spring 引导中的请求参数和请求正文的通用验证

Question

如何为请求参数和请求正文编写或配置通用验证注释或 class 而不是一一验证

下面的示例我们在方法本身中一一验证。 而不是如何验证我们将用于所有方法和 class 的通用方法，而不是验证每个方法

    @PostMapping(value="/agreements/{agreement-number}/payments", produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<ResponseModel> initiatePayment(@Valid @RequestBody PaymentInitiateModel paymentInitiateModel,
            @RequestHeader(value = "orgCode", required = true) @Valid @NotNull(message = "Mandatory Field Missing") @Size(min = 3, max = 10, message = "Min/Max Length Validation Failed")  String orgCode,
            @RequestHeader(value = "apiName", required = true) @Valid @NotNull(message = "Mandatory Field Missing") @Size(min = 3, max = 20, message = "Min/Max Length Validation Failed")  String apiName,
            @RequestHeader(value = "uniqueRefNo", required = true) @Valid @NotNull(message = "Mandatory Field Missing") @Size(min = 3, max = 15, message = "Min/Max Length Validation Failed")  String uniqueRefNo,
            @RequestHeader(value = "requestTime", required = true) @ValidDate @NotNull(message = "Mandatory Field Missing") String requestTime,
            @RequestHeader(value = "status", required = true) @Valid @NotNull(message = "Mandatory Field Missing") @Size(min = 1, max = 10, message = "Min/Max Length Validation Failed")  String status,
            @RequestHeader(value = "remarks", required = true) @Valid @NotNull(message = "Mandatory Field Missing") @Size(min = 3, max = 10, message = "Min/Max Length Validation Failed")  String remarks,
            @PathVariable("agreement-number") String agreementNumber)
    {

您可以创建数据类并在这些类中提供验证约束。 它看起来像下面这样。

public class ExampleRequest {

    @NotBlank(message = "app.user.full.name.invalid")
    @Size(max = 128, message = "invalid.field.size.128")
    private String fullName;

    @NotBlank(message = "invalid.format.phone.number")
    @Size(min = 11, max = 11, message = "invalid.field.size.128")
    private String phoneNumber;

    @NotBlank(message = "app.user.mail.invalid")
    @Size(max = 128, message = "invalid.field.size.128")
    private String mail;

    @NotBlank(message = "app.user.password.invalid")
    @Size(max = 128, message = "invalid.field.size.128")
    private String password;

    @NotBlank(message = "app.user.password.confirm.invalid")
    @Size(min = 8, max = 32, message = "password.character.count.invalid")
    private String passwordConfirm;

    @NotNull(message = "app.user.role.names.null")
    private Set<String> roleNames;

    private Long companyId = -1L;

}

然后将它与@Valid注释一起使用，它会起作用。

public ResponseEntity<ResponseModel> exampleMethod(@RequestBody @Valid ExampleRequest exampleRequest) {
    // ...
}
