1：正确写法
@RequestMapping("{type_key}.html")
public String geren(Model model, @PathVariable String type_key) {
List<EmployeeModel> emplist = employeeService.selectOnjobEmployee();
model.addAttribute("type_key", type_key);
model.addAttribute("emplist", emplist);
return "/front/e/aaa";
}
2：正确写法
@RequestMapping("/ama")
public ModelAndView lists(ModelAndView mv) {//import org.springframework.web.servlet.ModelAndView;
mv.setViewName("/back/b");
return mv;
}
import org.springframework.web.portlet.ModelAndView;跳转无效
引包时候一定注意了是servlet不是portlet
