一、Flowable如何集成Spring

1.1 Flowable集成Spring+SpringMvc

1. POM文件添加以下代码
2. 6.8.0 使用mybatis 3.5.7即可，可根据自身对应mybatis版本进行更换，如果你没有自己写的插件等功能，建议升级mybatis版本，如果是老项目，建议使用低版本flowable，例如6.7.2

        <dependency>
			<groupId>org.flowable</groupId>
			<artifactId>flowable-engine</artifactId>
			<version>6.8.0</version>
        </dependency>
        <!-- 6.8.0 使用mybatis 3.5.7即可，可根据自身对应mybatis版本进行更换-->
		<dependency>
			<groupId>org.mybatis</groupId>
			<artifactId>mybatis</artifactId>
			<version>3.5.7</version>
		</dependency>

3.注入对应服务类,直接把以下内容复制即可，数据库要自己去替换我的代码

<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">
	<!-- 数据源配置 -->
	<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		init-method="init" destroy-method="close">
		<property name="driverClassName" value="${baseDataSource.driverClassName}" />
		<property name="url" value="${baseDataSource.url}" />
		<property name="username" value="${baseDataSource.username}" />
		<property name="password" value="${baseDataSource.password}" />
		<property name="maxActive" value="${baseDataSource.maxActive}" />
	</bean>
	
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <bean id="processEngineConfiguration" class="org.flowable.spring.SpringProcessEngineConfiguration">
        <property name="dataSource" ref="dataSource" />
        <property name="transactionManager" ref="transactionManager" />
        <property name="databaseSchemaUpdate" value="true" />
        <property name="asyncExecutorActivate" value="false" />
        <property name="activityFontName" value="宋体"/>
        <property name="annotationFontName" value="宋体"/>
        <property name="labelFontName" value="黑体"/>
    </bean>

    <bean id="processEngine" class="org.flowable.spring.ProcessEngineFactoryBean">
        <property name="processEngineConfiguration" ref="processEngineConfiguration"/>
    </bean>
    
    <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService"/>
    <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService"/>    
    <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService"/>
    <bean id="managementService" factory-bean="processEngine" factory-method="getManagementService"/>
</beans>

1.2 Flowable集成SpringBoot

flowable集成SpringBoot的办法可谓是相当简单，只需要引用自动的依赖即可

POM文件添加以下代码

        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>6.8.0</version>
        </dependency>

1.3 Flowable如何兼容Mysql5低版本

Flowable不兼容的原因是执行SQL脚本日期等问题导致，可以修改执行SQL的脚本即可，也可跟换执行器的版本，使用以下操作，让其支持低版本
使用liquibase-core 4.5.0版本，以便支持低版本数据库

 <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter</artifactId>
            <version>6.8.0</version>
            <exclusions>
                <exclusion>
                    <groupId>org.liquibase</groupId>
                    <artifactId>liquibase-core</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-core</artifactId>
            <version>4.5.0</version>
        </dependency>
