Spring - Thymeleaf - 404错误
Spring - Thymeleaf - 404错误
提问于 2014-05-09 19:22:51
我过去曾与Spring合作过一个大型项目，但我从未从零开始使用Spring应用程序。
这就是我现在正在做的练习，因为我有一个项目，即将需要它。
我成功地制作了一个简单的Spring，它使用了.JSP页面(使用注释，而不是XML)。不过，我想使用Thymeleaf，并开始了我的转换过程。
现在，我得到了一个404错误，我的HomeController类甚至没有被击中，看起来是这样的。
在控制台输出中没有错误。
我有谷歌搜索，阅读教程，和代码示例。第二双眼睛就好了。谢谢！:)
注意:从.JSP到Thymeleaf，惟一的更改是添加ThymeleafConfig类。我不明白从工作到不工作是怎么回事。
这是我的密码：
WebInit.java
public class WebInit implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
// Creates the root application context
AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext();
appContext.register(ServletConfig.class);
appContext.setDisplayName("REPLACE ME");
appContext.setConfigLocation("com.demo.config");
// Creates the Spring Container shared by all Servlets and Filters
servletContext.addListener(new ContextLoaderListener(appContext));
// Further configures the servlet context
ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
"dispatcher", new DispatcherServlet(appContext));
dispatcher.setLoadOnStartup(1);
dispatcher.setAsyncSupported(true);
dispatcher.addMapping("/");
}
}ServetConfig.java
@Configuration
@Import(WebConfig.class)
@ImportResource({/*"classpath:META-INF/spring/persistence-context.xml"*/})

}WebConfig.java
@Configuration
@ComponentScan("com.illinois.dnr")
@EnableAspectJAutoProxy
@EnableWebMvc
@Import({ThymeleafConfig.class})
public class WebConfig extends WebMvcConfigurerAdapter {
// Maps resources path to webapp/resources
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations(
"/resources/");
}
// Provides internationalization of messages
@Bean
public ResourceBundleMessageSource messageSource() {
ResourceBundleMessageSource source = new ResourceBundleMessageSource();
source.setBasename("messages");
return source;
}
}Thymeleaf.java
@Configuration
public class ThymeleafConfig {
@Bean
public ServletContextTemplateResolver templateResolver() {
ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".html");

return engine;
}
@Bean
public ThymeleafViewResolver thymeleafViewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
return resolver;
}
}HomeController.java
@Controller
public class HomeController {
private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
/**

*/
@RequestMapping(value = "/dnr", method = RequestMethod.GET)
public String home(Locale locale, Model model) {
logger.info("Welcome home! The client locale is {}.", locale);
Date date = new Date();
DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG,
DateFormat.LONG, locale);
String formattedDate = dateFormat.format(date);
model.addAttribute("serverTime", formattedDate);
return "home";

model.addObject("title", "Spring Security Hello World");
model.addObject("message", "This is welcome page!");
model.setViewName("hello");
logger.info("Hello");
return model;

我不确定它是否有用，但是您可以通过扩展WebInit而不是实现WebApplicationInitializer来简化WebApplicationInitializer。否则，Thymeleaf配置在我看来是可以的(假设它被称为)。我给出了配置的工作框架，这样你就可以用它进行实验了。
WebApplicationInitializer
public class WebInitializer extends
AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return null;
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] { WebConfig.class };
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}WebConfig
@Configuration
@EnableWebMvc
@ComponentScan("com.kreuzman")
public class WebConfig {
@Bean
public ITemplateResolver templateResolver() {
TemplateResolver resolver = new ServletContextTemplateResolver();
resolver.setPrefix("/templates/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
resolver.setCacheTTLMs(0l);
return resolver;
}
@Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver());
return engine;
}
@Bean
public ViewResolver thymeleafViewResolver() {
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
viewResolver.setCharacterEncoding("UTF-8");
return viewResolver;
}
