Method Detail

multipartResolver

@Bean
public org.springframework.web.multipart.support.StandardServletMultipartResolver multipartResolver()

To use multipart (based on Servlet 3.0) we need to mark the DispatcherServlet with a MultipartConfigElement in programmatic Servlet registration. Configuration settings such as maximum sizes or storage locations need to be applied at that Servlet registration level as Servlet 3.0 does not allow for those settings to be done from the MultipartResolver.

configureDefaultServletHandling

public void configureDefaultServletHandling(org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer configurer)

This allows for mapping the DispatcherServlet to "/" (thus overriding the mapping of the container’s default Servlet), while still allowing static resource requests to be handled by the container’s default Servlet. It configures a DefaultServletHttpRequestHandler with a URL mapping of "/**" and the lowest priority relative to other URL mappings.

Specified by:

configureDefaultServletHandling in interface org.springframework.web.servlet.config.annotation.WebMvcConfigurer

Overrides:

configureDefaultServletHandling in class org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

addInterceptors

public void addInterceptors(org.springframework.web.servlet.config.annotation.InterceptorRegistry registry)

In Internet Explorer http requests are cached by default. It's a problem when we want to provide a REST API. This interceptor adds headers in the responses to desactivate the cache. NB : static resources are cached but managed by the resource handlers

Specified by:

addInterceptors in interface org.springframework.web.servlet.config.annotation.WebMvcConfigurer

Overrides:

addInterceptors in class org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

Parameters:

registry -

addResourceHandlers

public void addResourceHandlers(org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry registry)

Add resources handler to help Spring to manage our static resources (from frontend and backend)

Specified by:

addResourceHandlers in interface org.springframework.web.servlet.config.annotation.WebMvcConfigurer

Overrides:

addResourceHandlers in class org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

addViewControllers

public void addViewControllers(org.springframework.web.servlet.config.annotation.ViewControllerRegistry registry)

Specified by:

addViewControllers in interface org.springframework.web.servlet.config.annotation.WebMvcConfigurer

Overrides:

addViewControllers in class org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

configureMessageConverters

public void configureMessageConverters(List<org.springframework.http.converter.HttpMessageConverter<?>> converters)

Spring MVC use a default objectMapper. Objects passed to and returned from the controllers are converted to and from HTTP messages by HttpMessageConverter instances. We must use our {objectMapper} because of the subtypes.... So we declare two message converters

• StringHttpMessageConverter to format the String sent by HTTP like a JSON object representation
• MappingJackson2HttpMessageConverter to use our {objectMapper}

To declare a JacksonHttpMessageConvet

Specified by:

configureMessageConverters in interface org.springframework.web.servlet.config.annotation.WebMvcConfigurer

Overrides:

configureMessageConverters in class org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter

supportedMediaTypes

public static List<org.springframework.http.MediaType> supportedMediaTypes()
