struts1.x的基本配置

1.先配置web.xml


  <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>
    <load-on-startup>0</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>


2.配置struts-config.xml


//这个是声明ActionForm
<form-beans>
<form-bean name="userform" type="com.lubby.actionform.UserForm"></form-bean>
</form-beans>




//这个是写路径与action的mapping  path是请求的servlet去掉.do之后的名字.type是servlet路径 scope是有效范围  name是actionform的name
<action-mappings>
<action path="/login" type="com.lubby.action.LoginAction" scope="request"  name="userform">
<forward name="success" path="/success.jsp" ></forward>  
<forward name="error" path="/error.jsp" ></forward>
</action>
</action-mappings>


3.写一个loginaction  servlet用于处理请求.必须继承Action类，execute是其执行的方法.




public class LoginAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {


UserForm user =  (UserForm)form;
request.setAttribute("user", user);
ActionForward af;
if("Tom".equals(user.getUsername)&&"123456".equals (user.getPassword)){
af  = mapping.findForward("success");
}

else{
af = mapping.findForward("error");
}


return af;
}


4.写一个actionform用于接收传递表单的数据
是一个javabean
