Join

protected Join(String pattern,
 boolean requestBinding)

Method Details

path

public static JoinPath path(String pattern)

Create a Rule specifying the inbound request Address to which this Join will apply. Any Parameter instances defined in the given pattern will be bound by default to the ServletRequest.getParameterMap() via the RequestParameterProvider SPI.

To disable RequestBinding parameter Binding, instead use pathNonBinding(String).

The given pattern may be parameterized:

/example/{param}
/example/{param1}/sub/{param2}
...

Parameters:

pattern - ParameterizedPattern matching the requested path.

See Also:

• ConfigurationRuleParameterBuilder.where(String)

pathNonBinding

public static JoinPath pathNonBinding(String pattern)

Create a Rule specifying the inbound request Address to which this Join will apply. Any Parameter instances defined in the given pattern will NOT be bound by default to the ServletRequest.getParameterMap().

To enable RequestBinding parameter Binding, instead use path(String).

The given pattern may be parameterized:

/example/{param}
/example/{param1}/sub/{param2}
...

Parameters:

pattern - ParameterizedPattern matching the requested path.

See Also:

• ConfigurationRuleParameterBuilder.where(String)

getCurrentJoin

public static Join getCurrentJoin(jakarta.servlet.http.HttpServletRequest request)

Retrieve the Join that was invoked on the current HttpServletRequest; if no Join was invoked, return null.

to

public Join to(String resource)

Description copied from interface: JoinPath

The internal server resource Address to be served when the specified path(String) is requested.

The given resource path may be parameterized:

/example/{param}.html
/css/{value}.css
...

Specified by:

to in interface JoinPath

withInboundCorrection

public Join withInboundCorrection()

Specifies that requests for the original internal resource path specified by to(String) will be redirected to the updated path specified by path(String).

withChaining

public Join withChaining()

Enable the target of this Join, specified by to(String), to be intercepted by the path(String) of another Join instance. If not activated, subsequent matching Join instances will not be evaluated on the current InboundRewrite instance.
