Spring Boot Project - Issue with writing JPQL (Intellij)

Spring Boot Project - Issue with writing JPQL (Intellij) - java

So I have setup a spring boot project with which I'd like to create some specific queries.
Very simple, I just want to execute a select statement:
public class UserRepositoryCustomImpl implements UserRepositoryCustom {
#PersistenceContext
private EntityManager entityManager;
public User findUserByEmail(String email) {
Query nativeQuery = entityManager.createQuery("select e from User");
nativeQuery.getFirstResult();
return new User();
}
}
In Intellij, when I hover over User it says cannot resolve symbol for User, I've had a google and most of the answers say you need to use the name of the entity, which of course I did:
#Entity(name = "PG_user")
public class User extends AbstractEntity {
#Column
private String email;
#Column
private String password;
public User(){}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Here is my POM also, if this helps:

But the name of your entity is PG_user
#Entity(name = "PG_user")
public class User extends AbstractEntity {
The name attribute defines the name of the entity that you must use for querying.
But I assume you want to set the name of the table.
That would be
#Table(name = "PG_user")
#Entity
public class User extends AbstractEntity {

Im following the Spring MySql data access walkthrough and I keep getting "Unable to determine Dialect without JDBC metadata."

During the walkthrough I have added the specified model, controller and repo. I have added all the required dependencies through spring boot (I beleive) as well as creating the DB through the MySql shell.
The db is the same as the example as well as the basic root user until I can get this to work then will add another user.
Any help would be appreciated as I have had this same issue every single time I have tried to set up a db.
My model
package com.avorion.dndwiki.Model;
import jakarta.persistence.Entity; import jakarta.persistence.GeneratedValue; import jakarta.persistence.GenerationType; import jakarta.persistence.Id;
#Entity // This tells Hibernate to make a table out of this class public class User {
#Id
#GeneratedValue(strategy=GenerationType.AUTO) private Integer id;
private String name;
private String email;
public Integer getId() { return id;
}
public void setId(Integer 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;
} }
My Controller
package com.avorion.dndwiki.Controller;
import com.avorion.dndwiki.Model.User; import com.avorion.dndwiki.Repository.UserRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody;
#Controller // This means that this class is a Controller #RequestMapping(path="/demo") // This means URL's start with /demo (after Application path) public class MainController {
#Autowired // This means to get the bean called userRepository Which is auto-generated by Spring, we will use it to handle the data private UserRepository userRepository;
#PostMapping(path="/add") // Map ONLY POST Requests public #ResponseBody String addNewUser (#RequestParam String name
, #RequestParam String email) {
// #ResponseBody means the returned String is the response, not a view name
// #RequestParam means it is a parameter from the GET or POST request
User n = new User(); n.setName(name); n.setEmail(email); userRepository.save(n); return "Saved";
}
#GetMapping(path="/all") public #ResponseBody Iterable<User> getAllUsers() { This returns a JSON or XML with the users return userRepository.findAll();
} }
My Repo
package com.avorion.dndwiki.Repository;
import com.avorion.dndwiki.Model.User; import org.springframework.data.repository.CrudRepository;
//This will be AUTO IMPLEMENTED by Spring into a Bean called userRepository CRUD refers Create, Read, Update, Delete
public interface UserRepository extends CrudRepository<User, Integer> {
}
My application properties
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/db_example
spring.datasource.username=root#localhost
spring.datasource.password=thisIsntMyActualPassword

I have tried to set up a number of db with diffrent users and naming conventions. I have reset MySql as well as asking other software engineers.

BeanCreationException: Error creating bean with name 'userRepository': Post-processing of merged bean definition failed

I tried to implement this User management template and adapt it to my needs but the Springboot application does not start anymore, I run into this error: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityConfig': Unsatisfied dependency expressed through field 'userService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userServiceImpl': Unsatisfied dependency expressed through field 'userRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Post-processing of merged bean definition failed; nested exception is java.lang.NoClassDefFoundError: javax/persistence/SynchronizationType
I cannot figure what's wrong. Help please?

I think you must remove this dependency from the pom.xml
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.4.Final</version>
</dependency>
Spring Boot 2.1 already has Hibernate dependencies moreover it uses Hibernare v.5 so here could be some problems with Hibernate v.4 furthermore I didn't find such a dependency in the tutorial you are following
UPD
In case of exception
org.springframework.beans.factory.BeanCreationException: Error
creating bean with name 'entityManagerFactory' defined in class path
resource
[org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]:
Invocation of init method failed; nested exception is
javax.persistence.PersistenceException: [PersistenceUnit: default]
Unable to build Hibernate SessionFactory; nested exception is
org.hibernate.cfg.beanvalidation.IntegrationException: Error
activating Bean Validation integration
read this (the newest version of jaxb-api is 2.3.1). As an option I also suggest you try to add a #EnableTransactionManagement to a configuration class
UPD2
I finally have managed to reproduce the exception (
...Error activating Bean Validation integration
) on my environment and figured out the root of the problem. Since you have already added this dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
you should not add any other validation dependencies. So to get rid of the problem you have to remove this:
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>

The root cause for your issue is incorrect dependencies. You can comment out the following dependencies from your pom.xml:
<dependency>

Next you can do a mvn dependency:tree on your project, and see that org.springframework.boot:spring-boot-starter-web:jar:2.1.0.RELEASE pulls in transitively the correct versions of these two components:
org.hibernate.validator:hibernate-validator:jar:6.0.13.Final
javax.validation:validation-api:jar:2.0.1.Final
org.springframework.boot:spring-boot-starter-data-jpa pulls in transitively:
org.hibernate:hibernate-core:jar:5.3.7.Final
Repository operations on the database work fine with this setup.

I was told the problem is that I need an actual mail server running along. I wasn't aware of that. Does that sound like the plausible reason to this crash to you? Any link to a good tutorial on how to setup an email server and link it to a Maven project? I couldn't find any.

The Application class is like this
#SpringBootApplication
public class PrjApplication {
public static void main(String[] args) {
SpringApplication.run(HqApplication.class, args);
}
}
And I have a RestController where I am trying to do some CRUD Operations like this
#RestController("/register")
public class RegisterController {
#Autowired
private UserRepository userRepository;
#GetMapping("/user/{id}")
public User getUser(#Valid #RequestBody Long id){
User user = userRepository.getOne(id);
return user;
}
#PostMapping("/new")
public User saveUser(#Valid #RequestBody String name,#Valid #RequestBody String email,#Valid #RequestBody String password,#Valid #RequestBody String phone){
System.out.println("savginv user");
User user = new User();
user.setEmail(email);
user.setPassword(password);
user.setName(name);
user.setPhone(phone);
userRepository.save(user);
return user;
}
}
I have made an Entity class; User like this
#Entity
#Table(name = "tbl_users")
public class User {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
Long id;
String name, email, password, phone;
public Long getId() {
return 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 getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
}
When I try to save a user by calling the post method using PostMan it gives me 404 not found error.
{
"timestamp": "2018-06-23T06:47:14.086+0000",
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/prj/register/new"
}
I am using JPARepository to perform Database operations.

/prj isn't part of your controller. Either use a POST request without it (i.e., /register/new), or add it to your controller's mapping:
#RestController("/prj/register")
public class RegisterController {
// rest of the code (no pun intended)

Java Spring - 415 Unsupported Media Type

Here is my Controller:
#RestController
public class UserController {
#RequestMapping(value = "/test", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public User someName(#RequestBody User user){
System.out.println(user.toString());
return user;
}
}
User class:
#Entity
#Table(name = "user")
public class User {
#Id #GeneratedValue
#Column(name = "id")
private Integer id;
private String name;
private String secondname;
private String email;
public User() {
}
public User(Integer id, String name, String secondname, String email) {
this.id = id;
this.name = name;
this.secondname = secondname;
this.email = email;
}
public User(String name, String secondname, String email) {
this.name = name;
this.secondname = secondname;
this.email = email;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
#Column(name = "name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Column(name = "secondname")
public String getSecondname() {
return secondname;
}
public void setSecondname(String secondname) {
this.secondname = secondname;
}
#Column(name = "email")
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
#Override
public String toString() {
return new StringBuilder().append(this.name).append(", ").append(this.secondname).append(", ")
.append(this.email).toString();
}
}

When I want to post in in postman:
{
"name": "test",
"secondname": "test",
"email": "test#test.pl"
}
I have an error: 415 Unsupported Media type
More precisely I have: The server refused this request because the request entity is in a format not supported by the requested resource for the requested method.
In postman I choose raw and JSON (application/json). As headers I have written: Content-Type as key and application/json as value.
Somebody have any idea what I'm doing wrong?

You can use the chrome's inspect to see the HTTP header of your postman's request.Check whether the content-Type is corrent.

This is so common in spring. Make your entity serializable.

I can run the DAOTest on eclipse well but with mvn test I get :
org.springframework.beans.factory.BeanCreationEception : Error
creating bean with name 'sessionFactory' defined in class path
resource [application-context.xml] : Invocation of init method failed;
nested exception is java.lang.NoSuchMethodError :
javax.persistence.OneToMany.orphanRemoval<>Z.
Help please !

You have a library conflict. Have you set this up as Hibernate project in Eclipse so that Eclipse added necessary JARs to the classpath? This would explain why it works in Eclipse but not in the Maven build.
Anyway, ensure the Hibernate library versions match e.g 4.1.8.Final and remove the javax.persistence-api dependency.
This all you should need in your POM regarding Hibernate. Everything else will be resolved transitively by Maven.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>${hibernate.version}</version>
</dependency>
