接口 WebMvcConfigurer

方法详细资料

• configurePathMatch

  default void configurePathMatch​(PathMatchConfigurer configurer)

  Helps with configuring HandlerMappings path matching options such as trailing slash match, suffix registration, path matcher and path helper. Configured path matcher and path helper instances are shared for:

  • RequestMappings
  • ViewControllerMappings
  • ResourcesMappings

  从以下版本开始:

  4.0.3

• configureContentNegotiation

  default void configureContentNegotiation​(ContentNegotiationConfigurer configurer)

  Configure content negotiation options.

• configureAsyncSupport

  default void configureAsyncSupport​(AsyncSupportConfigurer configurer)

  Configure asynchronous request handling options.

• configureDefaultServletHandling

  default void configureDefaultServletHandling​(DefaultServletHandlerConfigurer configurer)

  Configure a handler to delegate unhandled requests by forwarding to the Servlet container's "default" servlet. A common use case for this is when the DispatcherServlet is mapped to "/" thus overriding the Servlet container's default handling of static resources.

• addFormatters

  default void addFormatters​(FormatterRegistry registry)

  Add Converters and Formatters in addition to the ones registered by default.

• addInterceptors

  default void addInterceptors​(InterceptorRegistry registry)

  Add Spring MVC lifecycle interceptors for pre- and post-processing of controller method invocations and resource handler requests. Interceptors can be registered to apply to all requests or be limited to a subset of URL patterns.

• addResourceHandlers

  default void addResourceHandlers​(ResourceHandlerRegistry registry)

  Add handlers to serve static resources such as images, js, and, css files from specific locations under web application root, the classpath, and others.

• addCorsMappings

  default void addCorsMappings​(CorsRegistry registry)

  Configure cross origin requests processing.

  从以下版本开始:

  4.2

• addViewControllers

  default void addViewControllers​(ViewControllerRegistry registry)

  Configure simple automated controllers pre-configured with the response status code and/or a view to render the response body. This is useful in cases where there is no need for custom controller logic -- e.g. render a home page, perform simple site URL redirects, return a 404 status with HTML content, a 204 with no content, and more.

• configureViewResolvers

  default void configureViewResolvers​(ViewResolverRegistry registry)

  Configure view resolvers to translate String-based view names returned from controllers into concrete View implementations to perform rendering with.

  从以下版本开始:

  4.1

• addArgumentResolvers

  default void addArgumentResolvers​(List<HandlerMethodArgumentResolver> resolvers)

  Add resolvers to support custom controller method argument types.

  This does not override the built-in support for resolving handler method arguments. To customize the built-in support for argument resolution, configure RequestMappingHandlerAdapter directly.

  参数:

  resolvers - initially an empty list

• addReturnValueHandlers

  default void addReturnValueHandlers​(List<HandlerMethodReturnValueHandler> handlers)

  Add handlers to support custom controller method return value types.

  Using this option does not override the built-in support for handling return values. To customize the built-in support for handling return values, configure RequestMappingHandlerAdapter directly.

  参数:

  handlers - initially an empty list

• configureMessageConverters

  default void configureMessageConverters​(List<HttpMessageConverter<?>> converters)

  Configure the HttpMessageConverters to use for reading or writing to the body of the request or response. If no converters are added, a default list of converters is registered.

  Note that adding converters to the list, turns off default converter registration. To simply add a converter without impacting default registration, consider using the method extendMessageConverters(java.util.List) instead.

  参数:

  converters - initially an empty list of converters

• extendMessageConverters

  default void extendMessageConverters​(List<HttpMessageConverter<?>> converters)

  A hook for extending or modifying the list of converters after it has been configured. This may be useful for example to allow default converters to be registered and then insert a custom converter through this method.

  参数:

  converters - the list of configured converters to extend.

  从以下版本开始:

  4.1.3

• configureHandlerExceptionResolvers

  default void configureHandlerExceptionResolvers​(List<HandlerExceptionResolver> resolvers)

  Configure exception resolvers.

  The given list starts out empty. If it is left empty, the framework configures a default set of resolvers, see WebMvcConfigurationSupport.addDefaultHandlerExceptionResolvers(List, org.springframework.web.accept.ContentNegotiationManager). Or if any exception resolvers are added to the list, then the application effectively takes over and must provide, fully initialized, exception resolvers.

  Alternatively you can use extendHandlerExceptionResolvers(List) which allows you to extend or modify the list of exception resolvers configured by default.

  参数:

  resolvers - initially an empty list

  另请参阅:

  extendHandlerExceptionResolvers(List), WebMvcConfigurationSupport.addDefaultHandlerExceptionResolvers(List, org.springframework.web.accept.ContentNegotiationManager)

• extendHandlerExceptionResolvers

  default void extendHandlerExceptionResolvers​(List<HandlerExceptionResolver> resolvers)

  Extending or modify the list of exception resolvers configured by default. This can be useful for inserting a custom exception resolver without interfering with default ones.

  参数:

  resolvers - the list of configured resolvers to extend

  从以下版本开始:

  4.3

  另请参阅:

  WebMvcConfigurationSupport.addDefaultHandlerExceptionResolvers(List, org.springframework.web.accept.ContentNegotiationManager)

• getValidator

  @Nullable
  default Validator getValidator()

  Provide a custom Validator instead of the one created by default. The default implementation, assuming JSR-303 is on the classpath, is: OptionalValidatorFactoryBean. Leave the return value as null to keep the default.

• getMessageCodesResolver

  @Nullable
  default MessageCodesResolver getMessageCodesResolver()

  Provide a custom MessageCodesResolver for building message codes from data binding and validation error codes. Leave the return value as null to keep the default.
