22 | * This is an implementation of the ObjectFactory interface which simply delegates to | |
23 | * the Spring ApplicationContext. Since the delegation happens each time a call to | |
24 | * getOrCreate() is made, this will correctly handle Spring beans which are | |
25 | * non-singletons (factory beans, etc.) | |
26 | * | |
27 | * Singleton usage: | |
28 | * | |
29 | * <model> | |
30 | * <service name="myOrangeService"> | |
31 | * <service> | |
32 | * <spring-object bean="myBean"/> | |
33 | * </service> | |
34 | * </service> | |
35 | * </model> | |
36 | * | |
37 | * <spring:bean id="myBean" class="com.foo.Bar"/> | |
38 | * | |
39 | * Non-singleton usage: | |
40 | * | |
41 | * <model> | |
42 | * <service name="myOrangeService"> | |
43 | * <service> | |
44 | * <spring-object bean="myFactoryBean"/> | |
45 | * </service> | |
46 | * </service> | |
47 | * </model> | |
48 | * | |
49 | * <spring:bean id="myFactoryBean" class="com.foo.BarFactory" factory-method="getNewBar"/> | |
