控制器方法：
@RequestMapping(value = "/master/importUser", method = RequestMethod.GET)
public String getManageUser(ModelMap modelMap, HttpServletRequest request,HttpSession session) {
String redirect ="/common/importUser";
try {
if (isSME) {
ResponseEntity<ResponseBean> response =smeService.getSMEUser();
} catch (Exception ex) {
exceptionHandlerService.writeLog(ex);
}
return redirect;
}
服务方式：
这就是我发送回复的方式：
@ResponseBody
@RequestMapping(value="/master/getSMEemployeeList", method = { RequestMethod.GET })
public ResponseBean getEmployeeForSME(){
return sohamRestService.getSMEEmployee();
}
您可能在课堂上通过控制器使用了
@Controller最简单的方法是将
@Controller@RestController或者您可以使用文本/html 到 ResponseBean 的转换器，参见例如这里：https://www.baeldung.com/spring-httpmessageconverter-rest
如需更详细的答案，请使用完整的类更新您的问题（但请随意省略未使用的方法）。
除此之外，请以后正确格式化您的问题。不幸的是，你的问题很难读！请参阅此处：https://stackoverflow.com/editing-help
