Spring Boot 4和Thymeleaf web和mail一起不工作

Question

我在使用SpringBoot4和ThymeleafWeb及其邮件时遇到了一些问题。

如果我将SpringBoot4单独与Thymeleaf web一起使用，它将能够正常工作，而不会出现任何问题。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;
    }

如果我尝试用它构建和运行，页面将无法加载。因此，我更新了包含web模板的代码。

@Bean公共ViewResolver ViewResolver（）{ThymileAfViewResolver ViewResolver=new ThymileAfViewResolver（）；ViewResolver.setTemplateEngine（templateEngine（））；返回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;
}
这是加载页面时返回的错误：


    2016-10-14 14:56:57.137 ERROR 3875 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateInputException: Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers] with root cause

    org.thymeleaf.exceptions.TemplateInputException: Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

需要什么配置才能在spring boot中正确使用thymeleaf web和邮件模板？

如果你已经添加了sping-boot-starter-thymeleaf应该可以在没有任何配置的情况下工作（sping-boot-starter-thymeleaf对你来说很神奇）

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

否则，如果您正在寻找configurae，那么在一个配置类中创建beanTemplateResolver就可以了。

@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/tem板中添加您的邮件模板。

因此，例如，如果您创建了一个名为mymail.html的模板，您应该使用SpringTemplateEngine bean进行处理。在需要的地方注射：

@Autowired
public SpringTemplateEngine templateEngine;

然后处理邮件，添加文件模板的名称wihtout. html扩展名，并将其作为文本添加到您的JavaMailSender中，如下例所示：

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