数据流优化实施计划

For agentic workers: REQUIRED SUB-SKILL: Use compose:subagent (recommended) or compose:execute to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: 完善现有7条链路的TODO实现、新增业务链路、提升可靠性、添加链路间联动

Architecture: 基于Spring Event机制，补齐Handler中的TODO逻辑，新增手术→术后恢复等链路，为所有Handler添加重试和监控，实现链路间事件级联

Tech Stack: Spring Boot 4.0.6 + Spring Event + MyBatis-Plus + PostgreSQL

Task 6: 为所有Handler添加重试机制

Files:

• Create: healthlink-his-server/healthlink-his-application/src/main/java/com/healthlink/his/web/dataflow/config/EventRetryConfig.java

• Modify: 所有7个Handler添加重试逻辑

• Step 1: 创建重试配置类

package com.healthlink.his.web.dataflow.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import java.util.concurrent.Executor;

@Configuration
public class EventRetryConfig {

        executor.setCorePoolSize(4);
        executor.setMaxPoolSize(8);
        executor.setQueueCapacity(100);
        executor.setThreadNamePrefix("event-retry-");
        executor.initialize();
        return executor;
    }
}

• Step 2: 创建重试工具类

package com.healthlink.his.web.dataflow.util;

import lombok.extern.slf4j.Slf4j;
import java.util.function.Supplier;

@Slf4j
public class EventRetryUtil {

    public static <T> T executeWithRetry(String chainName, Supplier<T> action, int maxRetries) {
        Exception lastException = null;
        for (int i = 0; i <= maxRetries; i++) {
            try {
                return action.get();
            } catch (Exception e) {
                lastException = e;
                log.warn("Chain{} attempt {} failed: {}", chainName, i + 1, e.getMessage());
                if (i < maxRetries) {

                        Thread.sleep(1000L * (i + 1)); // 指数退避
                    } catch (InterruptedException ie) {
                        Thread.currentThread().interrupt();
                        throw new RuntimeException(ie);
                    }

        executeWithRetry(chainName, () -> { action.run(); return null; }, maxRetries);
    }
}

• Step 3: 修改DiagnosisSyncHandler添加重试

在onAdmissionSaved方法中使用重试工具：

EventRetryUtil.executeVoidWithRetry("1-DiagnosisSync", () -> {
    // 原有逻辑
}, 3);

• Step 4: 对其他6个Handler做相同修改

• Step 5: 编译验证

Run: mvn clean compile -DskipTests -pl healthlink-his-application Expected: BUILD SUCCESS

        this.orderId = orderId;
        this.reason = reason;
        this.triggerChain = triggerChain;
    }
}

• Step 2: 修改CriticalValueHandler在危急值时触发医嘱停止

@Autowired
