1.導包。
2.配置web.xml.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>SSMenvironment2</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-list>
<!-- 載入spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- springmvc前端控制器 -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- contextConfigLocation配置springmvc載入的配置檔案(配置處理器對映器、介面卡等等) 如果不配置contextConfigLocation,預設載入的是/WEB-INF/servlet名稱-serlvet.xml(springmvc-servlet.xml) -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<!-- 第一種:*.do,訪問以.do結尾 由DispatcherServlet進行解析
第二種:/,所以訪問的地址都由DispatcherServlet進行解析,對於靜態檔案的解析需要配置不讓DispatcherServlet進行解析
使用此種方式可以實現 RESTful風格的url
第三種:/*,這樣配置不對,使用這種配置,最終要轉發到一個jsp頁面時, 仍然會由DispatcherServlet解析jsp地址,不能根據jsp頁面找到handler,會報錯。 -->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- post亂碼過慮器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
3.在src下建立包。
說明:bean包放javabean類,exception包自定義exception類,interceptor包放攔截器類(如果需要的話),mapper包放XxxMapper.java類和XxxMapper.xml配置檔案(記住這兩個檔案的名字一定要相同),service包放Service類,web包放Controller類,test包放test類(若需要的話),config包放spring和mybatis的配置檔案。
4.config中配置檔案的編寫。
config包中的結構(不一定非要一樣)。
sqlMapConfig.xml(mybatis的配置檔案)。
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 全域性setting配置,根據需要新增 -->
<!-- 全域性配置引數,需要時再設定 -->

<!-- 將積極載入改為消極載入即按需要載入 -->
<setting name="aggressiveLazyLoading" value="false"/>
<!-- 開啟二級快取 -->
<setting name="cacheEnabled" value="true"/>
</settings>
<!-- 配置別名 -->
<typeAliases>
<!-- 批量掃描別名 -->
<package name="com.tyust.bean"/>
</typeAliases>
<!-- 配置mapper
由於使用spring和mybatis的整合包進行mapper掃描,這裡不需要配置了。
必須遵循:mapper.xml和mapper.java檔案同名且在一個目錄
-->
<!-- <mappers>
</mappers> -->

5.測試mybatis連線資料庫是否成功。
6.開發。
