2: 1 Injecting enums in Spring
3: To inject java.commons.lang.Enum, we need to use the static method and pass in the String. ie given:
4: {code:java}
5: import org.apache.commons.lang.enum.Enum;
6: public final class SortEnum extends Enum {
7: /** ascending sort order. */
8: public static final SortEnum ASC = new SortEnum("ASC");
9: /** descending sort. */
10: public static final SortEnum DESC = new SortEnum("DESC");
11: /** no sort order specified. */
12: public static final SortEnum NO_SORT = new SortEnum("NO_SORT");
13: /**
14: * callers should use convience methods.
15: * @param dir to sort
16: */
17: private SortEnum(String dir) {
18: super(dir);
19: }
20: /**
21: * SortEnum to use.
22: * @param dir requied
23: * @return enum represention for the dir
24: */
25: public static SortEnum getEnum(String dir) {
26: return (SortEnum) getEnum(SortEnum.class, dir);
27: }
28: }
29: {code}
30: {code:xml}
31: <beans>
32: <bean id="ASC"
33: class="com.marandcustomsolutions.SortOrder"
34: factory-method="getEnum" singleton="true">
35: <constructor-arg><value>ASC</value> </constructor-arg>
36: </bean>
37: </beans>
