JDBC from Camel and Spring Boot to MS SQL Server - sql-server

Question

I'm trying to access SQL Server from Camel with Spring Boot, but I'm getting the error "Field dataSource in com.bw.ReportRouter required a bean of type 'org.springframework.jdbc.datasource.AbstractDataSource' that could not be found."
I'm using a few tutorials to try to figure this out, mainly this one: https://www.javainuse.com/camel/camel_jdbc
If I understand this correctly, Spring Boot should configure this bean automatically.
Here is my route. I'm just trying to make a simple query to establish the connection:
package com.bw;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.datasource.AbstractDataSource;
import org.springframework.stereotype.Component;
import javax.sql.DataSource;
#Component
public class ReportRouter extends RouteBuilder {
#Autowired
AbstractDataSource dataSource;
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(AbstractDataSource dataSource) {
this.dataSource = dataSource;
}
#Override
public void configure() {
from("timer:myTimer?repeatCount=1")
.setBody(simple("select top 10 * from eai.Audit_General"))
.log("SQL: ${body}")
.to("jdbc:dataSource")
.log("Out: ${body}");
}
}
Here is application.properties
#spring.datasource.url=jdbc:sqlserver://sqlsrv\\sqlexpress;databaseName=customer
spring.datasource.url=jdbc:sqlserver://my-server.database.windows.net;databaseName=my-db
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.initialization-mode=always
I think this is OK, but here is my pom.

There isn't much else to show. I generated the project from a Maven archetype: mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes -DarchetypeArtifactId=camel-archetype-spring-boot -DarchetypeVersion=3.11.1
Here is the only other piece, the main process:
package com.bw;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class MySpringBootApplication {
/**
* A main method to start this application.
*/
public static void main(String[] args) {
SpringApplication.run(MySpringBootApplication.class, args);
}
}

Here is a working example.
package com.bw;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.datasource.AbstractDataSource;
import org.springframework.stereotype.Component;
import javax.sql.DataSource;
#Component
public class ReportRouter extends RouteBuilder {
#Autowired
DataSource dataSource;
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(AbstractDataSource dataSource) {
this.dataSource = dataSource;
}
#Override
public void configure() {
from("timer:myTimer?repeatCount=1")
.setBody(simple("select top 10 * from eai.Audit_General"))
.log("SQL: ${body}")
.to("jdbc:dataSource")
.log("Out: ${body}");
}
}
application.properties
spring.datasource.url=jdbc:sqlserver://my-server.database.windows.net;databaseName=my-db
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
