Answer 1

add

 @Bean(initMethod = "initialize")
 public StaticBasicParserPool parserPool() {
      return new StaticBasicParserPool();
 }

I don't do xml configuration but I guess you can easily translate this bean declaration.

Answer 2

In xml just add the bean

<!-- XML parser pool needed for OpenSAML parsing -->
<bean id="parserPool" 
class="org.opensaml.xml.parse.StaticBasicParserPool"
    init-method="initialize">
    <property name="builderFeatures">
        <map>
            <entry 
key="http://apache.org/xml/features/dom/defer-node-expansion"
                value="false" />
        </map>
    </property>
