JAXB版本的Changelong在https://javaee.github.io/jaxb-v2/doc/user-guide/ch02.html

摘录:

    4.1. Changes between 2.3.0.1 and 2.4.0

         JAXB RI is now JPMS modularized:

            All modules have native module descriptor.

            Removed jaxb-core module, which caused split package issue on JPMS.

            RI binary bundle now has single jar per dependency instead of shaded fat jars.

            Removed runtime class weaving optimization.

    4.2. Changes between 2.3.0 and 2.3.0.1

          Removed legacy technology dependencies:

            com.sun.xml.bind:jaxb1-impl

            net.java.dev.msv:msv-core

            net.java.dev.msv:xsdlib

            com.sun.xml.bind.jaxb:isorelax

    4.3. Changes between 2.2.11 and 2.3.0

          Adopt Java SE 9:

            JAXB api can now be loaded as a module.

            JAXB RI is able to run on Java SE 9 from the classpath.

            Addes support for java.util.ServiceLoader mechanism.

            Security fixes

Maven coordinates for JAXB artifacts jakarta.xml.bind:jakarta.xml.bind-api: API classes for JAXB. Required to compile against JAXB. org.glassfish.jaxb:jaxb-runtime: Implementation of JAXB, runtime used for serialization and deserialization java objects to/from xml. JAXB fat-jar bundles: com.sun.xml.bind:jaxb-impl: JAXB runtime fat jar. In contrast to org.glassfish.jaxb artifacts, these jars have all dependency classes included inside. These artifacts does not contain JPMS module descriptors. In Maven projects org.glassfish.jaxb artifacts are supposed to be used instead.

原来的答案

我应该在Maven项目中为JAXB RI使用哪些构件?在Maven中，你可以使用这样的配置文件:

<profile>
    <id>java-9</id>
    <activation>
        <jdk>9</jdk>
    </activation>
    <dependencies>
        <dependency>
            <groupId>org.glassfish.jaxb</groupId>
            <artifactId>jaxb-runtime</artifactId>
            <version>2.3.0</version>
        </dependency>
        <dependency>
            <groupId>javax.activation</groupId>
            <artifactId>activation</artifactId>
            <version>1.1.1</version>
        </dependency>
    </dependencies>
</profile> 

依赖树显示:

[INFO] +- org.glassfish.jaxb:jaxb-runtime:jar:2.3.0:compile
[INFO] |  +- org.glassfish.jaxb:jaxb-core:jar:2.3.0:compile
[INFO] |  |  +- javax.xml.bind:jaxb-api:jar:2.3.0:compile
[INFO] |  |  +- org.glassfish.jaxb:txw2:jar:2.3.0:compile
[INFO] |  |  \- com.sun.istack:istack-commons-runtime:jar:3.0.5:compile
[INFO] |  +- org.jvnet.staxex:stax-ex:jar:1.7.8:compile
[INFO] |  \- com.sun.xml.fastinfoset:FastInfoset:jar:1.2.13:compile
[INFO] \- javax.activation:activation:jar:1.1.1:compile

要在Eclipse中使用它，请输入Oxygen.3a Release (4.7.3a)或更高版本，按Ctrl-Alt-P，或右键单击项目Maven，然后选择概要文件。

对于Java Web Start执行，我们可以像这样使用Andy Guibert的建议:

<j2se version="1.6+" 
      java-vm-args="-XX:+IgnoreUnrecognizedVMOptions --add-modules=java.se.ee"/>

注意——add-modules中额外的“=”。请参阅此OpenJDK票据或Java平台的“理解运行时访问警告”中的最后一个注释，标准版Oracle JDK 9迁移指南。

我跟踪了这个URL，下面的设置真的帮助了我。我在Macbook Pro中使用带有STS IDE的Java 10。这招很管用。

   <dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.0</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>javax.activation-api</artifactId>
    <version>1.2.0</version>
</dependency>

对我来说，在Java 11和gradle这是什么工作:

plugins {
      id 'java'
}

dependencies {
      runtimeOnly 'javax.xml.bind:jaxb-api:2.3.1'
}

这招对我很管用:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>eclipselink</artifactId>
    <version>2.7.0</version>
</dependency>

更新

正如@Jasper所建议的，为了避免依赖于整个EclipseLink库，你也可以只依赖于EclipseLink MOXy:

Maven

<dependency>
    <groupId>org.eclipse.persistence</groupId>
    <artifactId>org.eclipse.persistence.moxy</artifactId>
    <version>2.7.3</version>
</dependency>

Gradle

compile group: 'org.eclipse.persistence', name: 'org.eclipse.persistence.moxy', version: '2.7.3'

作为我的Java 8应用程序的依赖项，该应用程序生成一个*.jar，它可以在JRE 8或JRE 9上运行，没有额外的参数。

此外，在使用JAXB API之前，需要在某处执行此命令:

System.setProperty("javax.xml.bind.JAXBContextFactory", "org.eclipse.persistence.jaxb.JAXBContextFactory");

到目前为止，作为一种变通方法，效果很好。不过，这看起来并不是一个完美的解决方案……

你可以使用——add-modules=java.xml。bind JVM选项将xml绑定模块添加到JVM运行时环境。

例如:java——add-modules=java.xml。绑定XmlTestClass
