Question

我在使用Spring Boot 4以及Thymeleaf web及其邮件时遇到了一些问题。

如果我单独使用Thymeleaf web的Spring Boot 4，它可以毫无问题地工作。当我包含Thymeleaf邮件配置时，问题就开始了



   @Bean
    public ViewResolver viewResolver() {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        return viewResolver;
    }


    @Bean(name ="templateEngine")
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.addTemplateResolver(emailTemplateResolver());
        return templateEngine;
    }

    private TemplateResolver emailTemplateResolver() {
        TemplateResolver templateResolver = new ClassLoaderTemplateResolver();
        templateResolver.setPrefix("/templates/");
        templateResolver.setTemplateMode("HTML5");
        templateResolver.setCharacterEncoding("UTF-8");
        templateResolver.setOrder(1);
        return templateResolver;
    }

如果我尝试构建并运行此页面，则页面无法加载。所以我已经使用包含Web模板更新了代码。



@Bean
    public ViewResolver viewResolver() {
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        return viewResolver;
    }

@Bean(name ="templateEngine")
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(emailTemplateResolver());
    templateEngine.addTemplateResolver(webTemplateResolver());
    return templateEngine;
}

private TemplateResolver emailTemplateResolver() {
    TemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setPrefix("/templates/");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setOrder(1);
    return templateResolver;
}

private TemplateResolver webTemplateResolver() {
    TemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setPrefix("/templates/");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setOrder(2);
    return templateResolver;
}


@Bean(name ="templateEngine")
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.addTemplateResolver(emailTemplateResolver());
    templateEngine.addTemplateResolver(webTemplateResolver());
    return templateEngine;
}

private TemplateResolver emailTemplateResolver() {
    TemplateResolver templateResolver = new ClassLoaderTemplateResolver();
    templateResolver.setPrefix("/templates/");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setOrder(1);
    return templateResolver;
}

private TemplateResolver webTemplateResolver() {
    TemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setPrefix("/templates/");
    templateResolver.setTemplateMode("HTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setOrder(2);
    return templateResolver;
}

这是加载页面时返回的错误：

需要什么配置才能使百褶网和邮件模板都能正确使用弹簧靴？

如果您已添加spring-boot-starter-thymeleaf，则无需任何配置即可正常工作（spring boot会为您带来魔力）

<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

否则，如果您正在寻找配置，只需在类似的配置类中创建bean TemplateResolver即可。

@Bean
public ClassLoaderTemplateResolver emailTemplateResolver() {
    ClassLoaderTemplateResolver emailTemplateResolver = new ClassLoaderTemplateResolver();
    emailTemplateResolver.setSuffix(".html");
    emailTemplateResolver.setTemplateMode("HTML5");
    emailTemplateResolver.setCharacterEncoding("UTF-8");
    emailTemplateResolver.setOrder(1);

    return emailTemplateResolver;
}

然后，您必须在src/main/resources/templates中添加邮件模板。

因此，例如，如果您创建名为mymail.html的模板，则应使用SpringTemplateEngine bean进行处理。将其注入您需要的地方：

@Autowired
public SpringTemplateEngine templateEngine;

然后处理邮件，添加文件模板的名称与.html扩展名并添加为JavaMailSender的文本，如下一个示例所示：

 String body = templateEngine.process("mymail", ctx);
 javamail.setText(body, true);

Spring Boot 4和Thymeleaf网络和邮件一起不起作用
