flowable工作流引擎之（一）整合springboot2+flowable

1.添加maven依赖

        <!--审批流-->
        <dependency>
            <groupId>org.flowable</groupId>
            <artifactId>flowable-spring-boot-starter-process</artifactId>
            <version>6.5.0</version>
        </dependency>

2.创建文件ProcessEngineConfig.java

注意文件存放路径和Application.java入口文件的相对位置，保证ProcessEngineConfig.java能正常注入。
文件内容如下：

package com.spt.config;

import org.flowable.engine.ProcessEngineConfiguration;
import org.flowable.spring.SpringProcessEngineConfiguration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import javax.sql.DataSource;

@Configuration
public class ProcessEngineConfig {
    /**
     * ProcessEngine 配置，其中DataSourceTransactionManager和DataSource自动注入
     * @param dataSourceTransactionManager
     * @param dataSource
     * @return
     */
    @Bean
    public SpringProcessEngineConfiguration springProcessEngineConfiguration(DataSourceTransactionManager dataSourceTransactionManager, DataSource dataSource) {
        SpringProcessEngineConfiguration springProcessEngineConfiguration = new SpringProcessEngineConfiguration();
        springProcessEngineConfiguration.setDataSource(dataSource);
        springProcessEngineConfiguration.setTransactionManager(dataSourceTransactionManager);

        //不添加此项配置，在没创建表时，会抛出FlowableWrongDbException异常
        springProcessEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        return springProcessEngineConfiguration;
    }
}

修改application.yml

添加如下配置

flowable:
  #关闭定时任务JOB
  async-executor-activate: false
  #  将databaseSchemaUpdate设置为true。当Flowable发现库与数据库表结构不一致时，会自动将数据库表结构升级至新版本。
  database-schema-update: true
