ServletException：没有适用于一项服务的处理程序的适配器

Question

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。

\n\n

@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

有任何想法吗？

\n\n

谢谢！

编辑：这是抛出异常的完整堆栈。

Answer 1

为什么要尝试从控制器方法返回布尔值？该方法是否服务休息请求？在这种情况下，需要使用 @ResponseBody 进行注释，或者如果您使用的是 Spring 4.x，请将 @Controller 更改为 @RestController。如果这不是休息服务，我认为您无法返回布尔值。您必须返回 String 或 ModelAndView 对象。
