SpringMVC重定向和轉發

九. 重定向和轉發

預設return 是轉發 自動拼接字首和字尾

//轉發
@RequestMapping("/testForword")
public String testForword()
{
    return "success";
}      

需要手動重定向

return “redirect:完整路徑”

@RequestMapping("/testRedirect")
public String testRedirect()
{
     //重定向  隻能通路webapp 下的頁面 不能通路 web-inf下面的頁面
    //return "redirect:/WEB-INF/success.jsp";
    
    //重定向 需要加redirect: 已經完整路徑(字首和字尾隻是給轉發用的)
    return "redirect:/reg.jsp";
}      

<!-- 過濾器  設定編碼 -->

@RequestMapping(value="/getMajorList2",produces = "text/html;charset=utf-8")      

URIEncoding="utf-8"

 <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="utf-8" />
設定禁止緩存：

//設定頁面不緩存
response.setContentType("application/json");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
