在合同与文档管理场景中,我们基于 Calendar Kit 构建全自动时效管理系统,核心实现代码如下:

 

typescript

// 1. 日历系统初始化

const docCalendar = await calendar.create({

  accountType: calendar.AccountType.ENTERPRISE,

  syncConfig: {

    frequency: calendar.SyncFrequency.REALTIME,

    conflictResolution: calendar.ConflictResolution.SERVER_WINS

  },

  enterpriseFeatures: {

    resourceBooking: true,

    compliance: {

      retentionPolicy: 3650,

      auditLogging: true

    }

  }

})

 

// 2. 文档关键事件自动编排

async function scheduleDocMilestones(doc) {

  const eventGroup = await docCalendar.createEventSeries({

    title: `[${doc.type}] ${doc.title}`,

    baseEvent: {

      start: doc.effectiveDate,

      end: doc.expiryDate,

      timezone: 'Asia/Shanghai',

      reminders: [

        { type: calendar.ReminderType.PUSH, minutes: 1440 },

        { type: calendar.ReminderType.EMAIL, minutes: 4320 }

      ]

    },

    rules: [

      {

        type: 'REVIEW',

        pattern: '0 0 1 * *', // 每月1号

        endCondition: { occurrences: 12 }

      },

      {

        type: 'PAYMENT',

        dates: extractPaymentDates(doc),

        autoReschedule: true

      }

    ],

    attachments: [

      {

        uri: doc.uri,

        permissions: 'VIEW',

        cloudPreview: true

      }

    ]

  })

 

  // 3. 智能冲突检测

  const conflictCheck = await docCalendar.checkConflicts({

    timeRange: [doc.effectiveDate, doc.expiryDate],

    calendars: ['primary', 'legal_dept'],

    minConfidence: 0.7

  })

}

 

// 4. 自然语言事件解析

const nlProcessor = calendar.createNLParser({

  models: ['legal', 'finance'],

  timezoneAware: true,

  onParse: (text) => {

    return {

      title: extractTitle(text),

      dates: detectDates(text),

      participants: findSigners(text)

    }

  }

})

 

// 5. 跨设备同步控制

const syncEngine = new calendar.SyncManager({

  strategy: calendar.SyncStrategy.DELTA,

  devices: ['phone', 'tablet', 'pc'],

  encryption: {

    algorithm: 'SM4',

    keyRotation: 'WEEKLY'

  },

  conflictHandler: (events) => {

    return events.sort((a,b) =>

      b.lastModified - a.lastModified

    )[0]

  }

})

//关键技术组件:

 

//法律时效计算:

 

typescript

calendar.registerLegalRules({

  jurisdiction: 'CN',

  rules: {

    noticePeriods: {

      termination: '30D',

      appeal: '15D'

    },

    holidays: holidayCalendar

  }

})

//智能提醒优化:

 

typescript

calendar.optimizeReminders({

  userHabits: analyzeUserResponse(),

  deviceUsage: checkActiveDevices(),

  smartDelay: [15, 30, 60] // 分钟

})

//多日历聚合:

 

typescript

const unifiedView = calendar.createUnifiedView({

  sources: ['legal', 'project', 'personal'],

  colorCoding: true,

  conflictHighlight: true

})

//企业级扩展方案:

 

//审批工作流:

 

typescript

calendar.enableApprovals({

  roles: {

    reviewer: 'LEADER',

    finalizer: 'LEGAL'

  },

  escalation: {

    timeout: '2D',

    nextInChain: true

  }

})

//区块链存证:

 

typescript

calendar.enableNotarization({

  chain: 'Hyperledger',

  events: ['CREATE', 'MODIFY', 'DELETE'],

  proofTemplate: 'legal_v1'

})

//AI预测调度:

 

typescript

calendar.enableAIScheduling({

  model: 'timeslot_prediction',

  factors: [

    'participant_availability',

    'document_complexity'

  ],

  bufferTime: '30M'

})

//优化实践建议:

 

//性能调优:

 

typescript

calendar.setSyncPolicy({

  batchSize: 50,

  throttle: 'AUTO',

  mobileData: 'METADATA_ONLY'

})

//存储优化:

 

typescript

calendar.configureStorage({

  maxEvents: 10000,

  attachmentPolicy: 'CLOUD_FIRST',

  cleanupFrequency: 'WEEKLY'

})

 

典型应用场景:

合同关键节点自动提醒

法律时效智能计算

文档审批流程日历化

多时区会议调度
