1. 简介

1. 功能

思维导图：

1. 架构

   1. 传统架构

存在的问题：

1. 开发、维护代码比较困难
2. 系统内部的功能模块之间的耦合度太高了
3. 无法针对每个模块的特性做优化
4. 无法做服务器的水平扩展
5. 无法存储海量数据

   1. 分布式系统架构

已经解决以上存在的问题，但是，带来了新问题：

1. 系统间的服务的调用变得复杂
2. 如何解决错综复杂的服务调用关系：服务注册中心。

1. 各个系统说明

1. 人员配置

1. 开发流程

1. 现状...

1. 创建taotao-common

创建成功：

1. Pom.xml

1. 创建taotao-manage

   1. 分析

Com.taotao.manage.pojo

Com.taotao.manage.mapper

Com.taotao.manage.service

Com.taotao.manage.controller

使用Maven的聚合将所有的子工程进行创建。

1. 创建taotao-manage

1. Taotao-manage-pojo

1. Taotao-manage-mapper

1. Taotao-manage-service

1. Taotao-manage-web

1. 创建完成

1. 子工程之间的依赖关系

Taotao-manage-web è taotao-manage-service è taotao-manage-mapper è taotao-manage-pojo

1. 导入依赖

导入依赖的原则：

1. 所有的工程都需要的依赖应该在聚合工程（taotao-manage）中导入。
2. 在使用依赖的最底层导入。

3、运行时所需要的依赖在web工程中加入。

1. 导入tomcat插件

聚合工程的tomcat插件要在聚合工程中导入，taotao-manage中导入。

运行tomcat插件：

聚合后运行：

1. 创建web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xmlns="http://java.sun.com/xml/ns/javaee"

    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

    id="WebApp_ID" version="2.5">

    <display-name>taotao-manage</display-name>

    <context-param>

        <param-name>contextConfigLocation</param-name>

        <param-value>classpath:spring/applicationContext*.xml</param-value>

    </context-param>

    <!--Spring的ApplicationContext 载入 -->

    <listener>

        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

    </listener>

    <!-- 编码过滤器，以UTF8编码 -->

    <filter>

        <filter-name>encodingFilter</filter-name>

        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

        <init-param>

            <param-name>encoding</param-name>

            <param-value>UTF8</param-value>

        </init-param>

    </filter>

    <filter-mapping>

        <filter-name>encodingFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- 解决PUT请求无法提交表单数据的问题 -->

    <filter>

        <filter-name>HttpMethodFilter</filter-name>

        <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>HttpMethodFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- 将POST请求转化为DELETE或者是PUT 要用_method指定真正的请求参数 -->

    <filter>

        <filter-name>HiddenHttpMethodFilter</filter-name>

        <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>

    </filter>

    <filter-mapping>

        <filter-name>HiddenHttpMethodFilter</filter-name>

        <url-pattern>/*</url-pattern>

    </filter-mapping>

    <!-- 配置SpringMVC框架入口 -->

    <servlet>

        <servlet-name>taotao-manage</servlet-name>

        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <init-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>classpath:spring/taotao-manage-servlet.xml</param-value>

        </init-param>

        <load-on-startup>1</load-on-startup>

    </servlet>

    <servlet-mapping>

        <servlet-name>taotao-manage</servlet-name>

        <url-pattern>/rest/*</url-pattern>

    </servlet-mapping>

    <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

1. 导入静态页面

1. 配置SSM

1. 通用页面跳转

1. 后台管理系统

   1. 登录页面

登录逻辑：

1. 首页的js布局实现

   1. 布局

左中布局：

1. 左侧菜单树

效果：

1. 菜单的点击事件

1. 选择商品类目

功能描述：在新增商品时点击选择类目，弹出窗口，在窗口中显示商品类目数据。

1. 点击弹出框

1. 加载tree

1. 定义TAOTAO对象

1. 初始化过程

1. 通过TAOTAO.init方法完成初始化
   
2. TT.init中调用initItemCat方法
   
3. 给class=" selectItemCat"绑定click事件，即可实现效果

1. 商品类目的数据结构

创建数据库：

1. 数据

1. 表结构

1. 在taotao-manage-pojo中添加JPA注解依赖

1. EasyUI的tree数据结构

1. 实现

   1. Controller

1. Service

1. ItemCat

import javax.persistence.GeneratedValue;

import javax.persistence.GenerationType;

import javax.persistence.Id;

import javax.persistence.Table;

@Table(name = "tb_item_cat")

public class ItemCat extends BasePojo {

@Id

)

private Long id;

private Long parentId;

private String name;

private Integer status;

private Integer sortOrder;

private Boolean isParent;

public Long getId() {

return id;

}

public void setId(Long id) {

this.id = id;

}

public Long getParentId() {

return parentId;

}

public void setParentId(Long parentId) {

this.parentId = parentId;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public Integer getStatus() {

return status;

}

public void setStatus(Integer status) {

this.status = status;

}

public Integer getSortOrder() {

return sortOrder;

}

public void setSortOrder(Integer sortOrder) {

this.sortOrder = sortOrder;

}

public Boolean getIsParent() {

return isParent;

}

public void setIsParent(Boolean isParent) {

this.isParent = isParent;

}

// 扩展字段，支持EasyUItree的显示

public String getText() {

return this.getName();

}

public String getState() {

return this.getIsParent() ? "closed" : "open";

}

}

1. 效果

1. 提交代码到SVN

   1. 账号

如：张三，zhangsan 密码：123456

地址：svn://192.168.50.22/itcast/36

1. Maven项目提交到SVN

注意：只提交src和pom.xml

1. 提交taotao-parent

1. 忽略不提交的资源

1. 提交完成

1. 从SVN中检出代码

转成Maven项目：

聚合工程的子工程需要导入：
