spring - 当前请求不是多部分请求 - Spring MVC

Question

• Spring 3.1.1.RELEASE
• 码头 7.3.0.v20110203
• 公共文件上传 1.2.1
• 公共-io 1.4

我想通过 html 表单上传两个文件，但我总是得到一个多部分请求异常。我google了很多，但没有找到正确的解决方案。

我的控制器：

    public String String(@RequestParam("version") String version, @RequestParam("changeLog") String changeLog,
            @RequestParam("status") String status, @RequestParam("y") MultipartFile y,
            @RequestParam("x") MultipartFile x, @RequestParam("zId") String zId, RedirectAttributes attr) {

        double size = 0.0;
        byte[] xFile = null;
        byte[] yFile = null;
        String downloadUrl = "blub";

        if (!x.isEmpty() && !y.isEmpty()) {
            try {
                xFile = x.getBytes();
                yFile = y.getBytes();
                size = x.getSize() / (1024 * 1024);
            } catch (IOException e) {
            }
            System.out.println("file upload received! Name:[" + version + "] Size:[" + xFile.length + "]");

        zService.saveZ(new Z(changeLog, status, downloadUrl, size, new Date(), yFile, xFile,

Answer 1

尝试添加标题：

@RequestMapping(value=("/uploadpsd"),headers=("content-type=multipart/*"),method=RequestMethod.POST)

Answer 2

您需要将此添加到您的 spring xml

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
</bean>

Answer 3

请确保您在 jspenctype中为 -element 的 -attribute使用正确的引号。form
