我有以下 Dto 类结构
public class MyDto {
@Email
private String mail;
public String getMail() {
return mail;
}
public void setMail(String mail) {
this.mail = mail;
}
}
@Generated(value = "org.openapitools.codegen.languages.SpringCodegen", date = "2023-11-01T17:12:49.075897700+03:00[Europe/Moscow]")
public class CustomUserPatchRequestDto {
@JsonProperty("myDto")
@Valid
private JsonNullable<@Valid MyDto> myDto;
// getter and setter
...
以及以下控制器
@RestController
@Validated
class MyController() {
@RequestMapping(
method = [PATCH],
value = ["/userscustom/{id}"],
produces = ["application/json"],
consumes = ["application/merge-patch+json"]
)
fun patchUserCustom(
@Parameter(name = "id", description = "", required = true,in= PATH) @PathVariable("id") id: String?
@Valid @RequestBody userPatchRequestDto: CustomUserPatchRequestDto?
): ResponseEntity<String?>? {
return ResponseEntity.ok("ok")
}
当我发送带有正文的请求时
{
"myDto": {
"mail": "12sdfdsf3"
}
}
我收到错误响应：
{
"code": 500,
"reason": "JSR-303 validated property 'myDto.mail' does not have a corresponding accessor for Spring data binding - check your DataBinder's configuration (bean property versus direct field access)"
}
我该如何修复它？
我尝试在各处添加
@Valid尝试在控制器中添加InitBinder：
@InitBinder
private fun activateDirectFieldAccess(dataBinder: DataBinder) {
println("Working Inner")
dataBinder.initDirectFieldAccess();
}
还尝试添加单独的类：
@ControllerAdvice
class CustomControllerAdvice {
@InitBinder
private fun activateDirectFieldAccess(dataBinder: DataBinder) {
println("Working Inner")
dataBinder.initDirectFieldAccess();
}
}
在这两种情况下我都会看到消息
Working Inner
在控制台中。所以这段代码就被执行了。
但不幸的是我仍然有同样的问题。
附注
堆栈跟踪是：

非常奇怪的是，如果我传递正确的电子邮件，那么我就看不到任何错误，一切都正常。因此，仅当我传递无效电子邮件并在异常文本和类型中发出问题时，才会出现问题
