Question

配置spring+struts1+ibtais时，向action中注入的service一直为null，怎么处理，求大神帮忙处理一下

我的spring配置文件
<bean id="userAction" class="com.shunde.action.UserAction" scope="singleton">
<property name="userService" ref="userSI"/>
</bean>

<bean id="userSI" class="com.shunde.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao" />
</bean>

<bean id="userService" parent="abstractTxDefinition">
<property name="target" ref="userSI" />
</bean>

<bean id="userDao" class="com.shunde.dao.impl.UserDaoImpl">
<property name="sqlMapClient" ref="sqlMapClient" />
</bean>

我的struts-config配置文件
<struts-config>

<form-beans>
<form-bean name="userManagerForm" type="com.shunde.form.UserForm" />
</form-beans>

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="classpath:applicationContext.xml" />
</plug-in>

<action-mappings>
<!-- 用户管理Action -->
<action path="/userAction" name="userManagerForm" scope="request"
type="com.shunde.action.UserAction">
</action>
</action-mappings>

<controller>
<set-property property="processorClass"
value="org.springframework.web.struts.DelegatingRequestProcessor" />
</controller>

<message-resources parameter="ApplicationResources" />

</struts-config>
我的action
public class UserAction extends BaseAction {
private UserService userService;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
try {
System.out.println(user.getUsername());
System.out.println(userService);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
System.out.println("aaaaaa");
this.userService = userService;
}
}

Answer 1

也是刚学，说的有不对的地方还请见谅呀\r\nstruts2就是通过前台页面(JSP)发出一个action的请求，在struts.xml中配置中寻找对应的action应该由哪个类来处理，它就会new 一个对应的action的实例，当然 在new action实例时要用到其它类，比如一个登录请求(loginAction)它要调用一个service(例如:loginService)，这里我们就可以\r\n回答到这，才发现，您说的不是 spring而是springside，不会，没听说过，

追问

我这个是struts1，不是struts2
