maven工程建立和SSM（springMVC+spring+mybatis）整合
1.环境：
maven 版本：3.5.1
ecelipse mars.2
JDK : jdk1.8.0_45
tomcat : apache-tomcat-8.0.0-RC1
2. 建maven 工程：
new -> other -> Maven Project-> next-> 勾选 Create a simple project -> next ->
Group Id 填 包名 、Artifact Id 填 工程名、packaging 选 war , 其余5个不填。 -> finish 。
工程上有个小红叉 ,解决方案：
在工程上右键-> javaEE tools -> Generate Deployment Descriptor Stub。
额外配置：工程上右键 -> properties -> Project Facets -> Dynamic Web Module 选3.1 、java 选 1.8 。
3.ssm工程：
model、mapper、conreoller... 代码写在src/main/java 文件夹下。
applicationContext.xml、log4j.properties、
dbconfig.properties、spring-mybatis.xml、spring-servlet.xml放在src/main/resources文件夹下。
在如图选中的位置（src/main/resources）右键 new ->other -> Spring文件下选择Spring Bean Configuration File ->next
->取个名字 -> next -> 选择需要的项，可选择下面对应不同版本。不选版本默认为最新版本。-> finish
这样就可以自动生成文件头，如下图：
4.整合：
applicationContext.xml ：
