简介： Maven整合SSH项目（六）

二.九 action层 UserAction

package com.yjl.web.action;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.yjl.pojo.User;
import com.yjl.service.UserService;

 @Description 类的相关描述
*/
@Controller
@Scope("prototype")
public class UserAction extends ActionSupport implements ModelDriven<User>{
  private static final long serialVersionUID = 1L;
  @Resource
  private UserService userService;
  private User user=new User();
  @Override
  public User getModel() {
    return user;
  }
  public String list(){
    List<User> userList=userService.findAllEntitys();
    ActionContext.getContext().getValueStack().set("userList", userList);
    return "list";
  }
  public String add(){
    System.out.println("输出值:"+user.toString());
    userService.addEntity(user);
    return "toList";
  }
  public String update(){
    userService.updateEntity(user);
    return "toList";
  }
  public String delete(){
    userService.deleteEntity(user.getId());
    return "toList";
  }
  public String getById(){
    User info=userService.getEntityById(user.getId());
    ActionContext.getContext().getValueStack().push(info);
    return "detail";
  }
}

返回值的 String 要与 struts-user.xml 的值相对应。
