camel-sql 2.22.1
В моем маршруте у меня есть:
from("direct:targetDatabase").startupOrder(1)
.process(new Processor() {
public void process(Exchange exchange) throws Exception {
System.out.println("BODY:"+exchange.getIn().getBody());
System.out.println(
exchange.getIn().
getBody(MessageContentsList.class).get(1));
}
})
С консоли я вижу:
BODY:[[{"id":2314,"code":"3498HK","value":30.88}], testInsert1]
testInsert1
Я хочу использовать этозначение, чтобы выбрать, какой SQL-оператор выполнить с помощью SQLComponent.
У меня есть файл sql.properties:
sql.insertdata=insert into gsdata values(:#id, :#code, :#value)
sql.testInsert1=insert into gsdata2 values(:#id, :#code, :#value)
На моем маршруте я знаю, что это работает:
.to("sqlComponent:{{sql.insertdata}}")
но я хочу сделать это (или как-то добиться этого):
.toD("sqlComponent:{{sql.${bodyAs(java.util.List).get(1)}}}")
, что дает мне исключение во время выполнения верблюда при развертывании в Tomcat.

Я пробовал много вариантов этого утверждения, но безуспешно.Есть три вопроса:
- Как динамически установить значение, которое sqlcomponent будет использовать для получения соответствующего sql?
- Как правильно извлечь значение из тела?
- Есть ли лучший способ сделать это?
Большое спасибо, и это лучший сайт за всю историю!
