## MySQL语句（DCL） ##

1、创建用户

语法：

CREATE  USER 用户名@地址  IDENTIFIED BY  '密码';

CREATE  USER user1@localhost  IDENTIFIED BY  '123';

CREATE  USER user2@'%'  IDENTIFIED  BY  '123';

\*表示user2用户可以在任何主机上访问本地的数据库

2　给用户授权  
语法：  
GRANT 权限1, … , 权限n ON 数据库.\* TO 用户名@IP  
GRANT CREATE,ALTER,DROP,INSERT,UPDATE,DELETE,SELECT ON mydb1.\* TO user1@localhost;  
GRANT ALL ON mydb1.\* TO user2@’%’;  
3　撤销授权  
语法：  
REVOKE权限1, … , 权限n ON 数据库.\* FORM 用户名  
REVOKE CREATE,ALTER,DROP ON mydb1.\* FROM user1@localhost;  
4　查看用户权限  
语法：  
SHOW GRANTS FOR 用户名  
SHOW GRANTS FOR user1@localhost;  
5　删除用户  
语法：  
DROP USER 用户名  
DROP USER user1@localhost;  
6　修改用户密码  
语法：  
Use mysql;  
UPDATE USER SET PASSWORD=PASSWORD(‘密码’) WHERE User=’用户名’;  
FLUSH PRIVILEGES;  
UPDATE USER SET PASSWORD=PASSWORD('1234') WHERE User='user2';

FLUSH PRIVILEGES;

一、 项目本地导入  
MyEclipse 新建 web project ， 覆盖对应 src 和 WebRoot   
Eclipse 新建 Dynamic web project ， 覆盖src ， 将WebRoot 中内容复制 WebContent 目录  
JavaEE 企业级应用软件，布局经常采用 Frameset ， 左侧菜单树使用Dztree js组件制作的   
  
目标功能 ：  
1、 登陆  
2、 添加用户 （简历上传）  
3、 组合条件 员工信息列表查询   
4、 员工信息详情查看（简历下载）  
5、 员工信息删除  
6、 员工信息编辑  
7． 异常处理  
8.  登录校验  
\--------------------------------------------------------------  
二、 数据库设计   
\#新建数据库  
create database struts2exec;  
  
\#创建用户   
create user struts2@localhost identified by 'struts2';  
\#授权  
grant all on struts2exec.\* to struts2@localhost;  
\*\*\*\*\* Oracle和MySQL 作为应用数据库区别  
mysql存在数据库概念，在企业开发中，针对一个项目创建一个单独数据库，创建单独用户， 为用户授予数据库权限 ，oracle 一个数据库就是一个服务，在这个库中可以存在很多用户，每个用户有单独表空间 ，针对一个项目，只需要创建一个用户  
\#用户表  
CREATE TABLE S\_User(  
userID INT  NOT NULL AUTO\_INCREMENT, \#主键ID  
userName VARCHAR(50)   NULL,  \#用户姓名  
logonName VARCHAR(50)   NULL, \#登录名  
logonPwd VARCHAR(50)  NULL,   \#密码\#  
sex VARCHAR(10)  NULL,        \#性别（例如：男，女）  
birthday VARCHAR(50) NULL,    \#出生日期  
education VARCHAR(20)  NULL,  \#学历（例如：研究生、本科、专科、高中）  
telephone VARCHAR(50)  NULL,  \#电话   
interest VARCHAR(20)  NULL,   \#兴趣爱好（例如：体育、旅游、逛街）  
path VARCHAR(500)  NULL,      \#上传路径（path路径）  
filename VARCHAR(100)  NULL,  \#上传文件名称（文件名）  
remark VARCHAR(500)  NULL,    \#备注  
PRIMARY KEY (userID)  
);  
\#初始化数据：默认用户名和密码是admin  
INSERT INTO s\_user (userID,userName,logonName,logonPwd) VALUES (1,'超级管理员','admin','admin');  
\---------------------------------------------------------------------------------------  
三、 搭建开发环境   
struts2 + javabean + DAO + C3P0 + DBUtils + MySQL   
导入jar包 和 配置文件   
创建包结构  
cn.itcast.user.domain  
cn.itcast.user.dao  
cn.itcast.user.service  
cn.itcast.user.web.action  
cn.itcast.user.utils  
=======================================================================================  
功能实现:  
1.登录操作  
1.使用struts2提供的表单标签来改造页面。  
WebRoot/login/login.jsp  
<form>-------------------<s:form>  
<input type="text">------<s:textfield>  
<input type="password">---<s:password>  
<input type="submit">-----<s:submit>  
<input type="reset">------<s:reset>  
在struts2的doc下有一个tag-reference.html.  
1.改造form  
<s:form id="loginAction\_home" name="form1" action="user\_login" namespace="/" target="\_parent" method="post">  
2.改造登录名  
<s:textfield name="logonName" value="" id="logonName" cssClass="text" cssStyle="width: 160px;"/>  
3.改造登录密码  
<s:password  name="logonPwd" id="logonPwd" cssClass="text" cssStyle="width: 160px;"/>  
密码框默认不回显示.需要设置属性showPassword="true"  
4.<s:submit name="submit" value="登录" cssClass="buttoninput"/>  
5.<s:reset name="reset" value="取消" cssClass="buttoninput"/>  
  
注意:struts2中的表单标签，有默认的主题xhtml.如果不想要添加任何修饰，只需要将主题修改为simple.  
问题:怎样设置主题  
   1.全局  
在struts.xml文件中配置一个常量   
<constant name="struts.ui.theme" value="simple"></constant>  
   2.局部  
针对于某一个form.  
<s:form theme="simple">  
   3.局部  
可以给任意的表单组件去指定theme属性值。  
2.需要使用xml配置方式对数据进行校验。  
用户名 非空，3-12位  
密码  非空   
  
1.在UserAction所在包下创建一个UserAction-validation.xml  
2.在xml文件中添加dtd约束  
<!DOCTYPE validators PUBLIC  
"-//Apache Struts//XWork Validator 1.0.3//EN"  
"http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">  
3.对属性进行校验  
<field name="logonName">  
   <field-validator type="requiredstring">  
<message>用户名不能为空</message>  
</field-validator>  
<field-validator type="stringlength">  
<param name="maxLength">12</param>  
<param name="minLength">3</param>  
<message>用户名长度必须在$\{minLength\}到$\{maxLength\}之间</message>  
</field-validator>  
</field>  
<field name="logonPwd">  
<field-validator type="requiredstring">  
<message>密码不能为空</message>  
</field-validator>  
</field>  
在页面上通过<s:fielderror>  
  
3.登录成功，将用户存储到session，在页面上显示用户。  
top.jsp   $\{user.userName \} 显示当前登陆用户   
\----------------------------------------------------------------------------------------  
2.查询功能--查询全部  
登录成功后，跳转到home.jsp页面。home.jsp页面使用了frameset布局。  
它的左边(left.jsp)页面使用了dtree,来展示。有一个连接用户管理，  
当点击它时，打开了list.jsp页面。  
  
问题:点击用户管理，应该直接打开list.jsp页面？  
当点击用户管理时，应该访问UserAction中的list方法，查询出所有的List<User>  
在跳转到list.jsp页面，展示出所有用户。  
实现:  
1.修改left.jsp页面上的用户管理的连接。  
原来:d.add(3,2,'用户管理','$\{pageContext.request.contextPath\}/user/list.jsp','','mainFrame');  
修改后  
d.add(3,2,'用户管理','$\{pageContext.request.contextPath\}/user\_list','','mainFrame');  
2.在list方法中调用service,dao完成查询操作  
得到一个List<User> users;  
我们将List<User> users声明成成员变量，提供get/set方法，  
这样，集合就会自动的压入到valueStack中.  
问题:  
1.返回SUCCESS问题   因为我们的配置是使用了通配符，一个配置对应多个请求。  
这时，有可能有多种情况都返回SUCCESS,所以我们修改.  
登录成功返回  login\_success   查询所有成功  list\_success.  
2.关于查询操作时，校验的配置文件会执行。  
原因:我们之前配置文件名称叫  UserAction-validation.xml，它会对UserAction下所有方法校验。  
解决:将其修改为   UserAction-user\_login-validation.xml 这就只会对user\_login进行校验。  
  
3.查询成功跳转到了 list.jsp，在页面上展示信息.  
\------------------------------------------------------------------------------------------------------  
3.添加员工  
1.对add.jsp页面上html标签修改----struts2的表单标签  
1.性别  
原标签  
<input type="radio" name="sex" id="sex男" value="男"/><label for="sex男">男</label>  
<input type="radio" name="sex" id="sex女" value="女"/><label for="sex女">女</label>  
struts2标签:  
<s:radio list="\{'男','女'\}" name="sex" id="sex" value="%\{'男'\}"/>  
  
2.学历  
原标签:  
<select name="education" id="education">  
<option value=""  
selected="selected"  
>--选择学历--</option>  
<option value="博士">博士</option>  
<option value="硕士">硕士</option>  
<option value="研究生">研究生</option>  
<option value="本科">本科</option>  
<option value="专科">专科</option>  
<option value="高中">高中</option>  
</select>  
struts2标签  
<s:select list="\{'博士','硕士','研究生','本科','专科','高中'\}" name="education" id="education" headerKey="" headerValue="--选择学历--"></s:select>  
3.兴趣爱好  
<s:checkboxlist list="\{'看电影','旅游','健身','购物','睡觉'\}" name="interest"/>  
4.上传  
<s:file name="upload" size="30" value="" id="userAction\_save\_do\_upload"/>  
5.文本域  
<s:textarea name="remark" cols="30" rows="3" id="userAction\_save\_do\_remark" cssStyle="WIDTH: 96%"/>  
  
  
  
  
2.添加数据的校验  
在UserAction类所在包下创建一个 UserAction-user\_add-validation.xml  
  
3.完成添加操作(上传)  
  
  
问题:怎样将要添加的信息在action中获取到?  
  
在UserAction类中有一个  private User user=new User();  
我们又声明了  
private File upload;  
private String uploadContentType;  
private String uploadFileName;  
  
添加的用户信息，除了上传文件的信息，其它的都封装到了user对象中。  
而上传文件信息在三个属性上封装。  
  
对于我们添加用户还需要有下列信息:  
userID----->自动增长  
path------->人为指定。  
简历不允许被浏览器端直接访问。  
d:/upload下.  
上传简历，保存时的重名问题.  
d:/upload/随机名.  
filename=真实名  
  
  
对于我们上面操作，因为多个action在同一个配置中(使用了通配符).  
多个请求操作时，可能都需要跳转到input视图。但是它们跳转的页面  
不一样，怎样处理?  
  
  
可以 通过 @InputConfig注解，改为校验失败后 跳转视图   
\------------------------------------------------------------------------------------  
4.条件查询  
1.在list.jsp页面修改查询组件  
  
  
是否上传简历  
<s:select list="\#\{'1':'有','2':'无'\}" name="isUpload" id="isUpload" headerKey="0" headerValue="--请选择--"></s:select>  
  
  
  
  
2.添加校验  
3.完成条件查询操作  
问题:是否上传简历，怎样在action中获取？  
需要在User中添加一个属性  String isUpload  
在dao中怎样根据条件查询?  
1.sql语句生成  
2.参数怎样传递?  
创建一个List<Object>,在每一次判断时，直接将参数添加到集合中，  
最后将集合转换成Object\[\]，做为参数传递到query方法中。  
  
String sql = "select \* from s\_user where 1=1 ";  
List<Object> params=new ArrayList<Object>();  
String username = user.getUserName();  
if (username != null && username.trim().length() > 0) \{  
sql += " and userName like ?";  
params.add("%"+username+"%");  
\}  
String sex = user.getSex();  
if (sex != null && sex.trim().length() > 0) \{  
sql += " and sex=?";  
params.add(sex);  
\}  
String education = user.getEducation();  
if (education != null && education.trim().length() > 0) \{  
sql += " and education=?";  
params.add(education);  
\}  
  
  
String isupload = user.getIsUpload();  
if ("1".equals(isupload)) \{  
sql += " and filename is not null";  
\} else if ("2".equals(isupload)) \{  
sql += " and filename is null";  
\}  
  
  
QueryRunner runner = new QueryRunner(DataSourceUtils.getDataSource());  
  
  
return runner.query(sql, new BeanListHandler<User>(User.class),params.toArray());  
\--------------------------------------------------------------------------------------------------  
5.员工删除  
在list.jsp页面上有删除链接，我们只需要将当前用户的id传递到服务器端  
在服务器端根据id删除用户信息。删除完成，在查询一次。  
  
  
1.修改list.jsp页面上删除连接  
原标签:  
<a href="$\{pageContext.request.contextPath\}/user/list.jsp?userID=15">  
<img src="$\{pageContext.request.contextPath\}/images/i\_del.gif" width="16" height="16" border="0" style="CURSOR: hand">  
</a>  
使用struts2标签修改  
第一种方式  
<s:a href="路径">  
第二种方式  
<s:a action="" namespace="">  
<s:param name="" value="">  
</s:a>  
第三种方式:  
<s:url>标签来定义一个路径  
<s:a href="url">来导入url值。  
  
  
<s:url namespace="/" action="user\_del" var="delUrl">  
<s:param name="id" value="%\{\#u.userID\}"/>  
</s:url>  
  
  
<s:a href="%\{\#delUrl\}">  
<img src="$\{pageContext.request.contextPath\}/images/i\_del.gif" width="16" height="16" border="0" style="CURSOR: hand">  
</s:a>  
  
  
  
  
2.完成删除操作  
  
  
问题:如果用户有简历，删除用户时，也要将简历删除。  
1.先查询出用户。  
2.判断user.getPath()!=null  
new File(user.getPath()).delete();  
\---------------------------------------------------------------------------------------  
6.员工详细信息查看  
在list.jsp页面，有查看客户详细信息连接。  
<s:url namespace="/" action="user\_findById" var="findByIdUrl">  
<s:param name="userID" value="%\{\#u.userID\}"/>  
</s:url>  
<s:a href="%\{\#findByIdUrl\}">  
<img src="$\{pageContext.request.contextPath\}/images/button\_view.gif" border="0" style="CURSOR: hand">  
</s:a>  
  
查询出用户信息(user),需要在view.jsp页面展示   
  
在页面上展示时，我们不能使用valueStack栈顶的user对象，而要  
使用压入的action的getModel方法，重新得到user对象去获取信息。  
\-----------------------------------------------------------------------------------------  
7.员工简历下载(作业)  
在view.jsp页面上展示的员工信息包含了简历，它是一个连接，点击它，实现员工简历下载。  
  
  
在<result name="download\_success" type="stream">  
<param name="contentType">$\{contentType\}</param>  
<param name="contentDisposition">attachment;filename=$\{downloadFilename\}</param>  
<param name="inputStream">$\{inputStream\}</param>  
</result>  
\-----------------------------------------------------------------------------------------  
8.员工信息修改  
1.查询  
<a href="$\{pageContext.request.contextPath\}/user/edit.jsp?userID=15">  
<img src="$\{pageContext.request.contextPath\}/images/i\_edit.gif" border="0" style="CURSOR: hand">  
</a>  
<s:url namespace="/" action="user\_updateForFind" var="editUrl">  
<s:param name="userID" value="%\{\#u.userID\}"/>  
</s:url>  
<s:a href="%\{\#editUrl\}">  
<img src="$\{pageContext.request.contextPath\}/images/i\_edit.gif" border="0" style="CURSOR: hand">  
</s:a>  
查询出user对象，跳转到edit.jsp页面，展示用户信息。  
2.修改  
修改就是一个上传操作:  
问题:在修改时，关于用户简历的处理?  
1.原来没有  修改也没有。---不管  
2.原来没有  修改有了    ----处理  
3.原来有    修改没有了 -----不管  
4.原来有    修改也有.  -----处理(将旧的删除)  
  
修改前必须先查询出用户。  
==================================================================================

9.登陆校验拦截器   
功能:用户只有登录成功后，才可以进行操作.  
  
做一个Interceptor.判断用户是否登录了。（登录标志session中有user）  
自定义Interceptor步骤:  
1.创建一个类，实现Interceptor接口  
2.重写方法完成功能  
3.在struts.xml文件注册  
4.在action中引入  
=================================================================================  
10.struts2 提供的异常处理  
对于action中的操作，出现问题，直接抛出自定义异常。  
在struts.xml文件中  
<global-exception-mappings>  
<exception-mapping result="login"  
exception="cn.itcast.user.exception.FindByIdException"></exception-mapping>  
</global-exception-mappings>  
这就可以让特定的异常，跳转到自定的页面。  
原理:  
struts2,默认加载的18个拦截器的第一个是exception这个拦截器，它没有做任何操作，  
直接放行，，只是它将 invocation.invoke()操作使用try-catch进行了处理。  
其它的拦截器，或是action只要向外抛出异常，exception拦截器就会将其捕获。
