Creating and using bean definitions4.3.2.2. String-based accessBeans may be accessed via the traditional string-based getBean() API as well. Of course this is not type-safeand requires casting, but avoids any potential ambiguity entirely:JavaConfigApplicationContext context = new JavaConfigApplicationContext(...);Service service = (Service) context.getBean("myService");(1.0.0.m4-SNAPSHOT)
Chapter 5. Modularizing configurationsWhile the simplest configuration may be expressed as a single class that exposes several beans, it is oftendesirable to modularize configurations for reuse and clarity.5.1. Partitioning bean definitions across multiple@Configuration classesThe simplest technique for modularizing configurations is to simply split up large @Configuration classescontaining many @Bean definitions into multiple smaller classes:// monolithic configuration@Configurationpublic class AppConfig {@Beanpublic ServiceA serviceA() {// ...}@Beanpublic ServiceB serviceB() {// ...}}// assume many bean definitions followThe above configuration class might be supplied as a parameter to JavaConfigApplicationContext:JavaConfigApplicationContext context = new JavaConfigApplicationContext(AppConfig.class);ServiceA serviceA = context.getBean(ServiceA.class);ServiceB serviceB = context.getBean(ServiceB.class);We can easily partition this configuration such that bean definitions are spread across two classes, instead ofone:// partitioned configuration@Configurationpublic class AppConfigA {@Beanpublic ServiceA serviceA() {// ...}}@Configurationpublic class AppConfigB {@Beanpublic ServiceB serviceB() {// ...}}Now simply supply both configuration classes to the constructor of JavaConfigApplicationContext:JavaConfigApplicationContext context =new JavaConfigApplicationContext(AppConfigA.class, AppConfigB.class);// both beans are still available in the resulting application contextServiceA serviceA = context.getBean(ServiceA.class);ServiceB serviceB = context.getBean(ServiceB.class);Spring JavaConfig 18
