I'm new to Spring MVC and Hibernate. I'm trying to start a project by following tutorials but I have been running into problems as my project structure is not consistent with the tutorials I am reading.
I have downloaded the latest STS and I do see the option of creating an Spring MVC project. However it is based on Spring 3 and still uses XML files. From what I have read it looks like there is a way to do it without XML files since Spring 3. I prefer annotations over XML files greatly.
How can I create a Spring MVC 4 application that is based on annotations and relies on xml files minimally?
EDIT:
I want to create a web project
Here is a squeletal example of full java configuration. You will need :
- a class extending
AbstractAnnotationConfigDispatcherServletInitializer
to replace the old web.xml
file
- one or more
@Configuration
annotaded class(es) to initialize the root context (replaces the old applicationContext.xml
)
- one or more
@Configuration
annotaded class(es) to initialize the DispatcherServlet
context (replaces the old dispatcher-servlet.xml
)
This is the web.xml
:
public class WebAppConf extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
// declare root context configuration classes
return new Class<?>[]{ RootConf.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
// declare servlet context configuration classes
return new Class<?>[]{ ServletConf.class };
}
@Override
protected String[] getServletMappings() {
// mapping of DispatcherServlet
return new String[]{"/"};
}
@Override
protected void customizeRegistration(Dynamic registration) {
// additional configuration, here for MultipartConfig
super.customizeRegistration(registration);
MultipartConfigElement multipartConf = new MultipartConfigElement("", 200000L, -1L, 0);
registration.setMultipartConfig(multipartConf);
}
}
RootConf
will declare business model, service and dao beans and is not shown here.
ServletConf
declares the controllers and servlet configuration :
@Configuration
@EnableWebMvc
// declare where to find annotated controllers
@ComponentScan({"org.example.web"})
public class ServletConf extends WebMvcConfigurerAdapter {
@Bean
MultipartResolver multipartResolver() {
return new StandardServletMultipartResolver();
}
@Bean
ViewResolver internalViewResolver() {
// the view resolver bean ...
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
return resolver;
}
}
As said above, it is squeletal, but it comes from a working minimal example so you should be able to start with that and extend it at will. In my example, the above three classes live in a org.example.config
package that will never be scanned for autodetecting other configuration classes or annotated beans.
Hope it helps ...
I know this doesn't answer your question fully, but hopefully the links will be useful.

as well as AnnotationConfigWebApplicationContext
Also, if you have the time, reading the relevant sections of Spring's MVC chapter of their documentation is helpful.

The latest versions of STS integrate the Spring guides from https://spring.io/guides directly, try the "Import Spring Getting Started Content" wizard. There are good guides included for creating a Spring Boot based web service, for example, among many others.
