此宠物商城是基于SSM框架，

搭建基于ssm的框架需要以下几步：

一、导入相关jar包，并发布到项目类路径

二、引入相关文件

包括图片文件，css文件，js文件，（所有相关文件以及源码以及SQL文件都以上传点这里）

将这些文件导入到WebRoot文件下：

三、编写配置文件

在src同目录下创建config文件夹（source folder），并在其中创建mybatis的配置文件，spring以及springMVC的配置文件，同时还有一些辅助配置文件，全部创建完成后是下面这样：

四、编写配置文件代码

第三步的时候只是创建了配置文件，但是并没有详细编写，下面一一编写：

jdbc.properties文件：

jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql:///shop
jdbc.username = root
jdbc.password = itcast

log4j.properties文件：

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=c:/mylog.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=DEBUG, stdout

UserValidationMessage.properties文件如下所示：用以储存用户验证信息

#配置校验信息
user.username.length.error=用户名的名字的长度必须是1至30
user.email.notNull=邮箱不可为空

mybatis.xml文件，储存MyBatis相关信息，加载项信息

<?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>
    <settings>
		<setting name="lazyLoadingEnabled" value="true" />
		<setting name="aggressiveLazyLoading" value="false" />
		<setting name="cacheEnabled" value="true"/>
    </settings>
    <!-- 自定义别名 -->
    <typeAliases>
        <package name="com.shop.po"/>
    </typeAliases>
</configuration>

spring的配置文件之一applicationContext-dao.xml文件：（主要用于配置数据源加载mybatis映射文件）

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

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

	</bean>
</beans>

spring配置文件之一applicationContext-service（用于配置service层接口实现类）

spring MVC配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

在web.xml中配置springMvc.xml以及spring的配置文件。并利用过滤器规避乱码问题

<?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_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>SpringMvc_mybatis</display-name>
  <welcome-file-list>
    <welcome-file>index.action</welcome-file>
  </welcome-file-list>
  <!-- springmvc前端控制器 -->
  <servlet>
      <servlet-name>DispatcherServlet</servlet-name>
      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:spring/springMvc.xml</param-value>
      </init-param>
  </servlet>
  <servlet-mapping>
      <servlet-name>DispatcherServlet</servlet-name>
      <url-pattern>*.action</url-pattern>
  </servlet-mapping>
  
  <!-- 加载spring的配置文件 -->
  <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>/WEB-INF/classes/spring/applicationContext-*.xml</param-value>
  </context-param>
  <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!--filter处理post乱码问题  -->
  <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>

五、引入jsp文件

因为我主要想练习后端代码编写，所以直接将所有的jsp文件代码导入到项目中

导入之后如下所示：

六、启动测试

将项目发布到tomcat，启动tomcat，在浏览器网址栏输入http://localhost:8080/TestShop/login.action

结果显示：

这个框架能够正常显示也就代表了此框架已经基本搭建完成，后面几天我再把后台代码再联系一遍。努力吧
