一、Action概要
二、动态调用
三、通配符(规则:*_*等价于{1_2})
四、获取参数
1 1、方式一:逐个获取（推荐使用） 2 package com.aaron.action.param; 3 import com.opensymphony.xwork2.ActionSupport; 4 public class ParamMethodOneAction extends ActionSupport{ 5 private int id; 6 private String userName; 7 private String userPass; 8 @Override 9 public String execute() throws Exception { 10 System.out.println("id:"+id+"---"+"userName:"+userName+"---"+"userPass:"+userPass); 11 this.addFieldError("id", id+""); 12 this.addFieldError("userName", userName); 13 this.addFieldError("userPass", userPass); 14 15 return SUCCESS; 16 } 17 public int getId() { 18 return id; 19 } 20 public void setId(int id) { 21 this.id = id; 22 } 23 public String getUserName() { 24 return userName; 25 } 26 public void setUserName(String userName) { 27 this.userName = userName; 28 } 29 public String getUserPass() { 30 return userPass; 31 } 32 public void setUserPass(String userPass) { 33 this.userPass = userPass; 34 } 35 } 36 37 2、方式二:用某个entity获取（推荐使用） 38 package com.aaron.action.param; 39 40 import com.aaron.action.model.User; 41 import com.opensymphony.xwork2.ActionSupport; 42 43 /** 44 * 传递参数一般使用这种方式 45 * @author qiuyong 46 */ 47 public class ParamMethodTwoAction extends ActionSupport { 48 49 private User user; 50 @Override 51 public String execute() throws Exception { 52 System.out.println("id:"+user.getId()+"---"+"userName:"+user.getUserName()+"---"+"userPass:"+user.getUserPass()); 53 this.addFieldError("id", user.getId()+""); 54 this.addFieldError("userName", user.getUserName()); 55 this.addFieldError("userPass", user.getUserPass()); 56 return SUCCESS; 57 } 58 59 public User getUser() { 60 return user; 61 } 62 63 public void setUser(User user) { 64 this.user = user; 65 } 66 67 } 68 69 3、方式三:利用inplModelDriven（不推荐使用） 70 package com.aaron.action.param; 71 import com.aaron.action.model.User; 72 import com.opensymphony.xwork2.ActionSupport; 73 import com.opensymphony.xwork2.ModelDriven; 74 75 /** 76 * @author qiuyong 77 * 这种方式一般不用 78 */ 79 public class ParamMethodThreeAction extends ActionSupport implements ModelDriven<User>{ 80 private User user=new User(); 81 82 @Override 83 public String execute() throws Exception { 84 System.out.println("id:"+user.getId()+"---"+"userName:"+user.getUserName()+"---"+"userPass:"+user.getUserPass()); 85 this.addFieldError("id", user.getId()+""); 86 this.addFieldError("userName", user.getUserName()); 87 this.addFieldError("userPass", user.getUserPass()); 88 return SUCCESS; 89 } 90 91 public User getModel() { 92 return user; 93 } 94 95 public User getUser() { 96 return user; 97 } 98 99 public void setUser(User user) {100 this.user = user;101 }102 }
五、访问Web元素
1、Map类型_Ioc方式（推荐使用这种方式） /** * (推荐使用这种方式)利用Ioc创造Map类型request、session、application * @author qiuyong */ public class WebElementMapIocAction extends ActionSupport implements RequestAware,SessionAware,ApplicationAware{ Map<String,Object> request; Map<String,Object> session; Map<String,Object> application; @Override public String execute() throws Exception { request.put("request", "MapIocRequest"); session.put("session","MapIocSession"); application.put("application","MapIocApplication"); return SUCCESS; } public void setRequest(Map<String, Object> request) { this.request=request; } public void setSession(Map<String, Object> session) { this.session=session; } public void setApplication(Map<String, Object> application) { this.application=application; } } 2、Map类型_Struts容器 /** * @author qiuyong * 利用Struts容器创造Map类型request、session、application */ public class WebElementMapActionContextAction extends ActionSupport { Map request; Map session; Map application; public WebElementMapActionContextAction() { request = (Map) ActionContext.getContext().get("request"); session = ActionContext.getContext().getSession(); application = ActionContext.getContext().getApplication(); } @Override public String execute() throws Exception { request.put("request", "MapActionContextRequest"); session.put("session","MapActionContextSession"); application.put("application","MapActionContextApplication"); return SUCCESS; } } 3、Servlet原始类型_Ioc方式 /** * @author qiuyong * 利用Ioc的方式创造原始类型的request、session、application */ public class WebElementRealIocAction extends ActionSupport implements ServletRequestAware { HttpServletRequest request; HttpSession session; ServletContext application; @Override public String execute() throws Exception { request.setAttribute("request","RealIocRequest"); session.setAttribute("session","RealIocSession"); application.setAttribute("application","RealIocApplication"); return SUCCESS; } public void setServletRequest(HttpServletRequest request) { this.request=request; this.session=request.getSession(); this.application=session.getServletContext(); } } 4、Servlet原始类型_Struts容器 /** * @author qiuyong * 利用Struts容器创造原始类型的request、session、application */ public class WebElementRealActionContextAction extends ActionSupport { HttpServletRequest request; HttpSession session; ServletContext application; public WebElementRealActionContextAction() { this.request=ServletActionContext.getRequest(); this.session=request.getSession(); this.application=session.getServletContext(); } @Override public String execute() throws Exception { request.setAttribute("request","RealActionContextRequest"); session.setAttribute("session","RealActionContextSession"); application.setAttribute("application","RealActionContextApplication"); return SUCCESS; } }
六、包含其他xml文件配置
