Spring启动使用Thymeleaf作为模板发送电子邮件 - 配置不起作用

我在基于Spring Boot（最新的1.1.5.RELEASE）和Thymeleaf的WebApp工作 .
现在我想添加发送电子邮件的功能，并使用Thymelaf作为模板引擎 .

在pom.xml中我添加：

<dependency>
    <groupId>org.springframework.integration</groupId>
    <artifactId>spring-integration-mail</artifactId>
</dependency>

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.7</version>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

遵循本教程：http://www.thymeleaf.org/doc/articles/springmail.html
得到完整的（没有XML）Java配置：

@Configuration
public ThymeleafReplaceConfigurator {
  @Bean 
   public JavaMailSender getJavaMailSenderImpl(){
        JavaMailSenderImpl javaMailSender = new JavaMailSenderImpl();

        Properties props = new Properties();
        /* some properties here */

        javaMailSender.setJavaMailProperties(props);

    return javaMailSender;
    }

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

        return emailTemplateResolver;
    }

    @Bean
    public ServletContextTemplateResolver defaultWebTemplateResolver(){
        ServletContextTemplateResolver webTemplateResolver = new ServletContextTemplateResolver();
        webTemplateResolver.setPrefix("/templates/");
        webTemplateResolver.setSuffix(".html");
        webTemplateResolver.setTemplateMode("HTML5");
        webTemplateResolver.setCharacterEncoding("UTF-8");
        webTemplateResolver.setOrder(2);

        return webTemplateResolver;
    }

    @Bean
    public SpringTemplateEngine templateEngine(){
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(emailTemplateResolver());
    templateEngine.setTemplateResolver(defaultWebTemplateResolver());
    return templateEngine;
    }

    @Bean
    public ThymeleafViewResolver thymeleafViewResolver() {
        ThymeleafViewResolver thymeleafViewResolver = new ThymeleafViewResolver();

        thymeleafViewResolver.setTemplateEngine(templateEngine());
        thymeleafViewResolver.setCharacterEncoding("UTF-8");

        return thymeleafViewResolver;
    }
}

文件夹和文件树如下：

src
  main
    resources
      templates
        login.html
        error.html
      mails
        exampleMail.html

但它不起作用 . 应用程序正确启动但访问页面（没有此配置工作）会导致异常，例如：

请求处理失败;嵌套异常是org.thymeleaf.exceptions.TemplateInputException：解析模板错误"login"，模板可能不存在或任何已配置的模板解析器可能无法访问

我试图将不同的前缀放入webTemplateResolver.setPrefix但没有成功 .
此外，我注意到在早期版本的Thymeleaf中报告的错误导致了但看起来它已修复，我有更新的版本 .

Does anyone see the misteake in this configuration?
