Eclipse的Web Maven项目创建和配置

1.Maven项目的创建(版本我的是JDK:1.8,TomCat8.0)
打开eclipse右键选择new–>project–>Maven Project,然后next到
选择红线圈中的这个点nextEclipse的Web Maven项目创建和配置-LMLPHP
接着填入Group Id和Artifact Id 点击Finish。完成项目的创建

创建完成后可能会报错,那是Tomcat未引入,右键项目点击properties,选择java Build Pach,在Libraries中点击Add Libraries,选择Server Runtime,选择Tomcat版本点击Finish即可。

这里面的Map工具类和wechat相关个人需要可以不加。pom.xml要引入的最核心的配置文件是,单元测试,日志,数据库,MyBatis,Servlet web ,json解析 ,Spring的核心包,spring web,spring Dao,spring test。如果想自己练习配置可以到 https://mvnrepository.com/ 中寻找需要的配置文件。

3.数据库的配置
jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/o2o?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

mybatis-config.xml的配置

<?xml version="1.0" encoding="UTF-8" ?>
 <!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 配置全局属性 -->
	<settings>
		<!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 -->
		<setting name="useGeneratedKeys" value="true" />

		<!-- 使用列别名替换列名 默认:true -->
		<setting name="useColumnLabel" value="true" />
 
		<!-- 开启驼峰命名转换:Table{create_time} -> Entity{createTime} -->
		<setting name="mapUnderscoreToCamelCase" value="true" />
		<!-- 打印查询语句 -->
		<setting name="logImpl" value="STDOUT_LOGGING" />

这样一个Maven项目就配置好了可以进行web开发啦。
