retrieve of email and password from MySql databse using springboot - java

I want retrieve user email from MySql database table using spring boot.i used findByEmailAndPassword in controller but it retrieve null value for email.
Here is my Code
controller
package com.example.demo.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import com.example.demo.JPARepository;
import com.example.demo.pojo.regisbean;
#Controller
public class registerController {
regisbean pp;
#RequestMapping(value = "/")
public String mm() {
System.out.println("I am in m1 method");
return "index";
}
#RequestMapping(value = { "/register", "home" })
public String m1() {
System.out.println("I am in mm method");
return "register";
}
#Autowired
JPARepository jpaRepository;
#PostMapping("/register")
public String regis(#ModelAttribute regisbean rb)
{
System.out.println("I m in regis method");
regisbean b=jpaRepository.save(rb);
if(b!=null)
return "index";
else
return "fail";
}
#RequestMapping(value= {"/login1","login2"})
public String m2() {
System.out.println("i m in m2()");
return "login";
}
#PostMapping("/login")
public String login(#ModelAttribute regisbean rx,Model m) {
System.out.println("I am in Login");
regisbean re=jpaRepository.findByEmailAndPassword(rx.getEmail(), rx.getPassword());
if(re!=null)
{
m.addAttribute("email",rx.getEmail());
m.addAttribute("password",rx.getPassword());
System.out.println("yes");
return "loginsuccess";
}
else
{
System.out.println(rx.getEmail());
System.out.println("failed");
return "register";
}
}
}
pojo class
package com.example.demo.pojo;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "pro")
public class regisbean {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int id;
#Column
private String name;
#Column
private String email;
#Column
private String phonenumber;
#Column
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhonenumber() {
return phonenumber;
}
public void setPhonenumber(String phonenumber) {
this.phonenumber = phonenumber;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Repository
package com.example.demo;
import org.springframework.data.repository.CrudRepository;
import com.example.demo.pojo.regisbean;
public interface JPARepository extends CrudRepository<regisbean, Integer> {
public regisbean findByEmailAndPassword(String email,String password);
}

I was able to get your code to work by inserting a row in the table:
INSERT INTO pro (
id
,email
,name
,password
,phonenumber
)
VALUES (
0
,'user#domain.com'
,'Jim'
,'secret'
,'123-123-1234'
)
Then changing:
public String login(#ModelAttribute regisbean rx,Model m) {
to:
public String login(#RequestBody RegisBean rx,Model m) {
and POSTing the following request body to the /login resource:
{
"email": "user#domain.com",
"password": "secret"
}
I didn't have to make any changes to your Repo. I suspect your attempt was failing because RegisBean was never being initialized with any values and so the repo was asked to find a record with a null email and a null password.

Code can not find Getters and Setters; Not a managed type

I am making authorization for a web application. And I an faced witw problem. I can not use Getters and Setters. Namely setActive ans setRole. And I can not create variable UserFromDb.

I tried to use import com.Vova.Restart.Models.User instead import org.springframework.security.core.userdetails.User and this error has gone but i get another problem Not a managed type: class org.springframework.security.core.userdetails.User. I think this is wrong imort. How can i solve it?

In your repository class , is findByEmailAndPassword is available in jparepository, if not use through #query annotation like #query("select usename from userlogin us where us.username =:email") Something like that in your method.
Also if pre defined method is available please check the spelling, seems incorrect. It has double w in it. findByEmailAndPaswword

CrudRepository generated a messed up Sql Request [duplicate]

This question already has answers here:
Spring Boot Hibernate 5 Ignoring #Table and #Column
(2 answers)
Closed 5 years ago.
I try to use CrudRepository on my work. And When the sql request appear on my log, It's just abnormal.
The real table is 'AllDatabase.AllUserInfo' but the generated sql request look like 'all_user_info alluresinf0_', which is unusable.
I have been all over the internet and nobody seems to face my problem (as far as I know). So please somebody tell me if I'm missing some configuration in my project.
I work on Intellij Idea with 'Spring Initializer' with 'Web' , 'JPA' , 'MySQL' selected. These are my code.
here is my Repository
package com.chuchurest.proj.Repository;
import com.chuchurest.proj.Entity.AllUserInfo;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import java.util.List;
/**
* Created by slimshady23 on 6/25/2017 AD.
*/
#Transactional
#Repository
public interface UserRepository extends CrudRepository<AllUserInfo,String> {
}
here is The 'AllUserInfo' Entity
package com.chuchurest.proj.Entity;
import javax.persistence.Entity;
import javax.persistence.Table;
import javax.persistence.Id;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import java.io.Serializable;
/**
* Created by slimshady23 on 6/23/2017 AD.
*/
#Entity
#Table(name = "AllUserInfo")
public class AllUserInfo {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private String Id;
#Column(name="username")
private String Username;
#Column(name="password")
private String Password;
#Column(name="email")
private String Email;
#Column(name="phone")
private String Phone;
#Column(name="rating")
private Integer Rating;
#Column(name="skill")
private Integer Skill;
#Column(name="description")
private String Description;
public String getId() {
return Id;
}
public void setId(String id) {
Id = id;
}
public String getUsername() {
return Username;
}
public void setUsername(String username) {
Username = username;
}
public String getPassword() {
return Password;
}
public void setPassword(String password) {
Password = password;
}
public String getEmail() {
return Email;
}
public void setEmail(String email) {
Email = email;
}
public String getPhone() {
return Phone;
}
public void setPhone(String phone) {
Phone = phone;
}
public Integer getRating() {
return Rating;
}
public void setRating(Integer rating) {
Rating = rating;
}
public Integer getSkill() {
return Skill;
}
public void setSkill(Integer skill) {
Skill = skill;
}
public String getDescription() {
return Description;
}
public void setDescription(String description) {
Description = description;
}
}
And this is how I invoke the save() method
package com.chuchurest.proj.Service;
import com.chuchurest.proj.DAO.UserInfoDAO;
import com.chuchurest.proj.Entity.AllUserInfo;
import com.chuchurest.proj.Repository.UserRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
* Created by slimshady23 on 6/24/2017 AD.
*/
#Service
public class AppService {
#Autowired
private UserRepository userRepository;
public void PerformRegister(AllUserInfo userinfo)
{
userRepository.save(userinfo);
}
}
And here is the Application.properties
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/AllDatabase
spring.datasource.username=root
spring.datasource.password= ******
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.id.new_generator_mappings = false
spring.jpa.properties.hibernate.format_sql = true
spring.jpa.show-sql= true
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE
Note the dot, the difference between schema.tablename and tablename alias
The AllUserInfo_f0 is an alias for AllUserInfo. It's used in Hibernate by default for supporting query relations on the same table multiple times. It doesn't break your sql.
