我正在尝试构建一个独立的基于Spring的Java应用程序。
我正在使用Maven程序集插件来构建具有依赖关系的JAR。 JAR的结构最终看起来像这样(只是一个子集):
com
META-INF
org
properties
- taskexecutor.properties
spring
- properties.xml
.
.
.
清单看起来像这样:
Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: authorname
Build-Jdk: 1.6.0_30
Main-Class: com.company.utilities.task.TaskLauncher
当应用程序运行时,应通过包含properties.xml文件来配置属性占位符:
<?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"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:property-placeholder location="classpath:/properties/taskExecutor.properties"/>
</beans>
它在Eclipse中运行良好,但是当我运行JAR时,出现此错误:
Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileN
otFoundException: class path resource [properties/taskExecutor.properties] cannot be opened because it does not exist

... 6 more
有任何想法吗?
将taskExecutor.properties移至root并尝试
<context:property-placeholder location="taskExecutor.properties"/>
似乎通过命令行运行时区分大小写,但是在加载这些资源时Eclipse并不区分大小写。
将taskexecutor.properties
重命名为taskExecutor.properties
解决此问题。 哎呀。 希望这对以后和我一样愚蠢的人有所帮助;-)
