maven+springMVC+mybatis+junit详细搭建过程

摘要  在做javaweb的过程中，搭建框架式比较头疼事情了，每次重新去搭建太浪费时间了，现在把框架搭建完成，可以在以后的项目中运用，节约开发成本。

springMVC+mybatis框架搭建

在上一遍博客中以及讲诉了新建maven项目的流程，现在紧跟上一遍文章，接着搭建spring项目

首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？

（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）

1.  工程目录结构整理清楚

在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean),

                                            cn.springmvc.dao（存放spring与mybatis连接接口）,

                                            cn.springmvc.service（service接口）,

                                            cn.springmvc.service.impl（service接口的实现），

                                            cn.springmvc.controller（存放控制层controller）

在src/main/resource文件夹中，新建包conf（存放配置文件），

                                                   mapper（mybatis的mapper文件）

在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）

这样项目结构基本完成了

2.  引入依赖包

打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）

查找依赖结构有个不错的网站，http://search.maven.org/   只要输入包名即可查找引来关系

pom.xml(包依赖)

3. 配置数据库连接属性

conf/ jdbc.properties（jdbc配置文件)

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql: //localhost:3306/mydays?useUnicode=true&characterEncoding=utf-8
jdbc_username=root
jdbc_password=root

4.  配置spring配置文件

    conf/spring.xml(spring配置文件的扫描)

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


    < context:property-placeholder location = "classpath:conf/jdbc.properties" />


    < context:component-scan base-package = "cn.springmvc.service" />
beans >

  conf/spring-mybatis.xml（spring与mybatis连接属性）

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