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。

在最近的JDK 9.0.1中，这些解决方案都不适合我。

我发现这个依赖列表对于一个正确的功能来说已经足够了，所以你不需要显式地指定——add-module(尽管它是在这些依赖的pom's中指定的)。你只需要指定以下依赖项列表:

<dependencies>
    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.0</version>
    </dependency>
    <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>

关于这个异常，我想给出一个简单易行的解决方案，只是将android studio版本降低到4.1.1或更低。确保你没有android工作室北极狐(2020.3.1)版本，因为最新版本不支持android的旧项目。

您可以使用这个依赖项

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

您需要向maven添加jaxb依赖项。glassfish实现版本2.3.2与新的jakarta EE jaxb api版本2.3.2完全兼容。

<!-- API -->
<dependency>
    <groupId>jakarta.xml.bind</groupId>
    <artifactId>jakarta.xml.bind-api</artifactId>
    <version>2.3.2</version>
</dependency>

<!-- Runtime -->
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>

在编译和运行时，添加开关——add-modules java.xml.bind

javac --add-modules java.xml.bind <java file name>

java --add-modules java.xml.bind <class file>
