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：

<propertyname="registime"type="timestamp">
<columnname="registime"length="0"not-null="false"/>
</property>

<property name="registime" type="timestamp">
            <column name="registime" length="0" not-null="false" />
        </property>

时间輚不能为空的。
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。
二，

<hibernate-configuration>

<session-factory>
<propertyname="show_sql">true</property>
<propertyname="myeclipse.connection.profile">Myway</property>
<propertyname="connection.url">
jdbc:mysql://localhost:3306/myway
</property>
<propertyname="connection.username">root</property>
<propertyname="connection.password">1</property>
<propertyname="connection.driver_class">
com.mysql.jdbc.Driver
</property>
<propertyname="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<propertyname="current_session_context_class">thread</property>
<mappingresource="myway/po/User.hbm.xml"/>

</session-factory>

</hibernate-configuration>

<hibernate-configuration>

<session-factory>
	<property name="show_sql">true</property>
	<property name="myeclipse.connection.profile">Myway</property>
	<property name="connection.url">
		jdbc:mysql://localhost:3306/myway
	</property>
	<property name="connection.username">root</property>
	<property name="connection.password">1</property>
	<property name="connection.driver_class">
		com.mysql.jdbc.Driver
	</property>
	<property name="dialect">
		org.hibernate.dialect.MySQLDialect
	</property>
	<property name="current_session_context_class">thread</property>
	<mapping resource="myway/po/User.hbm.xml" />

</session-factory>

</hibernate-configuration>

以上是hibernate.cfg.xml的配置

<propertyname="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。

<hibernate-mapping>
<classname="myway.po.User"table="user"catalog="myway">
<idname="id"type="integer">
<columnname="id"/>
<generatorclass="assigned"></generator>
</id>
<propertyname="userid"type="string">
<columnname="userid"length="50"not-null="true"/>
</property>
<propertyname="userpwd"type="string">
<columnname="userpwd"length="50"/>
</property>
<propertyname="userques"type="string">
<columnname="userques"length="50"/>
</property>
<propertyname="userans"type="string">
<columnname="userans"length="50"/>
</property>
<propertyname="usermail"type="string">
<columnname="usermail"length="50"/>
</property>
<propertyname="integral"type="integer">
<columnname="integral"/>
</property>
<propertyname="grade"type="integer">
<columnname="grade"/>
</property>
<propertyname="sex"type="string">
<columnname="sex"length="8"/>
</property>
<propertyname="schoolname"type="string">
<columnname="schoolname"length="50"/>
</property>
<propertyname="birthday"type="string">
<columnname="birthday"length="50"/>
</property>
<propertyname="realname"type="string">
<columnname="realname"length="50"/>
</property>
<propertyname="nicheng"type="string">
<columnname="nicheng"length="50"/>
</property>
<propertyname="personalhobby"type="string">
<columnname="personalhobby"length="50"/>
</property>
<propertyname="otherinfo"type="string">
<columnname="otherinfo"length="200"/>
</property>
<propertyname="registime"type="timestamp">
<columnname="registime"length="0"not-null="false"/>
</property>
</class>
</hibernate-mapping>

<hibernate-mapping>
    <class name="myway.po.User" table="user" catalog="myway">
        <id name="id" type="integer">
            <column name="id" />
            <generator class="assigned"></generator>
        </id>
        <property name="userid" type="string">
            <column name="userid" length="50" not-null="true" />
        </property>
        <property name="userpwd" type="string">
            <column name="userpwd" length="50" />
        </property>
        <property name="userques" type="string">
            <column name="userques" length="50" />
        </property>
        <property name="userans" type="string">
            <column name="userans" length="50" />
        </property>
        <property name="usermail" type="string">
            <column name="usermail" length="50" />
        </property>
        <property name="integral" type="integer">
            <column name="integral" />
        </property>
        <property name="grade" type="integer">
            <column name="grade" />
        </property>
        <property name="sex" type="string">
            <column name="sex" length="8" />
        </property>
        <property name="schoolname" type="string">
            <column name="schoolname" length="50" />
        </property>
        <property name="birthday" type="string">
            <column name="birthday" length="50" />
        </property>
        <property name="realname" type="string">
            <column name="realname" length="50" />
        </property>
        <property name="nicheng" type="string">
            <column name="nicheng" length="50" />
        </property>
        <property name="personalhobby" type="string">
            <column name="personalhobby" length="50" />
        </property>
        <property name="otherinfo" type="string">
            <column name="otherinfo" length="200" />
        </property>
        <property name="registime" type="timestamp">
            <column name="registime" length="0" not-null="false" />
        </property>
    </class>
</hibernate-mapping>

以上是表的xml文件
（对数据库的操作通过po来实现）
下面是struts2部分。
一，

<struts>
<constantname="struts.custom.i18n.resources"value="globalMessages"/>

<constantname="struts.i18n.encodeing"value="UTF-8"/>

<packagename="Myway"extends="struts-default">
<actionname="zjreg"class="zjregisterAction">
<resultname="success"type="redirect">/jsp/zjregisterinfo.jsp</result>
<resultname="input">/jsp/zjregister.jsp</result>
</action>

<actionname="login"class="loginAction">
<resultname="success"type="redirect">/my_foot.jsp</result>
<resultname="input"type="redirect">/jsp/login.jsp</result>

</action>
</struts>

<struts>
<constant name="struts.custom.i18n.resources" value="globalMessages"/>

<constant name="struts.i18n.encodeing" value="UTF-8"/>

<package name="Myway" extends="struts-default">
	<action name="zjreg" class="zjregisterAction">
		<result name="success" type="redirect" >/jsp/zjregisterinfo.jsp</result>
		<result name="input">/jsp/zjregister.jsp</result>
	</action>
	
	<action name="login" class="loginAction">
		<result name="success" type="redirect">/my_foot.jsp</result>
		<result name="input"  type="redirect">/jsp/login.jsp</result>
	
	</action>
</struts>

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

privateUserServiceuserservice;


publicvoidsetUserservice(UserServiceuserservice){
this.userservice=userservice;
}

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

<validators>
<fieldname="username">
<field-validatortype="requiredstring">
<paramname="trim">true</param>
<message>usernameshouldbewrite</message>
</field-validator>
</field>

<fieldname="username">
<field-validatortype="regex">
<paramname="trim">ture</param>
<paramname="expression"><![CDATA[(\w{6,15})]]></param>
<message>usernamemustbetween6and15andalso</message>
</field-validator>
</field>

<fieldname="password">
<field-validatortype="requiredstring">
<paramname="trim">true</param>
<message>passwordshouldbewrite</message>
</field-validator>
</field>

<fieldname="password">
<field-validatortype="regex">
<paramname="trim">ture</param>
<paramname="expression"><![CDATA[(\w{6,15})]]></param>
<message>passwordmustbetween6and15andalso</message>
</field-validator>
</field>
</validators>

  <validators>
  	<field name="username">
  		<field-validator type="requiredstring">
  			<param name="trim">true</param>
  			<message>username should be write</message>
  		</field-validator>
  	</field>
  
  	<field name="username">
  		<field-validator type="regex">
  	 	    <param name="trim">ture</param>
  			<param name="expression"><![CDATA[(\w{6,15})]]></param>
  			<message>username must between 6 and 15 and also </message>
  		</field-validator>
  	</field>
  	
  		<field name="password">
  		<field-validator type="requiredstring">
  			<param name="trim">true</param>
  			<message>password should be write</message>
  		</field-validator>
  	</field>
  	
  	<field name="password">
  		<field-validator type="regex">
  	 	    <param name="trim">ture</param>
  			<param name="expression"><![CDATA[(\w{6,15})]]></param>
  			<message>password must between 6 and 15 and also </message>
  		</field-validator>
  	</field>
  </validators>

部分效验文件，虽然有这个文件，但strtus2还是会去访问action中的validate方法的。

spring部分
一，

<beanid="userservice"class="myway.userinterface.imp.UserServiceHbimp"></bean>
<beanid="loginAction"class="myway.action.LoginAction"scope="prototype">
<propertyname="userservice">
<reflocal="userservice"/>
</property>
</bean>
<beanid="zjregisterAction"class="myway.action.ZjregAction"scope="prototype">
<propertyname="userservice">
<reflocal="userservice"/>
</property>
</bean>
</beans>
