简单的SSH整合登录注册



1.这里用的是struts2+spring2+hibernate3.1。用到user表
2.请确定jar包不要重复。
3.用到了struts2的validation框架。spring的配置文件applicationContext.xml，如果启动fwq发现无法加载此配置，请放置到WEB-INF下。hibernate通过映射关联表格，和字段。如果出现不能为空的错误，请在user.hbm.xml中检查字段属性和配置属性有否冲突。比如：

从数据库开始说起。
一，设计方式接口——实现类（这里用的是老紫竹留言本的数据库部分代码）
接口实现如干方法，实现类实现接口中的所有方法。

[XML] view plain copy print ?

1. <property name="current_session_context_class">thread</property>  

<property name="current_session_context_class">thread</property>

这句必须有。不然会报错。如果不加上对应的是实现类中的错误。
三，表的映射关系
类似javabean的一个类文件，属性对应表中的字段，一个实例对应一条记录。

以上是struts.xml的部分配置（有于整合的spring本来action 后面的class是逻辑处理类的class文件，现在只是一个表示，这个表示用于spring识别这个action）
二，在action中通过提供一个上面的数据库操作接口的get方法，让spring调用的

5.         this.userservice = userservice;   
6.     }  

[Java] view plain copy print ?

1. private UserService userservice;  
2.       
3.       
4.     public void setUserservice(UserService userservice) {  
5.         this.userservice = userservice;  
6.     }  

private UserService userservice;
	
	
	public void setUserservice(UserService userservice) {
		this.userservice = userservice;
	}

类似这个样子。

action负责通过接口对象调用实现类完成登陆和注册功能，返回表示success，和input来转到不通的视图。

三，validation.xml更具不通的action类名字，来提供效验文件，这里提供的是LoginAction-validation.xml和ZjregisterAction-validation.xml
