尝试创建简单的REST服务并通过blueprint.xml文件应用路由。我想在没有Spring的情况下做到这一点...... - 只有蓝图

我的尝试都以以下例外结束：

.navi.uk-active .uk-panel-box {
  padding:0;
}

感到沮丧，因为我没有足够的“参考框架”来检测是否缺少关键组件，或版本问题等......

感谢任何帮助，找出错误/缺失等等。

以下是我正在使用的简单应用：

patterns for context mapping in the context of DDD (domain-driven design)

RestPostService.java 

"java.lang.IllegalStateException: Cannot find RestConsumerFactory in Registry or as a Component to use"

ThePojo.java 

package aaa.bbb.ccc;

import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.core.Response;
import javax.ws.rs.Produces;
import javax.ws.rs.Consumes;
import javax.ws.rs.core.MediaType;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

@Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
@Consumes({MediaType.APPLICATION_JSON,MediaType.APPLICATION_XML})
@Path("/service")
public class RestPostService {

    private static final Logger LOG = LogManager.getLogger("WebServiceSB");
    public RestPostService() {
    }

    @Path("/get1")     
    @GET
    public ThePojo get1() {
    ThePojo tp = new ThePojo("aaa", "bbb");
    return tp;
    }    

    @Path("/post1")        
    @POST
    @Produces(MediaType.TEXT_HTML)    
    public Response post1(ThePojo tp) {
    return Response.status(200).build(); 
    }
}

blueprint.xml 

package aaa.bbb.ccc;

public class ThePojo {

    public ThePojo() {
    }    

    private String field1;
    private String field2;

    public String getField1() {
    return field1;
    }
    public void setField1(String field1) {
    this.field1 = field1;
    }

    public String getField2() {
    return field2;
    }
    public void setField2(String field2) {
    this.field2 = field2;
    }

    public ThePojo(String field1, String field2) {
    this.field1 = field1;
    this.field2 = field2;
    }

    @Override
    public String toString() {
    return "ThePojo{" + "field1=" + field1 + ", field2=" + field2 + '}';
    }
}

FWIW - 试图从位于以下位置的现有示例中获取此POC：

但是，显然，这个例子已经3年多了......： - （

1 个答案:

答案 0 :(得分：0)

您不能将CXF与rest-dsl一起使用，您需要使用其中一个受支持的组件：http://camel.apache.org/rest-dsl

然后您需要通过以下方式从ServiceMix shell安装：<{1}}等。

请参阅Apache Camel的一些REST示例：https://github.com/apache/camel/tree/master/examples#examples
