软件环境要求
-
JDK1.6或者更高版本l
-
支持的数据库有:h2, mysql, oracle, postgres, mssql, db2等。
-
支持activiti5运行的jar包
-
开发环境为Eclipse3.7或者以上版本
Activiti5 所需jar
-
需要mysql驱动jar包
-
activity5jar包:activiti-5.13\wars\activiti-rest\WEB-INF\lib 中获取
初始化数据库
第一种方式执行sql脚本:
activiti.mysql.create.history.sql
activiti.mysql.create.identity.sql
activiti.mysql.create.engine.sql

//1.创建Activiti配置对象的实例
ProcessEngineConfigurationconfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
//2.设置数据库连接信息
// 设置数据库地址
configuration.setJdbcUrl(
"jdbc:mysql://localhost:3306/testactiviti?createDatabaseIfNotExist&useUnicode=true&characterEncoding=utf8"
);
// 数据库驱动
configuration.setJdbcDriver(
"com.mysql.jdbc.Driver"
);
// 用户名
configuration.setJdbcUsername(
"root"
);
// 密码
configuration.setJdbcPassword(
""
);
// 设置数据库建表策略
/**
* DB_SCHEMA_UPDATE_TRUE:如果不存在表就创建表,存在就直接使用
* DB_SCHEMA_UPDATE_FALSE:如果不存在表就抛出异常
* DB_SCHEMA_UPDATE_CREATE_DROP:每次都先删除表,再创建新的表
*/
configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
//3.使用配置对象创建流程引擎实例(检查数据库连接等环境信息是否正确)
ProcessEngineprocessEngine = configuration.buildProcessEngine();
System.out.println(processEngine);
