SpringMVC怎么注入HttpServletResponse

SpringMVC怎么注入HttpServletResponse

在controller方法中可以直接注入：代码如下
@Controller
@RequestMapping("/user")
public class UserController {

@RequestMapping("/queryUser")
public ModelAndView queryUser(HttpServletResponse response)throws Exception{

List userList = userService.getUserBy(null);

ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("userList", userList);
modelAndView.setViewName("queryUser");
return modelAndView;

}

}

这个问题我都回答多次了： 1 注入方式 @autowired private httpservletrespnose respnose; ---------------------------------------- 其他的方式： 2 请求方法中直接获取 @requestmapping("/xx") public string listui(httpservletrespnose respnose){ return "/xx"; } 3、直接写个工具方法 protected httpservletrequest currentrespnose() throws illegalstateexception { servletrequestattributes attrs = (servletrequestattributes) requestcontextholder.getrequestattributes(); if (attrs == null) { throw new illegalstateexception("当前线程中不存在 respnose上下文"); } return attrs.getrespnose(); }
