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

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

package my.pkg.types;

public enum MyEnumType {
    TYPE1,
    TYPE2
}

Now, I want to inject a value of that type into a bean property:

<bean name="someName" class="my.pkg.classes">
   <property name="type" value="my.pkg.types.MyEnumType.TYPE1" />
</bean>

...and that didn't work :(

How should I Inject an Enum into a spring bean?

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!

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.}

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.

You can just do "TYPE1".

This is what did it for me MessageDeliveryMode is the enum the bean will have the value PERSISTENT:

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

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}"/>

To be specific, set the value to be the name of a constant of the enum type, e.g., "TYPE1" or "TYPE2" in your case, as shown below. And it will work:

<bean name="someName" class="my.pkg.classes">
   <property name="type" value="TYPE1" />
</bean>

You can write Bean Editors (details are in the Spring Docs) if you want to add further value and write to custom types.

Spring-integration example, routing based on a an Enum field:

public class BookOrder {

    public enum OrderType { DELIVERY, PICKUP } //enum
    public BookOrder(..., OrderType orderType) //orderType
    ...

config:

<router expression="payload.orderType" input-channel="processOrder">
    <mapping value="DELIVERY" channel="delivery"/>
    <mapping value="PICKUP" channel="pickup"/>
</router>
