1. 确保在项目的POM文件中添加了MongoDB驱动：

org.mongodb mongo-java-driver 3.12.7

2. 确认MongoDB连接URI地址，确保其有效无误。示例：

mongodb://localhost:27017/testdb

3. 在Camel路由中指定MongoDB组件，并设置其相关属性，比如数据库名和集合名：

import org.apache.camel.builder.RouteBuilder;

public class MyRouteBuilder extends RouteBuilder {

@Override
public void configure() throws Exception {
    from("direct:saveToMongo")
        .to("mongodb:myDb?database=testdb&collection=myCollection");
}

}

4. 在CamelContext配置中注册MongoDB组件：

import org.apache.camel.component.mongodb.MongoDbComponent;

public class MyApp {

public static void main(String[] args) throws Exception {
    CamelContext context = new DefaultCamelContext();

    // Register the MongoDB component
    MongoDbComponent mongo = new MongoDbComponent();
    mongo.setMongoConnection("mongodb://localhost:27017");
    context.addComponent("mongodb", mongo);
    
    // Start the context and add the routes
    context.start();
    context.addRoutes(new MyRouteBuilder());
    Thread.sleep(10000);
    context.stop();
}

}

以上就是解决'Apache Camel route with MongoDB gives an error No bean could be found in the registry”问题的方法。
