SSM框架整合(以淘淘商城为例)

1.1. 后台系统所用的技术

框架:Spring + SpringMVC + Mybatis

前端:EasyUI

数据库:mysql

1.2. 创建数据库

1、安装mysql数据库

2、在mysql中创建一个taotao数据库

3、导入数据库脚本。

 

1.3. Mybatis逆向工程

执行逆向工程

使用官方网站的mapper自动生成工具mybatis-generator-core-1.3.2来生成po类和mapper映射文件。

 

 

1.4. 整合思路

1、Dao层:

mybatis整合spring通过spring管理SqlSessionFactorymapper代理对象。需要mybatisspring的整合包。

整合内容

对应工程

Pojo

Taotao-mangaer-pojo

Mapper映射文件

Taotao-mangaer-mapper

Mapper接口

Taotao-mangaer-mapper

sqlmapConfig.xml

Taotao-manager-web

applicationContext-dao.xml

Taotao-manager-web

 

2、Service层:

所有的实现类都放到spring容器中管理。由spring创建数据库连接池,并有spring管理实务。

整合内容

对应工程

Service接口及实现类

Taotao-mangaer-service

applicationContext-service.xml

Taotao-manager-web

applicationContext-trans.xml

Taotao-manager-web

 

3、表现层:

Springmvc整合spring框架,由springmvc管理controller

整合内容

对应工程

springmvc.xml

Taotao-manager-web

Controller

Taotao-manager-web

 

1.5. Dao整合

1.5.1. 创建SqlMapConfig.xml配置文件

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>

 

configuration>

 

1.5.2. Spring整合mybatis

创建applicationContext-dao.xml

备注:

Druid是目前最好的数据库连接池,在功能、性能、扩展性方面,都超过其他数据库连接池,包括DBCPC3P0BoneCPProxoolJBoss DataSource

Druid已经在阿里巴巴部署了超过600个应用,经过多年多生产环境大规模部署的严苛考验。

1.7.3. 整合静态页面

静态页面位置:02.第二天(三大框架整合,后台系统搭建)\01.参考资料\后台管理系统静态页面

 

使用方法:

把静态页面添加到taotao-manager-web工程中的WEB-INF下:

 

由于在web.xml中定义的url拦截形式为“/”表示拦截所有的url请求,包括静态资源例如cssjs等。所以需要在springmvc.xml中添加资源映射标签:

<mvc:resources location="/WEB-INF/js/" mapping="/js/**"/>

<mvc:resources location="/WEB-INF/css/" mapping="/css/**"/>

 

 

1.8. 修改taotao-manager-mapperpom文件

pom文件中添加如下内容:

<build>

<resources>

            <resource>

                <directory>src/main/javadirectory>

                <includes>

                    <include>**/*.propertiesinclude>

                    <include>**/*.xmlinclude>

                includes>

                <filtering>falsefiltering>

            resource>

        resources>

build>

1.9. 整合测试

根据商品id查询商品信息。
