如果在同一个响应中已经调用了getOutputStream()来获取输出流,并且尝试再次调用getWriter()来获取写入器,就会违反Servlet API的规定,因为此时输出流已经被占用,无法再创建写入器。这会导致抛出IllegalStateException异常,提示“Cannot call getWriter() after getOutputStream()”。

往response里面改数据,然后系统报这个错 此时直接return null即可解决 但是,要想返回相应的页面呢? 可以直接在response里设置返回的页面
请把皕杰报表更新到5.2版本，或者改用5.0的最后更新包。

所以再次调用resp.getWriter().write(compressor!!.compress(servletResponse))就会报错: UT010006: Cannot call getWriter(), getOutputStream() already called 解决办法就是: 在chain.doFilter(req, responseWrapper)之后(注意,必须是之后,之前的话response的状态还是未提交的)添加判断条件: ...
