Java初级项目学习第二讲：Eclipse+Maven+SSM搭建项目

Eclipse+Maven+SSM搭建项目

使用eclipse搭建maven项目，搭配SSM框架整合。

一、准备资源

JDK：JDK1.8
Maven：Maven3.8.5
Tomcat：Tomcat8.5

二、架构准备

打开Eclipse，选择window–>preferences，配置JDK
选择window–>preferences，配置Maven
选择window–>preferences，配置Tomcat

三、项目部署

打开Eclipse，File–>new–>other–>maven–>Maven project
group Id:你的项目组（域名）
Artifact Id：项目名称

项目创建完成后，在项目上右键–>properties
将JDK和Tomcat支持加入项目中
将项目设置的Java设置为1.8，将Dynamic Web Module设置为3.1

四、配置文件

项目结构
注：项目报红叉是因为XML格式问题，项目可以正常运行
