Use Maven, Java 8, Spring 4, Intellij. Use maven dependency to download spring.
Setter Injection. Constructor Injection (Index based) or autowired in applicationContext.xml. Need to input each bean manually.
Use annotations @Repository, @Service, @Component, @Autowired. Use below in applicationContext.xml to scan package.
<context:annotation-config />
<context:component-scan base-package="com.practice.spring"/>Field, Setter or Constructor Injection.
Add AppConfig.java Class and use @Configuration the class level annotation, @Bean the method level annotation.
If we want to use @Autowired annotation configuration, add @ComponentScan({"com.practice"}) in AppConfig.java.
