準備材料下

activiti-5.17.0

1.添加Activiti5 的jar包或Maven依賴

Jar包方式

通過上述下載鏈接下載Activiti后，解壓得到如下目錄：

?

把libs的jar包添加到你的工程中并Build Path?

Maven方式

pom.xml 如下

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.demo.activiti</groupId><artifactId>practice01</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>practice01</name><url>http://maven.apache.org</url><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><activiti-version>5.18.0</activiti-version></properties><dependencies><dependency><groupId>org.activiti</groupId><artifactId>activiti-engine</artifactId><version>${activiti-version}</version></dependency><dependency><groupId>org.activiti</groupId><artifactId>activiti-spring</artifactId><version>${activiti-version}</version></dependency><dependency><groupId>org.codehaus.groovy</groupId><artifactId>groovy-all</artifactId><version>2.4.3</version></dependency><dependency><groupId>com.h2database</groupId><artifactId>h2</artifactId><version>1.3.168</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>1.7.6</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-jdk14</artifactId><version>1.7.6</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.18</version></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>4.11</version><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>2.3.2</version><configuration><source>1.6</source><target>1.6</target></configuration></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-eclipse-plugin</artifactId><inherited>true</inherited><configuration><classpathContainers><classpathContainer>org.eclipse.jdt.USER_LIBRARY/Activiti Designer Extensions</classpathContainer></classpathContainers></configuration></plugin></plugins></build>
</project>

2.初始化數(shù)據(jù)庫

package practice01;import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;public class TestActiviti {/*** 使用代碼創(chuàng)建工作流程所需要的24張表*/@Testpublic void createTable() {//創(chuàng)建工作流引擎配置對象ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();//鏈接數(shù)據(jù)庫的配置processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");processEngineConfiguration.setJdbcUrl("jdbc:mysql://127.0.0.1:3306/activiti_practive01?useunicode=true&characterEncoding=utf8");processEngineConfiguration.setJdbcUsername("root");processEngineConfiguration.setJdbcPassword("xxxx");/**public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不創(chuàng)建public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop"//先刪除后創(chuàng)建public static final String DB_SCHEMA_UPDATE_TRUE = "true"//創(chuàng)建表
*/processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);//創(chuàng)建工作流程引擎ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();System.out.println(processEngine);}
}

備注：在Activiti中，在創(chuàng)建核心的流程引擎對象時會自動建表。如果成行正常執(zhí)行，mysql會自動建庫，然后創(chuàng)建24張表

3.添加并指定配置文件

在Activiti中5 中定制流程必定會操作到數(shù)據(jù)庫，如果都像上面那樣寫一大段代碼會非常麻煩，所以我們可以把數(shù)據(jù)庫配置寫入配置文件

在Activiti5 的官方示例中并沒有現(xiàn)成的配置文件，所以先得找到activi-rest\WEB-INF\classes下有。

activiti.cofg.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:jee="http://www.springframework.org/schema/jee" xmlns:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsdhttp://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><!-- 工作流引擎配置對象 --><bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration"><property name="jdbcDriver" value="com.mysql.jdbc.Driver"/><property name="jdbcUrl" value="jdbc:mysql://127.0.0.1:3349/activiti_practive01?useunicode=true&characterEncoding=utf8"/><property name="jdbcUsername" value="root"/><property name="jdbcPassword" value="xxxx"/><property name="databaseSchemaUpdate" value="true"/></bean></beans>

ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");//創(chuàng)建工作流程引擎ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();System.out.println(processEngine);

3.2 log4j.properties 日志配置文件

把上述兩個文件放在resouces目錄即可。
