环境总体目标
创建工程
项目结构图
工程创建计划
只有web是war包
reverse是逆向工程
util是工具模块
建立工程的依赖关系
看项目结构图完成项目依赖
创建数据库和数据库表
1、物理建模
1、第一范式:原子性,每一column独立不可再分
2、第二范式:所有非主键字段完全依赖主键字段
3、第三范式:所有非主键字段不完全依赖非主键字段
2、创建数据库

Spring整合Mybatis(配置+注解)
目标
adminMapper通过IOC容器装配到当前组建后,就可以直接调用,方便快捷.
@Service public class AdminServiceImpl implements AdminService { @Autowired private AdminMapper adminMapper; public Admin getAdminById(Integer adminId){ return adminMapper.selectByPrimaryKey(adminId); } }
思路
配置步骤
- 在子工程(admin-web)导入需要的依赖
- 配置spring整合mybatis
- 准备jdbc.properties
- 创建spring.xml
- 配置数据源
- 配置SqlSessionFactoryBean
- 装配数据源
- 指定xxxMapper.xml配置文件的位置
- 指定Mybatis全局配置文件
- 配置MapperScannerConfiguter
- 测试

小结
日志系统
声明式事务
表述层工作机制
访问过程
表述层环境搭建
导入依赖
使用springmvc环境引入spring-mvc依赖即可
web.xml配置
1、contextLoaderListener
作用:加载spring的配置文件,根据Spring的配置文件初始化IOC容器
2、characterEncodingFilter
解决post请求的字符乱码问题
3、HiddenHttpMethodFilter
遵循restful风格将post请求转换为put请求、delete请求使用
4、DispatcherSerlet
前端控制器
代码

请求扩展名
让请求扩展名和预计的响应体数据格式一致
Springmvc.xml配置

页面上的base标签
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>Title</title> <base href="http://${pageContext.request.serverName }:${pageContext.request.serverPort }${pageContext.request.contextPath }/> </head> <body> </body> </html>
springmvc环境下的ajax请求
前端页面
静态资源引入
由于SpringMVC会默认拦截所有请求,因此需要在SpringMVC配置资源不拦截或者在web.xml配置如下:
<servlet-mapping> <servlet-name>springDispatcherServlet</servlet-name> <!-- DispatcherServlet 映射的 URL 地址 --> <!-- 大白话:什么样的访问地址会交给 SpringMVC 来处理 --> <!-- 配置方式一:符合 RESTFUL 风格使用“/” --> <!-- <url-pattern>/</url-pattern> --> <!-- 配置方式二:请求扩展名 --> <url-pattern>*.html</url-pattern> <url-pattern>*.json</url-pattern> </servlet-mapping>
初步显示管理员登陆页面
配置view-controller,这样就能够直接跳转到某个页面.
<mvc:view-controller path="/admin/to/login/page.html" view-name="admin-login"/>
异常映射
以常量管理属性名和异常消息
作用:以防打字错误
