Development/Java & J2EE/Spring/Enums ---- 1 Injecting enums in Spring To inject java.commons.lang.Enum, we need to use the static method and pass in the String. ie given: {code:java} import org.apache.commons.lang.enum.Enum; public final class SortEnum extends Enum { /** ascending sort order. */ public static final SortEnum ASC = new SortEnum("ASC"); /** descending sort. */ public static final SortEnum DESC = new SortEnum("DESC"); /** no sort order specified. */ public static final SortEnum NO_SORT = new SortEnum("NO_SORT"); /** * callers should use convience methods. * @param dir to sort */ private SortEnum(String dir) { super(dir); } /** * SortEnum to use. * @param dir requied * @return enum represention for the dir */ public static SortEnum getEnum(String dir) { return (SortEnum) getEnum(SortEnum.class, dir); } } {code} {code:xml} <beans> <bean id="ASC" class="com.marandcustomsolutions.SortOrder" factory-method="getEnum" singleton="true"> <constructor-arg><value>ASC</value> </constructor-arg> </bean> </beans> {code} ---- 1 Injecting list, set, map, and props {code:xml} <bean id="moreComplexObject" class="example.ComplexObject"> <!-- results in a setPeople(java.util.Properties) call --> <property name="people"> <props> <prop key="HarryPotter">The magic property</prop> <prop key="JerrySeinfeld">The funny property</prop> </props> </property> <!-- results in a setSomeList(java.util.List) call --> <property name="someList"> <list> <value>a list element followed by a reference</value> <ref bean="myDataSource"/> </list> </property> <!-- results in a setSomeMap(java.util.Map) call --> <property name="someMap"> <map> <entry> <key><value>yup an entry</value></key> <value>just some string</value> </entry> <entry> <key><value>yup a ref</value></key> <ref bean="myDataSource"/> </entry> </map> </property> <!-- results in a setSomeSet(java.util.Set) call --> <property name="someSet"> <set> <value>just some string</value> <ref bean="myDataSource"/> </set> </property> {code} 2006-07-22 11:48:39.0 2006-07-22 11:48:39.0
