Spring中多个工程下多个资源文件ignoreUnresolvablePlaceholders配置

<bean id="propertyConfigurerForAnalysis" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="location">

        <value>classpath:/spring/include/dbQuery.properties</value>

    </property>

</bean>

其中classpath是引用src目录下的文件写法。

当存在多个Properties文件时，配置就需使用locations了：(2)

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="locations">

       <list>

          <value>classpath:/spring/include/jdbc-parms.properties</value>

          <value>classpath:/spring/include/base-config.properties</value>

        </list>

    </property>

</bean>

 接下来我们要使用多个PropertyPlaceholderConfigurer来分散配置，达到整合多工程下的多个分散的Properties 文件，其配置如下：(3)

<bean id="propertyConfigurerForProject1" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="order" value="1" />

    <property name="ignoreUnresolvablePlaceholders" value="true" />

    <property name="location">

       <value>classpath:/spring/include/dbQuery.properties</value>

    </property>
</bean>

 <bean id="propertyConfigurerForProject2" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

    <property name="order" value="2" />

    <property name="ignoreUnresolvablePlaceholders" value="true" />

    <property name="locations">

      <list>

        <value>classpath:/spring/include/jdbc-parms.properties</value>

        <value>classpath:/spring/include/base-config.properties</value>

      </list>

    </property>

</bean>

 

其中order属性代表其加载顺序，而ignoreUnresolvablePlaceholders为是否忽略不可解析的 Placeholder，如配置了多个PropertyPlaceholderConfigurer，则需设置为true

这一个true害了我两天的时间啊）
