在基于Web的Scopes of Spring中使用Thymeleaf处理HTML文件，并将处理后的模板存储为String
我正在尝试使用thymeleaf呈现HTML文件，并将结果HTML内容保存在web-based scopes of Spring String变量中web-based scopes of Spring以便我以后可以使用它来发送电子邮件或将内容转换为pdf。 我已经完成了本网站给出的实现，但它给了我一些我无法弄清楚的错误。 我正在使用春季靴子1.5.12.RELEASE与thymeleaf 3.0.9 n thymeleaf方言2.2.2。 以下是我的实施。 请帮忙。
import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.thymeleaf.TemplateEngine; import org.thymeleaf.context.Context; import org.thymeleaf.templatemode.TemplateMode; import org.thymeleaf.templateresolver.ClassLoaderTemplateResolver; @Controller public class jataController { @GetMapping(value = "/manual-thym") @ResponseBody public void justSample() { Context context = new Context(); String filename = "templates/view/failure"; String html = renderHtml(filename, context); System.out.println("template\n" + html); } private String renderHtml(String filename, Context context) { ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver(); templateResolver.setSuffix(".html"); templateResolver.setTemplateMode(TemplateMode.HTML); templateResolver.setCacheable(false); templateResolver.setOrder(1); templateResolver.setCharacterEncoding("UTF-8"); TemplateEngine templateEngine = new TemplateEngine(); templateEngine.setTemplateResolver(templateResolver); String html = templateEngine.process(filename, context); return html; } }

请参阅下面的更新
配置Thymeleaf时，您应该定义模板引擎和模板解析器，否则在使用自动assembly默认值时。 如果每次创建实例都不是一个好习惯。 这里有一个示例配置：
@Configuration @EnableWebMvc public class ThymeleafConfiguration { @Bean public SpringTemplateEngine templateEngine() { SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(thymeleafTemplateResolver()); return templateEngine; } @Bean public SpringResourceTemplateResolver thymeleafTemplateResolver() { SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver(); templateResolver.setPrefix("/WEB-INF/views/"); templateResolver.setSuffix(".html"); templateResolver.setTemplateMode("HTML5"); return templateResolver; } }
然后，如果你想以编程方式进行实验，你可以自动assembly它们，但是使用百万美元提供html页面的常用流程也是定义视图解析器：
@Bean public ThymeleafViewResolver thymeleafViewResolver() { ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); viewResolver.setTemplateEngine(templateEngine()); return viewResolver; }
有了这些，您可以将控制器编写为：
@Controller public class MyController { @RequestMapping(value = "/test", method = RequestMethod.GET) public String test() { return "yourTemplateName"; } }
可以使用模型属性将参数传递给模板。
更新31/07/2018
遗憾的是，我没有时间完成工作概念certificate，但我认为下面的代码足以显示流程。 如果你运行它并调用localhost:8080/test你应该能够在控制台中看到输出html。 pdf生成可以作为视图解析器添加和/或以编程方式调用，在此示例中使用xhtmlrenderer ; 我没有时间来完成它所以我评论了它，但你可以明白：服务通过自动assembly模板引擎提供html和pdf生成。

@Configuration public class ThymeleafConfiguration { @Bean public SpringTemplateEngine templateEngine() { SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(thymeleafTemplateResolver()); return templateEngine; } @Bean public ClassLoaderTemplateResolver thymeleafTemplateResolver() { ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver(); templateResolver.setPrefix("templates/"); templateResolver.setSuffix(".html"); templateResolver.setTemplateMode("HTML5"); return templateResolver; } }
HelloWorldController.java
@Controller public class HelloWorldController { @Autowired private Html2PdfService pdfService; @GetMapping(path = "/test") public String hello() { Map parameters = new HashMap(); parameters.put("name", "Borat"); System.out.println(pdfService.template2Html("test", parameters)); return "test"; } // @ResponseBody // @GetMapping // public ResponseEntity helloPdf() { // Map parameters = new HashMap(); // parameters.put("name", "Borat"); // pdfService.template2Pdf("test", parameters); // String filePath = "PATH_HERE"; // InputStream inputStream = new FileInputStream(new File(filePath)); // InputStreamResource inputStreamResource = new InputStreamResource(inputStream); // HttpHeaders headers = new HttpHeaders(); // headers.setContentLength(); // return new ResponseEntity(inputStreamResource, headers, HttpStatus.OK); // } }
Html2PdfService.java
@Service public class Html2PdfService { @Autowired private TemplateEngine templateEngine; public OutputStream template2Pdf(String templateName, Map parameters) { // OutputStream outputStream = new BufferedOutputStream(); // IOUtils.copy() // // Context ctx = new Context(); // String processedHtml = templateEngine.process(templateName, ctx); // ITextRenderer renderer = new ITextRenderer(); // renderer.setDocumentFromString(processedHtml); // renderer.layout(); // renderer.createPDF(os, false); // renderer.finishPDF(); return null; } public String template2Html(String templateName, Map parameters) { Context ctx = new Context(); ctx.setVariable("name", "pippo"); String processedHtml = templateEngine.process(templateName, ctx); return processedHtml; } }
Html2pdfApplication.java
@SpringBootApplication public class Html2pdfApplication { public static void main(String[] args) { SpringApplication.run(Html2pdfApplication.class, args); } }
作为附注，如果您计划动态生成pdf并将其作为控制器中的响应提供，我建议使用流而不是字节数组或临时文件。
我正在使用类似的Springboot和Thymeleaf版本，这样的东西在一些项目上对我有用：
import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.thymeleaf.TemplateEngine; import org.thymeleaf.context.Context; @Component public class EmailProcessor { private TemplateEngine htmlTemplateEngine; @Autowired public EmailProcessor(TemplateEngine templateEngine) { this.htmlTemplateEngine = templateEngine; } public String process(User user) { final Context ctx = new Context(); if (user != null) { ctx.setVariable("user", user); } return htmlTemplateEngine.process("emails/template", ctx); } }
电子邮件模板只是一个常规的Thymeleaf模板，位于：
resouces /模板/电子邮件/ template.html
如果TemplateEngine在singleton bean中自动assembly，那么下面提到的代码就完美了。
@Controller public class jataController { @Autowired private TemplateEngine templateEngine; @GetMapping(value = "/manual-thym") @ResponseBody public void justSample() { Context context = new Context(); String filename = "templates/view/generated-ticket.html"; String html = renderHtml(filename, context); System.out.println("template\n" + html); } private String renderHtml(String filename, Context context) { ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver(); templateResolver.setSuffix(".html"); templateResolver.setTemplateMode(TemplateMode.HTML); templateResolver.setCacheable(false); templateResolver.setOrder(1); templateResolver.setCharacterEncoding("UTF-8"); templateEngine.setTemplateResolver(templateResolver); String html = templateEngine.process(filename, context); return html; } }
但是如果TemplateEngine在request范围bean类型上自动assembly，它会产生exception，而thymeleaf会产生内存泄漏。 所以最后有很多热门和尝试，我得到了一个有效的解决方案，感谢@Paizo。 它可能包含一些不好的做法，但这是它的工作原理：
@Controller @Configuration @EnableWebMvc @ApplicationScope public class MyThymeleafConfig { @GetMapping("/view-template") @ResponseBody public void viewTemplates() { Context context = new Context(); context.setVariable("mydata", "this is it"); String html = templateEngine().process("templates/view-to-process.html", context); System.out.println(html); } /* configuration for thymeleaf and template processing */ @Bean public SpringTemplateEngine templateEngine() { SpringTemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(thymeleafTemplateResolver()); return templateEngine; } @Bean public SpringResourceTemplateResolver thymeleafTemplateResolver() { SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver(); templateResolver.setPrefix("classpath:"); templateResolver.setSuffix(".html"); templateResolver.setCacheable(false); templateResolver.setTemplateMode(TemplateMode.HTML); return templateResolver; } @Bean public ThymeleafViewResolver thymeleafViewResolver() { ThymeleafViewResolver viewResolver = new ThymeleafViewResolver(); viewResolver.setTemplateEngine(templateEngine()); return viewResolver; } }
并提供我们需要定义另一个bean的静态资源，如下所示：
@Configuration @EnableWebMvc public class StaticResourceConfig implements WebMvcConfigurer { @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry .addResourceHandler("/**") .addResourceLocations("/static/", "classpath:static/"); } }
在任何论坛上都找不到此解决方案。 但是我会要求任何Spring开发人员为上面的代码提供更好的实现 。
