Spring MVC - Spring uses sometimes RequestMappingHandlerMapping and sometimes SimpleUrlHandlerMapping

问题


I have been trying to solve this problem for past 2 days and found no answer so far. I reaserched a lot of google concerning this ;)

So the problem is that I'm trying to develop Spring MVC app using Hibernate and deploying it on Tomcat 8 local server. The thing is that on 10 runs I have about 6 times 404 Not Found page and 4 times my app i working fine and showing what I want. I made a little digging and found out in Debug logs that when request mapping fails Spring uses SimpleUrlHandlerMapping (which I do not configured) and when app works fine Spring uses RequestMappingHandlerMapping (which I configured).

A little bit of code then ;)

WebConfig.java

package pkw.config;

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = {"pkw"})
@Import({AppConfig.class, SecurityConfig.class})
public class WebConfig extends WebMvcConfigurerAdapter{


    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("classpath:bootstrap/");
    }

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public RequestMappingHandlerMapping requestMappingHandlerMapping(){
        return new RequestMappingHandlerMapping();
    }

    @Bean
    public UrlBasedViewResolver viewResolver() {
        UrlBasedViewResolver viewResolver = new UrlBasedViewResolver();
        viewResolver.setViewClass(TilesView.class);
        return viewResolver;
    }

    @Bean
    public TilesConfigurer tilesConfigurer(){
        TilesConfigurer result = new TilesConfigurer();
        result.setDefinitions("/WEB-INF/layouts/layout.xml");
        return result;
    }

}

SpringMvcInitilizer.java

package pkw.config.core;

public class SpringMvcInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {

        AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
        ctx.register(WebConfig.class);

        servletContext.addListener(new ContextLoaderListener(ctx));
        servletContext.addListener(new RequestContextListener());

        ctx.setServletContext(servletContext);

        Dynamic servlet = servletContext.addServlet("Enter", new DispatcherServlet(ctx));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);

    }

}

EnterController.java

package pkw.controllers;

@Controller
public class EnterController {

    private static final Logger logger = LogManager.getLogger(EnterController.class);

    @Autowired
    IUserDAO userDAO;

    @Autowired
    IUserRoleDAO userRoleDAO;

    @Autowired
    DatabaseFinder finder;

    @Autowired
    PasswordEncoder passwordEncoder;

    @RequestMapping(value = {"/", "/main"}, method = {RequestMethod.GET, RequestMethod.HEAD})
    public String enterMain(Model model) {

        return "main";
    }


    @RequestMapping(value = "/login", method = {RequestMethod.GET, RequestMethod.HEAD})
    private String login(@RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout",
            required = false) String logout, @RequestParam(value = "denied", required = false) String denied, @RequestParam(value = "success", required = false) String success,
                         Model model) {

        if (error != null) {
            model.addAttribute("error", "1");
        }

        if (logout != null) {
            model.addAttribute("logout", "1");
        }

        if (denied != null) {
            model.addAttribute("denied", "1");
        }

        if (success != null) {
            Authentication auth = SecurityContextHolder.getContext().getAuthentication();

            userBean.setLoggedUser(userDAO.findByPesel(auth.getName()));
            model.addAttribute("success", "1");
        }


        return "main";

    }
}

and more but not concerning the problem anymore (at least I think so... ^^)

So the question is why Spring uses sometimes one mapping handler and sometimes antoher one even when I configured which one it suppose to use?

It's weird because I get two different results, one working and one not from exactly the same code O.o

P.S I checked all paths to solve this problem concerning bad deployment, Intellij not cleaning Tomcat properly on restart and so on. I also tried tune Tomcat memory. Nothing of it gave me the solution :/

Edit for Tiles Config as suggested by iamiddy

layout.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
        "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">

<tiles-definitions>
    <definition name="DefaultTemplate" template="/WEB-INF/pages/template/SiteTemplate.jsp">
        <put-attribute name="title" value="Home"/>
        <put-attribute name="header" value="/WEB-INF/pages/header.jsp"/>
        <put-attribute name="navbar" value="/WEB-INF/pages/navbar.jsp"/>
        <put-attribute name="body" value=""/>
        <put-attribute name="footer" value="/WEB-INF/pages/footer.jsp"/>
    </definition>

    <definition name="main" extends="DefaultTemplate">
        <put-attribute name="body" value="/WEB-INF/pages/main.jsp"/>
    </definition>
    <definition name="addUser" extends="DefaultTemplate">
        <put-attribute name="body" value="/WEB-INF/pages/addUser.jsp" />
    </definition>
    <definition name="users" extends="DefaultTemplate">
        <put-attribute name="body" value="/WEB-INF/pages/users.jsp" />
    </definition>
</tiles-definitions>

TilesConfigurer and ViewResolver are in WebConfig.java


回答1:


try to add the following requestHandlerMapping beans explicitly, if that 

  <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>



回答2:


make sure that you are always returning the tiles definition and not the jsp pages as configures in your "/WEB-INF/layouts/layout.xml"

If you are already doing that please share the tiles definition and the resource file for the url & Tiles class.
