Apache camel Apache Camel 2.18中的IN条款

apache-camel

Apache camel Apache Camel 2.18中的IN条款,apache-camel,camel-sql,Apache Camel,Camel Sql,我试图在路由中执行sql删除语句。查询包含一个IN子句，我想将一组值传递给IN子句。我正在使用camel-core和camel-jdbc2.18.1以及camel-sql2.18.0 from("direct:deleteRoute").setBody(simple("DELETE FROM TABLE_NAME WHERE ID IN (:#in:idSet)")).to(Constants.JDBC_DATA_SOURCE).end(); idSet的值通过路由调用direct:delet

我试图在路由中执行sql删除语句。查询包含一个IN子句，我想将一组值传递给IN子句。我正在使用camel-core和camel-jdbc2.18.1以及camel-sql2.18.0

from("direct:deleteRoute").setBody(simple("DELETE FROM TABLE_NAME WHERE ID IN (:#in:idSet)")).to(Constants.JDBC_DATA_SOURCE).end();

idSet的值通过路由调用

direct:deleteRoute

的键

idSet

传递到exchange的标头中

但是当我执行时，我得到以下异常

此堆栈跟踪来自组件。该组件使用标准的JDBCAPI，因此受到一些限制。其中之一就是你
在Camel中，您可以实现定制，使用uri参数prepareStatementStrategy注册它，以提供解析查询的定制逻辑，但我不建议这样做。这会导致很多陷阱

更好地使用组件，它使用

springjdbc

，并且自apachecamel 2.17以来就允许本机使用它

带有常数准备语句的示例：

from("direct:deleteIds")
        .to("sql:DELETE FROM TABLE_NAME WHERE ID IN (:#in:idSet)");

from("direct:deleteIds")
        .setBody(simple("DELETE FROM TABLE_NAME WHERE ID IN (:?in:idSet)")) // Note questionmark here for specifying parameter. This is difference against query in uri.  
        .to("direct:executeQuery");

from("direct:executeQuery")
        .setHeader(SqlConstants.SQL_QUERY, body())
        .to("sql:dummy?dataSource=#datasource");

从正文创建语句的示例：

from("direct:deleteIds")
        .to("sql:DELETE FROM TABLE_NAME WHERE ID IN (:#in:idSet)");

from("direct:deleteIds")
        .setBody(simple("DELETE FROM TABLE_NAME WHERE ID IN (:?in:idSet)")) // Note questionmark here for specifying parameter. This is difference against query in uri.  
        .to("direct:executeQuery");

from("direct:executeQuery")
        .setHeader(SqlConstants.SQL_QUERY, body())
        .to("sql:dummy?dataSource=#datasource");

您能否共享

常量.JDBC\u数据\u源变量中的内容？因为从stacktrace看来，它是JDBC组件，但您已经为SQL组件使用了参数语法。SQL组件使用：#
进行参数绑定，JDBC组件使用：？
。请注意：永远不要混合依赖版本，这可能会导致不可预测的行为。始终使用与Apache Camel版本相同的所有组件。谢谢@Bedla。我正在研究spring boot，如果我继续使用第二个示例，那么#datasource的值应该是多少。是表示数据源的bean的名称。#DataSource
是从注册表中查找数据源的引用（通常是Spring bean名称）。
