Spring3 with Servlets

1、spring3 with servletsspring3 with servletsactually, it is not servlets. it is simple servlet. it is org.springframework.web.httprequesthandler.the sample project is easyoauthprover. i will put some core codes and configuration here.spring configuration s:servlet-contt.xml bean id="requesttokens

2、ervlet" class="com.silly.easyoauthprovider.servlets.requesttokenhttprequesthandler" property name="oauthprovider" ref="oauthprovider" / property name="oauthvalidator" ref="oauthvalidator" / /bean the relat oauthprovider and oauthvalidator is con

3、figured in spring bean xml files.the web configuration file web.xml: context-param param-name contextconfiglocation /param-name param-value classpath:main-context.xml /param-value /context-param listener listener-class org.springframework.web.context.contextloaderlistener /listener-class /listener s

7、sthandler implements httprequesthandler private oauthprovider oauthprovider; private oauthvalidator oauthvalidator; public void oauthprovider(oauthprovider oauthprovider) this.oauthprovider = oauthprovider; public void setoauthvalidator(oauthvalidator oauthvalidator) this.oauthvalidator = oauthvalid

8、ator; public void handlerequest(httpservletrequest request, httpservletresponse response) throws servletexception, ioexception processrequest(request, response); public void processrequest(httpservletrequest request, httpservletresponse response) throws ioexception, servletexception try oauthmessage

9、 requestmessage = oauthservlet .getmessage(request, null); oauthconsumer consumer = oauthprovider.getconsumer(requestmessage); oauthaccessor accessor = new oauthaccessor(consumer); oauthvalidator.valimessage(requestmessage, accessor); / support the 'variable accessor secret' extension / desc

10、ribed in string secret = requestmessage .getparameter("oauth_accessor_secret"); if (secret != null) accessor.setproperty(oauthconsumer.accessor_secret, secret); / generate request_token and secret oauthprovider.generaterequesttoken(accessor); response.setcontenttype("text/plain"); outputstream out = response.getoutputstream(); oauth.foeode(oauth.newlist("oauth_token", accessor.requesttoken, "oauth_token_secret", accessor.tokensecret),
