Question

我尝试使用特定于集合类型= MAP

的Redis接收器

stream create tTEST_GF_SINK --definition "trigger --initialDelay=0 --fixedDelay=1 --timeUnit=MINUTES --payload= 'new Date().toString()' --outputType=application/json | 
  transform --expression='new java.util.Date().toString()'| 
  redis --collectionType=MAP --key=1" --deploy

对于所有其他集合类型，如LIST，SET，ZSET流能够写入这些redis接收器，但是当我使用MAP作为集合类型时，它会在redis_mapkey上抛出以下错误。

Answer 1

使用MAP集合，涉及两个键;地图存储在其下的关键字以及元素存储在地图中的关键字。

XD模块不会将mapKey公开为属性。您可以在上游添加标题扩充器以设置redis_mapKey标头，也可以编辑模块的配置以添加map-key-expression。

例如，像这样编辑xd/modules/sink/redis/config/redis.xml ...

<beans:beans profile="use-store-expression">
    <redis:store-outbound-channel-adapter
        map-key-expression="payload.substring(17)"
        key-expression="${keyExpression}" collection-type="${collectionType}"
        channel="input" connection-factory="redisConnectionFactory" />
</beans:beans>

...与

xd:>stream create foo --definition "time | redis --collectionType=MAP --key='foo'" --deploy

导致......

127.0.0.1:6379> hgetall "foo"
 1) "52"
 2) "2017-07-01 08:43:52"
 3) "53"
 4) "2017-07-01 08:43:53"
 5) "54"
 6) "2017-07-01 08:43:54"
 7) "55"
 8) "2017-07-01 08:43:55"
...

@Gary。我尝试了为header-richher添加redis_mapkey的建议。工作正常。

stream create tTEST_GF_SINK --definition“trigger --initialDelay = 0 --fixedDelay = 1 --timeUnit = MINUTES --payload ='new Date（）。toString（）' - outputType = application / json | header-enricher --headers = {\“redis_mapKey \”：\“payload.substring（17）\”} | transform --expression ='new java.util.Date（）。toString（）' | redis --collectionType = MAP --key = 1“--deploy

127.0.0.1:6379> hgetall 1

1）“ng（）”

2）“Sat Jul 01 23:29:16 EDT 2017”

带有集合类型MAP
