本篇文章给大家分享的是有关如何在java项目中应用SSM框架，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。
配置环境变量
配置完后，使用命令行输入mvn -version查看是否配置成功，出现以下界面表示配置成功。
在MyEclipse中配置maven
打开MyEclipse2015————点击菜单栏Window———选项栏Preference ，搜索Maven,进入Installations,点击Add引入安装的maven。
进入User Setting,设置Global Setting,选中安装的maven的settings.xml配置文件（以上步骤已经完成maven配置）
创建项目(检测是否配置成功，这里创建的是web项目)
点击项目右键->Run as->Maven install将依赖install至本地maven库，有可能会报：
-Dmaven.multiModuleProjectDirectorysystem propery is not set. Check $M2_HOME environment variable and mvn scriptmatch.，
表示JDK版本和maven有冲突，更改一下jdk版本，并且加上-Dmaven.multiModuleProjectDirectory=$M2_HOME即可；
如运行过程中控制台如下图所示,表示成功。
在maven项目中搭建spring+springMVC+MyBatis
修改pom.xml添加对应的包依赖
