title: Attempting to deploy Spring Boot app Using Postgres, Tomcat, Hibernate, and getting connection refused
body: <p>I am attempting to deploy my webapp to heroku. Since Heroku does not allow the use of a Hibernate DB, I have setup a postgres addon and attempted to configure my app to use it.</p>
  
  <p>However, when I deploy my app, it builds successfully, but when I try to open the app I get an application error. It appears that the tomcat server is unable to connect to the postgres database, and for some reason it looks like its trying to connect to localhost. The <code>Heroku logs</code> are at the bottom of this post.</p>
  
  <p><strong><code>DataConfig.java</code></strong></p>
  
  <pre><code>@Configuration
  public class DataConfig {
      @Autowired
      private Environment env;
  
      @Bean
      @Primary
      @ConfigurationProperties(prefix = "newsitem.db")
      public DataSource dataSource() {
          BasicDataSource ds = new BasicDataSource();
          ds.setDriverClassName(env.getProperty("newsitem.db.driver"));
          ds.setUrl(env.getProperty("newsitem.db.url"));
          ds.setUsername(env.getProperty("newsitem.db.username"));
          ds.setPassword(env.getProperty("newsitem.db.password"));
          return ds;
      }
  </code></pre>
  
  <p><strong><code>app.properties</code></strong></p>
  
  <pre><code>newsitem.db.url=${JDBC_DATABASE_URL}
  newsitem.db.driver=org.postgresql.Driver
  newsitem.db.username=${JDBC_DATABASE_USERNAME}
  newsitem.db.password=${JDBC_DATABASE_PASSWORD}
  </code></pre>
  
  <p>This appears to be the primary cause of failure:</p>
  
  <p><code>Caused by: org.h2.jdbc.JdbcSQLException: Connection is broken: "java.net.ConnectException: Connection refused (Connection refused): localhost" [90067-191]</code></p>
