I am using spring 4.0.2, eclipse JEE marse, Tomcat v7.0. I have to test an example from here. My project structure is:
Java Resources src com.test.config HelloConfig.java HelloController.java HelloInitializer.java WebContent META-INF MANIFEST.MF WEB-INF lib view welcome.jsp Content of my HelloConfig.java is:
package com.test.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.ImportResource; import org.springframework.web.servlet.ViewResolver; import org.springframework.web.servlet.config.annotation.EnableWebMvc; import org.springframework.web.servlet.view.InternalResourceViewResolver; import org.springframework.web.servlet.view.JstlView; @Configuration @EnableWebMvc @ComponentScan(basePackages = "com.test.config") public class HelloConfig { @Bean public ViewResolver viewResolver() { InternalResourceViewResolver viewResolver = new InternalResourceViewResolver(); viewResolver.setViewClass(JstlView.class); viewResolver.setPrefix("/WEB-INF/view/"); viewResolver.setSuffix(".jsp"); return viewResolver; } } And content of my HelloInitializer.java:
package com.test.config; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.ServletRegistration; import org.springframework.web.WebApplicationInitializer; import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; import org.springframework.web.servlet.DispatcherServlet; public class HelloInitializer implements WebApplicationInitializer { public void onStartup(ServletContext container) throws ServletException { AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext(); ctx.register(HelloConfig.class); ctx.setServletContext(container); ServletRegistration.Dynamic servlet = container.addServlet("dispatcher", new DispatcherServlet(ctx)); servlet.setLoadOnStartup(1); servlet.addMapping("/hello/*"); } } And content of my HelloController.java:
package com.test.config; import org.springframework.stereotype.Controller; import org.springframework.ui.ModelMap; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; @Controller @RequestMapping("/") public class HelloController { @RequestMapping(method = RequestMethod.GET) public String sayHello(ModelMap model) { model.addAttribute("greeting", "Hello World from Spring 4 MVC"); return "welcome"; } @RequestMapping(value = "/helloagain", method = RequestMethod.GET) public String sayHelloAgain(ModelMap model) { model.addAttribute("greeting", "Hello World Again, from Spring 4 MVC"); return "welcome"; } } But I ran this project on the server and got this error:
