创建名称为 bean 时出错：自动装配依赖项注入失败，无法解析占位符

Question

我正在尝试在 tomcat 服务器上运行我的应用程序（spring + hibernate），但出现这些错误。当我评论导致错误的属性时，下一个属性会触发相同的错误。我猜想在初始化期间无法识别这些属性，我尝试了很多解决方案，但没有一个解决问题。有谁有办法解决这个问题吗？

通过在pom中添加这一行解决了这个问题

<filtering>true</filtering>

给予这个

<build>
    <resources>     
        <resource>
            <filtering>true</filtering>
            <directory>src/main/resources</directory>
            <includes>                      
                <include>**/*.properties</include>                  
            </includes>
        </resource>
