    在我最近的spring项目中,我需要从html页面生成一个pdf文件。我正试着用 WkhtmlToPdf 是的。但是我无法从html页面生成pdf文件。我搜索了许多关于 WKHTMLTOPDF格式 但我没有找到答案。我在这里贴代码。 这是我的控制器类,它重定向到带有学生列表的html页面 

    @Controller
public class TestController {

    @Autowired
    StudentService studentService;

    @Autowired
    PdfDemo pdfDemo;

    @GetMapping("/test")
    private String testPage(Model model)
    {    
        List<Student> studentList = studentService.findAll();
        System.out.println(studentList);
       model.addAttribute(studentList);
        return "sample";
    }
}

    这是我的html页面,显示学生列表 

    <body>
<div class="container" id="pdfDiv">
    <h2>HTML Table</h2>
    <table class="table table-striped">
        <tr>
            <th>Id</th>
            <th>Name</th>
            <th>Session</th>
            <th>Department</th>
            <th>Roll</th>
            <th>Mobile</th>
        </tr>
        <tr th:each="student : ${studentList}">
            <td th:text="${student.id}"></td>
            <td th:text="${student.name}"></td>
            <td th:text="${student.session}"></td>
            <td th:text="${student.department}"></td>
            <td th:text="${student.roll}"></td>
            <td th:text="${student.mobile}"></td>
        </tr>
    </table>
</div>
<a href="#" th:href="@{/getStudentsListAsPdf}">Download PDF</a>
</body>

    在这里你可以看到,我有一个链接生成pdf。这个 PdfGenerateController 班级是 

    @Controller
public class PdfGenerateController {

    @GetMapping("/getStudentsListAsPdf")
    public ResponseEntity<Resource> generateReportOfStudent() {

        String downloadFilePath = generatePdfListForStudents();
        System.out.println("DL File Path: "+downloadFilePath);
        if (downloadFilePath == null)
            throw new NullPointerException("data missing");

        if (downloadFilePath == null)
            return ResponseEntity.badRequest()
                    .contentType(MediaType.parseMediaType("application/pdf"))
                    .body(null);

        File file = new File(downloadFilePath);

        Path path = Paths.get(file.getAbsolutePath());
        ByteArrayResource resource = null;
        try {
            resource = new ByteArrayResource(Files.readAllBytes(path));
        } catch (IOException e) {
            e.printStackTrace();
        }

        HttpHeaders headers = new HttpHeaders();
        headers.add("Content-Disposition", "attachment; filename=\"student_list" + ".pdf\"");

        return ResponseEntity.ok()
                .headers(headers)
                .contentLength(file.length())
                .contentType(MediaType.parseMediaType("application/pdf"))
                .body(resource);
    }
}

    这是编写代码生成pdf的类 

    @Service
public class PdfDemo {

    @Value("${file.download.base}")
    private String DOWNLOAD_FOLDER;

    public static final String DOWNLOAD_PATH = "tmp/downloads/";
    public static final String ZIP_PATH = "/tmp/zip_files";
    public static final String FILE_NAME = "student_list";
    public static final String SERVER_REPORT_URL = "/report/html";
    public static final String DOWNLOAD_FILE_PATH = DOWNLOAD_PATH + FILE_NAME;
    public static final String ZIPFILE = "/tmp/zip_files/cmed_report.zip";
    public static final String ZIPFILE_NAME = "cmed_report.zip";
    public static final String SRCDIR = "/tmp/downloads";
    public static final String DATE_FORMAT_PATTERN = "yyyy-MM-dd-HH";

    public static String getBaseURL() throws MalformedURLException {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
                .getRequestAttributes()).getRequest();
        String baseUrl = "";
        if (request != null) {
            // handle proxy forward
            String scheme = request.getScheme();
            if (request.getHeader("x-forwarded-proto") != null) {
                scheme = request.getHeader("x-forwarded-proto");
            }

            Integer serverPort = request.getServerPort();
            if ((serverPort == 80) || (serverPort == 443)) {
                // No need to add the server port for standard HTTP and HTTPS ports, the scheme will help determine it.
                baseUrl = String.format("%s://%s%s", scheme, request.getServerName(), request.getContextPath());
            } else {
                baseUrl = String.format("%s://%s:%d%s", scheme, request.getServerName(), serverPort, request.getContextPath());
            }
        }

        return baseUrl;
    }

    public static String generatePdfListForStudents()
    {
        WkHtmlToPdf pdf = new WkHtmlToPdf();


        try {
            pdf.addSources(Source.fromUrl(getServerAbsolutePath(SERVER_REPORT_URL)));

            System.out.println("Server absolute path: " + getServerAbsolutePath(SERVER_REPORT_URL));
            System.out.println(Source.fromUrl(getServerAbsolutePath(SERVER_REPORT_URL)));

        } catch (Exception e) {
            e.printStackTrace();
        }

        String downloadPath = DOWNLOAD_FILE_PATH + ".pdf";

        pdf.addArguments(
                Argument.from(EnableJavascript));

        System.out.println("PDF Location: " + downloadPath);
        // Save the PDF
        File file = new File(downloadPath);
        System.out.println("Directory status: " + file.exists() + " " + file.isDirectory());

        try {
            System.out.println("Paths.get: " + Paths.get(downloadPath));

            pdf.save(Paths.get(downloadPath));
        } catch (IOException e) {
            e.printStackTrace();
        }
        return downloadPath;
    }

    public static String getServerAbsolutePath(String requestPath) throws MalformedURLException {
        String URL = getBaseURL() + requestPath;
        return URL;
    }
}

    这是 Controller 类 SERVER_REPORT_URL 在里面 PdfDemo 班 

    @Controller
public class HtmlViewReportController {

    @Autowired
    StudentService studentService;


    @GetMapping(value = "/report/html")
    public String getPdfReportForStudent(Model model) {
        model.addAttribute("studentList", studentService.findAll());
        return "sample";
    }
}

    现在,当我偶然发现 Download PDF 在html页面中 error 是的。此处为错误堆栈跟踪

    这里是Github link 是的。如果有人能解决这个问题,那将是非常有帮助的。

    你在你的机器上安装了wkhtmltopf吗?试穿一下 https://wkhtmltopdf.org/downloads.html

    我用一种更简单的方式使用了 

    import com.github.jhonnymertz.wkhtmltopdf.wrapper.Pdf;

    生成pdf看起来更容易,如下所示: 

    @Override
public String save(String url) throws IOException, InterruptedException{
    Pdf pdf = new Pdf();
    pdf.addPageFromUrl(url);
    return mockSaveS3(pdf);
}

private String mockSaveS3(Pdf pdf) throws IOException, InterruptedException{
    File fileTemp = File.createTempFile("pdf-", "");
    File file = pdf.saveAs("apps/" + fileTemp.getName());
    return file.getAbsolutePath();
}

    然后我将url返回到我存储在 apps/ 目录。

    我解决了这个问题。花了很长时间才解决。我在媒体上一步一步写博客。我在这里发布了这个链接。你可以看到这里所有的台阶。我还提供了示例项目的github链接。看 here
