Method Detail

configure

public MainConfigurationProperties configure()

To configure options on Camel Main.

getRoutesCollector

public RoutesCollector getRoutesCollector()

setRoutesCollector

public void setRoutesCollector(RoutesCollector routesCollector)

To use a custom RoutesCollector.

getPropertyPlaceholderLocations

public String getPropertyPlaceholderLocations()

setPropertyPlaceholderLocations

public void setPropertyPlaceholderLocations(String location)

A list of locations to add for loading properties. You can use comma to separate multiple locations.

getDefaultPropertyPlaceholderLocation

public String getDefaultPropertyPlaceholderLocation()

setDefaultPropertyPlaceholderLocation

public void setDefaultPropertyPlaceholderLocation(String defaultPropertyPlaceholderLocation)

Set the default location for application properties if no locations have been set. If the value is set to "false" or empty, the default location is not taken into account.

Default value is "classpath:application.properties;optional=true".

isAutoConfigurationEnabled

@Deprecated
public boolean isAutoConfigurationEnabled()

Deprecated.

setAutoConfigurationEnabled

@Deprecated
public void setAutoConfigurationEnabled(boolean autoConfigurationEnabled)

Deprecated. use configure()

Whether auto-configuration of components/dataformats/languages is enabled or not. When enabled the configuration parameters are loaded from the properties component and configured as defaults (similar to spring-boot auto-configuration). You can prefix the parameters in the properties file with: - camel.component.name.option1=value1 - camel.component.name.option2=value2 - camel.dataformat.name.option1=value1 - camel.dataformat.name.option2=value2 - camel.language.name.option1=value1 - camel.language.name.option2=value2 Where name is the name of the component, dataformat or language such as seda,direct,jaxb.

The auto-configuration also works for any options on components that is a complex type (not standard Java type) and there has been an explicit single bean instance registered to the Camel registry via the Registry.bind(String, Object) method or by using the BindToRegistry annotation style.

This option is default enabled.
