1.1. 数据库

1.1.1. 使用navicat创建数据库连接

执行SQL脚本：

1.1.2. Tb_user

查看表结构：

表结构：

eclipse的配置：

1. 修改workspace编码为UTF-8

1.1. 修改jsp编码为UTF-8

2. 修改字体

3. 添加系统中的JDK

4. 导入formatter模板

5. 修改maven配置文件

打开文件：

apache-maven-3.2.3\conf\settings.xml

5.1. 修改本地仓库路径

<localRepository>D:\repository</localRepository>

注意：为了环境统一，建议使用新的本地仓库地址。

5.2. 增加内网镜像服务

使用阿里云的仓库

    <mirror>
         <id>nextus-aliyun</id>
         <mirrorOf>*</mirrorOf>
         <name>Nexus aliyun</name>
         <url>http://maven.aliyun.com/nexus/content/groups/public</url>
   </mirror>

6. 在Eclipse中配置Maven

6.1. 添加本地安装的maven

6.2. 设置setting文件

选择资料包中的maven，并且注意本地仓库地址是否正确。

1.2. 创建工程

1.2.1. 新建工程

1.2.2. 填写项目的Maven坐标

1.3. 统一管理依赖的版本

需要将多个项目的依赖的版本号统一管理起来。

如何实现？  ---  使用Maven的继承实现。

1.3.1. 导入itcast-parent

1.4. 完整pom

1.4.1. 继承parent

1.4.2. 出现小红叉

解决：

原因：

定义的java编译器插件的jdk版本和默认使用的jdk版本不一致，导致。

1.5. 子工程使用依赖

1.5.1. Parent中的依赖管理

1.6. 导入依赖（子工程pom）
