springmvc 全注解 javax.servlet.ServletException: No adapter for hand
controller 层代码
package top.yunduo2018.taskchain.controller;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import top.yunduo2018.taskchain.common.ReturnMessage;
import top.yunduo2018.taskchain.entity.UserInfoEntity;
import top.yunduo2018.taskchain.service.UserInfoService;
@Controller
@Repository(value = "/user/*")
public class UserInfoController {
@Autowired
UserInfoService userInfoservice;
/*
* 访问路径....项目名/user/userLogin
* post请求
* @param UserInfoEntity实体类的数据类型
* return Map
* */
@ResponseBody
@RequestMapping(value="userLogin.do",method = RequestMethod.POST)
public Map userLogin(UserInfoEntity user){
boolean res=userInfoservice.isExistUser(user);
return ReturnMessage.returnMsg("success", res);
}
/*
* 访问路径....项目名/user/userRegister
* post请求
* @param UserInfoEntity实体类的数据类型
* return Map
* */
@ResponseBody
@RequestMapping(value="userRegister.do",method = RequestMethod.POST)
public String userRegister(UserInfoEntity user){
/*boolean res=userInfoservice.register(user);
return ReturnMessage.returnMsg("success", res);*/
return "success";
}
}
tomcat 启动的时候没有报错
http://localhost:80/TaskChain/user/userRegister.do
访问接口的时候
就报以下异常
