我们正在考虑将一些遗留代码升级到 Java 10。由于默认情况下 JAXB 不可见（编辑：正确的长期解决方案不是使用各种 JVM 标志来规避症状，而是正确修复它）我已将此片段添加到我的 pom.xml：

    <!-- https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api -->
    <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-core</artifactId>
        <version>2.3.0</version>
    </dependency>
    <dependency>
        <groupId>com.sun.xml.bind</groupId>
        <artifactId>jaxb-impl</artifactId>
        <version>2.3.0</version>
    </dependency>

不幸的是，在启动时仍然会向 stderr 打印警告。显然这不是正确的解决方法。

在这里使用什么正确的依赖项来解决这个问题？

jaxb-ri 运行时用于ClassLoader#defineClass / Unsafe#defineClass在运行时进行一些字节码修改以优化性能。ClassLoader#defineClass首先尝试导致警告。

这种遗留优化在 jaxb-ri master 中被完全删除（2.3.0 之后，尚未发布）。

要为 2.3.0 禁用此优化，请设置系统属性 com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize。

在下一个 jaxb-ri 版本更新到最新版本后将删除​​警告。将停止 jaxb-core 工件以支持 JPMS。正确的 pom 将如下所示：

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.4.0</version> 
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.4.0</version> 
</dependency>

如果您想早点尝试，可以从以下位置选择最新的升级版本： https ://maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/

感谢@Roman Grigoriadi，他是对的，更新2.4版本修复了警告问题。

只需将以下依赖项添加到pom文件中

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.4.0-b180830.0359</version>
</dependency>
<dependency>
  <groupId>org.glassfish.jaxb</groupId>
  <artifactId>jaxb-runtime</artifactId>
  <version>2.4.0-b180608.0325</version>
</dependency>

我只花了半天时间浏览关于这个主题的旧博客和帖子，大多数已经过时且无法正常工作。或者只在运行时处理警告。截至 2020 年 12 月，以下内容适用于 Java 15，没有任何错误或警告：

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.2</version>
</dependency>

要使 JAXB 2.3.3 与 JDK 16 一起使用（即与 JDK 1.8 到 17 EA 一起使用）：始终在 MANIFEST.MF 中添加“Multi-Release: true”！

看我的评论：

https://github.com/eclipse-ee4j/jaxb-ri/issues/1197#issuecomment-810908755

这是我在项目中使用 JAXB 2.3.3 的具体 maven（显式）依赖项：
