SpringXD - Gemfire中的错误是接收器

标签： spring spring-xd gemfire geode

我正在尝试在springXD中设置流。

gemfire安装在10.99.40.60机器上，springXD安装在我的LOCAL VM中。

        xd:>stream create --name gemfiredemo --definition "http --port=9090 | gemfire-server --host=10.99.40.60--port=10334 --useLocator=true   
    --regionName=region --keyExpression=payload.getField('symbol')" --deploy   

Created and deployed new stream 'gemfiredemo'

我在我的本地VM机器上运行spring XD ...

从VM发布任何数据时：

    xd:>http post --target http://localhost:9090 --data {"symbol":"ORCL","price":38}
    > POST (text/plain;Charset=UTF-8) http://localhost:9090 {"symbol":"ORCL","price":38}
    > 500 INTERNAL_SERVER_ERROR
    > 500 INTERNAL_SERVER_ERROR  
Error sending data '{"symbol":"ORCL","price":38}' to 'http://localhost:9090'

实际错误日志显示：

我不确定您期望的有效负载类型...... 

--keyExpression=payload.getField('symbol')

但是，如果你添加

--inputType='application/x-java-object;type=java.util.HashMap'

到您的接收器定义并添加

--contentType application/json

到您的http post请求，然后您可以使用

--keyExpression=payload.symbol

运行时会自动将json转换为地图。
