Spring Boot无法使用Java配置更改Thymeleaf模板目录

Question

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？

默认情况下，thymeleaf模板是从src/main/resources/templates文件夹读取的。Chandu给出了自定义模板位置名称的解决方案。

首先在类路径中添加一个application.properties文件，并将以下所有属性src/main/resources/application.properties放入该文件中。

spring.thymeleaf.check-template=true # Check that the template exists before rendering it.
spring.thymeleaf.check-template-location=true # Check that the templates location exists.
spring.thymeleaf.enabled=true # Enable MVC Thymeleaf view resolution.
spring.thymeleaf.prefix=classpath:/templates/ # Prefix that gets prepended to view names when building a URL.
spring.thymeleaf.suffix=.html # Suffix that gets appended to view names when building a URL.
