Oinone请求调用链路

Oinone请求调用链路

请求格式与简单流程

在Oinone中请求数据存储在请求体中,以GQL的方式进行表示,也就是GQL格式的请求。

当我们发送一个GQL格式的请求,后端会对GQL进行解析,确定想要执行的方法,并对这个方法执行过程中所用到的模型进行构建,最后返回响应。

  • 请求
# 请求路径 pamirs/base
http://127.0.0.1:8090/pamirs/base

# 请求体内容
query{  
  petShopProxyBQuery{  
    sayHello(shop:{shopName:"cpc"}){
        shopName
    }
  }   
} 
  • 解析
# 简单理解
query 操作类型
petShopProxyBQuery 模块名称 + Query
sayHello 方法 fun
sayHello() 可以传入参数,参数名为 shop
shopName 需要得到的值
  • 响应
# data中的内容
"data": {
    "petShopQuery": {
        "hello": {
                "shopName": "cpc"
        }
    }
}

具体流程

Oinone是基于SpringBoot的,在Controller中处理请求

会接收所有以 /pamirs 开始的POST请求,/pamirs/后携带的是模块名

@RequestMapping(
        value = "/pamirs/{moduleName:^[a-zA-Z][a-zA-Z0-9_]+[a-zA-Z0-9]$}",
        method = RequestMethod.POST
)
public String pamirsPost(@PathVariable("moduleName") String moduleName,
                         @RequestBody PamirsClientRequestParam gql,
                         HttpServletRequest request,
                         HttpServletResponse response) {
        ........
}

整体脉络

Oinone请求调用链路
第四步执行中有两大重要的步骤,一步是动态构建GQL,一步是执行请求。

  • 函数之异步执行

    总体介绍 异步任务是非常常见的一种开发模式,它在分布式的开发模式中有很多应用场景如: 高并发场景中,我们一般采用把长流程切短,用异步方式去掉可以异步的非关键功能,缩小主流程响应时间,提升用户体验 异构系统的集成调用,通过异步任务完成解耦与自动重试 分布式系统最终一致性的可选方案 本文将介绍oinone是如何结合Spring+TbSchedule来完成异步任务 构建第一个异步任务 新建PetShopService和PetShopServiceImpl 1、 新建PetShopService定义updatePetShops方法 package pro.shushi.pamirs.demo.api.service; import pro.shushi.pamirs.demo.api.model.PetShop; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import java.util.List; @Fun(PetShopService.FUN_NAMESPACE) public interface PetShopService { String FUN_NAMESPACE = "demo.PetShop.PetShopService"; @Function void updatePetShops(List<PetShop> petShops); } 2、PetShopServiceImpl实现PetShopService接口并在updatePetShops增加@XAsync注解 package pro.shushi.pamirs.demo.core.service; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.PetShop; import pro.shushi.pamirs.demo.api.service.PetShopService; import pro.shushi.pamirs.meta.annotation.Fun; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.trigger.annotation.XAsync; import java.util.List; @Fun(PetShopService.FUN_NAMESPACE) @Component public class PetShopServiceImpl implements PetShopService { @Override @Function @XAsync(displayName = "异步批量更新宠物商店",limitRetryNumber = 3,nextRetryTimeValue = 60) public void updatePetShops(List<PetShop> petShops) { new PetShop().updateBatch(petShops); } } a. displayName = "异步批量更新宠物商店",定义异步任务展示名称b. limitRetryNumber = 3,定义任务失败重试次数,,默认:-1不断重试c. nextRetryTimeValue = 60,定义任务失败重试的时间数,默认:3d. nextRetryTimeUnit,定义任务失败重试的时间单位,默认:TimeUnitEnum.SECONDe. delayTime,定义任务延迟执行的时间数,默认:0f. delayTimeUnit,定义任务延迟执行的时间单位,默认:TimeUnitEnum.SECOND 修改PetShopBatchUpdateAction调用异步任务 引入PetShopService 修改conform方法,调用petShopService.updatePetShops方法 package pro.shushi.pamirs.demo.core.action; @Model.model(PetShopBatchUpdate.MODEL_MODEL) @Component public class PetShopBatchUpdateAction { @Autowired private PetShopService petShopService; @Action(displayName = "确定",bindingType = ViewTypeEnum.FORM,contextType = ActionContextTypeEnum.SINGLE) public PetShopBatchUpdate conform(PetShopBatchUpdate data){ List<PetShop> shops = ArgUtils.convert(PetShopProxy.MODEL_MODEL, PetShop.MODEL_MODEL,proxyList); // 调用异步任务 petShopService.updatePetShops(shops); }); return data; } } 不同应用如何隔离执行单元 在schedule跟模块部署一起的时候,多模块独立boot的情况下,需要做必要的配置。如果schedule独立部署则没有必要,因为全部走远程,不存在类找不到的问题 通过配置pamirs.zookeeper.rootPath,确保两组机器都能覆盖所有任务分片,这样不会漏数据 通过pamirs.event.schedule.ownSign来隔离。确保两组机器只取各自产生的数据,这样不会重复执行数据 pamirs: zookeeper: zkConnectString: 127.0.0.1:2181 zkSessionTimeout: 60000 rootPath: /demo event: enabled: true schedule: enabled: true ownSign: demo rocket-mq: namesrv-addr: 127.0.0.1:9876

  • 【OceanBase】后端部署使用 OceanBase 数据库(海扬/OB)
