package com.teamtreehouse.contactmgr.config;

import org.apache.tomcat.dbcp.dbcp2.BasicDataSource;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;

import org.springframework.orm.hibernate5.LocalSessionFactoryBean;

import javax.sql.DataSource;
@Configuration
public class DataConfig {
@Autowired
  private Environment env;

  @Bean
  public LocalSessionFactoryBean sessionFactory() {
    Resource config = new ClassPathResource("hibernate.cfg.xml");
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setConfigLocation(config);
    sessionFactory.setPackagesToScan(env.getProperty("com.teamtreehouse.contactmgr.model"));
    sessionFactory.setDataSource(dataSource());
    return sessionFactory;
  }

  @Bean
  public DataSource dataSource() {
    BasicDataSource ds = new BasicDataSource();

Hi, I hope the answer is not too late.

Remember the challenges are like the code in the classes, however they're not exactly the same.

You're calling evironment variables that don't exist (In the challenge) and the hibernate configuration file (which is not present in the challenge neither). You could just simplify your code and it should be fine:

@Configuration
public class DataConfig {

  @Bean
  public LocalSessionFactoryBean sessionFactory() {
    LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
    sessionFactory.setPackagesToScan("com.teamtreehouse.contactmgr.model");
    sessionFactory.setDataSource(dataSource());
    return sessionFactory;
  }

  @Bean
  public DataSource dataSource(){
    BasicDataSource ds= new BasicDataSource();
    ds.setDriverClassName("org.h2.Driver");
    ds.setUrl("jdbc:h2:mem:contactmgr");
    return bds;
  }   
}

You had everything fine, you just had too much hahaha
