我正在尝试建立一个非常简单的方法来测试camel-olingo2组件。 在启动过程中，我可以验证我的Olingo2Component是否已使用正确的serviceUri填充，并且还添加到camelContext中。 目前，我正在针对公共OData测试站点进行测试，并且可以验证数据是否存在
以下是将Olingo成分添加到骆驼中的方法
@Bean
public Olingo2Component olingo2Component() {
Olingo2Configuration olingo2Configuration = new Olingo2Configuration();
olingo2Configuration.setServiceUri("https://services.odata.org/TripPinRESTierService");
Olingo2Component olingo2Component = new Olingo2Component();
olingo2Component.setConfiguration(olingo2Configuration);
CamelContext camelContext = new DefaultCamelContext();
camelContext.addComponent("olingo2", olingo2Component);
return olingo2Component;
}
我的路线看起来像这样
<routes xmlns="http://camel.apache.org/schema/spring">
<route id="test" autoStartup="true">
<from uri="olingo2Component://read/People"/>
<log message="${body}" />
</route>
</routes>
我不知道真正缺少哪些属性。由于没有添加查询，我希望收到一个包含People的OData条目的json
任何帮助或提示将不胜感激

答案 0 :(得分：0)
我注意到应该自动添加edm（实体数据模型）属性。 camel-olingo最初使用$ metadata进行了调用以查找得到edm。其他属性也应该自动添加。当您将初始端点作为olingo端点时，这似乎不起作用。尽管文档说是这样。
您可以尝试
<routes xmlns="http://camel.apache.org/schema/spring">
<route id="test" autoStartup="true">
<from uri="timer://olingo.test?repeatCount=1&delay=-1"/>
<to uri="olingo2Component://read/People"/>
<log message="${body}" />
</route>
</routes>
这将为您提供“内部服务器错误”异常，因为https://services.odata.org/TripPinRESTierService使用odata v4。
更改为camel-olingo4组件以使其返回数据。
