使用Html映射API的模糊性

Question

我有这样的API

@RequestMapping(value = "api/Download", method = RequestMethod.POST)
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    String filename = "aman1234.xlsx";
    String filepath = "/home/aman/aman1/";
    response.setContentType("APPLICATION/OCTET-STREAM");
    response.setHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
    FileInputStream fileInputStream = new FileInputStream(filepath + filename);
    int i;
    while ((i = fileInputStream.read()) != -1) {
        out.write(i);
    }
    fileInputStream.close();
    out.close();
}

我正在使用此

调用此API

<form action="api/Download" method="post">

我第一次使用它时工作正常，网址显示http://localhost:8080/UploadExcel/api/Download并且一切正常但在重新定向到此页面并发布表单后，网址映射到http://localhost:8080/UploadExcel/api/api/Upload为什么会这样＆＃ 34; / API＆＃34;添加到URL。当我删除＆＃34; / api＆＃34;从方法和html元素中，一切都完全正常。
