Specify a package instead of “classesToBeBound” for spring Jaxb2Marshaller

问题

I am trying to use Jaxb2Marshaller to marshal a set of java classes using spring. I know this can be done using the following code

<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="classesToBeBound">
        <list>
            <value>com.example.test1</value>
            <value>com.example.test2</value>
        </list>
    </property>
</bean>

What I would like to do is instead of specifying a list of classes, I would like to specify just the package name containing all the classes ( in the above case com.example).

Does anyone know of a way to do this, or any other way which does not require me to list all the classes. any help would be appreciated !

Thanks.

From Spring 3.1 (i think) you can use also the packagesToScan property, which accepts wildcards. It just doesn't work with elements without the @XmlRootElement annotation, just like the contextPath property. These need generated object-factory.

Could look like:

<property name="packagesToScan">
    <list>
        <value>com.test.*</value>
        <value>com.*.test</value>
    </list>
</property>

You could set the contextPath with the following syntax:

<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPath" value="com.example"/>
</bean>

If you are using the new version of JAXB then you can use something like this in your application context if you add the oxm namespace to your xml file.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:oxm="http://www.springframework.org/schema/oxm"
       xsi:schemaLocation="
           http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
           http://www.springframework.org/schema/oxm
           http://www.springframework.org/schema/oxm/spring-oxm-3.1.xsd">
  <oxm:jaxb2-marshaller id="jaxbMarshaller" contextPath="com.example"/>
  <!-- other beans -->
</beans>

I have a production level program running with these, so let me know if you have any more questions.

Good Luck.
