我以前从未使用过spring，甚至没有学过它，在我的工作场所，当我在tomcat中运行应用程序时，我收到以下错误。我不明白，这是什么意思。占位符在$ {}中的值。.应用程序中没有错误，我在日志文件中收到此错误

org.springframework.beans.factory.BeanDefinitionStoreException：名称无效的bean定义“”，在类路径资源[SpringIntegration.xml]中定义：无法解析占位符“”

听起来您正在尝试在 spring 配置中使用外部属性，但没有正确配置的PropertyPlaceholderConfigurerbean。参考本教程：http ://www.mkyong.com/spring/spring-propertyplaceholderconfigurer-example/

在那里，您将找到有关如何声明包含变量配置的属性文件的详细说明，例如：

database.username=myusername
database.password=mypassword
...

然后，您使用以下命令引用该文件PropertyPlaceholderConfigurer：

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location">
        <value>database.properties</value>
    </property>
</bean>

将以下行放入属性文件

VHF.CWS.Hybrid.Contract.RequestQueue=jms://localhost:636
