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-3.2.3confsettings.xml
5.1. 修改本地仓库路径
<localRepository>D: epository</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）

1.7. 运行tomcat插件
运行出错：
问题：
解决：
需要将itcast-parent安装到本地仓库。
