springboot中 freemarker和thymeleaf访问本地磁盘上的模板文件

freemarker和thymeleaf都需要分别加入两个configuration类：

• thymeleaf:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.thymeleaf.spring4.SpringTemplateEngine;
import org.thymeleaf.templateresolver.FileTemplateResolver;

import javax.annotation.PostConstruct;

@Configuration
public class config {

    @Autowired
    private SpringTemplateEngine templateEngine;

    @PostConstruct
    public void extension() {
        FileTemplateResolver resolver = new FileTemplateResolver();
        resolver.setPrefix("/Applications/java/templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setOrder(templateEngine.getTemplateResolvers().size());
        resolver.setCacheable(false);

        templateEngine.addTemplateResolver(resolver);
    }
}

• freemarker

import freemarker.cache.FileTemplateLoader;
import freemarker.template.TemplateException;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;
import org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver;

import java.io.File;
import java.io.IOException;

@Configuration
public class MvcConfigurer {

    @Bean
    public ViewResolver viewResolver() {

        FreeMarkerViewResolver resolver = new FreeMarkerViewResolver();

        resolver.setCache(false);

        resolver.setPrefix("");

        resolver.setSuffix(".html");

        resolver.setContentType("text/html; charset=UTF-8");

        return resolver;
    }

    @Bean
    public FreeMarkerConfigurer freemarkerConfig() throws IOException, TemplateException {

        FreeMarkerConfigurer configurer = new FreeMarkerConfigurer() {

            protected void postProcessConfiguration(freemarker.template.Configuration config) throws IOException, TemplateException {

                FileTemplateLoader fileTemplateLoader = new FileTemplateLoader(new File("/Applications/java/templates/"));

                config.setTemplateLoader(fileTemplateLoader);

            }
        };

        configurer.setDefaultEncoding("UTF-8");

        configurer.setPreferFileSystemAccess(false);

        return configurer;
    }

}
