小编Luk*_*ker的帖子

我已经尝试了许多使用orderBy进行ng-repeat的例子,但我不能让我的json使用它.

<div ng-app>
    <script type="text/javascript" src="http://code.angularjs.org/1.0.1/angular-1.0.1.js"></script>
    <div ng:controller="Main">
        <div ng-repeat="release in releases| orderBy:'environment_id'">      
            {{release.environment_id}}
        </div>
    </div>
</div>

还有JSON

function Main($scope) {
$scope.releases = {
    "tvl-c-wbap001 + tvl-webapp": {
        "timestamp": " 05:05:53 PM ",
        "environment_id": "CERT5",
        "release_header": "Projects/Dev",
        "date": "19 Oct",
        "release": "12.11.91-1"
    },
    "tvl-c-wbap401 + tvl-webapp": {
        "timestamp": " 10:07:25 AM ",
        "environment_id": "CERT4",
        "release_header": "Future Release",
        "date": "15 Oct",
        "release": "485-1"
    },
    "tvl-c-wbap301 + tvl-webapp": {
        "timestamp": " 07:59:48 AM ",
        "environment_id": "CERT3",
        "release_header": "Next Release",
        "date": "15 Oct", …

我看着之间的差异poll，epoll和select。我不知道是什么时候应该使用select。鉴于此poll，我看不到任何优势，并且epoll拥有一切，select还有更多。

每次我用maven编译时都会遇到以下异常.

我仅因一项服务而遇到此异常。我的控制器中有两项服务，另一项工作正常。

@Controller\n@RequestMapping("/document")\npublic class DocumentController {\n\n@Autowired\nprivate PdfService pdfService;\n\n@Autowired\nprivate MailService mailService;\n\n@Autowired\nprivate TransaccionService transaccionService;\n\n@Autowired\nprivate UsuarioService usuarioService;\n\n@RequestMapping(value = "/export", method = RequestMethod.GET)\npublic void exportAutorizacion(HttpServletRequest request){\n    TicketAutorizacionDto ticket = (TicketAutorizacionDto) request.getSession().getAttribute("ticketAutorizacion");\n    this.pdfService.createPdf(ticket);\n\n}\n\n@RequestMapping(value = "/email/{numeroAutorizacion}", method = RequestMethod.PUT)\npublic Boolean enviarMail(@PathVariable("numeroAutorizacion") Integer numeroAutorizacion,@ModelAttribute EmailsForm mails){\n\n    if(mails.getEmails().isEmpty() || numeroAutorizacion == null){\n        return false;\n    }\n\n    UsuarioForm usuarioForm = null;\n    Authentication auth = SecurityContextHolder.getContext().getAuthentication();\n    try {\n        usuarioForm = this.usuarioService.getUsuarioByNombreUsuario(auth.getName());\n        TicketAutorizacionDto ticket = this.transaccionService.getTicketAutorizacion(numeroAutorizacion, usuarioForm.getIdBeneficiario());\n        return this.mailService.enviarOrdenMedica(ticket, mails.getEmails().toArray(new String[mails.getEmails().size()]));\n    } catch (NoExisteBeneficiarioException e) {\n        e.printStackTrace();\n    }\n\n    return false;\n    }\n}\n
