是这样的，我写了重载了两个getInputStream方法，当调用不带参数的方法时，运行正常，当调用带参的方法则报 Can not find a java.io.InputStream with the name [inputStream] in
是这样的，我写了重载了两个getInputStream方法，当调用不带参数的方法时，运行正常，当调用带参的方法则报 Can not find a java.io.InputStream with the name [inputStream] in the invocation stack的错误
代码如下：
Struts2配置：
application/vnd.ms-excel
inputStream
filename="user.xlsx"
spring配置
调用代码：
调用带参数的getInputStream，程序报错
public InputStream getInputStream() { System.out.println(userManageService.getInputStream(curPage, pageSize, sortName, sortOrder, searchValue)==null); return userManageService.getInputStream(curPage, pageSize, sortName, sortOrder, searchValue); }
调用不带参数的，则运行正常
public InputStream getInputStream() { System.out.println(userManageService.getInputStream()==null); return userManageService.getInputStream(); }
