我正在向现有的Java EE项目添加新功能,该项目涉及三个层:数据、业务和表示。使用了Spring2.5和JDK 1.4.2。
业务层(域对象项目)使用Spring管理jdbc事务,并照常注入DAO和服务。它有" Spring -config.xml“来配置Spring。它工作得很好。
表示层将使用Spring2.5、纯JSP和Tomcat 5.0。然而,我被困在设置web.xml以在项目启动时加载Spring。
web.xml如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

</web-app>Tomcat 5的错误堆栈跟踪如下所示:
SEVERE: Context initialization failed
org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition. Group resource name [classpath:Spring-config.xml], factory key [businessBeanFactory]; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [Spring-config.xml]; nested exception is java.io.FileNotFoundException: class path resource [Spring-config.xml] cannot be opened because it does not exist

at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:186)
at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:45)它显然会抱怨找不到"Spring-config.xml“;但是域项目已经被设置为web项目的依赖项。
我是Spring的新手,但是有人能给我一些建议吗?谢谢
关于配置像这样的3层Spring项目,有什么最佳实践吗?

Spring-config-xml必须在根类路径上。您没有解释这个文件的位置以及如何在Tomcat中部署您的应用程序。
