Thymeleaf 3 Spring 5 映射加载字符串而不是 HTML

本文介绍了Thymeleaf 3 Spring 5 映射加载字符串而不是 HTML的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试将 Spring 5 和 Thymeleaf 3 配置在一起.我正在 Eclipse 上工作，我使用全新安装"构建并使用springboot:run"运行应用程序.我已经设置了一个控制器和几个模板，但 Thymeleaf 似乎找不到它们，它在浏览器中显示模板名称(例如panda")而不是加载模板本身(panda.html").

I'm trying to configure Spring 5 and Thymeleaf 3 together. I'm working on Eclipse, I build with 'clean install' and run the app with 'springboot:run'. I've setup a controller and a couple of templates but it seems that Thymeleaf cannot find them, in the browser it shows the template name (es. 'panda') instead of loading the template itself ('panda.html').

这是文件夹结构:

在我的控制器中，我有以下映射

In my controller I have the following mapping

@RestController @Controller public class MyController { @Autowired UtentiRepository utentiRepository; @GetMapping("/gab") public String panda(Model model) { return "panda"; } }

这是模板解析器的代码

@Configuration @EnableWebMvc @ComponentScan("it.uniroma3.spring") public class MvcWebConfig implements WebMvcConfigurer { @Autowired private ApplicationContext applicationContext; @Bean public SpringResourceTemplateResolver templateResolver() { SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver(); templateResolver.setApplicationContext(applicationContext); templateResolver.setPrefix("classpath:/templates/"); templateResolver.setSuffix(".html"); return templateResolver; } @Bean public SpringTemplateEngine templateEngine() { SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(templateResolver()); templateEngine.setEnableSpringELCompiler(true); return templateEngine; } @Override public void configureViewResolvers(ViewResolverRegistry registry) { ThymeleafViewResolver resolver = new ThymeleafViewResolver(); resolver.setTemplateEngine(templateEngine()); registry.viewResolver(resolver); } }

这是 pom.xml

推荐答案

@RestController 隐式地将 @ResponseBody 放在您的方法上，这在您的情况下会导致您返回 String 直接传递到 HttpResponse 对象中(而不是被解释为视图名称).

@RestController implicitly puts @ResponseBody on your methods which in your case causes your returned String to be passed directly into the HttpResponse object (instead of being interpreted as a view name).

所以只需删除 MyController 类中的 @RestController.

So just remove @RestController in MyController class.
