我在项目中使用Spring Integration。 根据我的要求,我必须同时调用两个存储过程。这是我的代码:
<int:service-activator ref="msgHandler" method="buildRequestBasedDataSource" />
<int-jdbc:stored-proc-outbound-gateway
id="PQIssueHistory-StoredProcedure-PQCOMMENTLOOKUP"
auto-startup="true"
data-source="routingDataSource"
stored-procedure-name="${PQIssueHistory-StoredProcedure-PQCOMMENTLOOKUP}"
skip-undeclared-results="true"
ignore-column-meta-data="true"
use-payload-as-parameter-source = "false"
expect-single-result="true" >
<int-jdbc:sql-parameter-definition name="P_CRDATTIM" direction="IN" type="VARCHAR" />
<int-jdbc:sql-parameter-definition name="P_RECORDCD" direction="IN" type="VARCHAR" />
<int-jdbc:sql-parameter-definition name="P_CRNODE" direction="IN" type="VARCHAR" />
<int-jdbc:parameter name="P_CRDATTIM" expression="#xpath(payload, '//CRDATTIM')" />
<int-jdbc:parameter name="P_RECORDCD" expression="#xpath(payload, '//RECORDCD')" />
<int-jdbc:parameter name="P_CRNODE" expression="#xpath(payload, '//CRNODE')" />
<int-jdbc:returning-resultset name="rowMapper" row-mapper="com.dsths.cs.awd.utils.ResultSetRowMapper"/>
</int-jdbc:stored-proc-outbound-gateway>
<int:service-activator ref="msgHandler" method="buildMessageFromExtSysResponseTestOne" />
<int:header-enricher default-overwrite="true" should-skip-nulls="true" >
<int:header name="${headerNames.originalPayload}" expression="payload" />
</int:header-enricher>
</int:chain>
<int:channel id="test" />
<int:chain input-channel="test" output-channel="PQIssueHistory-XsltTransformInputChannel" >
<int-jdbc:stored-proc-outbound-gateway
id="PQIssueHistory-StoredProcedure-PQHISTORYLOOKUP"
auto-startup="true"
data-source="routingDataSource"
stored-procedure-name="${PQIssueHistory-StoredProcedure-PQHISTORYLOOKUP}"
skip-undeclared-results="true"
ignore-column-meta-data="true"
use-payload-as-parameter-source = "false"
expect-single-result="true" >
<int-jdbc:sql-parameter-definition name="P_CRDATTIM" direction="IN" type="VARCHAR" />
<int-jdbc:sql-parameter-definition name="P_RECORDCD" direction="IN" type="VARCHAR" />
<int-jdbc:sql-parameter-definition name="P_CRNODE" direction="IN" type="VARCHAR" />
<int-jdbc:parameter name="P_CRDATTIM" expression="#xpath(payload, '//CRDATTIM')" />
<int-jdbc:parameter name="P_RECORDCD" expression="#xpath(payload, '//RECORDCD')" />
<int-jdbc:parameter name="P_CRNODE" expression="#xpath(payload, '//CRNODE')" />
<int-jdbc:returning-resultset name="rowMapper" row-mapper="com.dsths.cs.awd.utils.ResultSetRowMapper"/>
</int-jdbc:stored-proc-outbound-gateway>
<int:service-activator ref="msgHandler" method="buildMessageFromExtSysResponseTestTwo" />
</int:chain>
当我使用junit测试用例执行时,我能够毫无问题地点击存储过程。但是,当我尝试从GUI执行时(即在与UI集成之后),我收到以下错误:< / p>

从上面的例外情况可以看出,控件将进入错误通道。在这里,我只是想知道导致问题的sql查询。我打开了“DEBUG”。如果任何人可以分享他们关于如何进一步寻找/修复问题的想法,那就太棒了。
答案 0 :(得分:1)
阿肖克,我只能分享想法,因为我可能知道更少的springjdbc。但我认为导致问题的原因是驱动程序添加了一个声明,例如getUpdateCount。
首先,您可以创建一个类来扩展JdbcTemplate,但是复制所有内容并更改构造函数,使其与JdbcTemplate相同。我假设您可以看到JdbcTemplate的源代码。
其次,在第1020行,找出它是什么以及如何调用它。该异常从SQLException转换为您未向我们展示的其他内容。请告诉我们,我们知道顶级例外是什么。你使用的是什么版本的springjdbc?
第三,现在您可以修改代码以使用您自己的子类而不是JdbcTemlate,您可以修改代码。评论像警告一样的东西。您一步一步地从try {}块中的最后一行进行注释,其中异常被捕获并逐个进行。然后你应该能够找出驱动程序添加的额外SQL语句导致问题。
这只是一个想法。请告诉我们您的结果,我们可以继续。
答案 1 :(得分:0)
如果您的意思是想要查看发送到数据库的查询的实际内容,请使用间谍驱动程序;只是谷歌;有很多。或者使用WireShark或类似方法获取网络跟踪。
