Question

我想从多个位置加载键值对。我的第一个猜测是：

<util:properties id="requestProcessorRepository"
  location="classpath*:*requestProcessors.properties"/>

但无效

Invocation of init method failed; nested exception is java.io.FileNotFoundException: class path resource [classpath*:*requestProcessors.properties] cannot be opened because it does not exist

没有通配符，它就会起作用。

那么从通配文件创建属性对象/地图的任何其他可能性呢？

Answer 1

首先，您的资源路径classpath*:*requestProcessors.properties不可靠（来自Spring Reference）：

请注意“classpath *：”时结合Ant风格的图案会只能与至少一个人可靠地工作模式之前的根目录启动，除非是实际的目标文件驻留在文件系统中。这意味着像“classpath *：*。xml”这样的模式不会从根检索文件 jar文件，而只是来自扩展目录的根目录。

如果您解决了这个问题，可以按如下方式加载属性：

<bean id = "requestProcessorRepository" 
    class = "org.springframework.beans.factory.config.PropertiesFactoryBean">
    <property name = "locations" 
        value = "classpath*:somefolder/*requestProcessors.properties" />
</bean>

（代码的原始版本更复杂，但没有必要，因为Spring会自动将带有通配符的路径转换为Resource[]。

spring <util：properties> with wildcards </util：properties>
