问题描述

我们正在考虑将一些遗留代码升级到Java 10.由于默认情况下看不到JAXB（编辑：并且正确的长期解决方案是不以使用各种JVM标志来规避症状，但是正确修复它）我已将此片段添加到我的pom.xml：

We are looking at upgrading some legacy code to Java 10. As JAXB is not visible by default ( and the proper long term solution is not to circumvent the symptom using various JVM flags, but fix it properly) I have added this snippet to my 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，启动时仍会向stderr打印警告。显然这不是正确的解决方案。

Unfortunately there is still a warning printed at startup to stderr. Apparently this is not the correct fix.

什么是在这里使用适当的依赖关系来解决这个问题？

What are the proper dependencies to use here to resolve this problem?

推荐答案

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

jaxb-ri runtime uses ClassLoader#defineClass / Unsafe#defineClass to do some bytecode modification in runtime to optimize performance. ClassLoader#defineClass is tried first which causes the warning.

在jaxb-ri master中完全删除了这个遗留优化（在2.3.0之后，尚未发布）。

This legacy optimization is removed completely in jaxb-ri master (after 2.3.0, not released yet).

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

To disable this optimization for 2.3.0, set system property com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize.

在下一个jaxb-ri版本更新到最新版本之后将删除警告。
jaxb-core工件将停止支持JPMS支持。正确的pom看起来像：

After next jaxb-ri release updating to newest version will remove the warning. jaxb-core artifact will be discontinued in favor for JPMS support. Correct pom will look like:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.4.0</version> <!-- not released yet -->
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.4.0</version> <!-- not released yet -->
</dependency>

如果您希望尽早尝试，可以从以下位置选择最新推出的版本：
https://maven.java.net/content/groups/ promote / org / glassfish / jaxb / jaxb-runtime /

If you wish to try early, you can pick latest promoted build from: https://maven.java.net/content/groups/promoted/org/glassfish/jaxb/jaxb-runtime/
