All Implemented Interfaces:

Serializable

public class UrlBindingConflictException
extends StripesRuntimeException

This exception indicates that a URL does not contain enough information to map it to a single ActionBean class. In some cases, a URL may match more than one URL binding.

For example, suppose you have two ActionBeans with the URL bindings /foo/{param}/bar and /foo/{param}/blah. The paths /foo and /foo/X -- while legal, since any number of parameters or literals may be omitted from the end of a clean URL -- match both of the URL bindings. Since Stripes cannot determine from the URL the ActionBean to which to dispatch the request, it throws this exception to indicate the conflict.

Since:

Stripes 1.5.1

Constructor Detail

UrlBindingConflictException

public UrlBindingConflictException(String message,
                           Class<? extends ActionBean> targetClass,
                           String path,
                           Collection<String> matches)

New exception indicating that the path does not map to a single ActionBean because it potentially matches all the URL bindings in the matches collection.

Parameters:

message - An informative message about what went wrong

targetClass - The class for which a URL could not be generated.

path - The offending path

matches - A collection of all the potentially matching URL bindings

UrlBindingConflictException

public UrlBindingConflictException(Class<? extends ActionBean> targetClass,
                           String path,
                           Collection<String> matches)

New exception indicating that the path does not map to a single ActionBean because it potentially matches all the URL bindings in the matches collection.

Parameters:

targetClass - The class for which a URL could not be generated.

path - The offending path

matches - A collection of all the potentially matching URL bindings

UrlBindingConflictException

public UrlBindingConflictException(String message,
                           String path,
                           Collection<String> matches)

New exception indicating that the path does not map to a single ActionBean because it potentially matches all the URL bindings in the matches collection.

Parameters:

message - An informative message about what went wrong

path - The offending path

matches - A collection of all the potentially matching URL bindings

UrlBindingConflictException

public UrlBindingConflictException(String path,
                           Collection<String> matches)

New exception indicating that the path does not map to a single ActionBean because it potentially matches all the URL bindings in the matches collection.

Parameters:

path - The offending path

matches - A collection of all the potentially matching URL bindings

Method Detail

getMessage

protected static String getMessage(Class<? extends ActionBean> targetClass,
                String path,
                Collection<String> matches)

Generate the message to pass to the superclass constructor

getPath

public String getPath()

Get the path that failed to map to a single ActionBean

getMatches

public Collection<String> getMatches()

Get all the URL bindings on existing ActionBeans that match the path

getTargetClass

public Class<? extends ActionBean> getTargetClass()

Get the ActionBean class for which a URL was being generated when this exception was thrown. If the exception occurred while dispatching a request, then this property will be null since the path cannot be associated with an ActionBean class. However, if it is thrown while generating a URL that is intended to point to an ActionBean, then this property will indicate the class that was being targeted.
