Java 在JSON上获取反斜杠

您应该具有以下 struct .我使用Jackson来处理反序列化/序列化，使用Lombok来处理POJO字段的getters/setters/toString.

正如其他人提到的，datapoints的类型应该是String到Double之间的Map.

import java.util.Arrays;
import java.util.Map;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.Data;

public class ParseJson {
    private static final String SAMPLE_JSON_DATA = "[{\"id\":\"346id71\",\"arg\":{\"test1\":\"pass\",\"task\":\"true\",\"direction\":\"right\"},\"datapoints\":{\"1680012000\":0.10124447461480172,\"1680048000\":8.398348387776654,\"1680084000\":8.338508371876594,\"1680120000\":8.357523374646366}},{\"id\":\"346id72\",\"arg\":{\"test1\":\"pass\",\"task\":\"true\",\"direction\":\"left\"},\"datapoints\":{\"1680012000\":0.123233,\"1680048000\":3.567384,\"1680084000\":4.47653,\"1680120000\":0,\"1680156000\":0}}]";

    private static ObjectMapper mapper = new ObjectMapper();

    public static void main(String[] args) throws JsonMappingException, JsonProcessingException {
        Response[] response = mapper.readValue(SAMPLE_JSON_DATA, Response[].class);
        System.out.println("\nOUTPUT :- Object::toString");
        System.out.println(Arrays.toString(response));
        System.out.println("\nOUTPUT :- ObjectMapper::writeValueAsString");
        System.out.println(mapper.writerWithDefaultPrettyPrinter().writeValueAsString(response));
    }

    @Data
    private static class Arg {
        String test1, task, direction;
    }

    @Data
    private static class Response {
        private String id;
        private Arg arg;
        private Map<String, Double> datapoints;
    }
}

输出

以下是.toString()电话:

[
  ParseJson.Response(
    id=346id71,
    arg=ParseJson.Arg(test1=pass, task=true, direction=right),
    datapoints={
      1680012000=0.10124447461480172,
      1680048000=8.398348387776654,
      1680084000=8.338508371876594,
      1680120000=8.357523374646366}
  ),
  ParseJson.Response(
    id=346id72,
    arg=ParseJson.Arg(test1=pass, task=true, direction=left),
    datapoints={
      1680012000=0.123233,
      1680048000=3.567384,
      1680084000=4.47653,
      1680120000=0.0,
      1680156000=0.0}
  )
]

还有.writerWithDefaultPrettyPrinter().writeValueAsString()电话:

[ {
  "id" : "346id71",
  "arg" : {
    "test1" : "pass",
    "task" : "true",
    "direction" : "right"
  },
  "datapoints" : {
    "1680012000" : 0.10124447461480172,
    "1680048000" : 8.398348387776654,
    "1680084000" : 8.338508371876594,
    "1680120000" : 8.357523374646366
  }
}, {
  "id" : "346id72",
  "arg" : {
    "test1" : "pass",
    "task" : "true",
    "direction" : "left"
  },
  "datapoints" : {
    "1680012000" : 0.123233,
    "1680048000" : 3.567384,
    "1680084000" : 4.47653,
    "1680120000" : 0.0,
    "1680156000" : 0.0
  }
} ]
