I am a beginner in Spring Boot and Hibernate, I did a project in the Spring Initializr with only the dependencies Web, DevTools e PostgreSQL
, but then I added the dependency spring-boot-starter-data-jpa
, I was following some tutorials and I made a configuration class, it follows the code:
package com.projetospringboot.meuprojeto.dao;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.jpa.JpaVendorAdapter;
import org.springframework.orm.jpa.vendor.Database;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import javax.sql.DataSource;
@Configuration
public class DataConfiguration {
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName("org.postgresql.Driver");
dataSource.setUrl(""+
"jdbc:postgresql://localhost:5432/BancoProjetoEventos");
dataSource.setUsername("postgres");
dataSource.setPassword("postgres");
return dataSource;
}
@Bean
public JpaVendorAdapter jpaVendorAdapter() {
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabase(Database.POSTGRESQL);
adapter.setShowSql(true);
adapter.setGenerateDdl(true);
adapter.setDatabasePlatform(""+
"org.hibernate.dialect.PostgreSQLDialect");
adapter.setPrepareConnection(true);
return adapter;
}
}
a and when I try to run the project it gives the following error:
Error starting ApplicationContext. To display the conditions report re-run
your application with 'debug' enabled.
2018-09-18 21:55:53.559 ERROR 2808 --- [ restartedMain]
o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no
embedded datasource could be configured.
Reason: Failed to determine a suitable driver class
Action:
Consider the following:
If you want an embedded database (H2, HSQL or Derby), please put it on
the classpath.
If you have database settings to be loaded from a particular profile you
may need to activate it (no profiles are currently active).
Process finished with exit code 0
By the way I understood it, I gave the url error that I put in, but I tested this url and it's right, it's connecting, does anyone know how to solve this error?
