我刚开始用java编码，所以这个问题可能听起来很傻。

**目标：**我正在尝试构建一个Quarkus Rest应用程序，该应用程序具有使用Apache Camel路由的POST方法。目标是将水果数组作为输入，添加附加信息并将其返回给调用应用程序

• 通过POSTMAN传递到Quarkus应用程序http：//localhost：8080/simple的输入 *

[{
    "id": 1,
    "name": "one"
},{
    "id": 2,
    "name": "second"
}]

**问题：**每当我尝试通过HTTP客户端（POSTMAN）调用REST端点时，我都会收到错误。堆栈跟踪如下

有人能帮我找出我做错了什么吗？

这是我的路线代码：

package com.company;

import org.apache.camel.LoggingLevel;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.rest.RestBindingMode;
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import java.util.List;

@ApplicationScoped
public class RouteBuild extends RouteBuilder {

  Logger logger = LoggerFactory.getLogger(RouteBuild.class);

  @Override
  public void configure() throws Exception {

    restConfiguration().component("platform-http").bindingMode(RestBindingMode.auto);

    rest("/simple")
      .post()
      .type(FruitsList.class)
      .outType(AddressRequest.class)
      .route()
      .routeId("New Route")
      .log(LoggingLevel.INFO, "Passing input data to Direct Component for further actions")
      .to("direct:directDataEntry");

    from("direct:directDataEntry")
      .unmarshal().json()
      .log(LoggingLevel.INFO, "Inside the route to validate the data structure of the input")
      .log(LoggingLevel.INFO, "data of input is ${body}")
      .to("direct:directDataEntry1");

    from("direct:directDataEntry1")
      .routeId("validateData")
      //.log(LoggingLevel.INFO,"Passing input data to validate in route \"validationData\"")
      .process(new Processor() {
        @Override
        public void process(Exchange exchange) throws Exception {

          AddressRequest addressRequest = new AddressRequest();
          addressRequest.setCity("Atlanta");
          addressRequest.setInput_id("1");
          addressRequest.setState("GA");
          addressRequest.setStreet(exchange.getIn().getBody(FruitsList.class).getFruitsList().get(0).getName());
          exchange.getIn().setBody(addressRequest);
   }
      });

  }
}

下面是FruitsList、Fruits和AddressRequest类的代码（POJO）
Fruits.class

package com.company;

public class Fruits {

  public Fruits() {}
  private int id;
  private String name;

  public int getId() {
    return id;
  }

  public void setId(int id) {
    this.id = id;
  }

  public String getName() {
    return name;
  }

  public void setName(String name) {
    this.name = name;
  }
}

FruitsList.class

package com.company;

import java.util.List;

public class FruitsList {

    private List<Fruits> fruitsList;
    public FruitsList(){
    }
    public List<Fruits> getFruitsList() {
        return fruitsList;
    }
    public void setFruitsList(List<Fruits> fruitsList) {
        this.fruitsList = fruitsList;
    }
}
