java - Spring Boot 无法使用 Java 配置更改 Thymeleaf 模板目录

Question

将 Thymeleaf 模板文件放置在默认的 src/main/resources/templates 中对我来说效果很好。当我想将目录重命名为 mytemplates 时；它不起作用。

我收到无法找到模板位置:类路径:/templates/(请添加一些模板或检查您的 Thymeleaf 配置)警告应用程序启动。

当我指向主页时，我得到org.thymeleaf.exceptions.TemplateInputException:解析模板“索引”时出错，模板可能不存在或可能无法被任何配置的模板解析器访问 错误。

我使用以下 Java 配置:

package com.zetcode.conf;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Description;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.thymeleaf.spring4.SpringTemplateEngine;
import org.thymeleaf.spring4.view.ThymeleafViewResolver;
import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver;

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Bean
    @Description("Thymeleaf template resolver serving HTML 5")
    public ClassLoaderTemplateResolver templateResolver() {

        ClassLoaderTemplateResolver tres = new ClassLoaderTemplateResolver();

        tres.setPrefix("classpath:/mytemplates/");
        tres.setSuffix(".html");        
        tres.setCacheable(false);
        tres.setTemplateMode("HTML5");
        tres.setCharacterEncoding("UTF-8");

        return tres;
    }

    @Bean
    @Description("Thymeleaf template engine with Spring integration")
    public SpringTemplateEngine templateEngine() {

        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());

        return templateEngine;
    }

    @Bean
    @Description("Thymeleaf view resolver")
    public ViewResolver viewResolver() {

        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();

        viewResolver.setTemplateEngine(templateEngine());
        viewResolver.setCharacterEncoding("UTF-8");
        viewResolver.setCache(false);
        viewResolver.setOrder(1);

        return viewResolver;
    }    

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
    }
}

我做错了什么？

尝试以下操作:

第一个:在 application.properties 文件中定义以下设置

spring.thymeleaf.templateResolverOrder=1

现在自定义您的实现。

@Bean
public ClassLoaderTemplateResolver yourTemplateResolver() {
    ClassLoaderTemplateResolver yourTemplateResolver = new ClassLoaderTemplateResolver();
    yourTemplateResolver.setPrefix("yourTemplates/");
    yourTemplateResolver.setSuffix(".html");
    yourTemplateResolver.setTemplateMode(TemplateMode.HTML);
    yourTemplateResolver.setCharacterEncoding("UTF-8");
    yourTemplateResolver.setOrder(0);  // this is iportant. This way spring 
                                       //boot will listen to both places 0 
                                       //and 1
    emailTemplateResolver.setCheckExistence(true);

    return yourTemplateResolver;
}
