android + Spring RESTful 简单登录

注:

url?format=json服务器端返回json数据

url?format=xml服务器端返回xml数据

url默认返回html数据

登录restful风格部分源码

android客户端导入springforandroid开源jar

spring-android-rest-template-1.0.0.RC1.jar

spring-android-core-1.0.0.RC1.jar

spring-android-auth-1.0.0.RC1.jar

服务器端部分代码(spring3.1.1+hibernate4.1.2(jpa2)完全注解方式实现)
