添加功能的步骤：做页面——编写DAO类中的方法——编写和配置action。
如果多个action 使用一个formbean，这种事儿多发生在统一模块中，就可以用一个Action集中处理多个操作，而不要创建多个Action，是代码结构更加简洁。
可以使用 DispatchAction，需要引入struts-extras-1.3.10.jar
这个jar在struts 的blank 示例项目中没有可以在lib中找到，将其导入，有了该jar包才能以下的类 org.apache.struts.action.DispatchAction
于是后台action代码可以放在一个Action中如下：
1 package action; 2 3 import javax.servlet.http.HttpServletRequest; 4 import javax.servlet.http.HttpServletResponse; 5 6 import org.apache.struts.action.ActionForm; 7 import org.apache.struts.action.ActionForward; 8 import org.apache.struts.action.ActionMapping; 9 import org.apache.struts.actions.DispatchAction; 10 11 import dao.UserDAO; 12 import myuser.User; 13 14 public class UserAction extends DispatchAction { 15 16 /** 17 * 添加用户 18 * @param mapping 19 * @param form 20 * @param request 21 * @param response 22 * @return 23 * @throws Exception 24 */ 25 public ActionForward add(ActionMapping mapping, ActionForm form, HttpServletRequest request, 26 HttpServletResponse response) throws Exception { 27 User user = (User)form; 28 UserDAO dao = new UserDAO(); 29 dao.addUser(user); 30 return mapping.findForward("list");//跳转到userlist.jsp页面 31 } 32 33 /** 34 * 检查用户名是否存在 35 * @param mapping 36 * @param form 37 * @param request 38 * @param response 39 * @return 40 * @throws Exception 41 */ 42 public ActionForward checkExists(ActionMapping mapping, ActionForm form, HttpServletRequest request, 43 HttpServletResponse response) throws Exception { 44 User user = (User)form; 45 UserDAO dao = new UserDAO(); 46 String rel = dao.checkExists(user) ? "1" : "0"; 47 response.getWriter().write(rel); 48 return null; 49 } 50 51 /** 52 * 删除用户 53 * @param mapping 54 * @param form 55 * @param request 56 * @param response 57 * @return 58 * @throws Exception 59 */ 60 public ActionForward delete(ActionMapping mapping, ActionForm form, HttpServletRequest request, 61 HttpServletResponse response) throws Exception { 62 User user = (User)form; 63 UserDAO dao = new UserDAO(); 64 dao.deleteUser(user); 65 return null; 66 } 67 68 /** 69 * 获取用户信息 70 * @param mapping 71 * @param form 72 * @param request 73 * @param response 74 * @return 75 * @throws Exception 76 */ 77 public ActionForward getUserInfo(ActionMapping mapping, ActionForm form, HttpServletRequest request, 78 HttpServletResponse response) throws Exception { 79 User user = (User)form; 80 UserDAO dao = new UserDAO(); 81 user = dao.getUserInfo(user); 82 request.getSession().setAttribute("user",user); 83 return mapping.findForward("updateUser"); 84 } 85 86 /** 87 * 修改用户 88 * @param mapping 89 * @param form 90 * @param request 91 * @param response 92 * @return 93 * @throws Exception 94 */ 95 public ActionForward modify(ActionMapping mapping, ActionForm form, HttpServletRequest request, 96 HttpServletResponse response) throws Exception { 97 User user = (User)form; 98 UserDAO dao = new UserDAO(); 99 dao.updateUser(user); 100 return mapping.findForward("list"); 101 } 102 103 }
struts-config文件的配置：
1 <?xml version="1.0" encoding="UTF-8"?> 2 3 <!DOCTYPE struts-config PUBLIC 4 "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" 5 "http://struts.apache.org/dtds/struts-config_1_3.dtd"> 6 <struts-config> 7 <form-beans> 8 <form-bean name="user" type="myuser.User"/> 9 </form-beans> 10 11 <global-forwards> 12 <forward name="list" path="/userlist.jsp"/> 13 </global-forwards> 14 15 <action-mappings> 16 <action path="/user" type="action.UserAction" name="user" parameter="op"> 17 <forward name="updateUser" path="/updateUser.jsp" redirect="true"/> 18 </action> 19 <action path="/main" type="org.apache.struts.actions.DispatchAction" parameter="/WEB-INF/page/main.jsp" /> 20 </action-mappings> 21 </struts-config>
访问的话就是譬如：user.do?op=add，注意：parameter参数配置的就是操作op，op的值就是方法名。
通过DispatchAction，可以将多个使用同样formbean的action整合成一个action
org.apache.struts.action.ForwardAction 就是可以将jsp文件放置到 /WEB-INF下面，然后通过路径进行访问，配置如上，但是我访问main.do的时候出异常了，原因还没找到。
