整合SSH框架,出现 Servlet action is not available
web.xml的配置文件如下:
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
struts-config.xml的配置文件:
<struts-config>
<data-sources />
<form-beans >
<form-bean name="userForm" type="struts.form.UserForm" />
</form-beans>
<global-exceptions />
<global-forwards />
<action-mappings >
<action
attribute="userForm"
input="/JSP/user.jsp"
name="userForm"
path="/user"
scope="request"
type="struts.action.UserAction">
<forward name="success" path="/JSP/Success.jsp" />
<forward name="failure" path="/JSP/user.jsp" />
</action>
</action-mappings>
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
</plug-in>
<controller
processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />
<message-resources parameter="struts.ApplicationResources" />
</struts-config>
Spring中applicationContext.xml的配置如下:<beans>
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation">
<value>file:WebRoot/WEB-INF/hibernate.cfg.xml</value>
</property>
</bean>
<bean id="UseraDAO" class="HibernateSession.UseraDAO">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
<bean name="/user" class="struts.action.UserAction">
</bean>
<bean id="transactionManager"
class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory">
<ref local="sessionFactory" />
</property>
</bean>
<bean id="userDAOProxy"
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref local="transactionManager" />
</property>
<property name="target">
<ref local="UseraDAO" />
</property>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
</beans>
Hibernate的配置文件如下:
<hibernate-configuration>
<session-factory>
<property name="connection.username">ruanwxh</property>
<property name="connection.url">
jdbc:microsoft:sqlserver://localhost:1433
</property>
<property name="dialect">
org.hibernate.dialect.SQLServerDialect
</property>
<property name="myeclipse.connection.profile">SQL</property>
<property name="connection.password">ruan0953</property>
<property name="connection.driver_class">
com.microsoft.jdbc.sqlserver.SQLServerDriver
</property>
<mapping resource="HibernateSession/Usera.hbm.xml" />
</session-factory>
</hibernate-configuration>
映射文件:<hibernate-mapping>
<class name="HibernateSession.Usera" table="usera" schema="dbo" catalog="Test">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="increment" />
</id>
<property name="name" type="java.lang.String">
<column name="username" length="50" />
</property>
<property name="password" type="java.lang.String">
<column name="userpassword" length="50" />
</property>
<property name="age" type="java.lang.Integer">
<column name="age" />
</property>
</class>
</hibernate-mapping>
JSP的Action如下:
<html:form action="/user">
username : <html:text property="name"/><br/>
password : <html:password property="password"/><br/>
<html:submit value="提交"/><html:cancel value="取消"/>
</html:form>
[解决办法]
应该是路径问题
不能识别Action
[解决办法]
你既然用了Spring插件了，自然就是Spring去管理你的action
<action-mappings >
<action
attribute="userForm"
input="/JSP/user.jsp"
name="userForm"
path="/user"
scope="request"
type="struts.action.UserAction">
<forward name="success" path="/JSP/Success.jsp" />
<forward name="failure" path="/JSP/user.jsp" />
</action>
上面我标红的地方如果不用Spring。你可以直接写全名对应上，但你现在用到Spring了，struts.action.UserAction这个地方就应该是Spring中的一个bean id 了。你在applicationContext.xml中定义一个就行了（出错是因为你没定义）
[解决办法]
<action-mappings >
<action
attribute="userForm"
input="/JSP/user.jsp"
name="userForm"
path="/user"
scope="request"
>
<forward name="success" path="/JSP/Success.jsp" />
<forward name="failure" path="/JSP/user.jsp" />
</action>
[解决办法]
是struts-config.xml的配置文件错了:
<action-mappings >
<action
attribute="userForm"
input="/JSP/user.jsp"
name="userForm"
path="/user"
scope="request"
type="struts.action.UserAction">//这里错了
<forward name="success" path="/JSP/Success.jsp" />
<forward name="failure" path="/JSP/user.jsp" />
</action>
改成：
type="org.springframework.web.struts.DelegatingActionProxy"
[解决办法]
在web.xml里加入对spring的监听
