Tinyflow实现AI流程编排(实战篇)

背景：打造AI智能体，加速企业AI应用建设

此次从入门到实战，框架若依plus，JDK17，SpringBoot版本3.4.1

Tinyflow介绍

Tinyflow支持Java，引入对应的依赖即可；同时也支持前端，如Vue、React，一个好用的组件！

智能体编排类似Dify、Coze的工作流，支持自定义节点

Spring AI Alibaba也支持工作流搭建，基于Spring AI Alibaba Graph实现，但还在完善阶段！

demo版

需要源码加入技术群获取！

启动成功后，浏览器访问"http://localhost:port"

新增节点并测试

点击运行

点击保存

表中成功插入数据，执行成功！

完整的json结构，非常友好！

步骤一：引入依赖

$1$ pom.xml

xml 复制代码

<tinyflow.version>1.0.8</tinyflow.version>

引入版本

xml 复制代码

<dependency>
    <groupId>dev.tinyflow</groupId>
    <artifactId>tinyflow-java-core</artifactId>
    <version>${tinyflow.version}</version>
</dependency>

步骤二：表设计

$2$ ai_workflow

sql 复制代码

CREATE TABLE `ai_workflow` (  `flow_id` bigint NOT NULL COMMENT '流程id',  `flow_name` varchar(50) DEFAULT NULL COMMENT '流程名称',  `graph` json DEFAULT NULL COMMENT '节点数据',  `status` int DEFAULT '0' COMMENT '状态 0->草稿 1->发布',  `description` varchar(255) DEFAULT NULL COMMENT '描述内容',  `tenant_id` varchar(20) DEFAULT NULL COMMENT '租户id',  `create_dept` bigint DEFAULT NULL COMMENT '创建部门',  `create_by` bigint DEFAULT NULL COMMENT '创建者',  `create_time` datetime DEFAULT NULL COMMENT '创建时间',  `update_by` bigint DEFAULT NULL COMMENT '更新者',  `update_time` datetime DEFAULT NULL COMMENT '更新时间',  `del_flag` char(1) DEFAULT '0' COMMENT '删除标志（0代表存在 2代表删除）',  PRIMARY KEY (`flow_id`)) COMMENT='AI流程编排';

步骤三：代码生成

下载后，拷贝到对应的目录即可

步骤四：执行流程接口

$3$ AiWorkflowController

less 复制代码

@PostMapping("/excute")
public R<Map<String, Object>> excute(@RequestBody AiWorkflowExcuteBo bo) {  
    return R.ok(aiWorkflowService.excute(bo));
}

$4$ IAiWorkflowService

javascript 复制代码

 /**     
 * 执行流程     
 *     
 * @param bo     
 * @return     
 */    
 Map<String, Object> excute(AiWorkflowExcuteBo bo);

$5$ AiWorkflowServiceImpl

typescript 复制代码

 @Override
 public Map<String, Object> excute(AiWorkflowExcuteBo bo) 
 {       
     "请加入技术群获取"    
 }

步骤五：保存结果接口

$3$ AiWorkflowController

less 复制代码

  /**
  * 保存结果     
  *     
  * @param bo     
  * @return     
  */    
  @PostMapping("/saveResult")    
  public R<Void> saveResult(@RequestBody AiWorkflowBo bo) 
  { 
      return toAjax(aiWorkflowService.saveResult(bo));    
  }

步骤六：发布流程接口

$3$ AiWorkflowController

less 复制代码

 /**     
 * 发布流程     
 *     
 * @param flowId 流程id     
 * @return     
 */    
 @PutMapping("/release/{flowId}")    
 public R<Void> release(@PathVariable("flowId") Long flowId) 
 {
     return toAjax(aiWorkflowService.release(flowId));    
 }

步骤七：功能测试

查询接口
