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

<scripting-invalid>false</scripting-invalid> <include-prelude>/WEB-INF/common/head.jsp</include-prelude> </jsp-property-group> </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=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"

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php中文网其它相关文章！ |
