使用JiraRestClient（Java）创建Jira Issue时遇400错误求助

依赖配置 #

compile 'com.atlassian.jira:jira-rest-java-client-api:5.2.4'
compile 'com.atlassian.jira:jira-rest-java-client-core:5.2.4'

原创建Issue代码 #

@SneakyThrows
public BasicIssue createIssue(JiraIssueType jiraIssueType) {
    return jiraRestClient.getIssueClient().createIssue(
            IssueInput.createWithFields(
                    new FieldInput(IssueFieldId.PROJECT_FIELD, PROJECT_KEY),
                    new FieldInput(IssueFieldId.ISSUE_TYPE_FIELD, jiraIssueType.getValue()),
                    new FieldInput(IssueFieldId.SUMMARY_FIELD,
                            String.format("Add new dataset %s to object type %s", "toy",
                                    "story")),
                    new FieldInput(IssueFieldId.DESCRIPTION_FIELD, "descrption")
            )).fail(throwable -> log.error(throwable.getMessage()))
            .claim();
}

问题分析与解决方案 #

错误提示包含两个核心问题：

1. project字段验证失败：直接传递字符串无法被Jira正确解析为ResourceRef类型，Jira期望接收包含key或id的对象结构。
2. issuetype序列化失败：传入的数值类型无法直接实例化为ResourceRef，需要封装为ResourceRef对象。

修正后的代码如下：

@SneakyThrows
public BasicIssue createIssue(JiraIssueType jiraIssueType) {
    // 用ResourceRef封装project（使用project key）
    ResourceRef projectRef = new ResourceRef(null, PROJECT_KEY);
    // 用ResourceRef封装issuetype（假设jiraIssueType.getValue()是issue type的ID）
    ResourceRef issueTypeRef = new ResourceRef(jiraIssueType.getValue().toString(), null);

    return jiraRestClient.getIssueClient().createIssue(
            IssueInput.createWithFields(
                    new FieldInput(IssueFieldId.PROJECT_FIELD, projectRef),
                    new FieldInput(IssueFieldId.ISSUE_TYPE_FIELD, issueTypeRef),
                    new FieldInput(IssueFieldId.SUMMARY_FIELD,
                            String.format("Add new dataset %s to object type %s", "toy", "story")),
                    new FieldInput(IssueFieldId.DESCRIPTION_FIELD, "description")
            )).fail(throwable -> log.error(throwable.getMessage()))
            .claim();
}

关键修改点 #

• Project字段：ResourceRef第一个参数传ID（无需则填null），第二个参数传project key。
• IssueType字段：如果jiraIssueType.getValue()是issue type的ID，第一个参数传ID的字符串形式，第二个参数传null；如果是issue type的名称，交换两个参数位置即可。
