maven+SSM框架工程搭建

来源：互联网发布：知名品牌网络授权编辑：程序博客网时间：2024/06/05 23:03

1.百度下载 maven 和 tomcat 安装配置环境变量

2.使用最新版eclipse 集成maven

maven conf文件夹下的settings.xml文件配置存放maven仓库的位置，D:\hongzhimei\repository 为存放路径

3.新建工程

项目原型选择webapp项目

在buildPath中选择Edit更改为工作空间默认的jdk，项目目录会变成这样

在程序部署中把test删除，程序就不会编译test的代码

在pom.xml文件中添加依赖,然后等待jar包下载.

 pom.xml

目前这里会有个报错，需要配置一下servlet，我这里用的是Tomcat6

这样就不报错了。

4.数据库搭建

我这里就用了mysql，插入了一张很简单的表。

5.整合SSM框架

搭建目录

在resource文件夹下加上这些配置文件

6.运行测试

显示结果

下面是jsp java代码
