首先要在Action中声明所有要传向jsp页面的值的属性 然后生成get、set方法
UserAction.java
package cn.qdsoft.actions; import java.sql.Date; import java.util.List; import javax.annotation.Resource; import org.apache.struts2.convention.annotation.Action; import org.apache.struts2.convention.annotation.Namespace; import cn.qdsoft.BaseAction; import cn.qdsoft.dao.UserDAO; import cn.qdsoft.model.User; import cn.qdsoft.service.UserService; @Namespace("/user") public class UserAction extends BaseAction { // 必须声明为接口类型；important!!! @Resource private UserDAO userDAO; private List<User> userList; private User user; private Long id; private String login; private String name; private String passwd; private int type; private int status; private Date lastLogin; private Date gmtCreate; private Date gmtModified; private int createById; private int lastModifiedById; // 也在一个package中，package的名字不知道 // 父package 名字叫one @Action("list") public String list() { userList = userDAO.findAll(); return SUCCESS; } @Action("delete") public String delete() { System.out.println("user delete............"); Long id = getId(); System.out.println(id); return LIST; } public List<User> getUserList() { return userList; } public void setUserList(List<User> userList) { this.userList = userList; } public User getUser() { return user; } public void setUser(User user) { this.user = user; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getLogin() { return login; } public void setLogin(String login) { this.login = login; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPasswd() { return passwd; } public void setPasswd(String passwd) { this.passwd = passwd; } public int getType() { return type; } public void setType(int type) { this.type = type; } public int getStatus() { return status; } public void setStatus(int status) { this.status = status; } public Date getLastLogin() { return lastLogin; } public void setLastLogin(Date lastLogin) { this.lastLogin = lastLogin; } public Date getGmtCreate() { return gmtCreate; } public void setGmtCreate(Date gmtCreate) { this.gmtCreate = gmtCreate; } public Date getGmtModified() { return gmtModified; } public void setGmtModified(Date gmtModified) { this.gmtModified = gmtModified; } public int getCreateById() { return createById; } public void setCreateById(int createById) { this.createById = createById; } public int getLastModifiedById() { return lastModifiedById; } public void setLastModifiedById(int lastModifiedById) { this.lastModifiedById = lastModifiedById; } }如果在User.java中已有了一下代码
private Long id; private String login; private String name; private String passwd; private int type; private int status; private Date lastLogin; private Date gmtCreate; private Date gmtModified; private int createById; private int lastModifiedById;以及get、set方法就不需要在action中写了，只需要定义private User user；以及user的get、set
list.jsp

统一name和value
struts2 <s:textfield> 标签与<s:property>标签value值设置为action属性值或者对象的属性值 2.<s:textfield> 标签不能直接引用必须通过ognl表达式获取 <s:textfield id="login" name="user.login" cssClass="form-control" value="%{account}" /> <s:textfieldname="personAge" label="年龄" value="%{person.personAge}"/>
