你是地址后面的参数吗 ?

比如这样 href="xxxxxxxx?a=x&b=y"

Controller中这么接收就行

public ModelAndView handleRequest(HttpServletRequest req) throws Exception {
ModelAndView mv = new ModelAndView();
mv.addObject("x", req.getParameter("x"));//req.getParameter("key1")是取得key1的值
mv.addObject("y", req.getParameter("y"));
mv.setViewName("login/login.jsp");
return mv;
}
如果不对请告诉我 谢啦

不是应该用@requestMappering和@Controller写的吗

@Controller
@RequestMapping(value = "/login")
public class LoginController {
    @RequestMapping(value = "save", method = RequestMethod.GET)
    public string save(String userName, String password) {
  // 你的逻辑  
}
}

@RequestMapping(value="/goto/entry/{flowType}", method = { RequestMethod.GET })

public String gotoApplyPage(Model model, String appExpressApplyId, @PathVariable("flowType") ExpressFlowTypeEnum flowType) {

setApplyPageModleProperties(model);

switch (flowType) {

case NEW_CUSTOMER_APPLY:

model.addAttribute("ExpressLoanProducts", BusinessType.values());

model.addAttribute("applyDetail", appPreReviewApiImpl.getExpressFirstTrialDTO4Entry(appExpressApplyId));

return "page/express/apply/newCustomerApply";

case RENEW_APPLY:

model.addAttribute("ExpressLoanProducts", BusinessType.values());

model.addAttribute("applyDetail", appPreReviewApiImpl.getExpressFirstTrialDTO4Renew(appExpressApplyId));

model.addAttribute("title", "续签");

return "page/express/apply/renewApply";

default:

throw WebException.instance("不支持的流程类型");

}

}

 

 

 

 

@RequestMapping(value = "/getContractDate", method = { RequestMethod.POST })

@ResponseBody

public ObjectResult<?> getContractDate(String companyId) {

try {

return ObjectResult.success("获取合同期限成功", expressContractApiImpl.getExpressContractByCustomerId(companyId));

} catch (Exception e) {

return FrontExceptionHandler.handleObjectResultException(e);

}

}

 

 

一个get  一个post  项目里copy的,将就着看吧
