Proper way to use Spring JAXB Marshaller with Java 9 without defining additional modules

Question

To illustrate my issue, I created a small spring boot sample application. The purpose of the application is to create a Jaxb2Marshaller bean.

Answer 1

The following has worked for me

<dependency>
  <groupId>org.glassfish.jaxb</groupId>
  <artifactId>jaxb-runtime</artifactId>
  <version>2.3.0</version>
</dependency>

Answer 2

Try adding the following:

<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.3.0</version>
</dependency>
<dependency>
    <groupId>com.sun.activation</groupId>
    <artifactId>javax.activation</artifactId>
    <version>1.2.0</version>
</dependency>

jaxb-core contains com.sun.xml.bind.v2.model.annotation.AnnotationReader (and seems to be a required dependency of jaxb-runtime, at least in your case), while javax.activation is needed by jaxb-api due to the usage of DataHandler by the latter.

Also, there is no a single bean class, so the marshaller will fail initialization. I've added the following

@XmlRootElement
public class MyBean {
}

and replaced

bean.setContextPath("ch.sahits.game.helloworld");

with

bean.setClassesToBeBound(MyBean.class);

after which the application has started.
