Question

我正在使用Apache Camel为MongoDB尝试一个示例。

我做的是这样的：我有我的主要方法：

public static void main(String[] args) {
         ApplicationContext context = new ClassPathXmlApplicationContext("camel-context-mongo.xml");
     }

我的camel-context-mongo.xml为：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:camel="http://camel.apache.org/schema/spring" 
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">
<camel:camelContext id="camel-client">
<camel:routeBuilder ref="vinodroute" />
</camel:camelContext>

<bean id="myDb" class="com.mongodb.Mongo">
<constructor-arg index="0" value="localhost" />
</bean>
<bean id="vinodroute" class="com.camel.test.CamelMongoRoute" />
</beans>

我的骆驼路线是

public void configure() throws Exception {
        from("jetty:http://localhost:8181/data")
        .to("mongodb:myDb?database=DataDB&collection=data&operation=findAll");
        from("jetty:http://localhost:8181/dataInsert")
        .to("mongodb:myDb?database=DataDB&collection=data&operation=insert");
                }

现在我正在尝试插入操作，即我试图通过soapUI调用http://localhost:8181/dataInsert休息服务，我的json有效负载是：

[{
    "DataID": "19dd8a2e-45cb-40cc-ba2c-15d5a81733f8",
    "DataDescription": "Data High",
    "DataPriority": "High"
  },
  {
    "DataID": "cfc6f177-fe18-419e-84cd-db11617f12af",
    "DataDescription": "Data Low Low",
    "DataPriority": "Low"
  },
  {
    "DataID": "822accd4-061f-491b-a417-1c683d0c268f",
    "DataDescription": "Data High",
    "DataPriority": "High"
  },
  {
    "DataID": "1c7dcf89-629c-4523-96c4-a2cc740d1769",
    "DataDescription": "Data High",
    "DataPriority": "High"
  },
  {
    "DataID": "1c0b5e66-3ca4-4a0a-a9a5-8d1397589ee9",
    "DataDescription": "Data Low",
    "DataPriority": "Low"
  },
  {
    "DataID": "05677b88-d43b-4224-be7e-66360a2f35a8",
    "DataDescription": "Data High",
    "DataPriority": "High"
  }]

现在上面的json是一个有效的json。但我仍然得到这个例外：

<data contentType="text/plain;charset=ISO-8859-1" contentLength="3128"><![CDATA[org.apache.camel.component.mongodb.CamelMongoDbException: MongoDB operation = insert, Body is not conversible to type DBObject nor List<DBObject>

我做错了什么？期待您的解决方案。提前谢谢。

Answer 1

尝试使用jackon将您的消息解组到列表中。 MongoDB组件知道如何创建DBObject，但不知道如何创建DBObject，您必须首先提供可转换为List的内容。

from("jetty:http://localhost:8181/data")
  .unmarshall(new ListJacksonDataFormat())
  .to("mongodb:myDb?database=DataDB&collection=data&operation=findAll");

Answer 2

from("")
    .marshal().json(JsonLibrary.Jackson)
    .unmarshal(new ListJacksonDataFormat())
    .to("mongodb:mongoClient?database=mytest&collection=testc&operation=insert")

这对我有用

Apache camel Body不能转换为DBObject类型，也不能转换为List <dbobject>
