⼯作流引擎flowable学习----idea创建maven请假流程例⼦1.创建简单maven项⽬
2.添加依赖
选择项⽬下的l⽂件，打开，加上⽅框⾥代码
<dependency>
<groupId>org.flowable</groupId>
<artifactId>flowable-engine</artifactId>
<version>6.4.1</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.40</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.21</version>
3.在项⽬test->src->resources中添加⽇志⽂件log4j.properties，写⼊该内容Logger=DEBUG, CA
log4j.appender.CA=org.apache.log4j.ConsoleAppender
log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern= %d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n
4.新建flowable的表
ProcessEngineConfiguration cfg = new StandaloneProcessEngineConfiguration()
.setJdbcUrl("jdbc:mysql://localhost:3306/flowable")
.setJdbcUsername("root")
.setJdbcPassword("root")
.setJdbcDriver("sql.jdbc.Driver")
.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
ProcessEngine processEngine = cfg.buildProcessEngine();
运⾏后表⽬录为
5.使⽤flowable创建⼀个简单的请假流程
5.1创建⼀个bpmn⽂件：l，将其放置于/src/main/resources下

<!--cn.test.first.CallExternalSystemDelegate是你的包-->
