IDEA整合SSM框架

第一步：创建 Maven webapp

创建新工程选择maven标签，选择【create from archetype】 选择webapp。

填写GroupID与AritifactId

• GroupId：项目组织唯一的标识符，实际对应 JAVA 的包的结构，也就是 main 目录下 java 的目录结构（包）
• AritifactId：项目的唯一标识符，实际对应项目的名称，就是项目根目录的名称

接下来是确认maven的本地仓库路径还有项目的名称，点击确定即可。

创建好的项目结构如下

第二步：搭建项目目录结构

第三步：配置文件内容

1. web.

<?  version=\"1.0\" encoding=\"UTF-8\"?>
<web-app  ns:xsi=\"http://www.w3.org/2001/ Schema-instance\"  ns=\"http:// ns.jcp.org/ /ns/javaee\" xsi:schemaLocation=\"http:// ns.jcp.org/ /ns/javaee http:// ns.jcp.org/ /ns/javaee/web-app_3_1.xsd\" id=\"WebApp_ID\" version=\"3.1\">
  <display-name>MyBatis_ssm</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>

  <!-- spring 的配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-mybatis. </param-value>
  </context-param>

  <listener>
    <listener-class>org.spring work.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- spring mvc配置 -->
  <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.spring work.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc. </param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>


</web-app>

2. spring 以及 mybatis的配置文件

<?  version=\"1.0\" encoding=\"UTF-8\"?>

</beans>

3. jsbc.properties

jdbc.driver=com.mysql.jdbc.Driver
#数据库地址
jdbc.url=jdbc:mysql://localhost:3306/jumpandjump
##用户名
jdbc.username=root

#当获取连接失败重试次数
c3p0.acquireRetryAttempts=2

4. spring mvc配置文件
