I have been working on an application that uses Spring boot + MySQL Community Server as database.
My issue is if i use compound names like offeredServices i get this error on my browser:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
Fri Aug 04 21:15:23 EEST 2017
There was an unexpected error (type=Internal Server Error, status=500).
could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
data.sql
INSERT INTO test(name, offeredServices) VALUES
('Test 1','Test 1'),
('Test 2','Test 2');
DROP DATABASE IF EXISTS v;
CREATE DATABASE v;
USE v;
CREATE TABLE test (
id INT PRIMARY KEY auto_increment,
name VARCHAR(40),
serviceDescription VARCHAR(40)
);
But if i use short/simple name like nnnn it works
DROP DATABASE IF EXISTS v;
CREATE DATABASE v;
USE v;
CREATE TABLE test (
id INT PRIMARY KEY auto_increment,
name VARCHAR(40),
nnnn VARCHAR(40)
);
INSERT INTO test(name, nnnn) VALUES
('Test 1','Test 1'),
('Test 2','Test 2');
From my class in java:
#Entity
#Table(name = "test")
public class Test {
private int id;
private String nnnn;
public String getNnnn() {
return nnnn;
}
public void setNnnn(String nnnn) {
this.nnnn = nnnn;}
#Entity
#Table(name = "test")
public class Test {
private int id;
private String offeredServices;
public String getOfferedServices() {
return offeredServices;
}
public void setOfferedServices(String offeredServices) {
this.offeredServices = offeredServices;}

I am not much with:
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
Because it ignore my initial values.
Using spring.jpa.hibernate.ddl-auto=update gives the following error.
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
SQLGrammarException is an exception related to sql syntax errors, but it doesn't give to much information of the root cause.
I was trying to replicate the same error using the same attribute names and table names and I found this:
The Test table creation script is not related to the Test Java entity definition. There is a mismatch because test table create has a field called serviceDescription VARCHAR(40) but in the Test java class there is a totally diferent attribute name called offeredServices.
The create table script has a field called name VARCHAR(40) but in the Test Java entity definition there is no name attribute.
Now lets assume that we have both components related the Database Table and the Java Entity Class.
like this
Create Test table
DROP DATABASE IF EXISTS v;
CREATE DATABASE v CHARACTER SET utf8 COLLATE utf8_bin;
USE v;
CREATE TABLE test (
id INT PRIMARY KEY auto_increment,
name VARCHAR(40),
offeredServices VARCHAR(40)
);
Test java class
#Entity
#Table(name = "test")
public class Test {
#Id
#GeneratedValue
private int id;
private String name;
private String offeredServices;
public String getOfferedServices() {
return offeredServices;
}
public void setOfferedServices(String offeredServices) {
this.offeredServices = offeredServices;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
data.sql
INSERT INTO test(name, offeredServices) VALUES
('Test 1','Test 1'),
('Test 2','Test 2');
Test repository
public interface TestRepository extends JpaRepository<Test,Integer> {}
Spring Boot Class
#SpringBootApplication
public class MysqlerrordemoApplication {
public static void main(String[] args) {
SpringApplication.run(MysqlerrordemoApplication.class, args);
}
#Bean
public CommandLineRunner runner( TestRepository testRepository){
return (args) -> {
testRepository.findAll().forEach(System.out::println);
};
}
}
When I run the application I have got the following error:
SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'test0_.service_description' in 'field list'
This exception means that hibernate is converting the offeredServices attribute name (from camelCase) to offered_services column name (to SNAKE_CASE) because hibernate is using SpringNamingStrategy to generate table and column names.
To solve the problem just add a #Column(name="offeredservices") annotation to the offeredServices attribute. The #Column(name="offeredservices") annotation tells to hibernate that dont try to convert the camelCase attribute name to SNAKE_CASE, just keep column name in lowercase.
This is the final version of Test java class.
#Entity
#Table(name = "test")
public class Test {
#Id
#GeneratedValue
private int id;
private String name;
#Column(name="offeredservices")
private String offeredServices;
public String getOfferedServices() {
return offeredServices;
}
public void setOfferedServices(String offeredServices) {
this.offeredServices = offeredServices;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
To get a very clear answer about this go to the this post spring-boot-jpa-column-name-annotation-ignored
Please also keep the spring.jpa.hibernate.ddl-auto property to create-drop
spring.jpa.hibernate.ddl-auto=create-drop

I am attempting to create a simple existsBy query in a JPA repository using Spring Boot Data JPA. I am getting an error when Spring tries to create the method at runtime. existsBy seems to be the only type of query it is having trouble with. It can create findBy queries just fine. All Spring Boot dependencies in my application are using version 1.5.10.RELEASE.
Here I have a simple User class that uses an #IdClass for a composite primary key.
#Entity
#Table(name = "MASTER_USER")
#IdClass(UserPK.class)
public class User {
#Id
#Column(name = "USER_ID")
private String userId;
#Id
#Column(name = "TOS_ID")
private String tosId;
private boolean isCool;
// getters and setters
}
public class UserPk implements Serializable {
#Id
#Column(name = "USER_ID")
private String userId;
#Id
#Column(name = "TOS_ID")
private String tosId;
// getters and setters
}
Then in my User repository I want an existsByIsCool method to return true if there are any cool users.
#Repository
public interface UserRepository extends JpaRepository<User, UserPK> {
...
boolean existsByIsCool(boolean isCool);
}
Everything compiles fine, but I get the following error when running the application. Just for some stack trace context, this is inside of a Spring REST API that uses Spring Security.

Now, if I remove the composite primary key #IdClass and only use a single field as the #Id, then everything works fine, no issues creating the method.
Edit
I've tracked this down to a bug report. If you are experiencing this issue, please vote on it here

I've searched a lot but I couldn't find a way to solve my problem.
Your issue is here: org.hibernate.AnnotationException: Unknown Id.generator: Product_Sequence
Specifically when you look at your entity class these annotations:
#Id
#GeneratedValue(strategy=GenerationType.SEQUENCE, generator = "Product_Sequence") // <-- Product_Sequence
#SequenceGenerator(name = "product_Sequence", sequenceName = "PRODUCT_SEQ") // <-- Spelt different than above
private Long id;
As #Patrick stated, you're either missing the generator in your database or you have a typo in either the db or your code.
Now, you've indicated you want the auto DDL options to work so everything is managed via code. But what I don't see is your application.properties file specifying a driver class: spring.datasource.driver.class=oracle.jdbc.driver.OracleDriver
I suspect that either its the typo above, or hibernate is not recognizing oracle as it has no knowledge of the driver to use. Have you added the oracle jar to your project library?
Take a look at DZone's article on spring boot, jpa, hibernate and oracle for a tutorial you can follow.
I started my Spring studies by developing a small CRUD, I was able to do the
application to create the tables in the database, insert data and retrieve data.
However, when trying to create relationships between two tables, I'm having an error:
2018-03-18 09:45:19.536 WARN 1036 --- [ main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory
This is my Product.java file:
package app;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
#Entity(name = "wfs_product")
public class Product {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private String name;
private String externalId;
private ProductCategory productCategory;
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 getExternalId() {
return externalId;
}
public void setExternalId(String externalId) {
this.externalId = externalId;
}
#ManyToOne
#JoinColumn(name = "product_category_id")
public ProductCategory getProductCategory() {
return productCategory;
}
public void setProductCategory (ProductCategory productCategory) {
this.productCategory = productCategory;
}
}
And This is my ProductCategory.java file:
package app;
import java.util.Set;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.CascadeType;
#Entity(name = "wfs_product_category")
public class ProductCategory {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
private Integer id;
private Set<Product> products;
private String name;
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
#OneToMany(mappedBy = "productCategory", cascade = CascadeType.ALL)
public Set<Product> getProducts() {
return products;
}
public void setProducts(Set<Product> products) {
this.products = products;
}
}
And this is my application.properties file:
spring.jpa.hibernate.ddl-auto=create
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/sistema
spring.datasource.username=myuser
spring.datasource.password=mypassword

You are mixing field-based access with property-based access. Have a look at this post.
I have a small problem. I'm trying to write a small Spring Boot Application and use Hibernate. This works as well as well, unfortunately I get the above mentioned error message when building <mvn clean package>. The error does not occur until the tests are started. Actually, it's also logical, Hibernate or JUnit tries to use 0000-00-00 00:00:00 as the test date. MySQL does not allow that. how can i tell the test to say `Now ()?
The Testclass:
package com.webservice.spring;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
#RunWith(SpringRunner.class)
#SpringBootTest
public class ApiApplicationTests
{
#Test
public void contextLoads()
{
}
}
this is the definition in the model:
#NotNull
#Generated(value=GenerationTime.ALWAYS)
#Column(name = "lastchange", columnDefinition = "DATETIME", nullable = false)
private LocalDate lastchanged;
and a snippet of the StackTrace:

what can i do to prevent the test from failing?
You could do either of the following
Changing the default value for a column with an ALTER TABLE
statement, e.g.
ALTER TABLE users MODIFY created datetime NULL DEFAULT '1970-01-01'
Change the date column to allow NULL values, and update the existing
rows to change the zero dates to null values
The Answer:
in the Model Class:
#Column(name = "lastchange", columnDefinition = "DATETIME default '1900-01-01 00:00:00'", nullable = false)
private LocalDate lastchanged;
you can set the default in the Column Anotation
I'm trying to automatically generate a table in Hibernate and I keep getting errors, the table that it refers too has a primary key defined so idk what the problem is.
Here's the stack trace

Here is my entity
#Entity
#Table(name="foods")
public class Foods {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="food_id")
private Integer foodId;
#Column(name="food_name")
private String foodName;
#Column(name="vendor_name")
private String vendorName;
#ManyToOne
#JoinColumn(name="foodCat_id")
private FoodCategory foodCategory;
}
any help is appreciated, thanks!
Hibernate will not recreate a column if it already exists. The foods table in the database probably has the food_id column but not defined as a primary key (and may not match the Hibernate definition from the Java class).
You can manually alter the table like so:
ALTER TABLE foods ADD PRIMARY KEY (food_id);
Or try dropping the table and re-run your code.
