为JAX-WS库正确地从JDK-8迁移到JDK-11

Question

我正在几个缺陷管理系统之间开发几个集成(作为Maven项目)，其中一个通过WSDL公开服务，迫使我通过WS使用它们。对于后者，我成功地为JDK-8开发了代码，一切都正常。

我现在正处于从8到11的JDK迁移过程中，需要更新使用WS的集成。我知道在Java 11中，一些EE库(包括JAX)被删除了。然后，为了解决这个问题，我浏览了Web，但是经过几天的测试和剪贴，我仍然有同样的问题:无法实例化WS以与最终服务器交互(即CA SDM 14.1)。

目前，我有以下错误：

java.lang.NoSuchMethodException: com.sun.xml.bind.v2.model.nav.ReflectionNavigator.getInstance()

我的POM文件是这样的：

</dependencies>

从javax.xml.ws添加的所有依赖项使JAX在JDK 11上工作(在代码通过NoClassDefFoundError提供的连续异常之后添加)。

此外，我还使用POM中的以下内容从缺陷管理系统公开的WSDL中生成了Java类(这是第一次)：

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.6</version>
    <executions>
        <execution>
            <goals>
                <goal>
                    wsimport
                </goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <wsdlDirectory>${project.basedir}/src/main/resources/</wsdlDirectory>
        <wsdlUrls>
            <wsdlUrl>http://defect.management.system/ServiceDefinition?wsdl</wsdlUrl>
        </wsdlUrls>
        <packageName>com.ca.unicenterserviceplus.servicedesk</packageName>
        <sourceDestDir>${project.build.directory}/generated-sources/</sourceDestDir>
    </configuration>
</plugin>

然后在com.ca.unicenterserviceplus.servicedesk中复制和粘贴生成的文件，应用程序将在那里找到它们。

毕竟，我的问题是:是否有办法使事情像JDK 8那样工作呢？

Answer 1

在Oracle Java 11发行说明中，我发现了这个：

其他-libs➜JEP 320删除Java和CORBA模块。 从Java平台和JDK中删除Java和CORBA模块。这些模块在Java 9中被废弃，并声明打算在将来的版本(JEP 320)中删除它们。 以下模块已从Java 11和JDK 11中删除： java.xml.ws (JAXB，加上相关技术SAAJ和Web元数据) java.xml.bind (JAXB)

...etc

根据我从Oracle那里看到的，他们从Java11中删除了Jax，但是它仍然可以在OpenJDK：JEP 320:删除Java和CORBA模块下使用。根据那一页，

该建议假设希望在最新的JDK上编译或运行应用程序的开发人员可以找到并部署Java技术的替代版本。JAX和JAXB的参考实现( RIs )是一个很好的起点，因为它们是JDK 9中java.xml.ws和java.xml.bind模块的完全替代品。 com.sun.xml.ws : jaxws-ri (jaxws，外加SAAJ和Web元数据) com.sun.xml.bind : jaxb-ri (JAXB) JAX和JAXB的工具也可以作为Maven工件获得： wsgen和wsimport: com.sun.xml.ws : jaxws-tools，plus工具脚本模式和xjc: com.sun.xml.bind : jaxb-jxc和com.sun.xml.bind : jaxb-xjc，以及工具脚本。

由于您是在Java 8上，您可能仍然需要进行更多的调整和/或迁移到Java 9，但从我的角度来看，这是您前进的唯一途径。

总之，Oracle从Java 11中删除了Jax和相关技术，但是它们仍然可以下载和使用，下面是指向JAX-WS和JAXB的(RIs)的Maven repo的链接。詹姆斯
