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spring for android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 )
