SpringMVC-00：整合SpringIOC和SpringMVC_springmvc springioc-优快云博客

本文链接：https://blog.youkuaiyun.com/tianyu00/article/details/89186404

本文详细介绍如何在Eclipse Oxygen环境下，使用JDK1.8、TomcatV8.5和spring-framework-5.0.5搭建SpringMVC项目。涵盖项目结构、配置文件springContext.xml和springmvc.xml的编写，以及web.xml中SpringMVC前端控制器的配置。同时，提供了log4j.properties的日志配置示例。

适合初学者

环境

1.Eclipse Oxygen

2.JDK1.8

3.Tomcat V8.5

4.spring-framework-5.0.5

添加jar包
