方法详细信息

addMappingForServletNames

void addMappingForServletNames(EnumSet<DispatcherType> dispatcherTypes,
                               boolean isMatchAfter,
                               String... servletNames)

Adds a filter mapping with the given servlet names and dispatcher types for the Filter represented by this FilterRegistration.

Filter mappings are matched in the order in which they were added.

Depending on the value of the isMatchAfter parameter, the given filter mapping will be considered after or before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained.

If this method is called multiple times, each successive call adds to the effects of the former.

参数：

dispatcherTypes - the dispatcher types of the filter mapping, or null if the default DispatcherType.REQUEST is to be used

isMatchAfter - true if the given filter mapping should be matched after any declared filter mappings, and false if it is supposed to be matched before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained

servletNames - the servlet names of the filter mapping

抛出：

IllegalArgumentException - if servletNames is null or empty

IllegalStateException - if the ServletContext from which this FilterRegistration was obtained has already been initialized

getServletNameMappings

Collection<String> getServletNameMappings()

Gets the currently available servlet name mappings of the Filter represented by this FilterRegistration.

If permitted, any changes to the returned Collection must not affect this FilterRegistration.

返回：

a (possibly empty) Collection of the currently available servlet name mappings of the Filter represented by this FilterRegistration

addMappingForUrlPatterns

void addMappingForUrlPatterns(EnumSet<DispatcherType> dispatcherTypes,
                              boolean isMatchAfter,
                              String... urlPatterns)

Adds a filter mapping with the given url patterns and dispatcher types for the Filter represented by this FilterRegistration.

Filter mappings are matched in the order in which they were added.

Depending on the value of the isMatchAfter parameter, the given filter mapping will be considered after or before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained.

If this method is called multiple times, each successive call adds to the effects of the former.

参数：

dispatcherTypes - the dispatcher types of the filter mapping, or null if the default DispatcherType.REQUEST is to be used

isMatchAfter - true if the given filter mapping should be matched after any declared filter mappings, and false if it is supposed to be matched before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained

urlPatterns - the url patterns of the filter mapping

抛出：

IllegalArgumentException - if urlPatterns is null or empty

IllegalStateException - if the ServletContext from which this FilterRegistration was obtained has already been initialized

getUrlPatternMappings

Collection<String> getUrlPatternMappings()

Gets the currently available URL pattern mappings of the Filter represented by this FilterRegistration.

If permitted, any changes to the returned Collection must not affect this FilterRegistration.

返回：

a (possibly empty) Collection of the currently available URL pattern mappings of the Filter represented by this FilterRegistration
