SpringBoot 集成 activiti的示例代码

SpringBoot 集成 activiti

基础环境搭建

添加依赖

org.activiti

activiti-spring-boot-starter-basic

6.0.0

添加配置文件

server:

tomcat:

uri-encoding: UTF-8

threads:

# 最大工作线程数，默认200

max: 1000

# 最小工作空闲线程数，默认10。（适当增大一些，以便应对突然增长的访问量）

min-spare: 30

port: 8082

spring:

datasource:

driver-class-name: com.mysql.cj.jdbc.Driver

url: jdbc:mysql://127.0.0.1:3306/activiti6-demo?characterEncoding=utf8&useSSL=false

username: root

password: 123456

activiti:

# 建表规则

# false 默认值。在启动时会对比数据库中保存的版本，如果没有表或版本不匹配则抛出异常。生产环境常用

# true 对activiti所有表进行更新操作，不存在则自动创建。开发常用

# create_drop 在启动时创建，在关闭时删除（必须手动关闭引擎，才能删除）。单元测试常用

# drop_create 在启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）

database-schema-update: true

# 启动的时候是否自动部署流程

check-process-definitions: false

# 历史数据

# none 不保存任何的历史数据，因此，在流程执行过程中，这是最高效的

# activity 级别高于none，保存流程实例与流程行为，其他数据不保存

# audit 除activity级别会保存的数据外，还会保存全部的流程任务及其属性。audit为history的默认值

# full 保存历史数据的最高级别，除了会保存audit级别的数据外，还会保存其他全部流程相关的细节数据，包括一些流程参数等

history-level: audit

# 不生成历史表 activiti6默认启用,activiti7默认关闭

db-history-used: true

现在运行项目报错

在启动类中排除安全配置就可以成功运行

@SpringBootApplication( exclude = SecurityAutoConfiguration.class)

public class ActivityDemoApplication {

public static void main(String[] args) {

SpringApplication.run(ActivityDemoApplication.class, args);

}

}
