参数类型跟平台默认的明显不一样，平台默认的

1. 
   
2.         public static Map<String, String> uploadImportExcel(InputStream excel, InputStream mapping){
   
3.                 //删除目录下的临时文件
   
4.                 DeleteExcelTempFile();
   
5.                 HashMap<String, String> result = new HashMap<String, String>();
   
6.                 result.put("excel", createFile(excel));
   
7.                 result.put("mapping", createFile(mapping));
   
8.                 return result;
   
9.         }

这里是object,新增test参数后就不是InputStream类型了

jishuang

参数类型是object，java中的要设置为InputStream ,看平台的默认代码

恩，已经改了。
但是没获取到参数呢。这个没执行到
public static void importProcessBeforeUploadImportExcel() {
  System.out.println("p1="+ModelUtils.getRequestContext().getActionContext().getParameter("p1"));
}

确认js中的事件执行了吗

执行了。在这里是有数据的。
        public static Map<String, String> uploadImportExcel(InputStream excel,InputStream mapping,String p1){
                //删除目录下的临时文件
                DeleteExcelTempFile();
                HashMap<String, String> result = new HashMap<String, String>();
                result.put("excel", createFile(excel));
                result.put("mapping", createFile(mapping));
                result.put("p1", p1);
                System.out.println("p11="+p1);
                return result;
        }

如果执行了设置的正确肯定可以获取到

没执行到这里呢。
public static void importProcessBeforeUploadImportExcel() {
  System.out.println("p1="+ModelUtils.getRequestContext().getActionContext().getParameter("p1"));
}
