Personalized Portal Service Model Of Agriculture Research And Implementation

With the rapid progressing of internet technology, internet has become one of the mostimportant ways to get information. In the aspect of agricultural informationization, ourcountry continues to strengthen the investment in agricultural information construction. Ithelps widen the resources of agricultural information. Portal services of traditional networkagricultural information lack unified standards and specifications. Problems, such asinformation repeat construction, classification chaos, low utilization and poor user experiencecould seriously restrict the integration and sharing of network agricultural information. Thispaper aims to put forward a novel mode and analysis the portal services. Furthermore, it alsoaims to establish a unified user authentication system by studying the single sign-ontechnology, which makes an implementary one-stop login in the agricultural informationservice platform. According to the project background requirements, agriculture informationportal services platform was constructed. My specific research contents are as follows:(1) Research on portal service mode. This paper puts forward the portal service mode byanalyzing the development trend of information portal service and studying on service modesin other fields. After analysis the construction of portal service mode, we studied anddemonstrated it from the aspects of definition and composition. We applied portal servicemodel in the field of agricultural informatization to design the agricultural information portalservice system.(2) The design and implementation of the single sign-on. We analyzed the CASprotocol single sign-on model and research on the CAS basic authentication, proxyauthentication processes of paper conversion and identity authentication. We also designedsingle sign-on process platform and established unified user authentication center by the CAStechnology. We studied a variety of system client authentication technology to realize the userin the system between the access to the back.(3) The design and implementation of agricultural information services portal platform.From the view of system design and software development, we established agriculturalinformation services Portal platform based on portal service mode, by analysis functionalrequirements of Portal platform, using Liferay Portal framework, integration of the Spring,Struts, and iBiats framework technologys. This Portal platform realized many service functions including personalized vertical portal customization, mail push, SMS push and soon. Finally, We verified the feasibility of portal service mode.
