Java 未找到具有以下方案的组件：mongodb

我有这样的代码：

@Autowired
private ProducerTemplate producerTemplate;  
...   
final List<Map<String, Object>> parsedLines = ...
parsedLines.forEach(parsedLine -> {
    try {
        producerTemplate.sendBody("mongodb:mongoBean?database=db_name&collection=collection_name&operation=save", parsedLine);
    } catch (Exception e) {
        logger.error("error:", e);
    }
});

compile 'org.apache.camel:camel-mongodb-starter'

我也有依赖性：

compile 'org.springframework.boot:spring-boot-starter-data-mongodb'

它生成跟踪：

我做错了什么？如何纠正

附笔。 此外，应用程序还打印到日志：

作为依赖项，您真正需要的是

camel mongodb starter

，如下所示：

@Autowired
private ProducerTemplate producerTemplate;  
...   
final List<Map<String, Object>> parsedLines = ...
parsedLines.forEach(parsedLine -> {
    try {
        producerTemplate.sendBody("mongodb:mongoBean?database=db_name&collection=collection_name&operation=save", parsedLine);
    } catch (Exception e) {
        logger.error("error:", e);
    }
});

compile 'org.apache.camel:camel-mongodb-starter'

您需要将camel mongodb作为依赖项添加到您的项目中（例如，您始终需要为您正在使用的camel组件添加依赖项）
