Maven + SSM整合

1开发环境搭建
1.1Eclipse4.7(Oxygen) + Tomcat8 + Maven3.5.2
2Maven Web项目创建
2.1新建maven项目

2.2 选择工作空间

2.3 选择创建web项目

2.4 填写项目相关参数

2.5 完成后的目录结构图

2.6修改为maven约定目录

1、点击项目右键Properties -> Java Build Path ->Source选项

2、点击项目右键new->Source Folder

3、修改index.jsp的错误

在pom.xml添加servlet的支持

4、最终目录结构图

2.7 设置 Properties -> Project Facets

选中3.0 可能会出错

解决方法：修改该项目路径下的 .settings/ org.eclipse.wst.common.project.facet.core.xml 文件

关闭项目再重新打开

3SSM整合
3.1Spring和Mybatis的整合
3.1.1Maven引入需要的Jar包

1、本教程使用部分jar的版本：
       Spring: 5.0.2.RELEASE
       Spring MVC: 5.0.2.RELEASE
       MyBatis:  3.4.5
       mybatis-spring:  1.3.0
       mysql-connector-java: 5.1.2
       javax.servlet-api：3.1.0 
       commons-dbcp: 1.4
       commons-io:  2.5
       commons-codec: 1.10
2、pom.xml
<properties>  
       <!-- spring版本号 -->  
       <spring.version>5.0.2.RELEASE</spring.version>  
       <!-- mybatis版本号 -->

       <!-- log4j日志文件管理包版本 -->

3.1.2 建立JDBC属性文件（文件编码修改为utf-8）：

jdbc.driver_class=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///ssm
jdbc.username=root
jdbc.password=root
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

3.1.3 建立spring-mybatis.xml配置文件

3.1.4JUnit测试Mybatis
3.1.4.1创建测试用表

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (
  `id` INT(11) NOT NULL AUTO_INCREMENT,
  `username` VARCHAR(40) NOT NULL,
  `password` VAR以上是关于Maven+SSM整合.doc的主要内容，如果未能解决你的问题，请参考以下文章
