"Error starting ApplicationContext" when executing spring application

I got few microservices and two are running great but on the other two I got some errors. The database schema is not created yet but usually it was created once I started the application successfully. I got similar running classes and I already tried few things such as deleting my repository in .m2 folder which didn't worked out.
I am also using eureka discovery service and eureka zuul.
I am not sure but I think it's not able to find the database schema. When I added a #Entity annotation in another but similar project it failed for the first time.
UPDATE
I figured out that I used the same coloumn name twice in a java class. So the first application is running again. But the second one (similar architecture) doesn't run when I am using annotations such as #Entity or #Column. When I delete them everything is working. The error message is the same.
UPDATE 2
I think it's a logical issue between the following two classes. I am two exhausted right now to figure out tho.
package de.leuphana.jee.component.structure;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
#Entity
public class AddressEntity {
private Integer addressId;
private String city;
private String street;
private int zip;
public AddressEntity(String city, String street, int zip)
{
this.city = city;
this.street = street;
this.zip = zip;
}
public AddressEntity() {
}
#Id
#GeneratedValue
public Integer getAddressId() {
return addressId;
}
#Column(name = "city")
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
#Column(name = "street")
public String getStreet() {
return street;
}
public void setStreet(String street) {
this.street = street;
}
#Column(name = "zip")
public int getZip() {
return zip;
}
public void setZip(int zip) {
this.zip = zip;
}
}
package de.leuphana.jee.component.structure;
import java.time.LocalDate;
import java.util.HashSet;
import java.util.Set;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToMany;
#Entity
public class OrderEntity {
private Set<AddressEntity> addresses;
private LocalDate orderDate;
private Integer orderId;
private Set<OrderItemEntity> orderItemsEntitySet;
public OrderEntity(AddressEntity addressEntity, LocalDate orderDate) {
addresses = new HashSet<>();
addresses.add(addressEntity);
this.orderDate = orderDate;
orderItemsEntitySet = new HashSet<>();
}
public OrderEntity() {
}
#Id
#GeneratedValue
public Integer getOrderId() {
return orderId;
}
public void setOrderId(Integer orderId) {
this.orderId = orderId;
}
#OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
public Set<OrderItemEntity> getOrderItemsEntitySet() {
return orderItemsEntitySet;
}
public void setOrderItemsEntitySet(Set<OrderItemEntity> orderItemsEntitySet)
{
this.orderItemsEntitySet = orderItemsEntitySet;
}
public void addOrderItem(OrderItemEntity orderItemEntity) {
orderItemsEntitySet.add(orderItemEntity);
}
#OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
public Set<AddressEntity> getAddresses() {
return addresses;
}
public void setAddresses(Set<AddressEntity> addresses) {
this.addresses = addresses;
}
public void addAddress(AddressEntity addressEntity) {
addresses.add(addressEntity);
}
}
OLD PROBLEM (pom.xml / application.properties are similar in every project)
Java class:
package de.leuphana.jee.component.structure;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.OneToOne;
#Entity
public class CustomerEntity {
// intrinsic attribute
private Integer customerId;
// relational attribute
private CartEntity cartEntity;
#Id
#GeneratedValue
public Integer getCustomerId() {
return customerId;
}
public void setCustomerId(Integer customerId) {
this.customerId = customerId;
}
#OneToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public CartEntity getCartEntity() {
return cartEntity;
}
public void setCartEntity(CartEntity cartEntity) {
this.cartEntity = cartEntity;
}
}

SOLVED THE ISSUE
The issue wasn't logical, at least not the way I expected it. I had no setter method for addressId!
Feeling so stupid right now.
My code wasn't able to set a primary key for AddressEntity

Spring - Issue configuring Hibernate Jpa

I'm moving from a Spring Boot 1.5.9 to a normal Spring project.
In application.properties I've added

The configuration class is based on a course with Spring boot 1.3, here I'm using 1.5.9, I don't get why I'm having this issue.
Edit for customer repeated column
#Entity
public class Customer extends AbstractDomainClass{
private String firstName;
private String lastName;
private String email;
private String phoneNumber;
#Embedded
private Address billingAddress;
#Embedded
private Address shippingAddress;
// getters setters
}
Address class
#Embeddable
public class Address {
private String addressLine1;
private String addressLine2;
private String city;
private String state;
private String zipCode;
// getters setters
}

The issue occurs because you have the following mapping:
#Entity
public class Customer extends AbstractDomainClass {
//other attributes...
#Embedded
private Address billingAddress;
#Embedded
private Address shippingAddress;
}
Here, what Hibernate will try to do is to map the attributes of the #Embedded class in columns of your table. This is, it will map Address#addressLine1 from attribute Address billingAddress to the column addressLine1 in the table customer. Similar will happen with the other fields for attribute billingAddress and for class Address. And then, it will do the same with Address shippingAddress, this is, it will map Address#addressLine1 for shippingAddress to column addressLine1 in table customer. This is the cause of the exception.
Since this is more a design problem rather than an issue in your code, I would suggest some ways to solve it.
Have different columns in your table for all the fields, and map each one to the specific attribute in classes. Here's a basic example:
DDL of your table (using the most common sql I can come up with).
CREATE TABLE customer (
id INT NOT NULL,
billingAddressLine1 VARCHAR(200) NOT NULL,
shippingAddressLine1 VARCHAR(200) NOT NULL,
-- other columns...
PRIMARY KEY(id)
);
Hibernate mapping for #Embedded attributes using #AttributeOverrides:
#Entity
public class Customer extends AbstractDomainClass {
//other attributes...
#Embedded
#AttributeOverrides(
#AttributeOverride(
name = "addressLine1",
column = #Column(name = "billingAddressLine1"),
)
//do similar for the other attributes...
)
private Address billingAddress;
#Embedded
#AttributeOverrides(
#AttributeOverride(
name = "addressLine1",
column = #Column(name = "shippingAddressLine1")
)
//do similar for the other attributes...
)
private Address shippingAddress;
}
Instead of having the columns in the customer table, use a separate table called address and a column called addressType (or the name you prefer) to store addresses for a customer.
DDL of your table (using the most common sql I can come up with).
CREATE TABLE customer (
id INT NOT NULL,
-- other columns...
PRIMARY KEY(id)
);
CREATE TABLE address (
id INT NOT NULL,
addressType INT NOT NULL,
customer_id INT NOT NULL,
addressLine1 VARCHAR(200) NOT NULL,
-- other columns...
PRIMARY KEY(id),

Springboot mvc java application cannot run when it's set to UPDATE

My web application was working until I decided to put in comments. I messed it up a lot so I changed spring.jpa.hibernate.ddl-auto from upate to create-drop
But now, when I spring.jpa.hibernate.ddl-auto = create-drop the application starts and when I change it to spring.jpa.hibernate.ddl-auto = update I get this error:

And then I have a repository for the appropriate Entities. I have heavily edited the code so I won't be a "heresallmycode" guy. But, I'm pretty sure that my annotation relations are the problem. I wanted there to be comments that have a MANY TO ONE relationship with an article, a user that would appear above the comments when they are posted and a reverse ONE TO MANY relationship of the article with the comments. When the tables are created using the create paramater, my articles table was not emptied(I had it on update before), I had to manually drop it. Now, when the table is created it's empty. I thought that was worth mentioning. I can post the create logs If that would be neccessary.
EDIT
I forgot my ArticleController
#Controller
public class ArticleController
{
#Autowired
private ArticleRepository articleRepository;
#Autowired
private UserRepository userRepository;
#Autowired
private CommentRepository commentRepository;
//---------------------------------METHODS-----------------------
//ARTICLE DETAILS--------------------------------------------------
#GetMapping("/article/{id}")
public String details(Model model, #PathVariable Integer id)
{
if (!this.articleRepository.exists(id))
{
return "redirect:/";
}
UserDetails principal = (UserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();//This was inside the IF
if (!(SecurityContextHolder.getContext().getAuthentication() instanceof AnonymousAuthenticationToken))
{
User entityUser = this.userRepository.findByEmail(principal.getUsername());
model.addAttribute("user", entityUser);
}
//Getting the article
Article article = this.articleRepository.findOne(id);
//Comments
Set<Comment> comments = this.commentRepository.findCommentsByArticleId(id);//findAllByArticlesId
//Set<User> commenters = this.userRepository.findAllByComments(comments);
//Models
model.addAttribute("article", article);
//model.addAttribute("commenters", commenters);
model.addAttribute("comments", comments);
model.addAttribute("view", "article/details");
return "base-layout";
}
#PostMapping("/article/{id}")
#PreAuthorize("isAuthenticated()")
public String detailsProcess(#PathVariable Integer id, ArticleBindingModel articleBindingModel)
{
if (!this.articleRepository.exists(id))
{
return "redirect:/";
}
//Getting the article
Article article = this.articleRepository.findOne(id);
//Getting the commenter
UserDetails principal = (UserDetails) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
User commenter = this.userRepository.findByEmail(principal.getUsername());
//Setting the values for the comment section
return "redirect:/article/{id}";
}
}

You have defined the relation to User in Comment as:
#ManyToOne()
#JoinColumn(nullable = false, name = "commenterId")
public User getCommenter()
{
return commenter;
}
but you are referring to comments string column on the Comment side of the relationship. You should change the mappedBy to:
#OneToMany(mappedBy = "commenter")
public Set<Comment> getComments()
{
return comments;
}

SpringBoot Controller error

I'm trying to create Spring Boot "Car rental" application, that will connect with database, so I can use simple operations like GET, POST, etc to test it. I've created 3 tables : Cars, Clients and Rentals (where rentals has foreign keys to client's and car's ids). But this is the error that I'm getting:
2017-06-13 22:22:59.238 ERROR 8044 --- [ main] o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of constructor in eu.fitk.controllers.CarsController required a bean named 'entityManagerFactory' that could not be found.
Action:
Consider defining a bean named 'entityManagerFactory' in your configuration.
and this is how my CarsController class looks like:
#RestController
#RequestMapping("/cars")
public class CarsController {
private final CarsRepository carsRepository;
public CarsController(CarsRepository carsRepository){
this.carsRepository = carsRepository;
}
#RequestMapping(method = RequestMethod.POST)
public void addCar(#RequestBody Cars car){
carsRepository.save(car);
}
#RequestMapping(method = RequestMethod.GET)
public List<Cars> getCars(){
return carsRepository.findAll();
}
}
I tried to add #Autowired annotation above CarsController constructor, but it didn't help, I'm new to Spring Boot and I don't really fully get how it is configurated.

Hibernate doesn't handle annotations added both on fields and on methods very well. Just move all the hibernate annotations either on fields either on methods in your entities.

Use Hibernate reverse engineering concept to generate Java persistent entities from database tables in eclipse

Unknown column error using hibernate OneToMany mapping

I m new to hibernate and having error Unknown column in OneToMany mapping. I m trying to implement the one to many relationships using hibernate but having an error.
Here is my Code:
Department Class:
#Entity
#Table(name="department")
public class Department {
#Id
#Column(name="dept_id")
private int id;
#Column(name="dept_name")
private String name;
#OneToMany(mappedBy="department", cascade=CascadeType.ALL, fetch=FetchType.EAGER)
private Collection<Employee> employees = new ArrayList<Employee>();
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 Collection<Employee> getEmployees() {
return employees;
}
public void setEmployees(Collection<Employee> employees) {
this.employees = employees;
}
}
Employee Class:
#Entity
#Table(name = "employee")
public class Employee {
#Column(name="emp_id")
#Id
private int id;
#Column(name="emp_name")
private String name;
#ManyToOne
private Department department;
public Department getDepartment() {
return department;
}
public void setDepartment(Department department) {
this.department = department;
}
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;
}
}
Employee Dao Class:
public class EmployeeDao {
public void addEmployee(Employee emp, int id){
Department department = new Department();
SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
department = (Department) session.get(Department.class, id);
emp.setDepartment(department);
department.getEmployees().add(emp);
session.save(emp);
session.getTransaction().commit();
session.close();
sessionFactory.close();
}
}
Here is my Database :
CREATE TABLE `department` (
`dept_id` int(11) NOT NULL,
`dept_name` varchar(255) DEFAULT NULL
)
CREATE TABLE `employee` (
`emp_id` int(11) NOT NULL,
`emp_name` varchar(255) DEFAULT NULL,
`dept_id` int(11) DEFAULT NULL
)

Can you please tell me what I'm doing wrong here? :)

Try make so
#ManyToOne
#JoinColumn(name = "dept_id")
private Department department;

The default column name for mapping is of type,
table_name + '_' + target_table_primary_key. This is why it is looking for department_dept_id
You can specify mapping column using annotations. #JoinColumn(name="dept_id").

Property-based access is the right way for using #OneToMany and #ManyToOne annotation
Use #OneToMany like below:
private Collection<Employee> employees;
#OneToMany(mappedBy="department", cascade=CascadeType.ALL, fetch=FetchType.EAGER)
public Collection<Employee> getEmployees() {
return employees;
}
public void setEmployees(Collection<Employee> employees) {
this.employees = employees;
}
And use #ManyToOne like below:
private Department department;
#ManyToOne
#JoinColumn(name = "dept_id")
public Department getDepartment() {
return department;
}
public void setDepartment(Department department) {
this.department = department;
}
Also you need to use an empty constructor in your model classes, as hibernate wants it.
If you use #OnetoMany and #ManyToOne with File-based access then you will get the following error
Initial SessionFactory creation failed.org.hibernate.MappingException: Could not determine type for: java.util.List, for columns: [org.hibernate.mapping.Column(relatedResources)]
