Spring3MVC+MyBatis+ExtJs3整合开发系列之三：人员管理模块

    hi,boys and girls,i come back again!

    承接上篇：Spring3MVC+MyBatis+ExtJs3整合开发系列之二：菜单模块，这次带来了Spring3MVC+MyBatis+ExtJs3整合开发系列之第三篇：人员管理模块。
   
    这次改动比较大，下面是模块结构图，总算把之前搭建的package都填满了：

persistence层

public interface UserMapper {
	Long getId();
	User login(Map<String,Object> param);
	User getUser(Map<String,Object> param);
	List<User> getUserList();
	void insertUser(User user);
	void insertUserRole(Map<String,Object> param);
	void updateUser(User user);
	void updateUserRole(Map<String,Object> param);
	void deleteUser(Map<String,Object> param);
	void deleteUserRole(Map<String,Object> param);
	void changeUserPassword(Map<String,Object> param);
}

    这里特别说明下xml配置中的"<cache />"缓存配置项，如果开启了缓存（这里就开启了），需要注意数据的刷新问题；我之前的菜单模块，就开启了缓存机制，导致角色变更后，菜单权限没相应变化，这就是缓存导致的。

service层

   好了，一个完整的人员管理模块就完成了，测试下模块功能吧。
   ……

   下篇：Spring3MVC+MyBatis+ExtJs3整合开发系列之四：角色管理模块

mark一下 晚上研究研究

持续关注...

最近看到extjs的风格都觉得腻歪。。可能用这个东西的人太多了。。不过支持lz，加油

不错不错，也想找时间做自己的东西！

extjs给了我们开发人员一个偷懒的借口，不需要专业的美工，也能做出用户体验一致的系统。
extjs的优势在于组件化，提供了一大堆强大的组件。

我现在做的项目用到了SPRIGMVC和MYbatis,但是没用EXTJS,我对那个新版本的MVC很是无语，换了个交叉编译的GWT，感觉还不错~

从代码职能划分角度看，extjs搞个mvc模式也未尝不可

想问问楼主有没试过整合后用到ORACLE的大字段有没出现过问题，我在整合后用到大字段，但是却报：Spring transaction synchronization needs to be active for setting values in iBATIS TypeHandlers that delegate to a Spring LobHandler
请问知道吗

楼主，我下载运行了，怎么登录不了？输入用户名和密码、验证码，点击确定后还是在登录界面，是哪里有问题？
