08-Flowable SpringBoot2.X集成

1. 添加pom依赖

主要依赖如下：

<parent>
	<groupId>org.springframework.bootgroupId>
	<artifactId>spring-boot-starter-parentartifactId>
	<version>2.1.1.RELEASEversion>
	<relativePath/>

<properties>
	<java.version>1.8java.version>
	<flowable.version>6.4.0flowable.version>

注意事项
在flowable与springboot2.x集成过程中，flowable相关表自动创建不能成功，发现是mysql驱动引起的。springboot2.x的mysql驱动是 mysql-connector-java 6(com.mysql.cj.jdbc.Driver)，jar包依赖为6以上版本。将mysql驱动改为mysql-connector-java 5(com.mysql.jdbc.Driver)，jar包依赖改为6以下版本，flowable相关表可以自动创建成功

2. application.yml文件配置

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/activiti_springboot?characterEncoding=UTF-8
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
#flowable:
#  database-schema-update: create-drop
 # check-process-definitions: false

3. 启动

启动引导类，启动成功后，观察mysql数据库，可以查看到自动生成的flowable相关数据表。
