Guide to Integrating Spring Framework, Spring MVC, and MyBatis

The article explains how to assemble a Spring container by registering core listeners in <web.xml>, including ContextLoaderListener, RequestContextListener, and IntrospectorCleanupListener, and by adding a CharacterEncodingFilter to handle UTF‑8 encoding.

It then shows the registration of org.springframework.web.servlet.DispatcherServlet as the front controller, with its own spring-mvc.xml configuration file, using a servlet mapping like *.do.

Key beans defined in spring-mvc.xml include a multipartResolver for file uploads, a custom handlerMapping that extends RequestMappingHandlerMapping, and a handlerAdapter that configures message converters, a conversion service for date handling, and a customized Jackson ObjectMapper to format dates as strings.

The view layer is set up with an InternalResourceViewResolver that resolves JSP pages using the prefix / and suffix .jsp, and the configuration enables component scanning for @Controller, @RestController, and @ControllerAdvice annotated classes in the io.flysium package.

Finally, the guide demonstrates MyBatis integration by declaring SqlSessionFactoryBean (pointing to a data source and MyBatis config file) and SqlSessionTemplate beans, completing the end‑to‑end backend setup.

Optional configurations such as LocaleResolver, ThemeResolver, HandlerExceptionResolver, and additional view resolvers are mentioned for further customization.
