java - Maven项目: Spring cannot find property file inside src/main/resources using PropertyPlaceholderConfigurer

Question

Spring 在 src/main/resources 中找不到我的属性文件 (MyPropFile.properties) 并抛出如下异常

java.io.FileNotFoundException: class path resource [file*:/src/main/resources/MyPropFile.properties] cannot be opened because it does not exist

但是如果我将 MyPropFile.properties 放在项目的根目录 (MyProject/MyPropFile.properties) spring 可以找到它并且程序可以正确执行。

如何配置它以便我可以将 .properties 文件放入 src/main/resources

这是我的命名空间

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/aop 
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd 
    http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-3.0.xsd
    ">

这是我的 bean

<context:property-placeholder location="classpath:MyPropFile.properties" />

Java:

@Value("${message.fromfile}")
      private String message;

提前谢谢大家。

试试这个。在您的应用程序配置文件中添加此条目:

<beans xmlns:context="http://www.springframework.org/schema/context"
 .....
 xsi:schemaLocation="...
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-3.0.xsd
 ....>

<context:property-placeholder location="classpath:MyPropFile.properties" />
 ....
</beans>

并访问消息属性:

@Value("${messageFromfile}")
private String message;
