3. 创建项目(检测是否配置成功，这里创建的是web项目)

如何在java项目中应用SSM框架

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。
