Question

您好我想将默认的 thymeleaf 配置覆盖到网络应用的自定义文件夹。 Thymeleaf依赖项被添加到pom.xml文件中。我想映射到WEB-INF/views/文件夹。

我当前的配置

@Bean
public ThymeleafViewResolver thymeleafViewResolver() {
    ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();
    thymeleafViewResolver.setTemplateEngine(templateEngine());
    thymeleafViewResolver.setOrder(1);
    return thymeleafViewResolver;
}

@Bean
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());
    templateEngine.addDialect(new LayoutDialect());
    return templateEngine;
}

@Bean
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setPrefix("/WEB-INF/views/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setOrder(1);
    templateResolver.setCacheable(false);
    return templateResolver;
}

当我运行该应用时，它会显示以下异常。

我认为最简单的方法是将spring.thymeleaf.prefix定义为"/WEB-INF/templates/"。否则，请确保您的Bean名称为defaultTemplateResolver。

未经测试 - 但希望有帮助。请提供反馈，以便进一步的读者知道它是否有用。

这很可能是您在IDE中设置项目配置的方式。

检查IDE中的项目设置，确保它们指向正确的位置，并且未发现任何已识别的问题。
