Quarkus Jackson InvalidDefinitionException 找不到类型 [简单类型，类 java.math.BigDecimal] 的（映射）密钥反序列化器

【问题描述】：

我尝试使用 Quarkus 开发一个 Rest API，仅从来自 POST 有效负载的数据生成 PDF。 只有当应用程序在本机模式下运行时，我才会出现以下异常：

我的数据如下所示：

@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;

}

一些嵌入对象的 Map 带有 BigDecimal Key ：

@Getter
@Setter
public class ConsolidatedTaxes {

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

    @NotNull
    @Valid
    private ValueAddedTax total;

}

还有一些直接使用 BigDecimal ：

@Getter
@Setter
public class ValueAddedTax {

    @NotNull
    private BigDecimal baseAmount;

    @NotNull
    private BigDecimal taxAmount;

    @NotNull
    private BigDecimal includingTaxAmount;

}

我的依赖：

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

我真的不明白什么对象有问题要反序列化。在开发模式下运行时不会出现问题。

我如何进行反序列化：

<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 负载示例：

{
    "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"
    }
}

什么是仅在本机编译期间才能产生这种行为的附加内容？ 感谢您的帮助。

【问题讨论】：

  • 能否将 JSON 有效负载以及如何反序列化它添加到您的问题中？
  • @JanRieke 我添加了你的要求。谢谢你的帮助:)
  • 如果我更改有效负载结构并且不使用 Map，则不会出现此问题。我相信这个问题是因为在本机模式下构建时，GraalVM 会进行树摇动以仅发送必要的东西，但它无法嵌入 BigDecimalDeserializer，因为它不存在显式链接。但是当我尝试在reflection-config.json中指向内部静态类BigDecimalDeserializer时，找不到该类。

【解决方案1】：

这听起来像是一个 quarkus 错误，您能否提出一个问题并@提及 stuartwdouglas，我会尝试修复即将发布的下一个次要版本。

【解决方案2】：

解决方案在问题中：github.com/quarkusio/quarkus/issues/8996

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