Quarkus Jackson InvalidDefinitionException 找不到類型 [簡單類型，class java.math] 的（映射）密鑰解串器。

Question

我嘗試使用 Quarkus 開發 Rest API 以僅從來自 POST 有效負載的數據生成 PDF。 只有當應用程序在本機模式下運行時，我才會出現以下異常：

我的數據如下所示：

@Getter
@Setter
public class Invoice {

    @NotBlank
    private String number;

    @NotNull
    private LocalDate date;

    @NotNull
    private Currency currency;

    @NotNull
    @AllowedLocale
    private Locale locale;

    @NotNull
    @Valid
    private Provider provider;

    @NotNull
    @Valid
    private Customer customer;

    @NotNull
    @Valid
    private Order order;

    @Valid
    private ConsolidatedTaxes consolidatedTaxes;

    @NotNull
    @Valid
    private PaymentInstructions paymentInstructions;

}

一些嵌入對象具有 Map 和 BigDecimal Key：

@Getter
@Setter
public class ConsolidatedTaxes {

    @NotNull
    @Size(min = 1)
    @Valid
    private Map<BigDecimal, ValueAddedTax> byAmount;

    @NotNull
    @Valid
    private ValueAddedTax total;

}

還有一些直接使用 BigDecimal：

@Getter
@Setter
public class ValueAddedTax {

    @NotNull
    private BigDecimal baseAmount;

    @NotNull
    private BigDecimal taxAmount;

    @NotNull
    private BigDecimal includingTaxAmount;

}

我的依賴：

    <quarkus.version>1.3.2.Final</quarkus.version>
    <lombok.version>1.18.12</lombok.version>

我真的不明白 object 有什么問題需要反序列化。 在開發模式下運行時不會出現問題 append。

我如何進行反序列化：

<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-resteasy</artifactId>
</dependency>
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-resteasy-jackson</artifactId>
</dependency>
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-hibernate-validator</artifactId>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-multipart-provider</artifactId>
</dependency>

@Path("/v1/invoices")
public class InvoiceController {

    private InvoiceService invoiceService;

    InvoiceController(InvoiceService invoiceService) {
        this.invoiceService = invoiceService;
    }

    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces("application/pdf")
    public Response post(@MultipartForm InvoiceResource invoiceMultipartBody) throws IOException {
        if (Objects.nonNull(invoiceMultipartBody.getLogo())) {
            byte[] logo = invoiceMultipartBody.getLogo().readAllBytes();
            invoiceMultipartBody.getInvoice().getProvider().setLogo(logo);
        }

        Response.ResponseBuilder response = Response.ok(invoiceService.generate(invoiceMultipartBody.getInvoice()));
        response.header("Content-Disposition", "attachment; filename=" + invoiceMultipartBody.getInvoice().getNumber() + ".pdf");
        return response.build();
    }

}

@Getter
@Setter
public class InvoiceResource {

    @FormParam("logo")
    @PartType(MediaType.APPLICATION_OCTET_STREAM)
    public InputStream logo;

    @FormParam("invoice")
    @PartType(MediaType.APPLICATION_JSON)
    public Invoice invoice;

}

JSON 有效載荷示例：

{
    "number": "#Invoice-Number",
    "date": "2019-06-25",
    "currency": "EUR",
    "locale": "fr_FR",

    "provider": {
        "corporateName": "corporateName",
        "address": {
            "identification": "identificationAddressSender"
        }
    },

    "customer": {
        "address": {
            "identification": "identificationAddressRecipient"
        }
    },

    "order" : {
    "description": "description with accents special caracters &é'(§è!çà)-\""
    },

    "paymentInstructions": {
        "amount": 1386.26,
      "dueDate": "2019-07-25"
    }
}

什么是 append 只有在本機編譯期間才能產生這種行為？ 謝謝您的幫助。

Answer 1

這聽起來像是一個 quarkus 錯誤，您能否提出問題並@提及 stuartwdouglas，我將嘗試修復下一個將很快發布的次要版本。

Answer 2

解決方案是：github.com/quarkusio/quarkus/issues/8996

@RegisterForReflection（目標 = {xxx.class，BigDecimal.class}）
