Re: [] Online Training Courses


I'm using spring boot 3.0.2, and jakarta package almost everywhere, but i get this warning :

2023-02-02T02:19:19.452+01:00  WARN 33455 --- [           main] org.hibernate.orm.deprecation            : HHH90000021: Encountered deprecated setting [javax.persistence.sharedCache.mode], use [jakarta.persistence.sharedCache.mode] instead

When i checked my classes i found this class that populate DB for testing :

package io.cloudgalaxy.galaxyback.config;
import java.sql.SQLException;

import javax.sql.DataSource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Configuration;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.init.ScriptUtils;

import jakarta.annotation.PostConstruct;


public class DatabaseConfig {

private JdbcTemplate jdbcTemplate;
private Resource dataScript;

public void initialize() {
try {
DataSource dS = jdbcTemplate.getDataSource();
if(dS != null)
ScriptUtils.executeSqlScript(dS.getConnection(), dataScript);
throw new RuntimeException("Failed to execute database script");
} catch (SQLException e) {
throw new RuntimeException("Failed to execute database script", e);

As you can see it's using DataSource from javax, so i was looking for the equivalent in jakarta, only found DataSourceDefinition but the methode afterwards doesn't work (no getDataSource, no getConnections)>

Thank you in advance

Yes there's this Java EE course on udemy produced by myself and Tim Buchalka. Currently in production process for the Jakarta EE version.
