日志文件log4j.properties

log4j.rootLogger=INFO, 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

　　准备一个数据库，同时事先创建好数据库，比如我的是public_worlflow

代码部分

package com.java;

import org.flowable.engine.ProcessEngine;
import org.flowable.engine.ProcessEngineConfiguration;
import org.flowable.engine.impl.cfg.StandaloneProcessEngineConfiguration;
import org.junit.Test;

/**
 * @Description:

 * @Create: 2024/3/11 9:50
 */
public class HolidayRequest {

    @Test
    public void processTest(){
        ProcessEngineConfiguration cfg = new StandaloneProcessEngineConfiguration()
                .setJdbcUsername("root")
                .setJdbcPassword("qweiop1992")
                .setJdbcDriver("com.mysql.jdbc.Driver")
                //表结构不存在就创建
                .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        ProcessEngine processEngine = cfg.buildProcessEngine();
        System.out.println("processEngine="+processEngine);

    }
}

 初始化的表结构
