java - 试图取回 JasperPrint 作为服务器的返回类型

Question

我有一个服务器端代码作为

    @POST
    @Path("/getJasperPrint")
    public  JasperPrint getReport(ReportMapper reportMapper,@Context HttpServletRequest request,@Context  HttpServletResponse response) throws Exception{
jasperPrint = JasperFillManager.fillReport(jasperReport, reportMap,
                        DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb" + "?user=" + "admin" + "&password=" + "admin"));
return jasperPrint ;
}

我正在尝试使用 RestTemplate 作为

  RestTemplate abc = new RestTemplate();
    JasperPrint jasperPrint = abc.postForObject("http://localhost:8008/report/getJasperPrint", objectA, JasperPrint.class);

报错

no suitable HttpMessageConverter found for response type [class path to jasperPrint].

我需要在这里做的任何事情。

Spring 源码博文

Objects passed to and returned from the methods getForObject(), postForLocation(), and put() and are converted to HTTP requests and from HTTP responses by HttpMessageConverters.

我认为您需要编写自己的转换器才能获得 jasperprint 的响应
