java - Spring 不归档属性文件

Question

我在使用 Spring 访问属性文件时遇到问题。这是我的树状结构:

WEB-INF
   - application-Context.xml
   - properties
      -applicationPerperties.xml
      -csvHeader.properties

这是我在 application-context.xml 中的导入:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"
    profile="dev, test, prod">

    <import resource="properties/applicationProperties.xml" />
</beans>

这是 applicationProperties.xml 中的导入:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="
    http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/util      http://www.springframework.org/schema/util/spring-util-3.0.xsd
    http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <util:properties id="csvDictionnaryProperties"  location="csvHeader.properties" />
</beans>

我不明白的是，Spring 找到了 applicationProperties.xml 但没有找到 csvHeader.Properties。我尝试将此文件移动到根文件夹，添加类路径前缀等，但我无法成功完成这项工作。我总是收到 FileNotFoundException。

这是堆栈跟踪:

正如你所看到的，它似乎在/目录中搜索csvHeader.properties，但我不明白为什么。我是 Spring 的新手，所以我不完全理解这一切。有什么想法为什么这行不通吗？

Answer 1

.properties 文件需要位于 CLASSPATH 中。将其放在项目的 WEB-INF/classes 中，并将其引用为 classpath:csvHeader.properties。 Spring 将会找到它。
