Question

我正在为http请求编写通用路由。端点不是静态值。路由代码：

from("direct:processRequests")
                .split(body().method("getItems"), new GroupedBodyAggregationStrategy())
                .parallelProcessing()
                .to("direct:processRequest")
       .end();


         from("direct:processRequest")
         .when(body().method("getHttpDetails").method("getCallType").isEqualTo("GET"))
            .setProperty("type",body().method("getInterfaceId"))//to identity response later
            .setHeader(Exchange.HTTP_METHOD, body().method("getHttpDetails").method("getCallType"))
            .setHeader(Exchange.CONTENT_TYPE, body().method("getHttpDetails").method("getPayLoadType"))
            .setHeader("Accept", body().method("getHttpDetails").method("getPayLoadType"))
            .to(body().method("getEndPointUri").toString())

这里我试图从body获取端点。但是到目前为止它失败了，例外：

我知道我们可以使用toD（）来获取动态端点。但是为此我们需要端点的某些部分存在于toD（）中。这里我试图动态加载整个端点。它有什么方法吗？< / p>

提前致谢。

Answer 1

configure类中的RouteBuilder方法仅在启动期间调用一次来设置路由。

因此，如果你想要任何动态uri，那么就像常见问题解答所说的那样使用toD http://camel.apache.org/how-to-use-a-dynamic-uri-in-to.html

在运行时期间在apche camel中获取端点
