# 告警规则系统全流程可落地实施方案

## 📋 方案概述

基于现有系统架构和优化文档，整合告警规则、缓存同步、消息发布等所有优化策略，提供一个完整的、可直接落地的实施方案。

### 🎯 核心目标
- **统一规则管理**: 支持单体征、复合、复杂三类告警规则
- **高效缓存同步**: Redis三层缓存架构，TTL延长至24小时
- **消息发布优化**: 统一消息模型，支持多渠道分发
- **高并发处理**: 异步队列+批量处理，性能提升80%以上
- **管理界面友好**: 可视化规则配置向导

## 🏗️ 整体架构设计

```

## 🗄️ 数据库设计

### 1. 告警规则表优化 (t_alert_rules)

#### 1.1 向下兼容的表结构增强
```sql
-- 保持现有字段，新增扩展字段
ALTER TABLE `t_alert_rules` 
ADD COLUMN `rule_category` ENUM('SINGLE', 'COMPOSITE', 'COMPLEX') DEFAULT 'SINGLE' COMMENT '规则类型：单体征/复合/复杂',
ADD COLUMN `condition_expression` JSON COMMENT '复合条件表达式',
ADD COLUMN `time_window_seconds` INT DEFAULT 300 COMMENT '时间窗口(秒)',
ADD COLUMN `cooldown_seconds` INT DEFAULT 600 COMMENT '告警冷却期(秒)',
ADD COLUMN `priority_level` INT DEFAULT 3 COMMENT '优先级(1-5，数字越小优先级越高)',
ADD COLUMN `rule_tags` JSON COMMENT '规则标签，便于分类管理',
ADD COLUMN `effective_time_start` TIME COMMENT '生效开始时间',
ADD COLUMN `effective_time_end` TIME COMMENT '生效结束时间',
ADD COLUMN `effective_days` VARCHAR(20) DEFAULT '1,2,3,4,5,6,7' COMMENT '生效星期(1-7)',
ADD COLUMN `version` BIGINT DEFAULT 1 COMMENT '规则版本号',
ADD COLUMN `enabled_channels` JSON COMMENT '启用的通知渠道',
ADD INDEX idx_customer_category (`customer_id`, `rule_category`),
ADD INDEX idx_priority (`priority_level`),
ADD INDEX idx_physical_sign_active (`physical_sign`, `is_active`);
```

#### 1.2 规则条件表达式设计
```json
-- 单体征规则 (现有兼容)
{
  "rule_type": "single",
  "physical_sign": "heart_rate",
  "threshold_min": 60,
  "threshold_max": 120,
  "trend_duration": 3
}

-- 复合规则 (新增)
{
  "rule_type": "composite",
  "conditions": [
    {
      "physical_sign": "heart_rate",
      "operator": ">",
      "threshold": 120,
      "duration_seconds": 180
    },
    {
      "physical_sign": "blood_oxygen", 
      "operator": "<",
      "threshold": 90,
      "duration_seconds": 60
    }
  ],
  "logical_operator": "AND",
  "evaluation_window": 300
}

-- 复杂规则 (高级)
{
  "rule_type": "complex",
  "expression": "((heart_rate > 120 AND blood_oxygen < 90) OR (temperature > 38.5)) AND time_of_day BETWEEN '09:00' AND '17:00'",
  "variables": {
    "heart_rate": "health_data.heart_rate",
    "blood_oxygen": "health_data.blood_oxygen",
    "temperature": "health_data.temperature",
    "time_of_day": "CURRENT_TIME"
  }
}
```

### 2. 告警记录表增强 (t_alert_info)
```sql
ALTER TABLE `t_alert_info`
ADD COLUMN `rule_version` BIGINT COMMENT '规则版本',
ADD COLUMN `trigger_conditions` JSON COMMENT '触发条件详情',
ADD COLUMN `evaluation_context` JSON COMMENT '评估上下文',
ADD COLUMN `suppression_key` VARCHAR(128) COMMENT '抑制键',
ADD COLUMN `escalation_level` INT DEFAULT 0 COMMENT '升级级别',
ADD COLUMN `ack_required` BOOLEAN DEFAULT FALSE COMMENT '是否需要确认',
ADD COLUMN `auto_resolve` BOOLEAN DEFAULT FALSE COMMENT '是否自动恢复',
ADD INDEX idx_suppression (`suppression_key`),
ADD INDEX idx_escalation (`escalation_level`),
ADD INDEX idx_rule_version (`rule_id`, `rule_version`);
```

### 3. 缓存同步表 (新增)
```sql
CREATE TABLE `t_alert_cache_sync` (
  `id` BIGINT PRIMARY KEY AUTO_INCREMENT,
  `customer_id` BIGINT NOT NULL,
  `cache_key` VARCHAR(255) NOT NULL,
  `version` BIGINT NOT NULL DEFAULT 1,
  `last_sync_time` DATETIME DEFAULT CURRENT_TIMESTAMP,
  `sync_status` ENUM('pending', 'synced', 'failed') DEFAULT 'pending',
  `error_message` TEXT,
  UNIQUE KEY uk_customer_cache (`customer_id`, `cache_key`),
  INDEX idx_sync_status (`sync_status`),
  INDEX idx_last_sync (`last_sync_time`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='告警规则缓存同步状态表';
```

## 🚀 后端实现 (ljwx-boot)

### 2. 缓存同步增强版
```java
