java - Camel 路线创建错误，未找到方案 : mongodb 的组件

Question

我是 Apache camel 的新手，正在尝试编写一个路由，该路由应从指定路径上的文件中读取数据并将内容存储在 mongodb 中。好像我在指定 mongodb 路径时做错了什么，结果我在控制台上收到错误 ( Failed to create route route1 at: >>> To[mongodb:myDb?database=email_response&collection=emailResponse&operation=save] <<< in route: Route(route1)[[From[file:C://workspace//Emai... because of Failed to resolve endpoint: mongodb://myDb?collection=emailResponse&database=email_response&operation=save due to: No component found with scheme: mongodb )，请看一下。

控制台输出

Camel 路线

@Override
    public void configure() throws Exception {
        from("file:C://workspace//EmailResponseAutomation//response//")
        .to("mongodb:myDb?database=email_response&collection=emailResponse&operation=save");

为了将 Camel 与 MongoDB 一起使用，您需要 Camel MongoDB Component , 添加

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-mongodb</artifactId>
    <version>2.17.0</version>
</dependency>

到你的 pom。
