#### 一、 前期准备 ####

安装必要的开发环境

> eclipse/intellij+maven 3.5.x + tomcat 7/8/9+mysql 5.x

将sql目录下面的5个SQL文件导入数据库中

#### 二、 程序实现 ####

##### 1. 项目结构 #####

![web页面代码结构][web]

##### 2. 主要配置 #####

1.  流程引擎的配置

在activiti.cfg.xml和spring-mybatis.xml配置文件中，主要配置了流程引擎，数据源(用于流程引擎自动生成与之相关的数据表)

<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
            <property name="dataSource" ref="dataSource"/>
            <property name="transactionManager" ref="transactionManager"/>
            <property name="databaseSchemaUpdate" value="true"/>
        </bean>
    
        <bean id="dbProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
            <property name="location" value="classpath:jdbc.properties"/>
            <property name="ignoreUnresolvablePlaceholders" value="true"/>
        </bean>
    
         <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${jdbc.driver}"/>
            <property name="url" value="${jdbc.url}"/>
            <property name="username" value="${jdbc.username}"/>
            <property name="password" value="${jdbc.password}"/>
            <property name="defaultAutoCommit" value="false"/>
        </bean>
    
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"/>
        </bean>

##### 2. spring与mybatis的整合 #####

<context:property-placeholder location="classpath:jdbc.properties" ignore-unresolvable="true" />
    
        
        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
            <property name="driverClassName" value="${jdbc.driver}" />
            <property name="url" value="${jdbc.url}" />
            <property name="username" value="${jdbc.username}" />
            <property name="password" value="${jdbc.password}" />
        </bean>
    
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            
            <property name="mapperLocations" value="classpath:com/activiti/mapping/*.xml"></property>
        </bean>
    
        
        <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="basePackage" value="com.activiti.dao" /> 
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
        </bean>

##### 3. Spring与SpringMVC整合 #####

将SpringMVC整合进来，方便将前端结合起来

##### 4. java和页面实现 #####

这份代码就不每个都粘贴了，是包含了相关页面的和后台代码的，具体的运行效果，看以下部分。

#### 三、运行效果 ####
