springboot 2.2.0整合flowable 6.5.0

创建空的maven项目，并加入springboot 2.2.0、flowable依赖,以下是完整maven配置(pom.xml)

配置ProcessEngine

package com.satuo20.flowable.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;

/**
 * @author xiaodx
 */
@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;
    }
}

数据源及flowable 相关配置application.yml

server:
  port: 8080

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

启动类

package com.satuo20.flowable.main;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;


/**
 * @author xiaodx
 */
@SpringBootApplication
@ComponentScan("com.satuo20")
public class FlowableApp {
    public static void main(String[] args) {
        SpringApplication.run(FlowableApp.class,args);
    }
}

整合完成及总结

• 使用springboot整合flowable非常简单
• 在配置数据库时，如果抛出FlowableWrongDbException异常，请在spring.datasource.url中拼接参数nullCatalogMeansCurrent=true
