Spring Boot gives an error of URL must start with 'jdbc' - postgresql

Question

I am trying to configure a Postgres database in spring boot using annotation configuration. I have all the database credentials in a file named database.properties and the configuration file is called DBconfig.java
database.url= jdbc:postgresql://localhost/mydb
database.driverClassName= com.postgresql.jdbc.Driver
database.username= postgres
database.password= password
The dbConfig file -
#Configuration
#PropertySource("classpath:databaseAccess/database.properties")
public class DBconfig {
#Value("${username}")
private String username;
#Value("${password}")
private String password;
#Value("${url}")
private String url;
#Bean
#Qualifier("postgresDB")
public DataSource dataSource() {
DataSourceBuilder dataSource = DataSourceBuilder.create();
dataSource.url(url);
dataSource.password(password);
//dataSource.driverClassName(driverClassName);
dataSource.username(username);
return dataSource.build();
}
#Bean
#Qualifier("jdbcTemplate")
public JdbcTemplate jdbcTemplate() {
return new JdbcTemplate(dataSource());
}
}
This is my main file
#SpringBootApplication
public class GetNotificationsApplication {
public static void main(String[] args) {
ApplicationContext ctx = new AnnotationConfigApplicationContext(DBconfig.class);
JdbcTemplate template= ctx.getBean("jdbcTemplate", JdbcTemplate.class);
template.execute("CREATE TABLE TEST( test VARCHAR(20))");
}
}
I keep getting the error
Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalArgumentException: URL must start with 'jdbc'

Answer 1

Try to change value for url parameter by defining port number for postgres. Assuming that postgres is running on 5432 which is the default port.
Change
jdbc:postgresql://localhost/mydb
To
jdbc:postgresql://localhost:5432/mydb
For port number check Find the host name and port using PSQL commands
UPDATE:
Also change #Value("${username}") to #Value("${database.username}") and other properties too by prefix database.
