Struts1入门案例

Struts1入门案例

1. 写一个注册页面，把请求交给 struts处理

<form action="${pageContext.request.contextPath }/Register.do" method="post">
   		用户名：<input type="text" name="username"><br/>
   		密码：<input type="password" name="password"><br/>
   		邮箱：<input type="text" name="email"><br/>
   		<input type="submit" value="注册">
 form>

2. 导入struts开发包，并在web.xml文件配置struts(ActionServlet)处理所有.do请求

  	ActionServlet
  	org.apache.struts.action.ActionServlet
  	 
      		config
      		/WEB-INF/struts-config.xml
    	 
    2
  	
  
  
  
  	ActionServlet
  	*.do
  

3. 在web-inf目录中加入struts的配置文件：struts-config.xml，并配置struts收到请求后找RegisterAction处理，并配置在找RegisterAction处理请求之前，把数据封装到formbean中

<struts-config>
	<form-beans>
		<form-bean name="UserFormBean" type="cn.csx.web.formbean.UserFormbean">form-bean>
	form-beans>

	

	<action-mappings>
		<action path="/Register" type="cn.csx.web.action.RegisterAction" name="UserFormBean">action>
	action-mappings>

struts-config>

4. 把封装数据formbean，以及处理请求的RegisterAction写出来

public class RegisterAction extends Action {

	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		
		UserFormbean bean = (UserFormbean) form;
		System.out.println(bean.getUsername());
		System.out.println(bean.getPassword());
		System.out.println(bean.getEmail());
		
		
		try{
			System.out.println("向数据注册用户！！");
			request.setAttribute("message", "注册成功");
			request.getRequestDispatcher("/message.jsp").forward(request, response);
		
		}catch (Exception e) {
			request.setAttribute("message", "注册失败");
			request.getRequestDispatcher("/message.jsp").forward(request, response);
		}
		
		return null;
	}

	
	
}
