我正在尝试将我的webapp部署到heroku。由于Heroku不允许使用Hibernate DB，因此我设置了一个postgres插件，并尝试配置我的应用程序以使用它。
然而，当我部署我的应用程序时，它成功构建，但是当我尝试打开应用程序时，我收到应用程序错误。似乎tomcat服务器无法连接到postgres数据库，并且由于某种原因，它看起来像是尝试连接到localhost。 Heroku logs位于此帖的底部。
DataConfig.java
@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;
}
app.properties
newsitem.db.url=${JDBC_DATABASE_URL}
newsitem.db.driver=org.postgresql.Driver
newsitem.db.username=${JDBC_DATABASE_USERNAME}
newsitem.db.password=${JDBC_DATABASE_PASSWORD}
这似乎是失败的主要原因：
Caused by: org.h2.jdbc.JdbcSQLException: Connection is broken: "java.net.ConnectException: Connection refused (Connection refused): localhost" [90067-191]
