我正在为我的网站开发注册页面的后端部分，问题是，当我在邮递员中进行测试时，出现以下错误：

error in postman

并且我在eclipse控制台中也收到此错误：

2020-05-29 17:58:06.226 ERROR 1368 --- [nio-8484-exec-8] o.h.engine.jdbc.spi.SqlExceptionHelper   : ORA-01400: impossible d'insérer NULL dans ("NAWFEL"."ORDO_DEP_UTILISATEUR"."IDENTIFIANT")

我看到错误来自ID，但是正如您在这里看到的那样，我在JSON部分的邮递员中插入了ID：

{
    "id":2,
    "EMPLOI":2,
    "ENTITE":2,
    "LOGIN":"hr",
    "MOTDEPASSE":"hr",
    "NOM":"bougrine",
    "PRENOM":"rachid",
    "STATUT":"br",
    "CREEPAR": 2
}

这是我的代码，用于在我的应用中配置spring安全性：

package com.app.habilitation.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;


@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {


    @Override
    protected void configure (HttpSecurity http) throws Exception {

        http.cors();
        http.csrf().disable();
        http.authorizeRequests().antMatchers("/**").
        fullyAuthenticated().and().httpBasic();
    }


    @Override
    protected void configure (AuthenticationManagerBuilder auth) throws Exception {

        auth.inMemoryAuthentication()
        .withUser("hr")
        .password("{noop}hr").roles("USER");
    }


}

这是我的控制器：

package com.app.habilitation.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

import com.app.habilitation.entity.UserEntity;
import com.app.habilitation.service.UserService;

@SpringBootApplication
@RestController
@CrossOrigin(origins = "*")
public class UserController {

    private UserService userService;

    @Autowired
    public UserController (UserService theuserService) {
        userService=theuserService;
    }


    @GetMapping("/")
    public String login() {
        return "authenticaated succesfully";
    }


    @GetMapping("/getUsers") 
    public String getUsers() {
        return "users";
    }


    @PostMapping("/addUser")
    public UserEntity addUser (@RequestBody UserEntity theUser) {

        System.out.println("test");
        userService.save(theUser);

        return theUser;
    }
}

这是我的刀（我使用jpa）：

package com.app.habilitation.dao;

import org.springframework.data.jpa.repository.JpaRepository;

import com.app.habilitation.entity.UserEntity;

public interface UserDao extends JpaRepository<UserEntity, Integer> {



}

这是我的实体类：

package com.app.habilitation.entity;

    public Integer getIDENTIFIANT() {
        return IDENTIFIANT;
    }

    public void setIDENTIFIANT(Integer iDENTIFIANT) {
        IDENTIFIANT = iDENTIFIANT;
    }

    public Integer getEmploi() {
        return emploi;

    public void setEmploi(Integer emploi) {
        this.emploi = emploi;

    public String getLogin() {
        return login;
    }

    public void setLogin(String login) {
        this.login = login;
    }

    public String getMdp() {
        return mdp;
    }

    public void setMdp(String mdp) {
        this.mdp = mdp;
    }

    public String getNom() {
        return nom;
    }

    public void setNom(String nom) {
        this.nom = nom;

    public String getPrenom() {
        return prenom;
    }

    public void setPrenom(String prenom) {
        this.prenom = prenom;
    }

    public Integer getCreerpar() {
        return creerpar;
    }

    public void setCreerpar(Integer creerpar) {
        this.creerpar = creerpar;
    }

    public Integer getAnnulepar() {
        return annulepar;
    }

    public void setAnnulepar(Integer annulepar) {
        this.annulepar = annulepar;
    }

    public String getStatut() {
        return statut;
    }

    public void setStatut(String statut) {
        this.statut = statut;
    }

    public Date getDateeffet() {
        return dateeffet;
    }

    public void setDateeffet(Date dateeffet) {
        this.dateeffet = dateeffet;
    }

    public Date getDatefin() {
        return datefin;
    }

    public void setDatefin(Date datefin) {
        this.datefin = datefin;
    }

    public Date getCreele() {
        return creele;
    }

    public void setCreele(Date creele) {
        this.creele = creele;
    }

    public String getMotifdedesactivation() {
        return motifdedesactivation;
    }

    public void setMotifdedesactivation(String motifdedesactivation) {
        this.motifdedesactivation = motifdedesactivation;
    }

    public Date getAnnulele() {
        return annulele;
    }

    public void setAnnulele(Date annulele) {
        this.annulele = annulele;
    }

    public UserEntity(Integer iDENTIFIANT, Integer emploi, Integer entite, String login, String mdp, String nom,
            String prenom, Integer creerpar, Integer annulepar, String statut, Date dateeffet, Date datefin,
            Date creele, String motifdedesactivation, Date annulele) {
        IDENTIFIANT = iDENTIFIANT;
        this.emploi = emploi;
        this.entite = entite;
        this.login = login;
        this.mdp = mdp;
        this.nom = nom;
        this.prenom = prenom;
        this.creerpar = creerpar;
        this.annulepar = annulepar;
        this.statut = statut;
        this.dateeffet = dateeffet;
        this.datefin = datefin;
        this.creele = creele;
        this.motifdedesactivation = motifdedesactivation;
        this.annulele = annulele;
    }

    public UserEntity() {
    }

    @Override
    public String toString() {
        return "UserEntity [IDENTIFIANT=" + IDENTIFIANT + ", emploi=" + emploi + ", entite=" + entite + ", login="
                + login + ", mdp=" + mdp + ", nom=" + nom + ", prenom=" + prenom + ", creerpar=" + creerpar
                + ", annulepar=" + annulepar + ", statut=" + statut + ", dateeffet=" + dateeffet + ", datefin="
                + datefin + ", creele=" + creele + ", motifdedesactivation=" + motifdedesactivation + ", annulele="
                + annulele + "]";
    }



}

这是我的服务界面：

package com.app.habilitation.service;

import java.util.List;

import com.app.habilitation.entity.UserEntity;



public interface UserService {




    public void save (UserEntity theUser);


}

这是我的服务接口Impl：

package com.app.habilitation.service;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.app.habilitation.dao.UserDao;
import com.app.habilitation.entity.UserEntity;

@Service
public class UserServiceImpl implements UserService {

    private UserDao userDao;

    @Autowired

    public UserServiceImpl (UserDao theuserDao) {

        userDao = theuserDao;
    }



    @Override
    @Transactional
    public void save(UserEntity theUser) {

        userDao.save(theUser);

    }



}

这是我的application.properties（我将端口8080更改为8484，因为另一个应用程序使用此端口）：

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:XE
spring.datasource.username=nawfel       
spring.datasource.password=hr

spring.jpa.show-sql=true
server.port=8484

这是我在oracle 10g中的表：

答案 0 :(得分：1)

我认为问题是您在实体中告诉id是一个生成的值。这样，在插入过程中，Jpa会删除该值。您必须更改策略，如果要提供ID，则不应将其标记为自动生成。 hth
