How to assign bean's property an Enum value in Spring config file?

Question

I have a standalone enum type defined, something like this:

package my.pkg.types;

public enum MyEnumType {
    TYPE1,
    TYPE2
}

Now, I w

Answer 1

You can just do "TYPE1".

Answer 2

I know this is a really old question, but in case someone is looking for the newer way to do this, use the spring util namespace:

<util:constant static-field="my.pkg.types.MyEnumType.TYPE1" />

As described in the spring documentation.

Answer 3

Have you tried just "TYPE1"? I suppose Spring uses reflection to determine the type of "type" anyway, so the fully qualified name is redundant. Spring generally doesn't subscribe to redundancy!

Answer 4

Use the value child element instead of the value attribute and specify the Enum class name:

<property name="residence">
    <value type="SocialSecurity$Residence">ALIEN</value>
</property>

The advantage of this approach over just writing value="ALIEN" is that it also works if Spring can't infer the actual type of the enum from the property (e.g. the property's declared type is an interface)._{Adapted from araqnid's comment.}

Using SPEL and P-NAMESPACE:

<beans...
xmlns:p="http://www.springframework.org/schema/p" ...>
..
<bean name="someName" class="my.pkg.classes"
    p:type="#{T(my.pkg.types.MyEnumType).TYPE1}"/>

<bean class="org.springframework.amqp.core.MessageDeliveryMode" factory-method="valueOf">
    <constructor-arg value="PERSISTENT" />
</bean>
