Question

我有一个json字符串

{
    "query": {
        "filtered": {
            "filter": {
                "bool": {
                    "must": [{
                        "terms": {
                            "task_id": ["000JAGUAR8M,000JAGUAR94,000JAG0009I,000JQQ0009O,000JAGUAR6Y,000JAGUAR7H,000JAGUAR7I,000JAKAAL7J,000BAKAAL7K,000JAGUAR7L"]
                        }
                    }]
                }
            }
        }
    },
    "size": 0,
    "aggs": {
        "task_ids": {
            "terms": {
                "field": "task_id",
                "size": 0
            }
        }
    }
}

我只需要替换task_id部分内部术语，以便每个任务都在双引号内。

{
    "query": {
        "filtered": {
            "filter": {
                "bool": {
                    "must": [{
                        "terms": {
                            "task_id": ["000JAGUAR8M","000JAGUAR94","000JAG0009I","000JQQ0009O","000JAGUAR6Y","000JAGUAR7H","000JAGUAR7I","000JAKAAL7J","000BAKAAL7K","000JAGUAR7L"]
                        }
                    }]
                }
            }
        }
    },
    "size": 0,
    "aggs": {
        "task_ids": {
            "terms": {
                "field": "task_id",
                "size": 0
            }
        }
    }
}

我可以使用下面的代码读取task_ids，但是如何在json对象中写回更改的值（requiredTasksIdValues）？

String str = "{\"query\":{\"filtered\":{\"filter\":{\"bool\":{\"must\":[{\"terms\":{\"task_id\":[\"000JAGUAR8M,000JAGUAR94,000JAG0009I,000JQQ0009O,000JAGUAR6Y,000JAGUAR7H,000JAGUAR7I,000JAKAAL7J,000BAKAAL7K,000JAGUAR7L\"]}}]}}}},\"size\":0,\"aggs\":{\"task_ids\":{\"terms\":{\"field\":\"task_id\",\"size\":0}}}}";
ObjectMapper mapper = new ObjectMapper();
try {
    JsonNode taskIdsjsonNode = mapper.readTree(str);
    JsonNode jn = taskIdsjsonNode.get("query").get("filtered").get("filter").get("bool").get("must").get(0).get("terms").get("task_id");
    StringBuffer temp = new StringBuffer(jn.toString().substring(2));
    temp = new StringBuffer(temp.substring(0, temp.length() - 2));
    String[] temp_task_ids = temp.toString().split(",");            
    StringBuffer requiredTasksIdValues = new StringBuffer();
    for (String taskid: temp_task_ids) {
        requiredTasksIdValues.append("\""+taskid+"\",");
    }
    requiredTasksIdValues = new StringBuffer(requiredTasksIdValues.substring(0, requiredTasksIdValues.length() - 1));
    System.out.println(requiredTasksIdValues);
} catch (JsonProcessingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

System.out.println(str);

String original = "000JAGUAR8M,000JAGUAR94,000JAG0009I,000JQQ0009O,000JAGUAR6Y,000JAGUAR7H,000JAGUAR7I,000JAKAAL7J,000BAKAAL7K,000JAGUAR7L";

String[] elements = original.split(",");

System.out.println(Arrays.toString(elements));

如何替换所有单词，使其在双引号内？
