JAXB API的Java 8到Java 11迁移问题

Question

我们正在将我们的项目从Java8迁移到Java11。其中一个API依赖于使用JAXB的库。正如我们所知，JAXB是从JAVA11中删除的，我们开始在库的POM中包含JAXB依赖项。

 <!-- https://mvnrepository.com/artifact/jakarta.xml.bind/jakarta.xml.bind-api -->
  <!-- API -->
  <dependency>
    <groupId>jakarta.xml.bind</groupId>
    <artifactId>jakarta.xml.bind-api</artifactId>
    <version>2.3.3</version>
  </dependency>
  <!-- Runtime -->
  <dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
  </dependency>

当我们运行API项目时，一切正常

mvn spring boot:运行

但是，当API部署在QA服务器中，并使用带有-

java-jar Sample-api 3.0.0-SNAPSHOT. jar

当调用依赖于JAXB的库时，API抛出以下错误-

Caused by: javax.xml.bind.JAXBException: Implementation of JAXB-API has not been found on module path or classpath.

• 除此之外：

Answer 1

JAXB需要javax。激活模块，成为雅加达。更名为Jakartae后激活。包括这种依赖关系应该有帮助：

<dependency>
    <groupId>jakarta.activation</groupId>
    <artifactId>jakarta.activation-api</artifactId>
    <version>2.0.0</version>
</dependency>
