在wso2esb和wso2dss

Question

分析錯誤我使用wso2esb 4.7.0和wso2dss 3.1.0.my .dbs文件中wso2dss工作，但是當我訪問它變成wso2esb它顯示在ESB終端考取一樣的錯誤：

LogMediator To: http://www.w3.org/2005/08/addressing/anonymous, WSAction: , SOAPAction: , MessageID: urn:uuid:0b6a1043-5904-4550-ba27-8e91da337bdd, Direction: response, Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Body><Fault><faultcode>soapenv:Server</faultcode><faultstring>java.lang.RuntimeException: Error obtaining parser from data source:DS Fault Message: Error in 'SQLQuery.processNormalQuery'

Current Request Name: select_all_test_operation 
Current Params: {limit=} 
Nested Exception:- 
java.lang.NumberFormatException: For input string: "" 
</faultstring><detail/></Fault></soapenv:Body></soapenv:Envelope> 

在wso2dss它顯示同一時間：

Caused by: javax.xml.stream.XMLStreamException: DS Fault Message: Error in 'SQLQuery.processNormalQuery' 
DS Code: DATABASE_ERROR 
Source Data Service:- 
Name: logindataservice

Current Request Name: select_all_test_operation 
Current Params: {limit=} 
Nested Exception:- 
java.lang.NumberFormatException: For input string: "" 

和在客戶端或在捲曲命令它顯示：

{"Fault":{"faultcode":"soapenv:Server","faultstring":"java.lang.RuntimeException: Error obtaining parser from data source:DS Fault Message: Error in 'SQLQuery.processNormalQuery'\nDS Code: DATABASE_ERROR\nSource Data Service:-\nName: logindataservice\nLocation: \/logindataservice.dbs\nDescription: N\/A\nDefault Namespace: http:\/\/ws.wso2.org\/dataservice\nCurrent Request Name: select_all_test_operation\nCurrent Params: {limit=}\nNested Exception:-\njava.lang.NumberFormatException: For input string: \"\"\n","detail":""}}* Closing connection #0 

我konw ot的解析錯誤，但我無法reslove this.What我應該做什麼？

問題出在您的數據服務或您發送的請求我相信。確保請求包含元素「限制」。看起來Data Services Server認爲它找不到輸入映射的值'limit'，所以它已經爲它分配了一個空字符串。但是你的sql查詢需要一個整數。所以，string-> int轉換失敗了。

另請參閱dbs中的query部分的行，重點關注input mappings。確保在輸入映射中設置的sqlType屬性是正確的。根據您的描述，它應該是INTEGER。
