读取。即可。
2.  继承PropertiesFactoryBean，重写 loadProperties方法，道理一致。
