Activiti自动生成数据库

本文主要是介绍Activiti自动生成数据库，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1、环境

Mysql：5.5
JDK:1.8
Maven:3.8.1
actibpm:3.E-8
IDEA:2019.3
OS:Win10 64

2、插件的安装

1、由于我用的是IDEA：2019.3的系统，所以说在搜索actibpm插件的时候就无法搜到，只能选择手动安装插件。

2、在 https://plugins.jetbrains.com/plugin/7429-actibpm/versions/stable/17789 网站进行下载程序，得到如下所示安装包。

3、通过如下操作进行安装下载的安装包。

3、搭建程序框架

1、创建数据库。数据库名为：utf8mb4

2、创建mven工程，并进行设名字地址的输入。

3、pom.xml的编写

<?xml version="1.0" encoding="UTF-8"?>

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </releases>

</project>

4、log4j.properties日志文档的编写

*注：IDEA预编译时会有一些代码划红线的错误，并不会影响正常使用，不必理会。

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE
​
# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE
​
# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n
​
# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

5、activiti.cfg.xml文档的编写

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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">
​
    
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/activiti"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    </bean>
​
    
    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">
        
        <property name="dataSource" ref="dataSource"/>
        
        
        
        <property name="databaseSchemaUpdate" value="true"/>
    </bean>
</beans>

6、测试文档ActivitiTest的编写

package com.text;
​
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;
​
/**
 * 测试类
 *      作用：测试activiti所需要的25张表的生成
 */
public class ActivitiTest {
    @Test
    public void testGenTable(){
​
​
        // 引擎配置
        ProcessEngineConfiguration pec=ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        // 获取流程引擎对象
        ProcessEngine processEngine=pec.buildProcessEngine();
​
        //1、创建一个ProcessEngineConfiguration对象
       // ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
        //2、创建ProcesEngine对象
        // ProcessEngine processEngine = configuration.buildProcessEngine();
​
        //3.输出processEngine对象
        System.out.println(processEngine);
    }
}
​

7、运行测试即可

4、错误总结

由于项目中的代码好多是直接cope前人的代码，所以说在项目启动的时候bug也出现了许多，如果出现以下bug，只需要修改activiti.cfg.xml中的bean id即可。
