spring3.0支持restful实例

spring3.0以及restful，项目采用SPRING3.0+HIBERNATE2.5。数据库是oracle只有一个表。

view plaincopy to clipboardprint?
create table LMDZ??
(??
? KH_NUM VARCHAR2(20),??
? LM_NUM NUMBER(2)??
);?
create table LMDZ
(
? KH_NUM VARCHAR2(20),
? LM_NUM NUMBER(2)
);

首先在eclipse下新建web工程。web.xml文件配置如下：

好了，所有的源代码都贴出来了。整个服务端的程序可以跑在tomcat下做测试。接下来我们只需要提供rest客户端的接口让别的应用调用即可。下面再给出个调用的demo。这个项目比较简单。

还望大家多多指教，大家互相学习学习。
