你可以使用 Goroutines 来并发处理一些独立的计算,从而优化这个函数。在 Go 中,协程非常轻量级,并且易于使用,可以有效地提高程序的性能。下面是对 GetUserHealthDiary
函数进行并发优化的示例:
func GetUserHealthDiary(userId int) ai_common.UserHealthDiary {
resp := ai_common.UserHealthDiary{}
date := time.Now().Format("2006-01-02") // 日期格式应该是标准的
dbData, isExist := dbrespository.GetUserHealthDiaryByUserId(userId, date)
if !isExist {
// create test data
dbData.UserID = userId
resp.RecordDate = dbData.RecordDate // 记录健康日记的日期,默认是当天
dbrespository.CreateUserHealthDiary(&dbData)
}
resp.RecordDate = dbData.RecordDate
var wg sync.WaitGroup
wg.Add(8) // 根据需要并发的函数数量进行调整
go func() {
defer wg.Done()
resp.HappinessIndex = getHappinessIndex(dbData.HappinessIndexID)
dbData.HappinessIndexID = resp.HappinessIndex.ID
}()
go func() {
defer wg.Done()
resp.PsychologicalPressure = getPsychologicalPressure(dbData.PsychologicalPressureID)
}()
go func() {
defer wg.Done()
resp.WorkStudyIntensity = getWorkStudyIntensity(dbData.WorkStudyIntensityID)
}()
go func() {
defer wg.Done()
resp.OvertimeSituation = getOvertimeSituation(dbData.OvertimeSituationID)
}()
go func() {
defer wg.Done()
resp.ElectronicDeviceTime = getElectronicDeviceTime(dbData.ElectronicDeviceTimeID)
}()
go func() {
defer wg.Done()
resp.ExerciseIntensity = getExerciseIntensity(dbData.ExerciseIntensityID)
}()
go func() {
defer wg.Done()
resp.BadSocialEmotions = getBadSocialEmotions(dbData.BadSocialEmotionsID)
dbData.BadSocialEmotionsID = resp.BadSocialEmotions.ID
}()
go func() {
defer wg.Done()
resp.SleepQuality = getSleepQuality(dbData.SleepQualityID)
dbData.SleepQualityID = resp.SleepQuality.ID
}()
wg.Wait()
for _, healthDiaryBadLiving := range dbData.HealthDiaryBadLiving {
resp.BadLivingBehaviors = append(resp.BadLivingBehaviors, healthDiaryBadLiving.BadLiving)
}
for _, healthDiaryBadSleep := range dbData.HealthDiaryBadSleep {
resp.BadSleep = append(resp.BadSleep, healthDiaryBadSleep.BadSleep)
}
for _, healthDiaryBadDining := range dbData.HealthDiaryBadDining {
resp.BadDining = append(resp.BadDining, healthDiaryBadDining.BadDining)
}
return resp
}
优化要点:
- Goroutines: 使用 Goroutines 并发处理每一个获取数据的函数。
- WaitGroup: 使用
sync.WaitGroup
来等待所有 Goroutines 完成。 - 避免重复代码: 对于重复的逻辑(例如更新 ID 的部分),如果有可能的话也考虑封装到函数中。
请根据你的具体需求和上下文适当调整上述示例,确保每个 Goroutine 的逻辑完整并正确处理共享资源的问题。
