Jade4J: No such file or directory

问题

I try to implement Jade4J in my Java Spring app. Unfortunately it can't find the template files.

JadeConfig.java

@Configuration
@EnableWebMvc
public class JadeConfig {
    @Bean
    public SpringTemplateLoader templateLoader() {
        SpringTemplateLoader templateLoader = new SpringTemplateLoader();
        templateLoader.setBasePath("classpath:/templates/");
        templateLoader.setEncoding("UTF-8");
        templateLoader.setSuffix(".jade");
        return templateLoader;
    }

    @Bean
    public JadeConfiguration jadeConfiguration() {
        JadeConfiguration configuration = new JadeConfiguration();
        configuration.setCaching(false);
        configuration.setTemplateLoader(templateLoader());
        return configuration;
    }

    @Bean
    public ViewResolver viewResolver() {
        JadeViewResolver viewResolver = new JadeViewResolver();
        viewResolver.setConfiguration(jadeConfiguration());
        return viewResolver;
    }
}

Controller.java

@RestController
@RequestMapping("/users")
public class UserController {
    @GetMapping("/test")
    public static String render() throws JadeCompilerException, IOException {
        List<Book> books = new ArrayList<Book>();
        books.add(new Book("The Hitchhiker's Guide to the Galaxy", 5.70, true));

        Map<String, Object> model = new HashMap<String, Object>();
        model.put("books", books);
        model.put("pageName", "My Bookshelf");

        return Jade4J.render("index", model);
    }
}

All the time it shows the error "(No such file or directory)". Any idea what's the problem here?

答案1

得分: 2

  1. 你应该有一个 @Controller,而不是 @RestController(用于 Json、XML),因为你试图用 Jade 渲染 HTML。
  2. 不要自己调用 Jade4Render,而是返回一个“指向你的模板”的引用。然后 Spring 会为你进行渲染。
  3. 不要将方法设为静态的。

因此,你的代码应该类似于这样(假设在 classpath:/templates/ 中存在名为 index.jade 的文件):

@Controller
@RequestMapping("/users")
public class UserController {

  @GetMapping("/test")
  public String render(Model model) {
   
    // 在这里向模型添加一些内容,例如 model.put("books", books);
    return "index";
  } 
}
英文:
  1. You should have a @Controller, not a @RestController (for Json,XML) as you are trying to render HTML with Jade.
  2. Do not call Jade4Render yourself, but return a reference to your template. Then Spring will do the rendering for you.
  3. Don't make the method static.

So your code should look something like this (provided a file called index.jade in classpath:/templates/ exists)

@Controller
@RequestMapping(&quot;/users&quot;)
public class UserController {

  @GetMapping(&quot;/test&quot;)
  public String render(Model model) {
   
	// add something to the model here, e.g. model.put(&quot;books&quot;, books);
	return index;
  } 
}
