我的XML如下如何添加結果集爲CSV文件中的駱駝
<camelContext trace="false" xmlns="http://camel.apache.org/schema/spring">
<propertyPlaceholder id="placeholder" location="classpath:application.properties" />
<!--Route:1 for POLLUX Data Processing -->
<route id="processPolluxData-Route" startupOrder="1">
<from uri="{{POLLUX_INPUT_PATH}}?noop=true"/>
<unmarshal ref="csvBindyDataformatForPolluxData"/>
<camel:bean ref="polluxDataController" method="processPolluxData"/>
<camel:log message="Line:${body}" loggingLevel="INFO"/>
<to uri="sqlComponent:{{sql.insertPolluxData}}?batch=true" />
</route>
<!-- Route:2 for RSI Data Processing -->
<route id="processRsiData-Route" startupOrder="2">
<from uri="{{RSI_INPUT_PATH}}?noop=true"/>
<unmarshal ref="csvBindyDataformatForRsiData"/>
<camel:bean ref="rsiDataController" method="processRsiData"/>
<camel:log message="Line:${body}" loggingLevel="INFO"/>
<to uri="sqlComponent:{{sql.insertRsiData}}?batch=true" />
</route>
<!-- Route for Global Data Processing -->
<route id="processGlobalData-Route" >
<from uri="sqlComponent:{{sql.selectOrder}}?consumer.useIterator=false" />
<camel:bean ref="globalDataController" method="processGlobalData" />
<marshal>
<csv delimiter=","/>
</marshal>
<log message="${body}" />
<setHeader headerName="camelFilename">
<constant>result.csv</constant>
</setHeader>
<to uri="{{GLOBAL_OUTPUT_PATH}}?fileExist=Append" />
</route>
我的SQL語句中給出的
sql.selectOrder=select STID,CLLTR,SOURCE from GSI_DEVL.POLLUX_DATA
bean類進行處理的結果集是
public class GlobalDataController {
List<Map<String, Object>> globalStationProccessedList = new ArrayList<Map<String, Object>>();
List<Map<String, Object>> globalStationMap = new ArrayList<Map<String, Object>>();
@SuppressWarnings("unchecked")
public List<Map<String, Object>> processGlobalData(Exchange exchange) throws Exception {
// System.out.println("Processing " + exchange.getIn().getBody());
globalStationMap = (List<Map<String, Object>>) exchange.getIn().getBody();
globalStationProccessedList.addAll(globalStationMap);
return globalStationProccessedList;
}
}
現在的問題是1個線數據transffered到CSV文件與database.But行的確切數目在路由2沒有數據追加到CSV文件 我使用駱駝2.16
您的解決方案工作!謝謝 但結果集在數據庫中包含34000行,在文件中我只得到2000行。是否有任何限制? 請幫忙 –
似乎很奇怪,因爲我不認爲有任何默認限制。在camel中,獲取結果集後,交換頭文件CamelSqlRowCount的值是多少?它是2000還是34000? –
你正在使用哪個版本的駱駝? –
