我需要讀取一個包含csv文件（一個或多個文件）的目錄。我使用SpringBoot的駝峯，我需要將任何文件完全處理（沒有錯誤）移動到OUT目錄，但如果最後一個「到」路線失敗（拋出異常），我需要將文件移動到REFUSED目錄。駱駝讀取目錄，並通過完成任務結果選擇一個目的地
當我嘗試我的代碼，駱駝去不定式循環，繼續處理永遠同一個文件..

這是主代碼：
@Component
public class CamelContextConf extends RouteBuilder{
static final Logger logger = Logger.getLogger(CamelContextConf.class);
@Override
public void configure() throws Exception {
restConfiguration().component("servlet").dataFormatProperty("prettyPrint", "true") ;
CsvDataFormat csv = new CsvDataFormat();
csv.setDelimiter(";");
csv.setSkipHeaderRecord(true);
from("direct:csvprocessor")
.streamCaching()
.from("file:src/main/resources/data?move=OUT/VB/")
.unmarshal(csv)
.to("bean:myCsvHandler?method=doHandleCsvDataVB")
.onCompletion().onFailureOnly().to("file:src/main/reources/data/REFUSED").end()
.setBody(constant("OK"))
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200))
.setHeader(Exchange.CONTENT_TYPE, constant("text/html"));
logger.info("** Route config ok");
}
然後在myCsvHandler - >方法doHandleCsvDataVB我明確拋出一個異常來測試 失敗：
@Component
public class MyCsvHandler {
@Inject
AFVINCCrudRepository _entityManagerVINC;
@Inject
AFFileCrudRepository _entityManagerAfFile;
@Transactional(propagation = Propagation.REQUIRED , transactionManager="DbTransactionManagerVB")
public void doHandleCsvDataVB(List<List<String>> csvData) throws FileNotEvaluableException
{
//System.out.println("stampo..");
if (csvData.size() > 0){
AfFileEntity afbean = new AfFileEntity();
afbean.setNomeFile("test");
afbean.setDataImport(new java.sql.Timestamp(System.currentTimeMillis()));
afbean.setTipoFile("M");
afbean.setAfStatoFlusso("I");
_entityManagerAfFile.save(afbean);
long pkfile = afbean.getId();
System.out.println("pkfile: " + pkfile);
int i = 1; VincEntity vincBean = new VincEntity();
System.out.println(csvData.size());
for (List<String> rows : csvData){
..
_entityManagerVINC.save(..);
}
throw new FileNotEvaluableException("Il file non è nè una ...");
}
}
}
}
保存方法循環並繼續將數據保存在數據庫中。 出現了什麼問題？
非常感謝。
