現在我要做的是遍歷 JSON 數據並將其存儲到 HashMap 中，其中鍵是“indeni_version”（例如 0.0.0.develop，它可能是 7.0.2.3 或任何其他版本）。 這是我對 HashMap 的實現 -> private static HashMap<String, List<ReportGenreratorFields>> reportGeneratorMapper = new HashMap<>();

其中ReportGeneratorFields類如下所示：

package com.indeni.automation;

public class ReportGenreratorFields {

    private String testname;
    private String jenkinsBuildNumber;
    private String jiraLinkedIssue;

    public String getTestname() {
        return testname;
    }

    public String getJenkinsBuildNumber() {
        return jenkinsBuildNumber;
    }

    public String getJiraLinkedIssue() {
        return jiraLinkedIssue;
    }

    public void setTestname(String testname) {
        this.testname = testname;
    }

    public void setJenkinsBuildNumber(String jenkinsBuildNumber) {
        this.jenkinsBuildNumber = jenkinsBuildNumber;
    }

    public void setJiraLinkedIssue(String jiraLinkedIssue) {
        this.jiraLinkedIssue = jiraLinkedIssue;
    }


}

並且它將包含 HashMap 的值，現在當我動態填充 hashmap 時，我注意到我確實填充了 JSON 數據中存在的確切數量的鍵，但是每次遇到已經插入的“indeni_version”時我都會覆蓋該值到我的哈希映射中，這不好，因為我想將值添加到已經存在的鍵中。

這是我嘗試過的：

public class ReportGenerator {

    private static HashMap<String, List<ReportGenreratorFields>> reportGeneratorMapper = new HashMap<>();
    private static ReportGenreratorFields reportGenreratorFields = new ReportGenreratorFields();
    private static List<ReportGenreratorFields> reportGeneratorFieldsList;

    public static void main(String[] args) throws Exception {
        try (ElasticSearchClient client = new ElasticSearchClient()) {
            SearchResponse sr = client.dailyReport();
            SearchHit[] results = sr.getHits().getHits();
            for (SearchHit hit : results) {
                reportGeneratorFieldsList = new ArrayList<>();
                reportGenreratorFields.setTestname(source.get("test_name").toString());
                reportGenreratorFields.setJenkinsBuildNumber(source.get("job_build_number").toString());
                if (source.get("link_issue") != null) {
                    reportGenreratorFields.setJiraLinkedIssue(source.get("link_issue").toString());
                } else {
                    reportGenreratorFields.setJiraLinkedIssue("new_bug");
                }
                reportGeneratorFieldsList.add(reportGenreratorFields);
                reportGeneratorMapper.put(source.get("indeni_version").toString(), reportGeneratorFieldsList);
            }catch(IOException e){
                LOG.error("failed to fetch documents from elastic search cluster", e);
            }
        }
    }

我忘了提到從這一行獲取 json 數據： SearchResponse sr = client.dailyReport(); 而hit只是來自 json 數據的一個項目。

使用這個更新的代碼：

public class ReportGenerator {

private static HashMap<String, List<ReportGenreratorFields>> reportGeneratorMapper = new HashMap<>();

public static void main(String[] args) throws Exception {
    try (ElasticSearchClient client = new ElasticSearchClient()) {
        SearchResponse sr = client.dailyReport();
        SearchHit[] results = sr.getHits().getHits();

        for (SearchHit hit : results) {
            ReportGenreratorFields reportGenreratorFields = new ReportGenreratorFields();
            reportGenreratorFields.setTestname(source.get("test_name").toString());
            reportGenreratorFields.setJenkinsBuildNumber(source.get("job_build_number").toString());
            if (source.get("link_issue") != null) {
                reportGenreratorFields.setJiraLinkedIssue(source.get("link_issue").toString());
            } else {
                reportGenreratorFields.setJiraLinkedIssue("new_bug");
            }
            String indeniVer = source.get("indeni_version").toString();
            //map contains that indeniVer then add to existing list
            if (reportGeneratorMapper.containsKey(indeniVer)) {
                List<ReportGenreratorFields> reportGeneratorFieldsList = reportGeneratorMapper.get(indeniVer);
                reportGeneratorFieldsList.add(reportGenreratorFields);
                reportGeneratorMapper.put(indeniVer, reportGeneratorFieldsList);
            } else { //map does not contain that indeniVer
                List<ReportGenreratorFields> reportGeneratorFieldsList = new ArrayList<>();
                reportGeneratorFieldsList.add(reportGenreratorFields);
                reportGeneratorMapper.put(indeniVer, reportGeneratorFieldsList);
            }
        }
    } catch (IOException e) {
        LOG.error("failed to fetch documents from elastic search cluster", e);
    }
  }
}

修復這一行：

reportGeneratorMapper.put(source.get("indeni_version").toString(), reportGeneratorFieldsList);

到：

List<ReportGenreratorFields> existingList = reportGeneratorMapper.get(source.get("indeni_version").toString());
if (existingList == null)
    reportGeneratorMapper.put(source.get("indeni_version").toString(), reportGeneratorFieldsList);
else{
        existingList.add(reportGenreratorFields);    
        reportGeneratorMapper.put(source.get("indeni_version").toString(),
    existingList);
}

您的代碼不檢查沖突。 它盲目地將新列表與密鑰相關聯。 在上面的代碼中，您首先檢查是否有一個列表已經與鍵相關聯。 如果沒有，則創建一個列表並將其與密鑰（您已經編寫的代碼）相關聯。 如果有，你得到它，將你的對象添加到它並再次將它分配給你的鍵。
