01 OA的概念
OA：办公自动化
在企业中，有些特别复杂的流程，这些流程有三个作用：
<1>对流程进行控制
<2>在走流程的过程中会产生一些数据，把这些数据整理出来，做查询、分析、统计。
* BI 智能分析 * 数据挖掘
产生这两个领域的原因
* 大量数据
<3>协同工作 完成一项工作需要好几个部门进行参与，这几个部门的数据之间是相互共享的，来完成一个任务。
02 书写每个模块的流程
1、需求分析
2、根据持久化类和映射文件建表
3、写dao和service
4、测试dao和service
5、写action
6、写配置文件
7、写页面
8、运行
03 表的设计
设计表的时候一定不能设计成饼状图或者网状图，而应该找到一个核心，形成星形关系表。
04 持久化类与映射文件

07 Jsp文件
<1>新建一个JSP文件，并且只保留<%@ page language= “java” import=“java.util." pageEncoding=“UTF-8” %>，将其他代码全部删除掉。然后将静态页面拷贝进来，这样就可以防止乱码问题。
<2>将css和js文件拷贝到webroot下。
<3>由于此时文件中会有很多的重复性代码，这时候可以新建一个common.jsp，将所有的重复代码放在这个jsp，然后使其他的jsp页面通过<%@ include file= “/WEB-INF/jsp/common/common.jsp” %>将common.jsp包含进本jsp中，提高代码的复用性。
<4>将jsp文件中所有的相对路径替换成相对于本应用的路径，也就是将类似“…/”替换成“${pageContext.request.contextPath}”。
<5>修改显示数据的静态文本为动态的（<s:property value="”/>）。

1、泛型的扩展知识
<1>泛型是Java中的一种类型。
<2>泛型是ParameterizedType
* 泛型的组成
Class（类或接口）<T,E,F>
Class 类或者接口
T,E,F 类或者接口的参数
<3>参数的传递方式
* 在创建对象的时候把参数传递进去。
* public interface A
public class B implements A
public class D extends B
<4>得到泛型的方式
clazz.getGenericSuperclass();
注：如果clazz的类型不是泛型，那么返回将是其父类的class。

cn.itheima.oa.dao.impl.PostDaoImpl.java
public class PostDaoImpl extends BaseDaoImpl {
}
spring/application-post.xml
<?xml version ="1.0" encoding="UTF-8" ?> <bean id ="postDao" class="cn.itheima.oa.dao.impl.PostDaoImpl" >
<property name ="sessionFactory" >
<ref bean ="sessionFactory" />
</property>
</bean>
/spring/applicationContext.xml
<?xml version ="1.0" encoding="UTF-8" ?> <import resource ="applicationContext-db.xml" />
<import resource ="applicationContext-department.xml" />
<import resource ="applicationContext-post.xml" />
cn.itheima.oa.test.PostTest.java
public class PostTest extends BaseSpring {
@Test
public void test(){
PostDaoImpl postDao = (PostDaoImpl)context .getBean(“postDao”);
}
}
执行结果：
第二种配置方式：
spring/applicationContext-post.xml
<!-- 这里一定要设置abstract='true'，否则spring容器已启动就会创建baseDaoImpl对象，而这时候泛型没有确定类型，所以会报错 -->
<bean id ="baseDao" class="cn.itheima.oa.dao.impl.BaseDaoImpl" abstract="true" >
<property name ="sessionFactory" >
<ref bean ="sessionFactory" />
</property>
</bean>
<!-- 这里一定要写上parent，否则无法继承baseDao的property -->
<bean id ="postDao" class="cn.itheima.oa.dao.impl.PostDaoImpl" parent="baseDao" >
</bean>
13 利用BaseDao实现Post的Dao
cn.itheima.oa.dao.PostDao.java
public interface PostDao extends BaseDao{
}
cn.itheima.oa.dao.impl.PostDaoImpl.java
public class PostDaoImpl extends BaseDaoImpl< Post> implements PostDao {
}
cn.itheima.oa.service.PostService.java
public interface PostService {
public Collection getAllPosts() throws Exception;
public void savePost(Post post) throws Exception;
public void deletePost(Serializable pid) throws Exception;
public void updatePost(Post post) throws Exception;
public Post getPostById(Serializable pid) throws Exception;
}
cn.itheima.oa.service.impl.PostServiceImpl.java
public class PostServiceImpl implements PostService {
private PostDao postDao ;
public PostDao getPostDao() {
return postDao ;
}
public void setPostDao(PostDao postDao) {
this.postDao = postDao;
}
public void deletePost(Serializable pid) throws Exception {
this.postDao .deleteEntity(pid);
}
public Collection<Post> getAllPosts() throws Exception {
return postDao .getAllEntities();
}
public Post getPostById(Serializable pid)
throws Exception {
return (Post) postDao .getEntityById(pid);
}
public void savePost(Post post) throws Exception {
postDao.saveEntity(post);
}
public void updatePost(Post post) throws Exception {
postDao.updateEntity(post);
}
}
/spring/applicationContext-post.xml
<?xml version ="1.0" encoding="UTF-8" ?> <bean id ="baseDao" class="cn.itheima.oa.dao.impl.BaseDaoImpl" abstract="true" >
<property name ="sessionFactory" >
<ref bean ="sessionFactory" />
</property>
</bean>
<bean id ="postDao" class="cn.itheima.oa.dao.impl.PostDaoImpl" parent="baseDao" >
</bean>
<bean id ="postService" class="cn.itheima.oa.service.impl.PostServiceImpl" >
<property name ="postDao" >
<ref bean ="postDao" />
</property>
</bean>
cn.itheima.oa.test.PostTest.java
public class PostTest extends BaseSpring {
@Test
public void test(){
PostService postService = (PostService)context .getBean(“postService”);
System. out.println(postService);
}
}
执行结果：
注：之所以有了BaseDao之后还去写其他的Dao的原因是因为这些另建的Dao接口可以添加一些BaseDao没有的方法。
14 利用BaseDao实现Department的Dao
cn.itheima.oa.action.BaseAction.java
public class BaseAction extends ActionSupport implements ModelDriven {
private Class classt ;
private T t ;
public BaseAction() {
ParameterizedType clazz = (ParameterizedType)this .getClass().getGenericSuperclass();
classt = (Class)clazz.getActualTypeArguments()[0];
try {
t = (T) classt.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
}
public T getModel() {
return t ;
}
public static final String LISTACTION = "listAction";
public static final String ADD_UI = "addUI";
public static final String UPDATE_UI = "updateUI";
public static final String ACTION2ACTION = "action2action";
public static String listAction = LISTACTION;
public static String add_ui = ADD_UI;
public static String update_ui = UPDATE_UI;
public static String action2action = ACTION2ACTION;
}
cn.itheima.oa.dao.DepartmentDao.java
public interface DepartmentDao extends BaseDao{
}
cn.itheima.oa.dao.impl.DepartmentDaoImpl.java
public class DepartmentDaoImpl extends BaseDaoImpl implements DepartmentDao {
}
cn.itheima.oa.service.impl.DepartmentServiceImpl.java
public class DepartmentServiceImpl implements DepartmentService {
private DepartmentDao departmentDao ;
public DepartmentDao getDepartmentDao() {
return departmentDao ;
}
public void setDepartmentDao(DepartmentDao departmentDao) {
this.departmentDao = departmentDao;
}
public void deleteDepartment(Serializable departmentId) throws Exception {
departmentDao.deleteEntity(departmentId);
}
public Collection<Department> getAllDepartments() throws Exception {
return departmentDao .getAllEntities();
}
public Department getDepartmentById(Serializable departmentId )
throws Exception {
return (Department) departmentDao.getEntityById(departmentId);
}
public void saveDepartment(Department department) throws Exception {
departmentDao.saveEntity(department);
}
public void updateDepartment(Department department) throws Exception {
departmentDao.updateEntity(department);
}
}
cn.itheima.oa.action.DepartmentAction.java
public class DepartmentAction extends BaseAction {
private DepartmentService departmentService ;
public DepartmentService getDepartmentService() {
return departmentService ;
}
public void setDepartmentService(DepartmentService departmentService) {
this.departmentService = departmentService;
}
public String showDepartments() throws Exception {
Collection<Department> departments = departmentService.getAllDepartments();
ActionContext. getContext().put("dList", departments);
return listAction ;
}
public String delete() throws Exception {
Department department2 = departmentService.getDepartmentById(this.getModel().getDid());
departmentService.deleteDepartment(department2.getDid());
return action2action ;
}
public String addUI() throws Exception {
return add_ui ;
}
public String add() throws Exception {
Department department = new Department();
BeanUtils. copyProperties(this.getModel(), department);
departmentService.saveDepartment(department);
return action2action ;
}
public String updateUI() throws Exception {
Department department = departmentService.getDepartmentById(this.getModel().getDid());
ActionContext. getContext().getValueStack().push(department);
return update_ui ;
}
public String update() throws Exception {
Department department = new Department();
BeanUtils. copyProperties(this.getModel(), department);
departmentService.updateDepartment(department);
return action2action ;
}
}
执行结果：
15 将已经实现的业务改为用注解的方式实现
cn.itheima.oa.dao.impl.BaseDaoImpl.java
public class BaseDaoImpl implements BaseDao {
//这里的属性虽然自己并不能注入，但是子类可以注入

16 通过注解的方式完成Post所有的业务逻辑

17 完成用户的显示
用户的查询
- 页面上的数据来自于后台两张表及以上
- 在页面上迭代数据的数据结构和hibernate的持久化类的结构是一样的，但是要找到核心表
要注意的问题：
User中的Department department和Set posts的懒加载问题。
解决方法是采用OpenSessionInView的方式或者左外连接或者内连接的方式（这时候懒加载无效）

个人评论：真正的模型驱动必须通过getMode方式返回给Struts内部压入栈顶，如果自己写了很多vo，则需要自己手动压入栈顶，使其属性曝光。
也可以在jsp中通过类似department.dname作为标签name属性值，赋值给vo的属性。

21 完成对用户信息的验证
1、导入3个jar包。
json-lib-2.1.jar
struts2-json-plugin-2.1.8.1.jar
struts2-junit-plugin-2.1.8.1.jar
注：<1>打开struts2-json-plugin-2.1.8.1.jar，观察里面的struts-plugin.xml文件，可以看到它定义了一个拦截器和一个结果集json。
<2>因为该包继承了struts-default，所以该包拥有struts2的package为struts-default的功能，所以该包同样适用于属性驱动和模型驱动。
<3>因为是ajax操作，所以不需要刷新页面，所以不需要获取result标签中的内容，所以JSONResult只需要实现Result接口即可。
<4>自定义了一个拦截器，如果客户端向服务器端传递复杂格式的类型，这个时候需要用到拦截器。
<5>在ajax与struts结合的使用中，只要action中有get方法，那么这个属性就会返回给回调函数中的data中，如果一个方法的返回值不需要返回给客户端，最好不要以get方法开头。如果一定要使用get方法，那么不要忘记在get方法上面添加@JSON(Serializable=false)，这时候它就不会包含在回调函数的参数data中了。
重点：如果在使用struts和ajax结合的过程中，如果使用$.post发送一个请求，如果出现错误，那么首先应该把这个请求的连接粘贴到浏览器中执行，看能否执行成功，如果能执行成功，那么说明是js出了问题。否则，说明js和服务器都有可能，这时候，将struts配置文件中的继承json-default改为struts-default，看是否能够跳转到相关的方法执行，如果可以，说明json的包有问题。
注：在导入包之后一定要重新部署，否则，无法生效。
<6>如果返回的是一个代理对象（例如已经添加事务的service对象），而不是数据，这个时候根本处理不了，那么就会报错。这时候就需要在这个代理对象的get方法上加上@JSON(serialize=false)。

1，用户的登录名要唯一，在填写时要同时检测是否可用。
2，新建用户后，密码被初始化为"1234"。
3，密码在数据库中存储的是MD5摘要（不是存储明文密码）。
4，用户登录系统后可以使用“个人设置→修改密码”功能修改密码。
5，新建用户后，会自动指定默认的头像。用户可以使用“个人设置→个人信息”功能修改自已的头像
6，修改用户信息时，登录名不可修改。
22 学习使用zTree（一次性全部加载）
1、zTree的加载
<1>加载三个文件
jquery-1.4.2.js
jquery-ztree-2.5.js
zTreeStyle.css
<2>在页面上设置树的容器
找到页面上的一个对象，class属性为’tree’。
<3>树的容器调用zTree方法把生成的树挂在容器上。
<4>细节
setting的配置是用来描述树的整体的特性。
zNodes描述树上的每一个节点。
isParent
描述当前节点是否为子节点
zTree会自动根据该节点是否有子节点，来判断isParent的值。
如果没有子节点，则isParent的值为false。
如果有子节点，则isParent的值为true。
为了保证该节点肯定是父节点，可以直接设置其值为true。
name 节点的名称
id 是根据treeNodeKey定义的。
2、具体步骤
<1>首先将相关的js文件和css文件导入。然后在页面上进行引用。并且设置zTree的容器
<%@ page language =“java” import=“java.util.*” pageEncoding=“UTF-8” %>
<2>写持久化类、映射文件并且导入到hibernate.cfg.xml中。

执行结果：
24 设置权限的初始化部分
1、设置权限五步骤
<1>显示DIV
<2>动态的实现用户名称
<3>全选复选框功能的实现
<4>显示菜单树
<5>保存功能（建立用户和权限之间的关系）
2、具体步骤：
<1>事件的声明
当整个页面加载的时候，声明事件
<2>数据的传递（传递用户的id和menuItemList，插入到数据库）
<3>业务逻辑功能

<1>设置全选checkbox为不可编辑状态
<2>权限树加载完毕之后，再设置为可编辑状态。
<3>并且判断是不是所有的节点选中了，如果选中了，则全选checkbox也设置为选中，否则，设置为未选中。

27 改变选中某个checkbox的影响逻辑
<1>改变zTree的checkbox的选中与未选中的影响逻辑：被选中之后，则父节点被选中，子节点无影响。但是如果解除选中，则父节点无影响，子节点全部改为未选中状态。
<2>这时候可以利用checkType改变这个影响逻辑，但是一旦改变之后又会影响全选checkbox的逻辑，所以必须在全选checkbox之前再把checkType改回去。
<3>最后要解决的一个问题是，如果子节点如果并没有完全选中，那么全选checkbox也要做出相应的改变。

执行结果：
成功插入数据：
但是当再点击超链接的时候，就看不到菜单了。
这时候有三种方案解决问题，一种是在MenuItemAction中的showAllMenuItems方法中设置User为null。
第二种是在MenuItem中在User属性上打上@JSON标记。
以上这两种方法都相当于将User属性过滤掉。就不会出现懒加载的问题了。
第三种是使用inner join或者lefter outer join一次性将所有的内容加载出来。这样就避免了懒加载，但是这时候仍然会失败，因为User中还有Posts这个Set类型属性，所以依然会出现懒加载问题，这时候也必须按照以上三种方式之一再处理一次。
29 用户可用菜单的回显
如果一个treeNode的checked属性设置为true，那么这个菜单就会选中。所以需要给MenuItem设置一个checked属性。
