activiti工作流入门

1，下载插件

插件下载地址：
Activiti Designer
http://Activiti.org/designer/update

在eclipse中输入以上地址：

下载完成后设置eclipses的window--preferences--activitie如下图所示

2，创建一个maven工程引入相关jar 版本可以自由选择

activation-1.1.jar activiti-bpmn-converter-5.13.jar activiti-bpmn-layout-5.13.jar activiti-bpmn-model-5.13.jar activiti-common-rest-5.13.jar activiti-engine-5.13.jar activiti-json-converter-5.13.jar activiti-rest-5.13.jar activiti-simple-workflow-5.13.jar activiti-spring-5.13.jar aopalliance-1.0.jar commons-dbcp-1.4.jar commons-email-1.2.jar commons-fileupload-1.2.2.jar commons-io-2.0.1.jar commons-lang-2.4.jar commons-pool-1.5.4.jar h2-1.3.170.jar hamcrest-core-1.3.jar jackson-core-asl-1.9.9.jar jackson-mapper-asl-1.9.9.jar javaGeom-0.11.0.jar jcl-over-slf4j-1.7.2.jar jgraphx-1.10.4.2.jar joda-time-2.1.jar junit-4.11.jar log4j-1.2.17.jar mail-1.4.1.jar mybatis-3.2.2.jar 内部依赖mybatis mysql-connector-java-5.1.5-bin.jar org.restlet-2.0.15.jar org.restlet.ext.fileupload-2.0.15.jar org.restlet.ext.jackson-2.0.15.jar org.restlet.ext.servlet-2.0.15.jar slf4j-api-1.7.2.jar slf4j-log4j12-1.7.2.jar spring-aop-3.1.2.RELEASE.jar spring-asm-3.1.2.RELEASE.jar spring-beans-3.1.2.RELEASE.jar spring-context-3.1.2.RELEASE.jar spring-core-3.1.2.RELEASE.jar spring-expression-3.1.2.RELEASE.jar spring-jdbc-3.1.2.RELEASE.jar spring-orm-3.1.2.RELEASE.jar spring-tx-3.1.2.RELEASE.jar

3.创建一个maven工程引入配置文件activiti.cfg.xml

<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">
    <bean id="processEngineConfiguration"
        class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

        <property name="jdbcDriver" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl"
            value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=utf8"></property>
        <property name="jdbcUsername" value="root"></property>
        <property name="jdbcPassword" value="root"></property>
        <property name="databaseSchemaUpdate" value="true"></property>
    </bean>
</beans>

4.创建23张表

方式一代码最简单，缺点 速度有点慢：

public void test() {         ProcessEngine pe = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml").buildProcessEngine();              System.out.println(pe);     }

方式二 特点快：

File file = new File("src/main/resource/activiti.cfg.xml"); InputStream in = new FileInputStream(file); ProcessEngineConfiguration .createProcessEngineConfigurationFromInputStream(in);

方式三：不使用配置文件activiti.cfg.xml

public static void main(String[] args) {         // 获取config对象         ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration                 .createStandaloneProcessEngineConfiguration();         // Jdbc设置         String jdbcDriver = "com.mysql.jdbc.Driver";         processEngineConfiguration.setJdbcDriver(jdbcDriver);         String jdbcUrl = "jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8";         processEngineConfiguration.setJdbcUrl(jdbcUrl);         String jdbcUsername = "root";         processEngineConfiguration.setJdbcUsername(jdbcUsername);         String jdbcPassword = "root";         processEngineConfiguration.setJdbcPassword(jdbcPassword);         // public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不自动创建新表         // public static final String DB_SCHEMA_UPDATE_CREATE_DROP =         // "create-drop";//每次运行创建新表         // public static final String DB_SCHEMA_UPDATE_TRUE = "true";设置自动对表结构进行改进和升级         // 设置是否自动更新         processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);         // 获取引擎对象         ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();         processEngine.close();          }
