在Struts 2中实现文件上传

    public String[] getUploadFileName() { return this .uploadFileNames; }
    public void setUploadFileName(String[] uploadFileName) { this .uploadFileNames = uploadFileName; }

    public String[] getUploadContentType() { return this .uploadContentTypes; }
    public void setUploadContentType(String[] uploadContentType) { this .uploadContentTypes = uploadContentType; } 清单15 多文件上传数组绑定Action代码片段

如果你想绑定到列表，则应类似：

    private List < File > uploads = new ArrayList < File > ();
    private List < String > uploadFileNames = new ArrayList < String > ();
    private List < String > uploadContentTypes = new ArrayList < String > ();
