Spring中多个工程下多个资源文件ignoreUnresolvablePlaceholders配置
<bean id="propertyConfigurerForAnalysis" value="1" />
<property name="ignoreUnresolvablePlaceholders" value="true" />
<property name="location">
<value>classpath:/spring/include/dbQuery.properties</value>
</property>
</bean>
?
<bean id="propertyConfigurerForProject2" 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)

至此你已经了解到了如何使用PropertyPlaceholderConfigurer,如何使用多个Properties文件,以及如何配置多 个PropertyPlaceholderConfigurer来分解工程中分散的Properties文件。至于 PropertyPlaceholderConfigurer还有更多的扩展应用,如属性文件加密解密等方法将在之后的博文中续写。
