Client

Create a bean to instantiate the CORBA client. The CORBA client uses connection pooling to improve performance.

@Bean("myclient")
@ConfigurationProperties("myclient")
public CorbaClient<MyInterface, MyException> client() {
    return CorbaClientBuilder.<MyInterface, MyException>create()
        .stub(c -> MyInterfaceHelper.narrow(c))
        .exception(e -> new RemotingException(e.myErrId, e.myErrText))
        .build();
}

The CORBA client is auto-configured from the application properties.

myclient.url=corbaloc::some.service:12345/some.name
myclient.request-timeout=30
myclient.inactivity-timeout=300

Wire in and use the CORBA client.

@Autowired
@Qualifier("myclient")
private CorbaClient<MyInterface, MyException> client;

public void foo(Person person) throws RemotingException {
    client.execute((c) -> c.addPerson(person));
}

The CORBA client may be configured using these application properties.

validate-on-borrow	false	Indicates if a connection must be validated when it is borrowed from the JDBC connection pool
validation-timeout	5 s	The amount of time to allow for a connection to be validated
request-timeout	60 s	The amount of time to allow for a request to the CORBA service to complete
backoff-period	1 s	The amount of time to back off when the circuit breaker trips
backoff-multiplier	1	The factor with which to increase the backoff period when the circuit breaker trips repeatedly
backoff-limit		The maximum amount of time to back off when the circuit breaker trips repeatedly
inactivity-timeout	300 s	The amount of time to allow before surplus connections to the CORBA service are pruned
maximum-lifetime	unlimited	The maximum lifetime of a connection to the CORBA service
