这里使用的springboot2.0.6的版本，activiti为6.0.0的版本

添加processes目录

SpringBoot集成activiti默认会从classpath下的processes目录下读取流程定义文件，所以需要在src/main/resources目录下添加processes目录，并在目录中创建流程文件

application.yml

spring:
  activiti:
    check-process-definitions: true #自动检查、部署流程定义文件
    database-schema-update: true #自动更新数据库结构
    #流程定义文件存放目录
    process-definition-location-prefix: classpath:/processes/ 
    #process-definition-location-suffixes: #流程文件格式
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/taosir_process?useUnicode=true&useSSL=false&characterEncoding=utf8
    username : root
    password : root
    initsize : 10
    maxActive : 20
    minIdle : 10
    maxWait : 120000
    poolPreparedStatements : false
    maxOpenPreparedStatements : -1
    validationQuery : select 1
    testOnborrow : true
    testOnReturn : true
    testWhileIdle : true
    timeBetweenEvictionRunsMillis : 120000
server:
  port: 8764

启动类，注意@SpringBootApplication注解需要设置exclude属性

package cn.zytao.taosir.process;

import org.activiti.spring.boot.SecurityAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(exclude = SecurityAutoConfiguration.class)
public class ProcessApplication {
    public static void main(String[] args) {
        SpringApplication.run(ProcessApplication.class, args);
    }
}
