Java 在.xml文件中读取.properties文件

类路径中有appcontext.xml文件。我正在使用appcontext.xml中的config.properties文件读取数据库属性。属性文件存储在src/main/config/core/config.properties结构中，我在xml文件中使用它作为

<property name="locations">
   <list>
        <value>${PF_CORE_HOME}/config/core/config.properties</value>
    </list>
</property>

但它会产生错误

org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: class path resource [C:/prov-eng-2/prov-eng/provfwk/pf-core/src/main/config/core/config.properties] cannot be opened because it does not exist

是否有其他方法可以读取.xml中的.property文件。

如果操作正确，这种方法可以工作

这是你的问题：

Caused by: java.io.FileNotFoundException: class path resource [C:/prov-eng-2/prov-eng/provfwk/pf-core/src/main/config/core/config.properties] cannot be opened because it does not exist

您正在从类路径读取此文件，但该路径不是它的一部分

---

在类路径中不包括/src。我会将该.properties文件放在/resources目录中，并将其打包到您的类路径中，例如/classes下的相对路径。

无法加载属性；嵌套异常为java.io.FileNotFoundException:无法打开类路径资源[C:/prov-eng-2/prov-eng/provfwk/pf-core/src/main/config/core/config.properties]，因为它不存在。是否读取了异常？如果文件复制到类路径，则类路径：/core/config.properties。
