Spring 3 supports RESTful API/APP configuration examples

RESTful configuration example supporting APP & API Mode
XML example:
<Beans xmlns: context = http://www.springframework.org/schema/context
... Default-autowire = "byName">
<! -ByName, byType, autodetect -->
<Context: component-scan base-package = "com. **. controller"/>
<Bean class = "org. springframework. web. servlet. mvc. annotation. DefaultAnnotationHandlerMapping"/>
<Bean class = "org. springframework. web. servlet. mvc. annotation. AnnotationMethodHandlerAdapter"/>
 
<Bean class = "org. springframework. web. servlet. view. ContentNegotiatingViewResolver">
<Property name = "ignoreAcceptHeader" value = "true"/>
<Property name = "defaultContentType" value = "text/html"/>
<Property name = "mediaTypes">
<Map>
<Entry key = "json" value = "application/json"/>
<Entry key = "xml" value = "application/xml"/>
</Map>
</Property>
<Property name = "favorParameter" value = "false"/>
<Property name = "viewResolvers">
<List>
<Bean class = "org. springframework. web. servlet. view. BeanNameViewResolver"/>
<Bean class = "org. springframework. web. servlet. view. InternalResourceViewResolver">
<Property name = "viewClass" value = "org. springframework. web. servlet. view. JstlView"/>
<Property name = "prefix" value = "/WEB-INF/jsp/"/>
<Property name = "suffix" value = ". jsp"> </property>
</Bean>
</List>
</Property>

<Property name = "defaultViews">
<List>
<! -- For application/json -->
<Bean class = "org. springframework. web. servlet. view. json. MappingJacksonJsonView"/>
<! -- For application/xml -->
<Bean class = "org. springframework. web. servlet. view. xml. MarshallingView">
<Property name = "marshaller">
<Bean class = "org. springframework. oxm. xstream. xstreampolicaller"/>
<! -This is a very important column loader that can easily implement bean <=> xml, need to download additional (http://xstream.codehaus.org/download.html), it is easier to use than JAXB suite->
</Property>
</Bean>
</List>
</Property>
</Bean>
 
2. Exception of RESTful configuration in API Mode
Spring 3 Servlet + HttpMessageConverter + Annotation
-StringHttpMessageConverter: Text converter
-FormHttpMessageConverter: Form converter (application/x-www-form-urlencoded, ampped to MultiValueMap <String, String>)
-MarshallingHttpMessageConverter: XML converter (marshaller)
-MappingJacksonHttpMessageConverter: JSON converter (via Jackson's ObjectMapper
-AtomFeedHttpMessageConverter: ATOM converter (via ROME's Feed API)
-RssChannelHttpMessageConverter: RSS converter (via ROME's Feed API)
XML example:
<Bean class = "org. springframework. web. servlet. mvc. annotation. AnnotationMethodHandlerAdapter">
<Property name = "messageConverters">
<List>
<Ref bean = "jsonConverter"/>
<Ref bean = "marshallingConverter"/>
<Ref bean = "atomConverter"/>
</List>
</Property>
</Bean>
<Bean id = "jsonConverter" class = "org. springframework. http. converter. json. MappingJacksonHttpMessageConverter">
<Property name = "supportedMediaTypes" value = "application/json"/> <
/Bean>
 
<Bean id = "marshallingConverter" class = "org. springframework. http. converter. xml. MarshallingHttpMessageConverter">
<Constructor-arg ref = "jaxbMarshaller"/>
<Property name = "supportedMediaTypes" value = "application/xml"/>
</Bean>
<Bean id = "jaxbMarshaller" class = "org. springframework. oxm. jaxb. Jaxb2Marshaller">
<Property name = "classesToBeBound">
<List>
<Value> com. company. project. bean. EntityA </value>
<Value> com. company. project. bean. EntityB </value>
</List>
</Property>
</Bean>
<Bean id = "atomConverter" class = "org. springframework. http. converter. feed. AtomFeedHttpMessageConverter">
<Property name = "supportedMediaTypes" value = "application/atom + xml"/>
</Bean>
Controller code example:
@ RequestMapping (method = RequestMethod. GET, value = "/emp/{id}", headers = "Accept = application/json ")
Public @ ResponseBody EntityA getEntityA (@ PathVariable String id ){... Return EntityA ;}
 
2. Support for RESTful configuration exceptions in APP Mode
 
Spring 3 Servlet + MVC + Annotation
-ContentNegotiatingViewResolver: Resource representation negotiation
-BeanNameViewResolver: Common view resolver based on bean name as spring-like.
-UrlBasedViewResolver: Spring MVC view same as former Spring version (JSP for text/html)
-InternalResourceViewResolver: Mostly like to UrlBasedViewResolver.
-MappingJacksonJsonView: JSON view
-MarshallingView: XML view (via XStreamMarshaller or Jaxb2Marshaller, etc)
XML configuration example:
<Beans... Xmlns: p = http://www.springframework.org/schema/p xmlns: context = "http://www.springframework.org/schema/context "... Default-autowire = "byName"
<Context: component-scan base-package = "com. **. controller"/>
<Bean class = "org. springframework. web. servlet. mvc. annotation. DefaultAnnotationHandlerMapping"/>
<Bean class = "org. springframework. web. servlet. mvc. annotation. AnnotationMethodHandlerAdapter"/>
<Bean class = "org. springframework. web. servlet. view. ContentNegotiatingViewResolver">
<Property name = "ignoreAcceptHeader" value = "true"/>
<Property name = "defaultContentType" value = "text/html"/>
<Property name = "mediaTypes">
<Map>
<Entry key = "json" value = "application/json"/>
<Entry key = "html" value = "text/html"/>
<Entry key = "xml" value = "application/xml"/>
</Map>
</Property>
<Property name = "favorParameter" value = "false"/>
 
<Property name = "viewResolvers">
<List>
<Bean class = "org. springframework. web. servlet. view. BeanNameViewResolver"/>
<Bean class = "org. springframework. web. servlet. view. InternalResourceViewResolver">
<Property name = "viewClass" value = "org. springframework. web. servlet. view. JstlView"/>
<Property name = "prefix" value = "/WEB-INF/pages"/> <property name = "suffix" value = ". jsp"> </property>
</Bean>
</List>
</Property>
 
<Property name = "defaultViews">
<List>
<Bean class = "org. springframework. web. servlet. view. json. MappingJacksonJsonView"/>
<Bean class = "org. springframework. web. servlet. view. xml. MarshallingView">
<Property name = "marshaller">
<Bean class = "org. springframework. oxm. xstream. xstreampolicaller"/>
<! -It needs the jar libaray: xstream. jar (http://xstream.codehaus.org/download.html) -->
</Property>
</Bean>
</List>
</Property>
</Bean>
<Bean id = "messageSource" class = "org. springframework. context. support. ResourceBundleMessageSource" p: basename = "i18n/messages"/>
 
Controller code example:
@ PATH ("/{id }")
Public ModelAndView show (@ PathVariable java. lang. Integer id) throws Exception {
UserInfo userInfo = manger. get (id );
Return new ModelAndView ("/userinfo/edit", "userInfo", userInfo );
