微信开发之springmvc mybatis项目结构搭建的java代码详解

这篇文章主要为大家详细介绍了微信开发准备第二步，springmvc和mybatis项目结构的搭建，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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

</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 1jdbc_url=jdbc:mysql://127.0.0.1:3306/wechat?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=root jdbc_password=123456789④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/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://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/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd 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" /><!-- 避免IE执行AJAX时,返回JSON出现下载文件 --> <bean id="mappingJacksonHttpMessageConverter">⑥在 resources下新建spring-mybatis.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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><!-- 配置数据源 --> <bean name="dataSource">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！以上就是微信开发之springmvc mybatis项目结构搭建的java代码详解的详细内容，更多请关注小潘博客其它相关文章！
