Java 如何使用Thymeleaf绑定HTML5和SpringMVC4？

好的，我设法使用Thymeleaf获得了我的应用程序，现在我需要将所有JSP页面重建为HTML5。首先也是最重要的一点，我需要能够使用用户名和密码登录到应用程序，这在JSP上非常有效

将HTML5页面分配为视图层的My bean定义为：

@Bean
public ViewResolver viewResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setPrefix("/WEB-INF/html/");
    templateResolver.setSuffix(".html");

    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver);

    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(engine);

    return viewResolver;
}

@Controller
public class LoginController {

    @Autowired
    UserProfileService userProfileService;

    @Autowired
    UserService userService;

    @RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
    public String homePage(ModelMap model) {
        String user = getPrincipal();
        model.addAttribute("greeting", "Hi, Welcome to HRM");
        model.addAttribute("user", user);
        model.addAttribute("roles", initializeProfiles());
    return "welcome";
    }

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String loginPage() {
        return "login";
    }

    @RequestMapping(value="/logout", method = RequestMethod.GET)
    public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        if (auth != null){    
            new SecurityContextLogoutHandler().logout(request, response, auth);
        }
    return "redirect:/login?logout";
    }

    private String getPrincipal(){
        String userName = null;
        Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

        if (principal instanceof UserDetails) {
            userName = ((UserDetails)principal).getUsername();
        } else {
            userName = principal.toString();
        }
        return userName;
    }
(...)
}

我的LoginController定义为：

@Bean
public ViewResolver viewResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setPrefix("/WEB-INF/html/");
    templateResolver.setSuffix(".html");

    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver);

    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(engine);

    return viewResolver;
}

@Controller
public class LoginController {

    @Autowired
    UserProfileService userProfileService;

    @Autowired
    UserService userService;

    @RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
    public String homePage(ModelMap model) {
        String user = getPrincipal();
        model.addAttribute("greeting", "Hi, Welcome to HRM");
        model.addAttribute("user", user);
        model.addAttribute("roles", initializeProfiles());
    return "welcome";
    }

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String loginPage() {
        return "login";
    }

    @RequestMapping(value="/logout", method = RequestMethod.GET)
    public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
        Authentication auth = SecurityContextHolder.getContext().getAuthentication();
        if (auth != null){    
            new SecurityContextLogoutHandler().logout(request, response, auth);
        }
    return "redirect:/login?logout";
    }

    private String getPrincipal(){
        String userName = null;
        Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

        if (principal instanceof UserDetails) {
            userName = ((UserDetails)principal).getUsername();
        } else {
            userName = principal.toString();
        }
        return userName;
    }
(...)
}

旧的

我真的不熟悉Thymeleaf和HTML5如何处理请求。在JSP表单上，操作是显式的，submit type按钮或链接将访问控制器上的POST方法并处理请求。但是如何将视图（Thymeleaf+HTML5）绑定到控制器（Spring）层呢

看看您的代码，您有一个表单，在JSP模板中同时指定了action和method属性，但在Thymeleaf模板中完全缺少表单。您应该能够使用th:attr、th:action或th:method属性重新创建相同的表单。对于正确映射的请求，您的控制器应该可以毫无问题地处理它

有关更多详细信息，请参阅Thymeleaf文档的第5节：
