解决：org.springframework.web.client.HttpClientErrorException: 405 null at org.springframework.web.clie

org.springframework.web.client.HttpClientErrorException: 405 null at org.springframework.web.client

排查了下原因
造成错误的原因：controller层请求 是标识 RequestMethod.POST的请求

@RequestMapping(value = "/downloadFile", method = RequestMethod.POST)
    public void downloadFile(HttpServletRequest request, HttpServletResponse response,
                             @RequestParam(value = "service_name", required = false) String serviceName,
                             @RequestParam("operator_code") String operatorCode)
            throws UnsupportedEncodingException {

然而在执行：内部发起请求的时候

            ResponseEntity<String> res = restTemplate.postForEntity(fileTransferBO.getFlmServerAddress(), ExcelUtils.createFileHttpParam(fileTransferBO), String.class);

请求所调用的接口方式是：method = RequestMethod.GET

@RequestMapping(value = "/getFileInfo", method = RequestMethod.GET)
    @ResponseBody
    public ApiResult getFileInfo(@RequestBody() FileTransferBO fileTransferBO) {

所以报这个错误。
解决：
这里把内部所调用的请求方式和controller层的调成一致即可解决该问题。

@RequestMapping(value = "/getFileInfo", method = RequestMethod.POST)
    @ResponseBody
    public ApiResult getFileInfo(@RequestBody() FileTransferBO fileTransferBO) {
