首先创建一个maven项目然后在pom.xml中添加以下依赖dependencies dependency groupIdorg.activiti/groupId artifactIdactiviti-engine/artifactId version5.19.0.2/version /dependency dependency groupIdorg.activiti/groupId artifactIdactiviti-spring/artifactId version5.19.0.2/version /dependency dependency groupIdorg.activiti/groupId artifactIdactiviti-bpmn-model/artifactId version5.19.0.2/version /dependency !-- https://mvnrepository.com/artifact/mysql/mysql-connector-java -- dependency groupIdmysql/groupId artifactIdmysql-connector-java/artifactId version8.0.14/version /dependency /dependencies接着就是生成25张表有两种方式。第一种是不使用xml配置文件的第二种是使用了配置文件的其中activiti.cfg.xml的名字不可以改变。activiti.cfg.xml中的内容为?xml version1.0 encodingISO-8859-1? beans xsi:schemaLocationhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance xmlnshttp://www.springframework.org/schema/beans bean classorg.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration idprocessEngineConfiguration property valuejdbc:mysql://localhost:3306/db_activiti?useSSLfalseamp;serverTimezoneUTC namejdbcUrl/ property valuecom.mysql.cj.jdbc.Driver namejdbcDriver/ property valueroot namejdbcUsername/ property value123456 namejdbcPassword/ property valuetrue namedatabaseSchemaUpdate/ /bean /beans执行junit单元测试便可看到数据库中多出来了25张表格。
