Question

我正在尝试使用Thymeleaf和Spring-boot。我已经尝试过我的helloworld控制器，它可以正常工作。但是，当我创建一个新的用户控制器并尝试使用ModelAndView对象时，我得到了这样的模板引擎异常：

2019-07-23 17:35:43.427 ERROR 22272 --- [nio-8080-exec-1] org.thymeleaf.TemplateEngine             : [THYMELEAF][http-nio-8080-exec-1] Exception processing template "/users/list": Error resolving template [/users/list], template might not exist or might not be accessible by any of the configured Template Resolvers

这是我的pom：

这是我的控制人：

@RestController
@RequestMapping("/users")
public class UserController {
    @Autowired
    private UserRepository userRepository;
    @GetMapping
    public ModelAndView list(Model model) {
        model.addAttribute("userList", userRepository.listUsers());
        model.addAttribute("title", "List users");
        return new ModelAndView("users/list", "userModel", model);
    }
}

这是我的html页面list.html：

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org"
      xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<head>
    <meta charset="UTF-8">
    <title>Thymeleaf Demo!</title>
</head>
<body>
<div th:replace="~{fragment/header :: header}"></div>
<div th:replace="~{fragment/footer :: footer}"></div>
</body>
</html>

这是我的项目结构：

有人可以帮助解决此异常吗？

Answer 1

您可以显示项目的配置类吗？ Thymeleaf找不到您的模板。 documentation表示默认情况下会解析为以下路由：“ / WEB-INF / templates /”，要在其他位置进行查找，您需要覆盖它。我通过使用此类ThymeleafViewResolver来实现这一点。

看看这段代码，我告诉spring应用程序根据我的应用程序上下文查看/ templates /文件夹。

@Bean
public ViewResolver htmlViewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine(htmlTemplateResolver()));
    resolver.setContentType("text/html; charset=UTF-8");
    resolver.setCharacterEncoding("UTF-8");
    resolver.setViewNames(new String[] {"*.html"});
    return resolver;
}

private ITemplateResolver htmlTemplateResolver() {
    SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
    resolver.setCharacterEncoding("UTF-8");
    resolver.setPrefix("/templates/");
    resolver.setCacheable(false);
    resolver.setTemplateMode(TemplateMode.HTML);
    return resolver;
}

这或者评论所建议的

templates.users是具有该名称的文件夹，还是在templates文件夹内的users文件夹？

请检查此内容，因为这可能是导致问题的原因。

解决模板[用户/列表]时出错，该模板可能不存在或任何已配置的模板解析器都无法访问
