JDBC 从 Camel 和 Spring 启动到 MS SQL 服务器

Question

我正在尝试使用 Spring 引导从 Camel 访问 SQL 服务器，但我收到错误消息“com.bw.ReportRouter 中的字段数据源需要一个类型为 'org.springframework.jdbc.datasource.AbstractDataSource' 找不到。"

我正在使用一些教程来尝试解决这个问题，主要是这个：https://www.javainuse.com/camel/camel_jdbc

如果我理解正确，Spring 引导应该自动配置这个 bean。

这是我的路线。我只是想做一个简单的查询来建立连接：

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}");
    }

}

这里是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

我认为这没问题，但这是我的 pom。

没有其他东西可以展示。我从 Maven 原型生成项目：mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes -DarchetypeArtifactId=camel-archetype-spring-boot -DarchetypeVersion=3.11.1

这是唯一的另一篇，主要过程：

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);
        }
    
    }

Answer 1

这是一个工作示例。

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
