com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'users.user' doesn't exist

I have been trying to make a web application using spring-boot and hibernate but whenever I try to access the MySQL database I get an error saying that there is a table that does not exist.
I am struggling to find the cause of the problem and I really need to move on with my work, can someone please help.
Hibernate: select user0_.id as id1_1_, user0_.email as email2_1_, user0_.group as group3_1_, user0_.key as key4_1_, user0_.occupation as occupati5_1_, user0_.password as password6_1_, user0_.username as username7_1_ from user user0_ where user0_.email=?

I see that problem is with the CountryCode column, but don't understand, what is with it.
Using MySql DB, one table. It's structure:
Main entity:
#Entity
#Table(name="city")
public class City implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name="Name")
private String name;
#Column(name="CountryCode")
private String countryCode;
#Column(name="District")
private String district;
#Column(name="Population")
private int population;
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 getCountryCode() {
return countryCode;
}
public void setCountryCode(String countryCode) {
this.countryCode = countryCode;
}
public String getDistrict() {
return district;
}
public void setDistrict(String district) {
this.district = district;
}
public int getPopulation() {
return population;
}
public void setPopulation(int population) {
this.population = population;
}
public City(String name, String countryCode, String district, int population){
this.name = name;
this.countryCode = countryCode;
this.district = district;
this.population = population;
}
public City(){
}
}
Repository:
#Repository("cityRepository")
public interface CityRepository extends CrudRepository<City, Integer> {
}
Controller:
#RestController
#RequestMapping("/api/demo")
public class DemoController {
#Autowired
#Qualifier("cityRepository")
private CityRepository cityRepository;
#RequestMapping(value = "towns",
method = RequestMethod.GET,
produces = {MimeTypeUtils.APPLICATION_JSON_VALUE},
headers = "Accept=application/json")
public ResponseEntity<Iterable<City>> getTowns() {
Iterable<City> list = cityRepository.findAll();
return new ResponseEntity<Iterable<City>>(list, HttpStatus.OK);
}
}

Thanks to #JB Nizet answer, after I added property: spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl into application.property file, all is working. Thanks.

EDIT: schema

Probably the problem that you have

org.springframework.dao.DataIntegrityViolationException - when saving Objects

I am facing a DataIntegrityViolationException when I want to insert data into my h2 database. There are two entities I am using which are Team and Driver. The Team entity contains a driverList which should store Driver objects in it.
Team Class:
#Entity
public class Team {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
#ElementCollection
#OneToMany(mappedBy = "team", cascade = CascadeType.MERGE)
private List<Driver> driverList = new ArrayList<>();
/** Constructor **/
public Team(Long id, String name, List<Driver> driverList) {
super();
setId(id);
setName(name);
setDriverList(driverList);
}
/** Default - Constructor **/
public Team(){
super();
this.name = null;
this.driverList = null;
}
/** Getters and Setters **/
public List<Driver> getDriverList() {
return driverList;
}
public void setDriverList(List<Driver> driverList) {
this.driverList = Ensurer.notNull(driverList, "driverList");
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = Ensurer.notNull(id, "ID");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = Ensurer.notNull(name,"Name");
}
Driver Class:
#Entity
public class Driver {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private LocalDateTime birthdate;
private String name;
private String nationality;
#ManyToOne(cascade = CascadeType.MERGE)
private Team team;
public Driver() {
super();
this.id = null;
this.name = null;
this.birthdate = null;
this.nationality = null;
this.team = null;
}
public Driver(Long id, String name, LocalDateTime birthdate, String nationality, Team team) {
super();
this.id = Ensurer.notNull(id,"id");
this.name = Ensurer.notNull(name,"name");
this.birthdate = Ensurer.notNull(birthdate,"birthdate");
this.nationality = Ensurer.notNull(nationality,"nationality");
this.team = Ensurer.notNull(team,"team");
}
/** Getters and Setters **/
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = Ensurer.notNull(id, "id");
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = Ensurer.notNull(name, "name");
}
public LocalDateTime getBirthdate() {
return birthdate;
}
public void setBirthdate(LocalDateTime birthdate) {
this.birthdate = Ensurer.notNull(birthdate, "birthdate");
}
public String getNationality() {
return nationality;
}
public void setNationality(String nationality) {
this.nationality = Ensurer.notNull(nationality, "nationality");
}
public Team getTeam() {
return team;
}
public void setTeam(Team team) {
this.team = Ensurer.notNull(team, "team");
}
DriverRepository Interface:
#Repository
public interface DriverRepository extends CrudRepository<Driver, Long> {
}
Create Driver Method in DriverServiceBean:
#Override
public boolean createDriverFrom(String name, LocalDateTime birthDate,
String nationality, Team team) {
Driver Driver = new Driver();
Driver.setName(name);
Driver.setBirthdate(birthDate);
Driver.setNationality(nationality);
Team t = team;
Driver.setTeam(t);
DriverRepository.save(Driver);
return true;
}

I've already tried out changing cascade = CascadeType.MERGE to cascade = CascadeType.ALL but this did not seem to help.
I would appreciate it if someone could help me out!

Unable to create a custom method using findBy prefix in springJPA

I have table entity called topics with columns as:
id
topic_id
title
details
day_posted
username
userImage
how do I created a custom method so that I retrieve the information from above table based on column topic_id
I have table entity/bean class defined:
#Entity
#Table(name = "topics")
public class TopicBean implements Serializable {
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "topic_id")
private String topic_id;
#Column(name = "title")
private String title;
#Column(name = "details")
private String details;
#Column(name = "username")
private String username;
#Column(name = "user_image")
private String user_image;
#Column(name = "day_posted")
private String day_posted;
//getter and setters
}
Interface:
public interface TopicRepository extends JpaRepository<TopicBean, Long> {
TopicBean findByTopic_id(String topic_id);
}
Service Interface:
public interface TopicService {
TopicBean findById(long id);
TopicBean findByName(String name);
void saveTopic(TopicBean topicBean);
void updateTopic(TopicBean topicBean);
TopicBean findByTopic_id(String id);
void deleteTopicById(long id);
List<TopicBean> findAllTopics();
void deleteAllTopics();
public boolean isTopicExist(TopicBean topicBean);
}
ServiceImpl:
#Component
public class TopicServiceImplementation implements TopicService {
#Autowired
private TopicRepository topicRepository;
#Override
public TopicBean findById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public TopicBean findByName(String name) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void saveTopic(TopicBean topicBean) {
topicRepository.save(topicBean);
}
#Override
public void updateTopic(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void deleteTopicById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public List<TopicBean> findAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void deleteAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public boolean isTopicExist(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public TopicBean findByTopic_id(String id) {
return topicRepository.findByTopic_id(id);
}
}
When I run the GET request like this:
#RequestMapping(path = "/get_topic_details", method = RequestMethod.GET)
public ResponseEntity get_topic_details(#RequestParam(value="topic_id") String topic_id) throws Exception {
topicService.findByTopic_id(topic_id);
HttpHeaders headers = new HttpHeaders();
headers.add("success", "topic added");
return new ResponseEntity(headers, HttpStatus.OK);
}
I get error:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'topics': Unsatisfied dependency expressed through field 'topicService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'topicServiceImplementation': Unsatisfied dependency expressed through field 'topicRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'topicRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property topic found for type TopicBean!

What am I doing wrong?

Avoid using underscore in property names, spring doesn't like it and prefers the standard java naming convention.
Your Entity should look like this.
#Entity
#Table(name = "topics")
public class TopicBean implements Serializable {
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "topic_id")
private String topicId;
#Column(name = "title")
private String title;
#Column(name = "details")
private String details;
#Column(name = "username")
private String username;
#Column(name = "user_image")
private String userImage;
#Column(name = "day_posted")
private String dayPosted;
//getter and setters
}
And based on the above property names create your repository and service method.

I had similar issue and removing _ in the variable name worked for me. I think Spring Data ignores _ in variable names. Even from the error its trying to find the property topic instead of topic_id. Remove _ and try, i believe it should work
