maven-jaxb2-plugin 插件在 Spring Boot -3 中给出错误“javax-xml-bind-annotation 不存在”

Question

我正在尝试创建一个 Spring Boot 3 Soap 消费者中间件。我使用

spring-boot-starter-web-services

依赖项和 maven-jaxb2-plugin 从 WSDL 文件生成 STUB 类。但每当我尝试构建项目时，我都会收到错误。

这是我的

pom.xml

在构建项目以生成 STUB 类时，出现以下错误：

[ERROR] /E:/java/client-2/src/main/java/com/soap/client/countrySOAP/CountryName.java:[15,33] package javax.xml.bind.annotation does not exist

我收到此错误是因为从 WSDL 文件创建的类具有：

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlType;

Answer 1

你的假设是对的。您需要创建 Java 类，这些类在源代码中使用 jakarta 包（而不是 javax）。

Answer 2

您在配置中使用的插件仅针对 jaxb2 设计

<groupId>org.jvnet.jaxb2.maven2</groupId>
<artifactId>maven-jaxb2-plugin</artifactId>
<version>0.14.0</version>

好消息是，有新版本支持 JAXB 3 / JAXB 4 并生成带有

jakarta

包引用的类。

对于您的配置，我建议对插件进行以下更改：

<groupId>org.jvnet.jaxb</groupId>
<artifactId>jaxb-maven-plugin</artifactId>
<version>4.0.0</version>

您可以在项目维基的迁移指南中了解更多详细信息（因为今年已经做了很多工作来改进插件和相关工具）
