骆驼http组件500

Question

我正在创建 cxf/camel 网络服务，我已经为这样的测试代码创建了：

@GET
@Path("/user")
@ProduceMime({ "application/json" })
public String user(@FormParam("token") String token) throws Exception {

        CamelContext context = new DefaultCamelContext();

        context.addRoutes(new RouteBuilder() {
            public void configure(){
                from("direct:start").to("http://google.com");
            }
        });

        context.start();

        return token;

    }

}

然后我编译并复制了 FUSE ESB 部署文件夹。我的网络服务已安装，但是当我用我的网络服务打开 URL 时，我得到 500 响应：

  org.apache.cxf.interceptor.Fault: Failed to create route route17 at: >>> To[http://google.com] <<< in route: Route[[From[direct:start]] -> [To[http://google.com]]] because of Failed to resolve endpoint: http://google.com due to: No component found with scheme: http

另外我已经导入了：

import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.component.http.*;
import org.apache.camel.component.http.helper.*;

在 ESB 上我打开了 camel-http

怎么了？

所以我写的是错误的，下面的代码应该可以正常工作吗？

Answer 1

您需要安装 camel-http 功能。在 Fuse ESB 控制台中，您可以键入：

features:install camel-http

然后你可以安装/启动你的包。

正如 Ben 所说，你在 rest 服务中所做的事情是完全错误的。您应该设置一次骆驼路线。如果要使用 Camel 从 Java 代码调用 http 端点，则不需要路由，但可以使用 ProducerTemplate。有关详细信息，请参阅 Camel 文档。

Answer 2

有几件事，“没有找到带有方案的组件：http”意味着您在捆绑包中缺少骆驼-http 依赖项

接下来，您应该设置一次 Camel 上下文/路由……而不是像这样的方法调用。
