Java 11 package javax.xml.bind does not exist
提问by Boris
I'm trying to deserialize XML data into a Java content tree using JAXB, validating the XML data as it is unmarshalled:
我正在尝试使用JAXB将 XML 数据反序列化为 Java 内容树，并在 XML 数据解组时对其进行验证：
try {
JAXBContext context = JAXBContext.newInstance("com.acme.foo");
Unmarshaller unmarshaller = context.createUnmarshaller();
unmarshaller.setSchema(schema);
FooObject fooObj = (FooObject) unmarshaller.unmarshal(new File("foo.xml"));
} catch (UnmarshalException ex) {
ex.printStackTrace();
} catch (JAXBException ex) {
ex.printStackTrace();
}
When I build the project with Java 8it's fine, but building it with Java 11fails with a compilation error:
当我使用Java 8构建项目时它很好，但是使用Java 11构建它失败并出现编译错误：
package javax.xml.bind does not exist
How do I fix the issue?
我该如何解决这个问题？

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:
您可以使用 Java EE 技术的替代版本来解决该问题。只需添加包含您需要的类的 Maven 依赖项：

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Bindingfrom Jakarta EE 8:
而不是使用旧JAXB模块，您可以通过使用修复问题雅加达XML绑定从雅加达EE 8：
<dependency>
