I want to specify in property file, which bean will be autowired.
I found the solutions but all of them are using @Profile annotation, which means that they are based on specified profile, not specified property.
I did it in that way:
@Configuration
public class WebServiceFactory {
@Value("${webservice}")
private String webService;
@Lazy
@Autowired
private GraphQLService graphQLService;
@Lazy
@Autowired
private RestService restService;
@Primary
@Bean
WebService getWebService() {
switch (webService) {
case "graphQlService":
return graphQLService;
case "restService":
return restService;
default:
throw new UnsupportedOperationException("Not supported web service.");
}
}
}
Bean type I want to autowire is interface WebService, GraphQLService and RestService are it's implementations.
Is there any better way to do this?
You can do this using the normal configuration of Spring.
class A{
B bBean;
...//setters/getters here.
}
class B{}
You can have a configuration file (It also can be a configuration class)
<bean id = "a" class = "A">
<property name="bBean" ref="b"/>
</bean>
<bean id = "b" class = "B">
</bean>
The bBean configuration can be in a different file, so you can import it from you classpath. Instead of using a property file you use a configuration file in the classpath o systemfile. If B is a different implementation then you modify your config file with the right class.
