Java 11包javax.xml.bind不存在 [英] Java 11 package javax.xml.bind does not exist

问题描述

我正在尝试使用 JAXB ，验证XML数据，因为它是未编组的：

I'm trying to deserialize XML data into a Java content tree using JAXB, validating the XML data as it is unmarshalled:

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();
}

当我使用 Java 8 构建项目时，它是很好，但使用 Java 11 构建它会因编译错误而失败：

When I build the project with Java 8 it's fine, but building it with Java 11 fails with a compilation error:

package javax.xml.bind does not exist

如何解决此问题？

推荐答案

根据发行说明，Java 11删除了Java EE模块：

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK


• Java 9 - DEPRECATED


• Java 10 - DEPRECATED


• Java 11 -
  REMOVED


• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

参见 JEP 320 了解更多信息。

您可以使用Java EE技术的替代版本来解决此问题吉斯。只需添加包含所需类的Maven依赖项：

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<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>
