Spring: In my context.xml, I have: <util:set id=someIDs set-class=java.util.HashSet value-type=java.lang.String> <value>W000000001</value> <value>W000000003</value> <value>W000000009</value> </util:set>

Spring: In my context.xml, I have:

<util:set id='someIDs'        set-class='java.util.HashSet'       value-type='java.lang.String'>          <value>'W000000001'</value>          <value>'W000000003'</value>          <value>'W000000009'</value>         </util:set>

In my Java bean, the implementation is:

private Set<String> someSet =                ComUtilities.uncheckedCast(getApplicationContext()              .getBean('someIDs'));  boolean found = someSet.contains('W000000009');

After the execution of avobe code block, found is very weirdly false! How come? Any suggestion/idea? Thanks a bunch.

  1. Off the top of my head – I’m pretty sure that Spring doesn’t require double quotes for String data. So it’s probably inserting those strings into the map with actual double-quote characters at the start and the end.

    Try checking

    boolean found = someSet.contains('\'W000000009\'');

    to see if this is the case.
