Question

我对骆驼完全陌生。我正在尝试按照一个简单的示例说明如何使用休息服务。

UPDATE D SET
    Quantity = S.Quantity
FROM
    Staging AS S
    INNER JOIN VendorMaster AS V ON S.Vendor = V.Vendor -- Fetch the VendorID from VendorMaster
    INNER JOIN Data AS D ON
        V.VendorID = D.VendorID AND
        S.ProductName = D.ProductName
WHERE
    S.Quantity <> D.Quantity -- Update only if there are differences

INSERT INTO Data (
    VendorID,
    ProductName,
    Quantity)
SELECT
    VendorID = V.VendorID,
    ProductName = S.ProductName,
    Quantity = S.Quantity
FROM
    Staging AS S
    INNER JOIN VendorMaster AS V ON S.Vendor = V.Vendor -- Fetch the VendorID from VendorMaster
WHERE
    NOT EXISTS (
        SELECT
            'data not yet loaded'
        FROM
            Data AS D
        WHERE
            V.VendorID = D.VendorID AND
            S.ProductName = D.ProductName)

运行此测试时，我得到

public class RestRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {

        getContext().getProperties().put("http.proxyHost", "myproxy");
        getContext().getProperties().put("http.proxyPort","8080");

        from("direct:restCall")
        .to("log:DEBUG?showBody=true&showHeaders=true")

        .setHeader(Exchange.HTTP_METHOD, constant("GET"))
        .setHeader(Exchange.HTTP_BASE_URI, simple("http://restcountries.eu/rest/v2/alpha/${body}"))
        .to("http://restcountries.eu/rest/v2/alpha/${body}")
        .to("log:?level=INFO&showBody=true");

    }
}

public class RestRouteTest extends CamelTestSupport {

    @Override
    public RouteBuilder createRouteBuilder() {
        return new RestRoute();
    }

    @Test
    public void test() {
        String response =   template.requestBody("direct:restCall","USA",String.class);
        System.out.println("response : " + response);
        assertNotNull(response);
    }

}

似乎无法用期望的String代替$ {body}。当我将参数“ USA”硬编码到URL中时，请求将按预期工作。任何想法我的错误可能是什么？谢谢。

使用toD进行动态

 .toD("http://restcountries.eu/rest/v2/alpha/${body}")

骆驼http在网址中使用$ {body}
