我无法连接到 heroku 数据库，当我将我的应用程序部署到 heroku 时，我在日志中得到了这个:
[localhost-startStop-1] WARN org.springframework.web.context.support.AnnotationConfigWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [path/DataBaseConfig.class]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
我的数据库配置:
public class DataBaseConfig {
@Resource
private Environment env;
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws URISyntaxException{
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
em.setPackagesToScan(env.getRequiredProperty("db.entity.package"));
em.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
em.setJpaProperties(getHibernateProperties());
return em;
}
@Bean
public BasicDataSource dataSource() throws URISyntaxException {
URI dbUri = new URI(System.getenv("jdbc:postgresql://user:password@Host:5432/databaseName"));
String username = dbUri.getUserInfo().split(":")[0];
String password = dbUri.getUserInfo().split(":")[1];
String dbUrl = "jdbc:postgresql://" + dbUri.getHost() + ':' + dbUri.getPort() + dbUri.getPath();
BasicDataSource basicDataSource = new BasicDataSource();
basicDataSource.setUrl(dbUrl);
basicDataSource.setUsername(username);
basicDataSource.setPassword(password);
return basicDataSource;
}
}
我做错了什么？
最佳答案
Heroku 使用 DATABASE_URL 环境变量来存储主数据库的位置。所以替换:
System.getenv("jdbc:postgresql://user:password@Host:5432/databaseName")
与:
System.getenv("DATABASE_URL")
