我的XML如下如何添加结果集为CSV文件中的骆驼
<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语句中给出的
sql.selectOrder=select STID,CLLTR,SOURCE from GSI_DEVL.POLLUX_DATA
bean类进行处理的结果集是
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;
}
}
现在的问题是1个线数据transffered到CSV文件与database.But行的确切数目在路由2没有数据追加到CSV文件 我使用骆驼2.16
您的解决方案工作!谢谢 但结果集在数据库中包含34000行,在文件中我只得到2000行。是否有任何限制? 请帮忙 –
似乎很奇怪,因为我不认为有任何默认限制。在camel中,获取结果集后,交换头文件CamelSqlRowCount的值是多少?它是2000还是34000? –
你正在使用哪个版本的骆驼? –
