sql - camel-sql 问题（不同的 sql server 版本）

问题描述

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？

解决方案

引起：java.lang.ClassNotFoundException: org.antlr.v4.runtime.ANTLRErrorListener not found by com.microsoft.sqlserver.mssql-jdbc

也许您需要尝试另一个 jdbc 驱动程序，例如 SQL Server 2008 的 JDBC 驱动程序列表（比较）
