使用RESTfull webservice（jersey）进行Javax验证？

Question

我目前正在进行一项服务，我必须使用服务验证。我们通过存储库在数据库中存储的请求类从客户端获取输入，我们必须提供注释和我们必须的位置给出bindingresult参数。当我们调用服务时，必须进行验证。在这里，我附上了示例代码。

这是我尝试实施验证的服务类

public long create(@Valid Document document,BindingResult bindingResult,DocumentResourceRequest DocumentResourceRequest,
        long agreementId) throws Exception {
    // TODO Auto-generated method stub
    logger.info("In DocumentServiceImpl createLoanDocument");

    Document documentObject = new Document(new lend(
            agreementId));

    documentObject.setDocumentType(DocumentResourceRequest
            .getDocumentType());
    documentObject.setDocumentDetails(DocumentResourceRequest
            .getDocumentDetails());
    documentObject.setRemarks(DocumentResourceRequest.getRemarks());
    documentObject.setDocumentStatus(DocumentResourceRequest
            .getDocumentStatus());
    documentObject.setCreatedBy(DocumentResourceRequest
            .getCreatedBy());
    documentObject.setCreatedOn(new Date());
    try {
        if(document != null)
        {
        document = loanDocumentRepo.saveAndFlush(documentObject);//DocumentRepository
        }else(bindingResult.getAllErrors())//if getting errors
        {

        }

    } catch (Exception e) {
        throw new Exception("Error in persisting Document-->" + e);
    }

    return document.getId();

}
