當我點擊我的Spring 3.2應用程序的日曆URL時，控制器代碼被成功命中，並且在ModelAndView對象中設置了視圖'日曆'。我的Spring 3.2/Freemarker配置有什麼問題？
我得到一個錯誤，從春天有關無法解析View「日曆」，這應該/WEB-INF/views/calendar.ftl
春點：3.2 Freemarker的：2.3.20
我知道視圖名稱設置正確，因爲錯誤是無法解析該視圖。
我的Java的配置：
public class YhjInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.addFilter("Sitemesh", yhj.web.filters.SitemeshFilter.class).addMappingForServletNames(null, false, "/*");
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(MvcConfiguration.class);
ctx.setServletContext(servletContext);
DispatcherServlet springServlet = new DispatcherServlet(ctx);
ServletRegistration.Dynamic servlet = servletContext.addServlet("dispatcher", springServlet);
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
// want to load some data, eg club list for app scope here?
}
}
@ComponentScan(basePackages={"yhj"})
@org.springframework.context.annotation.Configuration
@EnableWebMvc
public class MvcConfiguration extends WebMvcConfigurerAdapter{
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/css/").addResourceLocations("/resources/css/**");
registry.addResourceHandler("/js/").addResourceLocations("/resources/js/**");
registry.addResourceHandler("/img/").addResourceLocations("/resources/img/**");
}
@Bean(name = "viewResolver")
public ViewResolver viewResolver() {
FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();
resolver.setCache(true);
// resolver.setPrefix("");
resolver.setSuffix(".ftl");
return resolver;
}
@Bean(name="freemarkerConfig")
public FreeMarkerConfig freeMarkerConfig() {
Properties props = new Properties();
props.setProperty("number_format","0.##");
props.setProperty("locale","en-GB");
Configuration configuration = new Configuration();
configuration.setDefaultEncoding("UTF-8");
FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
configurer.setFreemarkerSettings(props);
configurer.setConfiguration(configuration);
configurer.setTemplateLoaderPath("/WEB-INF/views/");
return configurer;
}
}
控制方法（我很高興的要求更是創下此方法）：
@RequestMapping(value="/calendar", method=RequestMethod.GET)
public ModelAndView calendarPage(ModelAndView mv){
mv.setViewName("calendar");
mv.addObject("events",eventService.getAll());
return mv;
}
我不認爲應用程序的其他領域（例如sitemesh）正在阻礙，但如果這可能有助於診斷，我也會分享。

要我來說，似乎「日曆」從控制器沒有被轉換爲文件位置「/WEB-INF/views/calendar.ftl」，所以也許一個ViewResolver問題。
我的配置是否正確？
編輯/更新： 只要注意到，每次刷新頁面時，就會出現/日曆的請求發生兩次。那裏可能有一些循環引用？
