我正在尝试向控制器提交POST请求，但控制器没有响应我的请求，也没有抛出任何错误，但GET请求正常。
我正在使用
<button type="submit" class="btn btn-primary">Submit</button>
在控制器发送我的请求，这将是处理我的请求的控制器>>
@GetMapping("/flexfieldkeysegment/{keyFlexFieldSegmentId}")
public String editCategoryForm(@PathVariable Integer keyFlexFieldSegmentId, Model model) {
String tenantName=getCurrentTenant().getUser().getTenantName();
FlexFieldKeySegment segment = keySegment.findFlexFieldKeySegmentById(tenantName, keyFlexFieldSegmentId);
model.addAttribute("keySegment",segment);
return viewPrefix+"edit_flexfield_key_segment";
}

而不是@GetMapping，使用@PostMapping。另外，使用@RequestBody注释'Model'POJO
@PostMapping("/flexfieldkeysegment/{keyFlexFieldSegmentId}")
public String editCategoryForm(@PathVariable Integer keyFlexFieldSegmentId, @RequestBody Model model) {
String tenantName=getCurrentTenant().getUser().getTenantName();
FlexFieldKeySegment segment = keySegment.findFlexFieldKeySegmentById(tenantName, keyFlexFieldSegmentId);
model.addAttribute("keySegment",segment);
return viewPrefix+"edit_flexfield_key_segment";
}
