Structure:
config: Create config package for root and webconfig
web: Create web package for controller
view: Create home.jsp under WEB-INF/views
View
Create jsp page for view under WEB-INF/views, say home.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <body> <h1>Hello, Welcome!</h1> <a href="<c:url value="/"/>">home</a> <a href="<c:url value="/register"/>">Register</a> </body> </html>
Config
Create Root and Web Configs under config package,
Root Config:
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
/**
* Created by zillani on 11/19/2016.
* Simple RootConfig
*/
@Configuration
@ComponentScan(basePackages = {"com.test"},
excludeFilters = {
@ComponentScan.Filter(type = FilterType.ANNOTATION, value = EnableWebMvc.class)
})
public class RootConfig {
}
Web Config:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
/**
* Created by zillani on 11/19/2016.
* Minimal Configuration for Spring MVC
*/
@Configuration
@EnableWebMvc
@ComponentScan("com.test")
public class WebConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){
configurer.enable();
}
}
Application Initializer:
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
/**
* Created by zillani on 11/19/2016.
* The DispatcherServlet for the app
*/
public class TestAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class<?>[]{ RootConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[]{ WebConfig.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
}
Controller:
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import static org.springframework.web.bind.annotation.RequestMethod.GET;
/**
* Created by zillani on 11/19/2016.
* A Simple Controller
*/
@Controller
@RequestMapping("/")
public class HomeController {
@RequestMapping(method = GET)
public String home() {
return "home";
}
}
Deploy:
