三、WEB项目开发之SpringMVC+Mybatis搭建网站框架
（一）使用IDEA创建一个新项目
（二）添加整个项目所需的依赖（pom文件）
/* 以下是SpringMVC需要用到的依赖，无需版本号，由“spring-framework-bom”统一管理 */
//为了防止用Maven管理Spring项目时，不同的项目依赖了不同版本的Spring，可以使用Maven BOM来解决者一问题， 即可统一版本，而且，在引入BOM之后，在引入其他Spring依赖时，都无需指定版本
spring-framework-bom ：4.3.17.RELEASE
spring-core
spring-web
spring-webmvc
//这个jar文件是所有应用都要用到的，它包含访问配置文件、创建和管理bean 以及进行Inversion of Control/ Dependency Injection（IoC/DI）操作相关的所有类。
spring-beans
spring-context
//spring表达式语言
spring-expression
//为JDBC、Hibernate、JDO、JPA等提供的一致的声明式和编程式事务管理
spring-tx
spring-jdbc
/* 以上是SpringMVC需要用到的依赖 */
/* Spring配置上传文件解析器需要用到的依赖 */
commons-fileupload
/* 以下是和数据库交互需要用到的依赖 */
mysql-connector-java
//下面两个是Spring中使用Mybatis需要的依赖
mybatis
mybatis-spring
//数据库连接池
druid
/* 以上是和数据库交互需要用到的依赖 */
/* 以下是日志需要用到的依赖 start*/
/*logback-classic中就包含了logback-core、slf4j-apiJAR包。作用就是打印日志提供方法*/
logback-classic
/* logback-ext-spring是Spring提供的，它用于提供listener监听器。 */
logback-ext-spring
/* cl-over-slf4j用来把Spring中大量使用common-logging替换成slf4j。只有有个这个包，才能打印出Spring框架本身的信息数据。*/
jcl-over-slf4j
/* 以上是日志需要用到的依赖 end*/
/* 以下是WEB三贱客 */
javax.servlet-api
jsp-api
jstl
/* 以上是WEB三贱客 */
/* 以下是JSON需要的依赖 */
jackson-core
jackson-annotations
jackson-databind
/* 以上是JSON需要的依赖 */
/* 以下是常用工具需要的依赖 */
commons-lang3
commons-collections4
/* 以上是常用工具需要的依赖 */
/* 以下是测试工具需要的依赖 */
junit
/* 以上是测试工具需要的依赖 */
（四）创建相关配置文件
1、创建与数据库交互需要的属性文件“dao.properties”
#jdbc配置
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/order?autoReconnect\=true&useUnicode\=true&characterEncoding\=utf-8&allowMultiQueries\=true
jdbc.username=root
jdbc.password=root
#druid配置
druid.initialSize=5
druid.maxActive=30
druid.minIdle=1
druid.maxWait=60000
druid.testBetweenEvictionRunMillis=6000
druid.minEvictableIdleTimeMillis=300000
druid.testWhileIdle=true
druid.validationQuery=SELECT 'x'
druid.testOnBorrow=true
druid.testOnReturn=false
druid.poolPreparedStatements=true
druid.maxOpenPreparedStatements=20
druid.filters=wall,stat2、Mybatis核心配置文件（“mybatis.xml”）
<configuration>
<settings>
<setting name="useGeneratedKeys" value="true"/>
<setting name="mapUnderscoreToCamelCase" value="true"/>
settings>
configuration>3、Spring核心配置文件（“applicationContext.xml”）
