Method Details

renewalInterval

public EurekaUpdatingListenerBuilder renewalInterval(Duration renewalInterval)

Sets the interval between renewal. 30 seconds is used by default and it's not recommended to modify this value. Eureka protocol stores this value in seconds internally, and thus this method will convert the given interval into seconds, rounding up its sub-second part. See renew.

renewalIntervalSeconds

@Deprecated
public EurekaUpdatingListenerBuilder renewalIntervalSeconds(int renewalIntervalSeconds)

Deprecated.

Use renewalIntervalMillis(long).

Sets the interval between renewal in seconds. 30 is used by default and it's not recommended to modify this value. See renew.

renewalIntervalMillis

public EurekaUpdatingListenerBuilder renewalIntervalMillis(long renewalIntervalMillis)

Sets the interval between renewal in milliseconds. 30000 (30 seconds) is used by default and it's not recommended to modify this value. Eureka protocol stores this value in seconds internally, and thus this method will convert the given interval into seconds, rounding up its sub-second part. See renew.

leaseDuration

public EurekaUpdatingListenerBuilder leaseDuration(Duration leaseDuration)

Sets the lease duration. 90 seconds is used by default and it's not recommended to modify this value. Eureka protocol stores this value in seconds internally, and thus this method will convert the given duration into seconds, rounding up its sub-second part. See renew.

leaseDurationSeconds

@Deprecated
public EurekaUpdatingListenerBuilder leaseDurationSeconds(int leaseDurationSeconds)

Deprecated.

Use leaseDurationMillis(long).

Sets the lease duration in seconds. 90 is used by default and it's not recommended to modify this value. See renew.

leaseDurationMillis

public EurekaUpdatingListenerBuilder leaseDurationMillis(long leaseDurationMillis)

Sets the lease duration in milliseconds. 90000 (90 seconds) is used by default and it's not recommended to modify this value. Eureka protocol stores this value in seconds internally, and thus this method will convert the given duration into seconds, rounding up its sub-second part. See renew.

         return options.toBuilder()
                       .endpointRemapper(endpoint -> {
                           if (endpoint.host().equals("example.com")) {

                       })
                       .build();
     });

 // This request goes to 'node-1.example.com' or 'node-2.example.com'.
 derivedClient.call();
 

Note that the remapping does not occur recursively but only once.
