从今天开始，我们将进入猿实战的阶段，实现一个前后端分离的电商系统，没有开发框架怎么行？今天是第一个系列，猿人君将带你搭建后端开发框架。
创建应用父模块
父模块负责控制整个应用的结构,因为pzmall-basic作为父项目的存在，无需编写代码,记得在创建完成后，删除项目下的src目录。
创建子模块
考虑到我们需要构建一个B2C(兼容商家端的应用)我们的应用按照代码职责的划分，我们的应用暂时涉及到一下几个模块。
pzmall-basic-common:负责编写项目公用的一些内容，比如工具类。
pzmall-basic-domain:负责项目涉及的实体内容编写。
pzmall-basic-dao:负责数据持久层的内容编写。
pzmall-basic-service：负责业务逻辑层的内容编写。
pzmall-basic-search-util：负责项目搜索引擎工具相关的内容编写。
pzmall-basic-web:负责项目网站端业务内容编写。
pzmall-basic-manweb:负责项目运营管理端业务内容编写。
接下来我们一起来创建子项目pzmall-basic-common。
接下来，以葫芦画瓢，建立pzmall-basic-domain、pzmall-basic-dao、pzmall-basic-service、pzmall-basic-search-util几个子模块，最后得到如下结果。
由于pzmall-basic-web和pzmall-basic-manweb属于web应用，在创建时有所区别，在选择maven项目类型时记得选择正确的archetype,org.apache.maven.archetypes:maven-archetype-webapp.
完成后，并在模块的src/main目录下建立java和resources两个目录。
最后项目的整体结果效果如下，为了测试下效果，编译下项目。
调整项目依赖
就项目模块之间的依赖关系而言，pzmall-basic-common和pzmall-basic-serch-util由于编写的是工具类，相对独立，不依赖于其它模块。pzmall-basic-domain、pzmall-basic-dao、pzmall-basic-service、三者的依赖是存在关联关系的，pzmall-basic-service依赖pzmall-basic-dao，pzmall-basic-dao依赖pzmall-basic-domain。而之前提及的pzmall-basic-common和 pzmall-basic-serch-util更多的会在service层被使用。所以，pzmall-basic-service会依赖pzmall-basic-common和pzmall-basic-serch-util。注意哈，pzmall-basic-domain要尽量保持干净，不要和工具类扯上什么关系，否则对今后的架构方面的扩展，是不友好的。而pzmall-basic-web和pzmall-basic-manweb作为项目最终要部署的war包，依赖pzmall-basic-service就可以了。
接下来我们调整引入各个层面所需要的依赖，搭建我们项目开发所需要的框架。
修改父项目pzmall-basic下pom.xml内容为：

搭建开发框架
1.在pzmall-basic-dao模块的src/main目录下建立resources/mybatis目录,并在mybaits目录下建立SqlMapConfig.xml文件以及mapper目录。
SqlMapConfig.xml下用于配置mybatis全局相关的一些属性，以及加载哪些mapper配置文件，mapper目录下未来将按模块存放相干的mapper文件。
2.在pzmall-basic-manweb目录的resources目录下分别建立spring和config两个目录。并在resources目录下建立applicationContext.xml文件。如下图所示。
3.整合mybatis，在spring目录中建立文件，spring-dao.xml并输入如下内容。
<?xmlversion="1.0" encoding="UTF-8"?>

<property name="sqlSessionFactoryBeanName"value="mybatisSqlSessionFactory"/>
<propertyname="basePackage" value="com.pz.basic.mall.dao" />
</bean>
</beans>
4.配置事务相关的内容，在spring目录中建立文件，spring-tx.xml并输入如下内容。
<?xmlversion="1.0" encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"> <!-- 事务管理器 -->
<bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<propertyname="dataSource" ref="dataSource" />
</bean> <!-- 开启事务控制的注解支持 -->
<tx:annotation-driventransaction-manager="transactionManager"/> </beans>
5.配置SpringMVC相关内容，先在spring目录中建立文件spring-service.xml备用，然后再建立一个springmvc.xml文件，并在文件中输入如下内容。
<?xmlversion="1.0" encoding="UTF-8"?>
<beansxmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:p="http://www.springframework.org/schema/p"

6.由于我们打算使用前后端分离的方式来开发项目，需要解决跨域问题，我们使用了拦截器的方式来处理这个问题，也在springMVC中做了相应的配置。在pzmall-basic-manweb模块中编写代码。
package com.pz.basic.mall.interceptor; import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List; /**
* 处理跨域请求
*/
public classCommonInterceptor implements HandlerInterceptor { private List<String> excludedUrls; public List<String> getExcludedUrls(){
return excludedUrls;
} public voidsetExcludedUrls(List<String> excludedUrls) {
this.excludedUrls = excludedUrls;
} /**
*
* 在业务处理器处理请求之前被调用如果返回false
* 从当前的拦截器往回执行所有拦截器的afterCompletion(),
* 再退出拦截器链, 如果返回true 执行下一个拦截器,
* 直到所有的拦截器都执行完毕再执行被拦截的Controller
* 然后进入拦截器链,
* 从最后一个拦截器往回执行所有的postHandle()
* 接着再从最后一个拦截器往回执行所有的afterCompletion()
*
* @param request
*
* @param response
*/
public boolean preHandle(HttpServletRequestrequest, HttpServletResponse response,
Object handler)throws Exception { response.setHeader("Access-Control-Allow-Origin","*");
response.setHeader("Access-Control-Allow-Methods", "POST,GET, PUT, OPTIONS, DELETE, PATCH");
response.setHeader("Access-Control-Max-Age","3600");
response.setHeader("Access-Control-Allow-Headers","X-Token, Origin, X-Requested-With, Content-Type, Accept");
response.setHeader("Access-Control-Allow-Credentials","true");
response.setHeader("XDomainRequestAllowed","1");
return true;
} // 在业务处理器处理请求执行完成后,生成视图之前执行的动作
public void postHandle(HttpServletRequestrequest, HttpServletResponse response, Object handler,
ModelAndViewmodelAndView) throws Exception { } /**
*
* 在DispatcherServlet完全处理完请求后被调用
* 当有拦截器抛出异常时,
* 会从当前拦截器往回执行所有的拦截器的afterCompletion()
*
* @param request
*
* @param response
*
* @param handler
*
*/
public voidafterCompletion(HttpServletRequest request, HttpServletResponse response,
Object handler,Exception ex) throws Exception { }
}
7.修改pzmall-basic-manweb模块中的resources/config目录下增加db.properties文件，加入数据库相关的配置。
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/pz_mall_basic?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456
8.在resources目录下新增log4j.properties文件，增加日志相关配置。
log4j.rootLogger=trace,console
logging.level.com.pz.mall.dao=DEBUG
log4j.appender.console= org.apache.log4j.ConsoleAppender
log4j.appender.console.Target= System.out
log4j.appender.console.layout= org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=[%-5p][%d{yyyy-MM-dd HH:mm:ss}]%m%n log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.Java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
9.修改pzmall-basic-manweb模块中的web.xml文件，增加应用启动相关配置：
<?xmlversion="1.0" encoding="UTF-8"?>
<web-appxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">
<!-- 解决post乱码 -->
<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>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> <servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 指定加载的配置文件，通过参数contextConfigLocation加载 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet> <servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param> </web-app>
到此为止，我们项目的开发框架搭建完毕。
