从骆驼交换到Java对象的迭代/获取数据

Question

在项目流中，我正在以Apache Camel Exchange中的JSON Collection的形式获取数据，并进一步处理它，我需要在Java对象中进行转换，

try{

        List<RespModel> records = (List<RespModel>) exchange.getIn().getBody(RespModel.class);

        System.out.println(records.size());

    }catch (Exception e){
        System.out.println("NO LUCK "+e.getLocalizedMessage());
    }

但我将记录视为null。 您能帮我改变吗？

交换数据如下 -

      "identifier": {
          "domain": "transport",
          "id": "123",
          "version": 1
      },
      "record": "NEW",
      "payload": {
          "pesonalDetails" : {
          "name" : "bla bla bla"
          "dob" : 
          },
          "reason" :
          
      }
},{
      "identifier": {
          "domain": "transport",
          "id": "123",
          "version": 1
      },
      "record": "NEW",
      "payload": {
          "pesonalDetails" : {
          "name" : "bla bla bla"
          "dob" : 
          },
          "reason" :
          
      }]```

I am getting null here, how can i achieve this ? pls reply if you know. Thanks

最终得到答案 -

String result = IOUtils.toString((InputStream) exchange.getIn().getBody(), StandardCharsets.UTF_8);
        List<RespModel> = new ObjectMapper().readValue(result,
                new TypeReference<List<RespModel>>() {
                });
