1、文件上传时,报“415 unsupported type”。

解决:使用@ModelAttribute 而不是@RequestBody

测试:

代码语言:javascript复制
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
    xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">

<head>
    <title>Hello World!</title>
    <meta charset="utf-8">
</head>

<body>
    <form method="POST" enctype="multipart/form-data" action="http://127.0.0.1:8888/upload">
        <p>文件1:<input type="text" name="id" /></p>
        <p>文件2:<input type="text" name="name" /></p>
        <p>文件3:<input type="file" name="file" /></p>
        <p><input type="submit" value="上传" /></p>
    </form>
</body>

</html>
代码语言:javascript复制
    @RequestMapping(value = "/upload", method = RequestMethod.POST)
    public String upload(@ModelAttribute FileUpload fileUpload) {
        return "ok";
    }
