我正在处理一个包含两个数据库连接的springboot应用程序。
一个是Mysql，另一个是Oracle..Mysql连接和数据源bean（MariaDB）没问题。.但是，当涉及到Oracle（这是Cloud Foundry中部署的外部数据库）时，会出现问题。 / p>
我的CloudConfig文件如下所示，
private DataSource createDataSource(final String serviceName, final Cloud cloud) {
final ExternalDependency externalDependency = cloud
.getServiceConnector(serviceName, ExternalDependency.class, null);
if (externalDependency == null) {
throw new InvalidConfigurationException(
String.format("Error getting ServiceConnector for External Dependency with serviceName=[%s]", serviceName)
);
}
HikariDataSource dataSource = null;
try {
final HikariConfig config = new HikariConfig();
config.setDriverClassName(requiredStringProperty("driverClassName", externalDependency, serviceName));
config.setJdbcUrl(requiredStringProperty("jdbcUrl", externalDependency, serviceName));
config.setUsername(requiredStringProperty("username", externalDependency, serviceName));
config.setPassword(requiredStringProperty("password", externalDependency, serviceName));
config.setConnectionTestQuery(requiredStringProperty("connectionTestQuery", externalDependency, serviceName));
config.setMinimumIdle(intProperty("minimumIdle", externalDependency, serviceName, 1));
config.setMaximumPoolSize(intProperty("maximumPoolSize", externalDependency, serviceName, 5));
LOG.info("config values : {}, {}, {} ,{}, {}, {}, {}",
config.getDriverClassName(),
config.getJdbcUrl(),
config.getUsername(),
config.getPassword(),
config.getConnectionTestQuery(),
config.getMinimumIdle(),
config.getMaximumPoolSize());
LOG.info("Before HikariDatasource");
dataSource = new HikariDataSource(config);
LOG.info("After HikariDatasource");
/*OracleDataSource dataSource1 = new OracleDataSource();
dataSsetDriverClassName(requiredStringProperty("driverClassName", externalDependency, serviceName));
dataSource1.setJdbcUrl(requiredStringProperty("jdbcUrl", externalDependency, serviceName));
dataSource1.setUsername(requiredStringProperty("username", externalDependency, serviceName));
dataSource.
*/
String dataSourceDetails = dataSourceDetails(dataSource);
LOG.info("Available DataSource oracleDb: [{}]", dataSourceDetails);
} catch (Exception e) {
LOG.info("Info For The Error : {}", e.getMessage());
LOG.info("{}", e);
}
return dataSource;
我能够获得所有详细信息。.我已经检查了所有连接..它们的运行状况良好。
但是当我在Cloud Foundry中部署jar时，出现以下问题，请在下面找到堆栈跟踪，
Caused by: java.sql.SQLTransientConnectionException: HikariPool-0 - Connection is not available, request timed out after 30000ms.

有人可以帮忙吗？我从2天开始就遇到了这个问题！
