我可以使用UserRepository将用户/保存到MYSQL数据库,但是当我尝试使用相同的信息/登录时,我会遇到一个错误,我无法弄清楚。
java. sql. sql语法错误异常:SQL语法中有错误;查看与您的MySQL服务器版本对应的手册,了解在第1行"123 !@#"附近使用的正确语法
储存库

package com.repository;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.stereotype.Repository;

import com.entity.User;

@Repository
public interface UserRepository extends JpaRepository<User, String> {

    ///builds successfully but crashes saying sql syntax error, look up manual. Will allow me to save users to db
    @Query(value = "Select S from User S where S.email = ?1 and S.pass  ?2", nativeQuery = true)
    User login( String user, String pass);
    
    //doesnt build correct but is like my other repository
//  @Query("Select S from User S where S.email = ?1 and S.pass  ?2")
//  User login( String user, String pass);
}

用户控制器

package com.controller;

import java.util.List;
import java.util.Optional;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.CrossOrigin;
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.RestController;

import com.entity.Saved;
import com.entity.User;
import com.repository.SavedRepository;
import com.repository.UserRepository;

@CrossOrigin
@RestController
public class UserController {

    @Autowired
    UserRepository userRepository;
    @Autowired
    SavedRepository savedRepository;
    
    //~~~~~~~~~~~~~~~~~~user details group ~~~~~~~~~~~~
    
    //saving user details from new user login page
    @RequestMapping(value = "/save",
            consumes=MediaType.APPLICATION_JSON_VALUE,
            produces=MediaType.APPLICATION_JSON_VALUE,
            method=RequestMethod.POST
            )
    public void submitUserDetails(@RequestBody User user) {
        userRepository.save(user);
    }
    
    //finds user details 
    @RequestMapping(value="/findUser",
            produces=MediaType.APPLICATION_JSON_VALUE,
            method=RequestMethod.GET
            )
    private ResponseEntity<Optional<User>>findUser(String email){
        Optional<User> user = userRepository.findById(email);
        return new ResponseEntity<>(user,HttpStatus.OK);
    }
    
    //user Login details
    @RequestMapping(value="/login",
            produces=MediaType.APPLICATION_JSON_VALUE,
            method=RequestMethod.POST
            )
    public ResponseEntity<User>login(@RequestBody User user){
        User userLogin = userRepository.login(user.getUser(), user.getPass());
        if(userLogin != null) {
            return new ResponseEntity<>(userLogin, HttpStatus.OK);
        }else {
            return new ResponseEntity<>(HttpStatus.UNAUTHORIZED);
        }
    }

我试过使用原生查询和Jpla查询,并将它们参数化。我不确定还能做什么。

您可以选择在SpringDataJPA中创建自定义方法,而不是使用原生查询。

@Repository
public interface UserRepository extends JpaRepository<User, String> {
   User findByEmailAndPass(String email, String password);
}
