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 want to inject a value of that type into a bean property    lt bean name  someName  class  my pkg classes  gt      lt property name  type  value  my pkg types MyEnumType TYPE1    gt   lt  bean gt       and that didn t work     How should I Inject an Enum into a spring bean

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.}

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

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    lt util constant static-field  my pkg types MyEnumType TYPE1    gt    As described in the spring documentation

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    lt bean name  someName  class  my pkg classes  gt      lt property name  type  value  TYPE1    gt   lt  bean gt

You can just do  TYPE1

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
