# recommend-dps


推荐系统AB平台,无需单独部署，集成客户端、支持ab测试、ab分流多个策略，白名单、组件化部署、热部署、动态变更代码策略等功能。


依赖：
1.apollo
2.springboot


```
#ab测试分流策略    权重/分区
rec.dps.sence.XXXX.dpsAbLoad=weight/weightPartition 
#场景超过某个时间打印日志
rec.dps.sence.XXXX.dpsSenceTime=300
#白名单开关
rec.dps.sence.XXXX.group.dpsWhiteSwitch=true/false
#dpsAbLoad=weight时，表示权重，=weightPartition时，表示设备/用户 hashCode值之后的后2位
rec.dps.sence.XXXX.group.dpsWeight=10/10-20
#白名单路由
rec.dps.sence.XXXX.group.dpsWhiteId=1123

#default组下的召回层的耗时
rec.dps.sence.XXXX.group.default.recall.dpsTimeOut=200
#default组下的召回层的下的组件是并行还是穿行
rec.dps.sence.XXXX.group.default.recall.dpsParallel=true/false
#default组下的召回层的下的组件响应日志开关
rec.dps.sence.XXXX.group.default.recall.dpsLogDebug=true/false
#default组下的召回层的下的组件的default的权重，组件下只支持权重
rec.dps.sence.XXXX.group.default.recall.default.dpsWeight=10

接入教程

pom引入

```
<dependency>
    <groupId>com.dps</groupId>
    <artifactId>recommend-dps</artifactId>
    <version>XXXX.RELEASE</version>
</dependency>
```


apollo配置
```
apollo:
  bootstrap:
    eagerLoad:
      enabled: true
    enabled: true
    namespaces: dps_rec_sence,application
  meta: http://XXXX
app:
  id: dps-rec-square
```




启动项添加扫描
```
@ComponentScan(basePackages = {"com.dps.recommend"})

```

Request实体继承com.dps.recommend.beans.Request


controller的demo

```
@ResponseBody
@RequestMapping(value = "/square/same/item/rec", method = {RequestMethod.POST})
public DpsDataResult getRecSame(@RequestBody Request req, HttpServletRequest request) {
    try {

        DpsRequest dpsRequest = new DpsRequest(req);
        dpsRequest.getRequest().setSence("sameSquare");
        List list = dpsRecProcessor.process(dpsRequest);
        return DpsDataResult.successWithData(list);
    } finally {
        MDC.remove("requestId");
    }

}
```


 **组件** 
```
demo 的merage层
@Service
@LayerAnn(layer = LayerEnum.MERAGE)
public class CommunityMerage implements ProcessInterface {
    @Override
    public <R extends RecItemDps> List doProcess(DpsRequest dpsRequest, List<R> list) {

        return list;
    }
}
```
