I am trying run a spring-boot application which uses hibernate via spring-jpa, but i am getting this error:

my hibernate configuration is that (the dialect configuration is in the last method from this class):
@Configuration

public class HibernateConfig {

sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}

dataSource.setDriverClassName("org.postgresql.Driver");
dataSource.setUrl("jdbc:postgresql://localhost:5432/teste?charSet=LATIN1");
dataSource.setUsername("klebermo");
dataSource.setPassword("123");
return dataSource;
}
@Bean
@Autowired

txManager.setSessionFactory(sessionFactory);

}
};
}
}
what I am doing wrong here?
This question is related to
java
hibernate
maven
jpa
spring-boot
I reproduced this error message in the following three cases:
The obvious solution is to create new database user with the same username and password as in the spring-boot app or change username and password in your spring-boot app files to match an existing database user and grant sufficient privileges to that database user. In case of MySQL database this can be done as shown below:
mysql -u root -p
>CREATE USER 'theuser'@'localhost' IDENTIFIED BY 'thepassword';
>GRANT ALL ON *.* to theuser@localhost IDENTIFIED BY 'thepassword';
>FLUSH PRIVILEGES;
Obviously there are similar commands in Postgresql but I haven't tested if in case of Postgresql this error message can be reproduced in these three cases.
My problem was that embedded database was already connected. close connection
I ran into the same problem and my issue was that the DB I was trying to connect to didn't exist.
I created the DB, verified the URL/connection string and reran and everything worked as expected.
I also had this problem. In my case it was because of no grants were assigned to MySQL user. Assigning grants to MySQL user which my app uses resolved the issue:
grant select, insert, delete, update on my_db.* to 'my_user'@'%';
I also faced a similar issue. But, it was due to the invalid password provided. Also, I would like to say your code seems to be old-style code using spring. You already mentioned that you are using spring boot, which means most of the things will be auto configured for you. hibernate dialect will be auto selected based on the DB driver available on the classpath along with valid credentials which can be used to test the connection properly. If there is any issue with the connection you will again face the same error. only 3 properties needed in application.properties
# Replace with your connection string
spring.datasource.url=jdbc:mysql://localhost:3306/pdb1
# Replace with your credentials
spring.datasource.username=root
spring.datasource.password=
I was facing a similar problem when starting up the application (using Spring Boot) with the database server down.
Hibernate can determine the correct dialect to use automatically, but in order to do this, it needs a live connection to the database.
add spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLDialect
in application.properties file
I got this error when my database was not created. After creating the DB manually, it worked fine.
If you're using Spring Boot, you don't need to provide the JPA and Hibernate configuration explicitly, as Spring Boot can do that for you.
In the application.properties
Spring Boot configuration file, you have the add your database configuration properties:
spring.datasource.driverClassName = "org.postgresql.Driver
spring.datasource.url = jdbc:postgresql://localhost:5432/teste?charSet=LATIN1
spring.datasource.username = klebermo
spring.datasource.password = 123
And, in the same application.properties
configuration file, you can also set custom Hibernate properties:
# Log SQL statements
spring.jpa.show-sql = false
# Hibernate ddl auto for generating the database schema
spring.jpa.hibernate.ddl-auto = create
# Hibernate database Dialect
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
That's it!
I had the same issue and after debugging it turns out that Spring application.properties had wrong IP address for DB server
spring.datasource.url=jdbc:oracle:thin:@WRONG:1521/DEV
Adding spring.jpa.database-platform=org.hibernate.dialect.MariaDB53Dialect
to my properties file worked for me.
PS: i'm using MariaDB
In spring boot for jpa java config you need to extend JpaBaseConfiguration and implement it's abstract methods.
@Configuration
public class JpaConfig extends JpaBaseConfiguration {
@Override
protected AbstractJpaVendorAdapter createJpaVendorAdapter() {
final HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
return vendorAdapter;
}
@Override
protected Map<String, Object> getVendorProperties() {
Map<String, Object> properties = new HashMap<>();
properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
}
}
In my case, the root cause of this exception comes from using an old version mysql-connector and I had this error :
unable to load authentication plugin 'caching_sha2_password'. mysql
Adding this line to the mysql server configuration file (my.cnf or my.ini) fix this issue :
default_authentication_plugin=mysql_native_password
I had the same error after using the hibernate code generation
https://www.mkyong.com/hibernate/how-to-generate-code-with-hibernate-tools/
then the hibernate.cfg.xml
was created in /src/main/java
but without the connection parameters
after removing it - my problem was solved
Make sure your application.properties
has all correct info: (I changed my db port from 8889
to 3306
it worked)
db.url: jdbc:mysql://localhost:3306/test
This happened to me because I hadn't added the conf.configure();
before beginning the session:
Configuration conf = new Configuration();
conf.configure();
I got this issue when Eclipse was unable to find the JDBC driver. Had to do a gradle refresh from the eclipse to get this work.
I faced the same issue: The db I was trying to connect did not exist. I used jpa.database=default
(which I guess means it will try to connect to the database and then auto select the dialect). Once I started the database, it worked fine without any change.
It turns out there is no one mentioning set spring.jpa.database=mysql
in application.properties
file, if you use Spring JPA. This is the simplest answer to me and I want to share in this question.
Make sure that you have enter valid detail in application.properties and whether your database server is available. As a example when you are connecting with MySQL check whether XAMPP is running properly.
Make sure you have your database in your pom like OP did. That was my problem.
I faced this issue due to Mysql 8.0.11 version reverting back to 5.7 solved for me
I had same issue. adding this to the application.properties solved the issue:
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect
this is happening because your code is not bale to connect the database. Make sure you have mysql driver and username, password correct.
For those working with AWS MySQL RDS, it may occur when you are unable to connect to the database. Go to AWS Security Groups setting for MySQL RDS and edit the inbound IP rule by refreshing MyIP.
I faced this issue and doing above got the problem fixed for me.
If the preceding error in log was this: "ERROR - HikariPool-1 - jdbcUrl is required with driverClassName" then the solution is to rewrite "url" to "jdbc-url" according to this: Database application.yml for Spring boot from applications.properties
The following are some of the reasons for the hibernate.dialect
not set issue.
Most of these exceptions are shown in the startup log which is finally followed by the mentioned issue.
Example: In Spring boot app with Postgres DB
org.postgresql.util.PSQLException: FATAL: database "foo" does not exist
In application.properties
file,
spring.datasource.url = jdbc:postgresql://localhost:5432/foo
but foo
didn't exist.
So I created the database from pgAdmin for postgres
CREATE DATABASE foo;
org.postgresql.util.PSQLException: FATAL: password authentication failed for user "postgres"
spring.datasource.username= {DB USERNAME HERE}
spring.datasource.password= {DB PASSWORD HERE}
In my case the user could not connect to the database. If will have same issue if the log contains a warning just before the exception:
WARN HHH000342: Could not obtain connection to query metadata : Login failed for user 'my_user'.
If you are using this line:
sessionFactory.getHibernateProperties().put("hibernate.dialect", env.getProperty("hibernate.dialect"));
make sure that env.getProperty("hibernate.dialect")
is not null.
I had the same issue and it was caused by being unable to connect to the database instance. Look for hibernate error HHH000342 in the log above that error, it should give you an idea to where the db connection is failing (incorrect username/pass, url, etc.)
I had the same Error,
Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
in my case the WAR had application.properties inside that pointed to development server
where external application.properties was pointing to the right DB server.
make sure you don't have any other application.properties in the classpath / jars...
Same but in a JBoss WildFly AS.
Solved with properties in my META-INF/persistence.xml
<properties>
<property name="hibernate.transaction.jta.platform"
value="org.hibernate.service.jta.platform.internal.JBossAppServerJtaPlatform" />
<property name="spring.jpa.database-platform" value="org.hibernate.dialect.PostgreSQLDialect" />
<property name="spring.jpa.show-sql" value="false" />
</properties>
