那個轉向后的頁面已經有用gb2312的編碼了
可能原因是在java類里面調用了((HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse()).getWriter().write("");
然后再轉向某個頁面,這樣可能導致編碼格式沖突,導致亂碼
可以先給resonse設置下編碼格式,然后在write
HttpServletResponse httpServletResponse = (HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
httpServletResponse.setContentType("text/html; charset=gb2312");
httpServletResponse.setCharacterEncoding("gb2312");
httpServletResponse.getWriter().write("");
這樣應該就可以解決了
