总结下Struts2的传参

方式一：

      直接在xxxAction中声明变量，并设置get、set方法。前台直接传过来 

1 public class UserAction { 2     /** 3      * Logger for this class 4      */ 5     private static final Logger logger = Logger.getLogger(UserAction.class); 6  7     UserService userService = null; 8  9     public UserService getUserService() {10         return userService;11     }12 13     public void setUserService(UserService userService) {14         this.userService = userService;15     }16 17     public String getName() {18         return name;19     }20 21     public void setName(String name) {22         this.name = name;23     }24 25     public int getPwd() {26         return pwd;27     }28 29     public void setPwd(int pwd) {30         this.pwd = pwd;31     }32 33     private String name = null;34     private int pwd = 0;35 36     public void login() {37         // boolean flag = userService.login(user);38         logger.info(name);39         logger.info(pwd);40         /*41          * if (flag == true) { } else { }42          */43     }44 45 }
xxxAction
 

      方式二：将数据封装到JavaBean中，在Action中声明get、set方法，接收该JavaBean。注意index.jsp中的表单提交方式：user.name，user.pwd 

1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" 2     pageEncoding="ISO-8859-1"%> 3  4  5  6 
 7 hello 8  9 10     
         11         name: 
12         pwd : 
13               
14     
15 16 
index.jsp
1 public class UserAction { 2     /** 3      * Logger for this class 4      */ 5     private static final Logger logger = Logger.getLogger(UserAction.class); 6  7     UserService userService = null; 8  9     public UserService getUserService() {10         return userService;11     }12 13     public void setUserService(UserService userService) {14         this.userService = userService;15     }16     private User user = null;17     18 19     public User getUser() {20         return user;21     }22 23     public void setUser(User user) {24         this.user = user;25     }26 27     public void login() {28         // boolean flag = userService.login(user);29         logger.info(user.getPwd());30         logger.info(user.getName());31         /*32          * if (flag == true) { } else { }33          */34     }35 36 }
xxxAction.java
1 public class User { 2     private Integer id; 3     private String name; 4     private Integer pwd; 5  6     public Integer getId() { 7         return id; 8     } 9 10     public void setId(Integer id) {11         this.id = id;12     }13 14     public String getName() {15         return name;16     }17 18     public void setName(String name) {19         this.name = name == null ? null : name.trim();20     }21 22     public Integer getPwd() {23         return pwd;24     }25 26     public void setPwd(Integer pwd) {27         this.pwd = pwd;28     }29 }
User.java
 
方式三：实现ModenDriven<T>接口实现传参
 UserAction.java 

1 public class UserAction extends ActionSupport implements ModelDriven
          { 2     /** 3      * Logger for this class 4      */ 5     private static final Logger logger = Logger.getLogger(UserAction.class); 6  7     UserService userService = null; 8  9     public UserService getUserService() {10         return userService;11     }12 13     public void setUserService(UserService userService) {14         this.userService = userService;15     }16 17     // have to initialize it18     private User user = new User();19 20     public User getUser() {21         return user;22     }23 24     public void setUser(User user) {25         this.user = user;26     }27 28     public String login() {29         logger.info(user.getPwd());30         logger.info(user.getName());31         return "success";32     }33 34     @Override35     public User getModel() {36         return user;37     }38 }
UserAction.java
User.java
1 public class User { 2  3     private Integer id; 4     private String name; 5     private Integer pwd; 6  7     public Integer getId() { 8         return id; 9     }10 11     public void setId(Integer id) {12         this.id = id;13     }14 15     public String getName() {16         return name;17     }18 19     public void setName(String name) {20         this.name = name == null ? null : name.trim();21     }22 23     public Integer getPwd() {24         return pwd;25     }26 27     public void setPwd(Integer pwd) {28         this.pwd = pwd;29     }30 31     public User() {32 33     }34 35 }
User.java
index.jsp 这里提交表单时候用的是name，pwd。
1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1" 2     pageEncoding="ISO-8859-1"%> 3  4  5  6 
 7 hello 8  9 10     
         11         name: 
 pwd : 
14     15 16 
index.jsp
