我有一条基本的骆驼路线(在 karaf 中运行),这条路线从 SQL 表中返回一个 ID 列表,当连接到 SQL Server 2012 时,该路线按预期工作,
路线:
private static final String GET_PRODUCTS_QUERY = "select PRODUCT_ID,PRODUCT_DESC from CO_PROD";
from("direct-vm:sqlRoute").routeId("testSQL")
.streamCaching()
.to(String.format("sql:%s?dataSource=sqlDataSource", GET_PRODUCTS_QUERY))
.log(LoggingLevel.INFO, "SQL response = ${body}");
蓝图.xml
<reference id="sqlDataSource" filter="(osgi.jndi.service.name=sqlDataSource)" interface="javax.sql.DataSource"/>
<bean id="sqlComponent" class="org.apache.camel.component.sql.SqlComponent">
<property name="dataSource" ref="sqlDataSource"/>
</bean>
当连接到 SQL 2008(这具有相同的表/数据)时,我从同一条路线收到以下错误:

如果我切换到下面的 jdbc 连接样式,它适用于 SQL Server 2008:
from("direct-vm:sqlRoute").routeId("testSQL")
.streamCaching()
.setBody(simple("select PRODUCT_ID,PRODUCT_DESC from CO_PROD",String.class))
.to("jdbc:sqldataSource")
.log(LoggingLevel.INFO, "SQL response = ${body}");
camel-sql 是否仅适用于某些版本的 SQL 服务器?
有没有办法记录在 .to 中发送的端点/连接信息?
谁能帮我理解为什么初始路由不适用于 SQL 2008,但连接到 SQL 2012 的同一路由可以正常工作?
