SpringMVC重定向和转发

九. 重定向和转发

默认return 是转发 自动拼接前缀和后缀

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

需要手动重定向

return “redirect:完整路径”

@RequestMapping("/testRedirect")
public String testRedirect()
{
     //重定向  只能访问webapp 下的页面 不能访问 web-inf下面的页面
    //return "redirect:/WEB-INF/success.jsp";
    
    //重定向 需要加redirect: 已经完整路径(前缀和后缀只是给转发用的)
    return "redirect:/reg.jsp";
}      

<!-- 过滤器  设置编码 -->
<filter>
  <filter-name>CharacterEncodingFilter</filter-name>
  <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  <init-param>
    <param-name>encoding</param-name>
    <param-value>utf-8</param-value>
  </init-param>
    <init-param>
      <param-name>forceResponseEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
</filter>
<filter-mapping>
  <filter-name>CharacterEncodingFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>      

@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" />
设置禁止缓存：

//设置页面不缓存
response.setContentType("application/json");
response.setHeader("Pragma", "No-cache");
response.setHeader("Cache-Control", "no-cache");
