Question

当我点击Spring 3.2应用程序的/ calendar URL时，COntroller代码被成功命中，并且视图'calendar'在ModelAndView对象中设置。

我从春天得到一个错误，因为无法解析视图'calendar'，它应该指向/WEB-INF/views/calendar.ftl

春天：3.2 Freemarker：2.3.20

我知道视图名称设置正确，因为错误是无法解析该视图。

我的Java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;

}
}

控制器方法（我很高兴请求正在使用此方法）：

    @RequestMapping(value="/calendar", method=RequestMethod.GET)
public ModelAndView calendarPage(ModelAndView mv){
    mv.setViewName("calendar");
    mv.addObject("events",eventService.getAll());
    return mv;
}

我不认为应用程序的其他区域（例如sitemesh）会妨碍，但如果这有助于诊断，我也会分享。

错误：

对我而言，来自控制器的“日历”似乎没有转换为文件位置'/WEB-INF/views/calendar.ftl'，因此可能是ViewResolver问题。

我的配置是否正确？

EDIT /更新：刚刚注意到，每次刷新页面时，对/ calendar的请求都会发生两次。也许在那里有一些循环参考？

Answer 1

我似乎已修复它...至少我现在正在获取一个来自FTL的页面。

如果有人偶然发现这个问题，我会添加一些注意事项。

所做的更改：

@Bean(name="freemarkerConfig")
public FreeMarkerConfig freeMarkerConfig() {

现在......

@Bean
public FreeMarkerConfigurer freeMarkerConfig() {

注意在返回的类型中添加了“urer”！

我删除了此方法中的几乎所有配置，因此该方法现在只是：

FreeMarkerConfigurer configurer = new FreeMarkerConfigurer();
configurer.setTemplateLoaderPath("/WEB-INF/views/");
return configurer;

在某些时候我会恢复原状。

因为我在此方法中删除了对COnfiguration类的引用，所以我可以重新组织我的导入并在类上使用@Configuration而不是完全限定的spring..Configuration类。

我的Spring 3.2 / Freemarker配置有什么问题？
