我是 Spring 5 和 Spring Boot 的新手。我正在尝试使用 thymeleaf 创建一个 spring 5/spring boot 应用程序。我想制造一场战争,而不是使用带有 Spring Boot 的嵌入式 Web 服务器。
当我部署我的战争时,我的应用程序启动并且我可以访问 src/main/resources/static/ 中的测试 html 页面,其中包含调用我的控制器的 javascript。我可以在这些页面上执行到我的控制器和数据库的往返。
但是,当我尝试打开位于 src/main/resources/templates/testtemplate.html 的 thymeleaf 页面时,我得到了 404

应用:
@SpringBootApplication(exclude = {HibernateJpaAutoConfiguration.class, DataSourceAutoConfiguration.class})
public class WarApplication extends SpringBootServletInitializer
{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application)
{
return application.sources(WarApplication.class);
}
public static void main(String[] args) throws Exception
{
SpringApplication.run(WarApplication.class, args);
}
@Override
public void onStartup(ServletContext servletContext) throws ServletException
{
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(DataServiceConfig.class);
servletContext.addListener(new ContextLoaderListener(rootContext));
AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
dispatcherContext.register(WebConfig.class);
ServletRegistration.Dynamic dispatcher = servletContext.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
网络配置:
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.myproject")
public class WebConfig implements WebMvcConfigurer
{
@Autowired
ApplicationContext ctx;
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry)
{
registry.addResourceHandler("/**").addResourceLocations("classpath:/static/");
}
@Bean
@Description("Thymeleaf Template Resolver")
public SpringResourceTemplateResolver templateResolver()
{
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver ();
templateResolver.setPrefix("/templates/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
return templateResolver;
}
@Bean
@Description("Thymeleaf Template Engine")
public SpringTemplateEngine templateEngine()
{
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
templateEngine.setEnableSpringELCompiler(true);
templateEngine.setTemplateEngineMessageSource(messageSource());
return templateEngine;
}
@Bean
@Description("Thymeleaf View Resolver")
public ThymeleafViewResolver viewResolver()
{
ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
viewResolver.setTemplateEngine(templateEngine());
viewResolver.setOrder(1);
return viewResolver;
}
@Bean
@Description("Spring Message Resolver")
public ResourceBundleMessageSource messageSource()
{
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages");
return messageSource;
}
在 Web 配置中,如果我删除 addResourceHandlers 方法,它不会改变任何内容。我仍然可以在 localhost:8080/ 找到我的静态页面。我尝试将这一行添加到它: registry.addResourceHandler("/**").addResourceLocations("classpath:/templates/");
当我这样做时,我可以在 localhost:8080/mytemplate.html 访问 thymeleaf 模板。但是,它显示为静态页面。片段不翻译。“th”标签似乎被忽略了。
我还尝试从我的 webconfig 中删除 templateResolver、viewResolver 和 templateEngine bean,因为我认为我可能正在覆盖一些自动配置。这没有任何效果。
我相信我的目录结构是相当标准的:
src/main/
/java/com/myproject/[code here]
/resources/static[web pages here]
/resources/templates[thymeleaf pages here]
我错过了什么?
我是现代春天的新手。所以我可能会做一些愚蠢的事情。springboot 中的所有这些自动配置都非常令人沮丧,因为我不知道如何调试它在做什么。
