条件：

a)    Activiti5.4版本;

        b)    Eclipse开发工具;

        c)    MySQL 5.0以上版本;

         1，使用Eclipse创建一个Web工程；(注： a，在创建Web 工程之前，要先配置tomcat 的目录；b，在创建Web工程之后，改变编译后的class 文件和资源文件的存放位置； c，指定编码格式，UTF-8)

2，导入相应的 jar 包；（注： jar 包分为 SSH框架所需要的jar包和Activiti 5.4的 jar 包）

            http://download.csdn.net/detail/samile6899/9631620   ( SSH所需JAR包 )

            http://download.csdn.net/detail/samile6899/9631623  （ Activiti 所需JAR包 ）

3，配置文件

                

               以下分别是各个配置文件：

                

                     activiti-context.xml文件：

               新建com.itcast.ssh.domain 包，在domain 包中新建 hibernate 需要的 javabean和映射文件(  xxxx.hbm.xml  )

                      Employee类：

package cn.itcast.ssh.domain;

public class Employee {
	private Long id;
	private String name;
	private String password;
	private String email;
	private String role;
	private Employee manager;
	
	public Employee() {
		super();
	}

	public Employee(Long id, String name, String password, String email, String role, Employee manager) {
		super();
		this.id = id;
		this.name = name;
		this.password = password;
		this.email = email;
		this.role = role;
		this.manager = manager;
	}

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getRole() {
		return role;
	}

	public void setRole(String role) {
		this.role = role;
	}

	public Employee getManager() {
		return manager;
	}

	public void setManager(Employee manager) {
		this.manager = manager;
	}
	
}

Employee.hbm.xml 文件：              

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</id>
<property name="name" type="string" column="name" unique="true" />

<property name="role" type="string" column="role" />
       <many-to-one name="manager" class="Employee" column="manager_id"></many-to-one>
</class>
</hibernate-mapping>

               LeaveBill类：

package cn.itcast.ssh.domain;

import java.util.Date;

public class LeaveBill {
	private Long id;
	private Integer days;
	private String content;
	private Date leaveDate=new Date();
	private String remark;
	private Employee user;
	private Integer state=0;
	
	public LeaveBill() {
		super();
	}

	public LeaveBill(Long id, Integer days, String content, Date leaveDate, String remark, Employee user,
			Integer state) {
		super();
		this.id = id;
		this.days = days;
		this.content = content;
		this.leaveDate = leaveDate;
		this.remark = remark;
		this.user = user;
		this.state = state;
	}

	public Long getId() {
		return id;
	}

	public void setId(Long id) {
		this.id = id;
	}

	public Integer getDays() {
		return days;
	}

	public void setDays(Integer days) {
		this.days = days;
	}

	public String getContent() {

	}

	public void setContent(String content) {

	}

	public Date getLeaveDate() {

	}

	public void setLeaveDate(Date leaveDate) {

	}

	public void setRemark(String remark) {

	}

	public Integer getState() {
		return state;
	}

	public void setState(Integer state) {
		this.state = state;
	}
	
}

  

                   LeaveBill.hbm.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC 
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

</class>
</hibernate-mapping>

          4，项目包结构：

 

       

          5，新建 login.jsp 页面：

   

<%@ page language="java" contentType="text/html; charset=utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Insert title here</title>
</head>
<body>
	<h1>欢迎首页</h1>
</body>
</html>

      

         6，初始化 Activiti 工作流所需的23张表

                 a，新建 activiti.cfg.xml 文件

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
	<!-- 
		ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
		//连接数据库的配置
		processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
		processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/itcast0711activiti?useUnicode=true&characterEncoding=utf8");
		processEngineConfiguration.setJdbcUsername("root");
		processEngineConfiguration.setJdbcPassword("root");
		
		/**
		 	public static final String DB_SCHEMA_UPDATE_FALSE = "false";不能自动创建表，需要表存在
  			public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";先删除表再创建表
  			public static final String DB_SCHEMA_UPDATE_TRUE = "true";如果表不存在，自动创建表
		 */
		processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
	 -->
	<bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
		<!-- 连接数据的配置 -->
		<property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>
		<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/mi?useUnicode=true&characterEncoding=utf8"></property>
		<property name="jdbcUsername" value="root"></property>
		<property name="jdbcPassword" value="123"></property>
		<!-- 没有表创建表 -->
		<property name="databaseSchemaUpdate" value="true"></property>
	</bean>

</beans>

                  b，新建  TestActiviti 测试类，初始化数据表

package com.juyuan238.mi.test;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;

public class TestAaciviti {
	
	@Test
	public void createTable(){
		ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
		//工作流的核心对象,ProcessEnginee对象
		ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
		System.out.println("processEngine: "+processEngine);
	}
}

                 c，运行  TestActiviti 测试类，OK……

           这样的话，搭建的过程就整个完成了。可以运行Tomcat 服务器测试下，是否能够跑的通。下一节继续讲Activiti5.4在SSH框架的开发与使用……
