Built for distributed, autonomous behavior and dynamic workflows.项目地址: https://gitcode.com/GitHub_Trending/ji/jidoJido是Elixir的自主代理框架专为工作流和多智能体系统构建。本案例将展示如何利用Jido的核心功能快速搭建一个灵活高效的自动化工作流审批系统帮助企业简化审批流程、提高工作效率。为什么选择Jido构建审批系统Jido框架为审批系统提供了多项关键特性状态驱动的工作流通过FSM有限状态机策略实现清晰的审批状态流转确保流程的规范性和可追溯性多智能体协作支持创建不同角色的审批代理如部门经理、财务、CEO等实现复杂的层级审批流程灵活的指令系统使用Directive机制处理审批任务分配、通知发送等副作用操作持久化存储内置的存储模块lib/jido/storage/确保审批状态不会因系统重启而丢失可观测性完整的事件跟踪和日志系统便于监控审批流程和排查问题审批系统核心组件设计1. 审批状态管理审批系统的核心是状态管理Jido的FSM策略非常适合这种场景。我们可以定义以下审批状态待提交 → 待部门审批 → 待财务审批 → 待CEO审批 → 已批准/已拒绝通过Jido的状态操作模块lib/jido/agent/state_ops.ex我们可以轻松实现状态之间的转换逻辑。2. 审批代理设计为系统中的不同角色创建专用代理提交者代理负责发起审批请求跟踪审批进度审批者代理处理分配给自己的审批任务支持批准/拒绝操作协调者代理管理整个审批流程负责任务分配和状态同步Jido的代理管理功能lib/jido/agent.ex提供了启动、停止和监控代理的完整接口# 启动审批协调者代理 {:ok, coordinator_pid} Jido.start_agent(ApprovalCoordinator, id: approval-coordinator)3. 审批流程控制利用Jido的工作流编排能力lib/jido/orchestration.md我们可以实现以下审批流程控制串行审批按层级依次进行审批并行审批多个角色同时审批条件审批根据金额、类型等条件动态调整审批流程Jido的指令系统lib/jido/agent/directive.ex可以用来发送审批通知、分配任务# 发送审批任务指令 {:ok, directive} Directive.SpawnAgent.new( agent: ApprovalAgent, id: dept-manager-approval, params: %{approval_id: AP-12345, approver: dept-manager-1} )系统实现步骤步骤1定义审批状态和事件首先我们需要定义审批流程中的状态和可能触发的事件defmodule ApprovalAgent do use Jido.Agent.Strategy.FSM # 定义状态 initial_state :pending_submission # 定义状态转换规则 def transitions do %{ pending_submission: %{submit: :pending_department_approval}, pending_department_approval: %{approve: :pending_finance_approval, reject: :rejected}, # 更多状态转换规则... } end # 处理提交事件 def handle_event(:submit, params, state) do new_state transition(state, :submit) directives [ Directive.SendNotification.new( to: params.department_manager, message: New approval request: #{params.title} ) ] {new_state, directives} end # 更多事件处理函数... end步骤2实现审批代理创建处理实际审批逻辑的代理模块defmodule DepartmentApprovalAgent do use Jido.Agent def cmd(agent, {:approve, comment}) do # 更新审批状态 new_agent AgentStateOps.put(agent, :status, :approved) new_agent AgentStateOps.put(agent, :approver_comment, comment) # 生成下一步指令提交给财务审批 directives [ Directive.ForwardToAgent.new( agent_id: finance-approval-agent, action: {:approve_request, agent.state.request} ) ] {new_agent, directives} end def cmd(agent, {:reject, comment}) do # 处理拒绝逻辑 new_agent AgentStateOps.put(agent, :status, :rejected) new_agent AgentStateOps.put(agent, :approver_comment, comment) directives [ Directive.SendNotification.new( to: agent.state.requester, message: Your request was rejected: #{comment} ) ] {new_agent, directives} end end步骤3配置工作流协调使用Jido的编排功能设置审批流程的协调逻辑defmodule ApprovalCoordinator do use Jido.Agent def cmd(agent, {:start_approval, request}) do # 生成审批ID approval_id AP-#{Jido.Id.generate()} # 创建审批记录 new_agent AgentStateOps.put(agent, approval_id, %{ status: :pending, request: request, history: [] }) # 启动部门审批代理 directives [ Directive.SpawnAgent.new( agent: DepartmentApprovalAgent, id: #{approval_id}-dept, params: %{approval_id: approval_id, request: request} ) ] {new_agent, directives} end # 处理审批状态更新 def cmd(agent, {:update_status, approval_id, status, comment}) do # 更新审批历史 new_agent AgentStateOps.update_in(agent, [approval_id, :history], fn history - [ %{ timestamp: DateTime.utc_now(), status: status, comment: comment, approver: Jido.Agent.current_agent_id() } | history ] end) # 更新当前状态 new_agent AgentStateOps.put(new_agent, [approval_id, :status], status) {new_agent, []} end end步骤4集成持久化存储配置Jido的存储模块确保审批数据持久化# config/config.exs config :jido, storage: [ approval_data: [ adapter: Jido.Storage.Ets, table: :approval_data, options: [persistence: true] ] ]在代理中使用存储defmodule ApprovalAgent do use Jido.Agent def cmd(agent, :persist_state) do # 将当前状态保存到存储 directives [ Directive.StoreState.new( storage: :approval_data, key: agent.id, data: agent.state ) ] {agent, directives} end # 从存储恢复状态 def cmd(agent, :restore_state) do case Jido.Storage.get(:approval_data, agent.id) do {:ok, state} - {AgentStateOps.replace(agent, state), []} {:error, :not_found} - {agent, []} end end end系统扩展与优化1. 批量审批功能利用Jido的并行工作流能力guides/orchestration.md实现批量审批处理def cmd(agent, {:batch_approve, approval_ids}) do # 为每个审批ID生成并行审批指令 directives Enum.map(approval_ids, fn id - Directive.SpawnAgent.new( agent: BatchApprovalAgent, id: batch-#{id}, params: %{approval_id: id} ) end) # 添加等待所有审批完成的指令 directives directives [ Directive.AwaitAll.new( agent_ids: Enum.map(approval_ids, batch-#{1}), timeout: :timer.minutes(30) ) ] {agent, directives} end2. 审批超时处理使用Jido的调度功能lib/jido/scheduler.ex添加审批超时处理def cmd(agent, {:set_approval_timeout, approval_id, timeout_minutes}) do directives [ Directive.Schedule.new( id: timeout-#{approval_id}, at: DateTime.add(DateTime.utc_now(), timeout_minutes, :minute), action: {:escalate_approval, approval_id} ) ] {agent, directives} end # 处理超时升级 def cmd(agent, {:escalate_approval, approval_id}) do approval AgentStateOps.get(agent, approval_id) directives [ Directive.SendNotification.new( to: approval.escalation_contact, message: Approval #{approval_id} has timed out. Please handle immediately. ), Directive.ForwardToAgent.new( agent_id: approval.escalation_agent, action: {:approve_request, approval.request} ) ] {agent, directives} end部署与监控部署配置Jido提供了简单的部署配置方式在mix.exs中添加依赖defp deps do [ {:jido, git: https://gitcode.com/GitHub_Trending/ji/jido, tag: v0.1.0} ] end监控与调试利用Jido的调试工具lib/jido/debug.ex监控审批流程# 开启代理调试模式 Jido.debug(approval_agent_pid) # 获取审批流程调试日志 logs Jido.get_debug_logs(approval_agent_pid)Jido的可观测性指南guides/observability.md提供了更多关于系统监控和性能优化的信息。总结通过Jido框架我们可以快速构建一个功能完善、灵活可扩展的自动化工作流审批系统。Jido的状态管理、多智能体协作和工作流编排能力为复杂审批流程提供了强大的技术支持。无论是简单的单级审批还是复杂的多级并行审批Jido都能提供简洁而强大的解决方案。要了解更多Jido的高级特性可以参考官方指南FSM策略深入探讨插件开发指南传感器使用指南【免费下载链接】jido Autonomous agent framework for Elixir.
