如何从json-schema验证器中的处理报告中提取所有消息？

Question

我使用json-schema验证器来验证json数据。如果发生任何错误，它将生成一个报告。但是我想向用户显示错误报告太大了，所以我只想显示错误消息。

这是我的报告

-报告

com.github.fge.jsonschema.report.ListProcessingReport:故障

我怎么才能只得到错误信息，任何建议都会有很大帮助。

Answer 1

您可以将报告作为JsonNode读取，并从中获取所需的任何参数。

ProcessingReport report;
ProcessingMessage message;

report = schema.validate(jsonData);
Iterator itr = report.iterator();

while(itr.hasNext())
{
    message = (ProcessingMessage) itr.next();
        System.out.println("Message" + message.asJson().get("message").asText());
 System.out.println("Reports" + message.asJson().get("reports").asText());

}

Answer 2

在比较getLogLevel()和LogLevel.ERROR时，您应该遍历所有的消息并选择

。

Iterator<ProcessingMessage> itr = report.iterator();
while(itr.hasNext())
{
    ProcessingMessage message = (ProcessingMessage) itr.next();
    if(message.getLogLevel().equals(LogLevel.ERROR)){
        System.out.println(message.toString());
    }
}

Answer 3

您可以使用以下方法

String getErrorsList(ProcessingReport report, boolean onlyErrors) {
    StringBuilder jsonValidationErrors = new StringBuilder();
    for (ProcessingMessage processingMessage : report) {
        if(onlyErrors && LogLevel.ERROR.equals(processingMessage.getLogLevel())) {
            jsonValidationErrors.append(processingMessage.getMessage()).append("\n\r");
        } else if(!onlyErrors) {
            jsonValidationErrors.append(processingMessage.getMessage()).append("\n\r");
        }
    }
    return jsonValidationErrors.toString();
}
