微信开发准备第二步 springmvc mybatis项目结构搭建

前面一篇有说道如何在myeclipse中搭建maven项目，这里将继续介绍如何在搭建好的基础maven项目中引入我们常用的javaweb框架——springmvc！

①在建立好的maven项目中的pom.xml文件引入依赖，代码如下：

<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
 xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

 </build>
</project>

②修改项目路径下的web.xml文件如下：

<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"
 xmlns:web="http://java.sun.com/xml/ns/javaee" 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

 </jsp-config>
 
</web-app>

③添加数据库配置信息，这里项目配置的数据库为mysql，在 resources下新建config.properties配置文件，设置如下：

validationquery=select 1
jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useunicode=true&characterencoding=utf-8&zerodatetimebehavior=converttonull
jdbc_username=root 
jdbc_password=123456789

④在 resources下新建spring.xml配置文件，设置如下：

<?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:context="http://www.springframework.org/schema/context" xsi:schemalocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
 <!-- 引入属性文件 -->
 <context:property-placeholder location="classpath:config.properties" />
 <!-- 自动扫描(自动注入) -->
 <context:component-scan base-package="com.cuiyongzhi.web.service" />
 <context:component-scan base-package="com.cuiyongzhi.wechat.*" /> 
  
</beans>

⑤在 resources下新建spring-mvc.xml配置文件，设置如下：

<?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc" 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" xsi:schemalocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/mvc 
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
 
 <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->
 <context:component-scan base-package="com.cuiyongzhi.web.controller" />

  </property>
 </bean>

  </property>

  </property>
  <property name="maxinmemorysize">

</beans>

⑥在 resources下新建spring-mybatis.xml配置文件，设置如下：

  <aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />
 </aop:config>
 
</beans>

⑦在 resources下新建log4j.properties配置文件，用于日志的输出等级以及输出位置设置，设置如下：

到这里springmvc+mybatis的基本配置文件基本就完成了，大致的项目结构如下：

本篇主要以代码示例为主，基本的的项目搭建就记录到这里，下一篇我将简述在这个框架下的一些简单应用，感谢你的翻阅，如有疑问可以讨论！
