Question

我在类路径中有appcontext.xml文件。我在appcontext.xml中使用config.properties文件来读取数据库属性。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，

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

但它会出错，

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

还有其他方法可以在.xml中读取.property文件。

如果你正确地这样做，这种方式就有效。

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CLASSPATH读取此文件，但该路径不是它的一部分。

您的CLASSPATH中不包含/ src。我将.properties文件放在/ resources目录中并将其打包到CLASSPATH中（例如/ classes下的相对路径）。

在.xml文件中读取.properties文件
