簡要說明一些容易出問題的地方.
加載框架支持的順序是:
Spring,Hibernate,Struts.
先加載Spring支持.
注意在這里一定要把Hibernate3.2 Core 包加入.當然如果您需要
用注解來管理VO的話,也需要加入Hibernate 3.2 Annotations包.
Hibernate 3.2 Advanced可選.
注意在下一步的時候,把applicationContext.xml放在/WEB-INF下,當然
這不是必須的,不過放在這配置方便些.
第二步,加入Hibernate支持:
在加載hibernate支持時候注意Hibernate3.1的包在這里不選.(否則有沖突)
對于Spring Persistence 持久化的包可選.
最后加載Struts1.2支持,比較簡單,就不帖圖了.
只要注意了圖中的兩個問題,一般就不會出現莫名奇妙的
Servlet Action is not Assiable 的異常了.
給出部分配置文件源碼:
struts-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<action-mappings>
<action path="/login" parameter="method">
<forward name="ok" path="/ok.jsp" />
</action>
</action-mappings>
<message-resources parameter="com.web.struts.ApplicationResources" />
<!-- 控制器 -->
<controller
processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />
<!-- struts,spring集成插件 -->
<plug-in

</plug-in>
</struts-config>
Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

</web-app>
當然對于web.xml中的spring配置不是必須的(可選).
applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName"
value="com.mysql.jdbc.Driver">
</property>
<property name="url" value="jdbc:mysql://localhost/test"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>
</bean>
<bean name="/login" class="com.web.struts.action.LoginAction">
</bean>
</beans>
當然寫了一個LoginAction進行了測試,一切表現良好.
對于LoginAction和前臺頁就不貼出源碼了,比較簡單.
