I am developing a little demo project with Spring MVC on a Tomcat with hibernate and JSPs. The application was working with thymeleaf as a view resolver but I need to rewrite my thymeleaf template as a .JSP. So I needed to reconfig everything. I am also trying to only use annotation configuration files without any xml.
The problem is that I am seeing the source code of my JSP-File without resolving.
The Request-Mapping and the program logic already worked with thymeleaf + spring. I am getting no error messages in the log files. I tried a lot of changes so my config files may be inconsistent at the moment. Any pointers or advice is appreciated.
My config files are below:
MyWebAppInitializer:
public class MyWebAppInitializer implements WebApplicationInitializer {
private static final String CONFIG_LOCATION = "MvcConfiguration";
private static final String MAPPING_URL = "/";@Override
public void onStartup(ServletContext servletContext) throws ServletException {
WebApplicationContext context = getContext();
servletContext.addListener(new ContextLoaderListener(context));
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("DispatcherServlet", new DispatcherServlet(context));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping(MAPPING_URL);
}
private AnnotationConfigWebApplicationContext getContext() {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.setConfigLocation(CONFIG_LOCATION);
return context;
}
}
MvcConfiguration:
class MvcConfiguration extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
BenutzerController:
@Controller
public class BenutzerController {
@Autowired
BenutzerRepository repository;
@ModelAttribute("Benutzer")
public Benutzer loadEmptyModelBean() {
return new Benutzer();
}
@ModelAttribute("userList")
public List < Benutzer > userList() {
return toList(repository.findAll());
}
@RequestMapping("/verwaltung")
public String verwaltung(@RequestParam(value = "message", required = false, defaultValue = "Defaultvalue") String message, ModelMap model) {
model.addAttribute("message", message);
return "verwaltung";
}
