OA学习笔记-008-岗位管理Action层实现

一、分析

1,设计实体/表
设计实体 --> JavaBean --> hbm.xml --> 建表

2,分析有几个功能,对应几个请求。

3,实现功能:
1,写Action类,写Action中的方法,确定Service中的方法。
2,写Service方法,确定Dao中的方法。
3,写Dao方法。
4,写JSP

============================

请求数量 地址栏
转发 1 不变
重定向 2 变化

 

增删改查共4个功能,需要6个请求。
所以需要相应的6个Action方法,每个Action方法处理一种请求。


作用 方法名 返回值 对应的页面
----------------------------------------------------
列表 list() list list.jsp
删除 delete() toList
添加页面 addUI() addUI addUI.jsp
添加 add() toList
修改页面 editUI() editUI editUI.jsp
修改 edit() toList

<result name="toList" type="redirectAction">role_list</result>

 

role_* ---> {1}

role_list list
role_addUI addUI
role_delete delete

二、代码

1.Action层

  1 package cn.itcast.oa.view.action;
  2 
  3 import java.util.List;
  4 
  5 import javax.annotation.Resource;
  6 
  7 import org.springframework.context.annotation.Scope;
  8 import org.springframework.stereotype.Controller;
  9 
 10 import cn.itcast.oa.domain.Role;
 11 import cn.itcast.oa.service.RoleService;
 12 
 13 import com.opensymphony.xwork2.ActionContext;
 14 import com.opensymphony.xwork2.ActionSupport;
 15 import com.opensymphony.xwork2.ModelDriven;
 16 
 17 @Controller
 18 @Scope("prototype")
 19 public class RoleAction extends ActionSupport implements ModelDriven<Role> {
 20 
 21     private static final long serialVersionUID = 1L;
 22 
 23     @Resource
 24     private RoleService roleService;
 25 
 26     // private Long id;
 27     // private String name;
 28     // private String description;
 29 
 30     private Role model = new Role();
 31 
 32     public Role getModel() {
 33         return model;
 34     }
 35 
 36     /** 列表 */
 37     public String list() throws Exception {
 38         List<Role> roleList = roleService.findAll();
 39         ActionContext.getContext().put("roleList", roleList);
 40         return "list";
 41     }
 42 
 43     /** 删除 */
 44     public String delete() throws Exception {
 45         roleService.delete(model.getId());
 46         return "toList";
 47     }
 48 
 49     /** 添加页面 */
 50     public String addUI() throws Exception {
 51         return "saveUI";
 52     }
 53 
 54     /** 添加 */
 55     public String add() throws Exception {
 56         // // 封装到对象中
 57         // Role role = new Role();
 58         // role.setName(model.getName());
 59         // role.setDescription(model.getDescription());
 60         //
 61         // // 保存到数据库
 62         // roleService.save(role);
 63 
 64         roleService.save(model);
 65 
 66         return "toList";
 67     }
 68 
 69     /** 修改页面 */
 70     public String editUI() throws Exception {
 71         // 准备回显的数据
 72         Role role = roleService.getById(model.getId());
 73         ActionContext.getContext().getValueStack().push(role);
 74 
 75         return "saveUI";
 76     }
 77 
 78     /** 修改 */
 79     public String edit() throws Exception {
 80         // 1,从数据库中获取原对象
 81         Role role = roleService.getById(model.getId());
 82 
 83         // 2,设置要修改的属性
 84         role.setName(model.getName());
 85         role.setDescription(model.getDescription());
 86 
 87         // 3,更新到数据库
 88         roleService.update(role);
 89 
 90         return "toList";
 91     }
 92 
 93     // ---
 94 
 95     // public Long getId() {
 96     // return id;
 97     // }
 98     //
 99     // public void setId(Long id) {
100     // this.id = id;
101     // }
102     //
103     // public String getName() {
104     // return name;
105     // }
106     //
107     // public void setName(String name) {
108     // this.name = name;
109     // }
110     //
111     // public String getDescription() {
112     // return description;
113     // }
114     //
115     // public void setDescription(String description) {
116     // this.description = description;
117     // }
118 }

 

2.Service层

 1 package cn.itcast.oa.service.impl;
 2 
 3 import java.util.List;
 4 
 5 import javax.annotation.Resource;
 6 
 7 import org.springframework.stereotype.Service;
 8 import org.springframework.transaction.annotation.Transactional;
 9 
10 import cn.itcast.oa.dao.RoleDao;
11 import cn.itcast.oa.domain.Role;
12 import cn.itcast.oa.service.RoleService;
13 
14 @Service
15 @Transactional
16 public class RoleServiceImpl implements RoleService {
17 
18     @Resource
19     private RoleDao roleDao;
20 
21     public Role getById(Long id) {
22         return roleDao.getById(id);
23     }
24 
25     public void delete(Long id) {
26         roleDao.delete(id);
27     }
28 
29     public void save(Role role) {
30         roleDao.save(role);
31     }
32 
33     public void update(Role role) {
34         roleDao.update(role);
35     }
36 
37     public List<Role> findAll() {
38         return roleDao.findAll();
39     }
40 
41 }

 

3.Dao层

1 @Repository    //这里写了@Repository,则父类BaseDaoImpl的sessionFactory可以注入
2 public class RoleDaoImpl extends BaseDaoImpl<Role> implements RoleDao {
3 
4 }

 

4.View层
