打开Myeclipse8.6，新建web工程，命名为ssh，点击完成。
获得目录结构如下：
????a)右键点击项目，选择MyEclipse->Add Struts Capabilities，或者点击菜单栏中MyEclipse->Project Capabilities->Add Struts Capabilities。
b)选择struts2.1版本
c)点击下一步，选择Struts Core(核心库)和Struts 2 Spring(包含集成Spring插件)的两个最基本库，其他根据需要可以添加。
d)点击完成，添加后的项目多了一个Struts.xml（用于配置action），web.xml中添加了核心过滤器的配置。
<filter> ????<filter-name>struts2</filter-name> ????<filter-class> ????????org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter ????</filter-class> </filter> <filter-mapping> ????<filter-name>struts2</filter-name> ????<url-pattern>/*</url-pattern> </filter-mapping> |
?
a)右键点击项目，选择MyEclipse->Add Spring Capabilities，或者点击菜单栏中MyEclipse->Project Capabilities->Add Spring Capabilities。
b)选择Spring3.0版本，类库选择 Spring 3.0 AOP、Spring 3.0 Core、Spring 3.0 Persistence Core、Spring 3.0 Persistence JDBC、Spring 3.0 Web 5个库，并勾选复制到本地WEB-INF/lib目录。
c)点击下一步，默认配置不需修改。
d)点击完成，查看添加Spring后的项目，增加了applicationContex.xml文件
a)右键点击项目，选择MyEclipse->Add Hibernate Capabilities，或者点击菜单栏中MyEclipse->Project Capabilities->Add Hibernate Capabilities。
b)选择Hibernate3.3版本，如果要使用注记可选中启用annotation，但是会对后续自动生成实体类造成麻烦，不选就是用xml文件形式进行实体类映射，默认勾选Hibernate 3.3 Annotation & Entity Manager、Hibernate 3.3 Core Libraries两个类库，复制jar文件到本地WEB-INF/lib文件夹下。
c)点击下一步，选择使用Spring的配置文件applicationContext.xml，这样就不会生成hibernate.cfg.xml，生成与否看个人习惯。
d)点击下一步，选择已经存在的applicationContext.xml文件的位置以及创建sessionFactory的名字
e)下一步，选择已经建立好的数据库连接mydb
f)点击下一步，取消勾选，不生成HibernateSessionFactory类
g)点击完成，查看工程，applicationContext.xml文件中增加了数据库连接的配置，包括datasource和sessionFactory
环境搭建完毕
a)创建包结构：model（实体类）、dao（数据库访问类）、service（业务逻辑类）、web（控制类）
数据库名：bai
建立users表 ，数据库脚本
CREATE TABLE users( id int(11) NOT NULL auto_increment , username varchar(50) default NULL, password varchar(50) default NULL, PRIMARY KEY (id) ); |
?
利用Myeclipse生成model和dao（最好自己构建可以减少冗余代码）
转到MyEclipse数据库浏览视图下，双击mydb进行连接
右键点击users表，选择Hibernate反向工程
选择生成目录为app.model，勾选创建POJO即创建表对应的Javabean，同时创建映射文件hbm.xml，勾选更新hibernate配置，勾选创建spring dao。
下一步，选择id生成策略为native，因为users主键自增，或者在下一步中选择也可以
点击完成，回到代码视图查看工程变化，model包下面增加了Users.java、UsersDAO.java、Users.hbm.xml三个文件
将UsersDAO移动到dao包中，并抽出接口IUsersDAO
因为位置移动需要修改applicationContex.xml中的配置
<bean id="UsersDAO" class="app.dao.UsersDAO"> ????<property name="sessionFactory"> ????????<ref bean="sessionFactory"></ref> ????</property> </bean> |
a)编写service层代码，创建IUsersService接口和UsersService实现类，编写CRUD的方法。
IUsersService接口 package app.service; import java.util.List; import app.model.Users; public interface IUsersService { ????public List<Users>findAll(); ????public List<Users> findByUsername (String uname);v ????public Users findByUid(Integer uid); ????public void addUsers(Users u) throws Exception ; ????public void updateUsers(Users u) throws Exception ; ????public void delUsers(Integer uid) throws Exception ; ????public Users login(String uname,String upass); } UsersService实现类 package app.service; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import app.dao.IUsersDAO; import app.dao.UsersDAO; import app.model.Users; ? public class UsersService implements IUsersService { ????private static final Logger log = LoggerFactory.getLogger(UsersService.class); ????private IUsersDAO usersDAO=null; ????public void setUsersDAO(IUsersDAO usersDAO) { ????????this.usersDAO = usersDAO; ???? } ????public void addUsers(Users u) throws Exception { ????????usersDAO.save(u);???????? ???? } ????public void delUsers (Integer uid) throws Exception { ????????usersDAO.delete(findByUid(uid)); ???? } ????public List<Users> findAll() { ????????return usersDAO.findAll(); ???? } ????public List<Users> findByUsername(String uname) { ????????return usersDAO.findByUsername(uname); ???? } ????public Users findByUid(Integer uid) { ????????return usersDAO.findById(uid); ???? } ????public Users login(String uname, String upass) { ???????? ???????? List list = usersDAO.findByUsername(uname); ????????if(null==list||list.size()==0) ????????????return null; ???????? Users u=(Users) usersDAO.findByUsername(uname).get(0); ????????if(null==u) ????????????return null; ????if(uname.equals(u.getUsername())&&upass.equals(u.getPassword())) ????????????return u; ????????else ????????????return null; ???? } ????public void updateUsers (Users u) throws Exception { ????????usersDAO.attachDirty(u); ???? } } |
b)编写web层UsersAction代码，用于对用户增删改查进行处理
package app.web; import java.util.ArrayList; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.ApplicationContext; import app.model.Users; import app.service.IUsersService; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; public class UsersAction extends ActionSupport{ ????private static final Logger log = LoggerFactory.getLogger(UsersAction.class); ???? private Integer uid=new Integer(0);//用于修改删除时传参数 ???? private Users u=new Users();//用于增改 ???? private List<Users> userList=new ArrayList<Users>();//用于查询 ????private IUsersService usersService=null;???? ????public String addUser() throws Exception{ ????????try { ????????????usersService.addUsers(u); ???????? } catch (Exception e) { ????????????log.error("保存用户错误",e); ????????????return ERROR; ???????? } ????????return SUCCESS; ???? }???? ????public String listUser() throws Exception{???????? ????????userList=usersService.findAll(); ????????return SUCCESS; ???? } ????public String editUser() throws Exception{ ????????try { ???????????? u=usersService.findByUid(uid); ???????? } catch (Exception e) { ????????????log.error("修改用户错误",e); ????????????return ERROR; ???????? } ????????return SUCCESS; ???? } ????public String updateUser() throws Exception{ ????????try { ????????????usersService.updateUsers(u); ???????? } catch (Exception e) { ????????????log.error("更新用户错误",e); ????????????return ERROR; ???????? } ????????return SUCCESS; ???? }???? ????public String delUser() throws Exception{ ????????try { ????????????usersService.delUsers(uid); ???????? } catch (Exception e) { ????????????log.error("删除用户错误",e); ????????????return ERROR; ???????? } ????????return SUCCESS; ???? }???? ????public String login() throws Exception{ ????????try { ???????????? Users loginUser=usersService.login(u.getUsername(), u.getPassword()); ????????????if(null!=loginUser){ ????????????????ActionContext context=ActionContext.getContext(); ????????????????context.getSession().put("LOGINUSER",loginUser); ????????????????return SUCCESS; ???????????? } ???????? } catch (Exception e) { ????????????log.error("登录查询错误",e); ????????????return ERROR; ???????? } ????????return INPUT; ???? }???? ????public void setUsersService(IUsersService usersService) { ????????this.usersService = usersService; ???? }???? ????public Users getU() { ????????return u; ???? } ????public void setU(Users u) { ????????this.u = u; ???? }???? ????public List<Users>getUserList() { ????????return userList; ???? } ????public void setUserList(List<Users>userList) { ????????this.userList = userList; ???? } ????public Integer getUid() { ????????return uid; ???? } ????public void setUid(Integer uid) { ????????this.uid = uid; ???? } } |
a)补充applicationContext.xml配置文件，装配注入关系和事务处理
增加spring配置文件节点的命名空间，否则事务处理节点不识别：
<?xml?version="1.0"?encoding="UTF-8"?> <beans?xmlns="http://www.springframework.org/schema/beans" ???????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ???????xmlns:context="http://www.springframework.org/schema/context" ???????xmlns:aop="http://www.springframework.org/schema/aop" ???????xmlns:tx="http://www.springframework.org/schema/tx" ???????xsi:schemaLocation=" ???????http://www.springframework.org/schema/beans?http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ???????http://www.springframework.org/schema/aop?http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ???????http://www.springframework.org/schema/tx?http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ???????http://www.springframework.org/schema/context?http://www.springframework.org/schema/context/spring-context-3.0.xsd"> |
增加装配关系
<bean?id="UsersDAO"?class="app.dao.UsersDAO"> ????<property?name="sessionFactory"> ???????<ref?bean="sessionFactory"></ref> ????</property> ????</bean> <bean?id="UsersService"?class="app.service.UsersService"> ????<property?name="usersDAO"?ref="UsersDAO"/> </bean> <bean?id="UsersAction"?class="app.web.UsersAction"> ????<property?name="usersService"?ref="UsersService"/> </bean> |
增加事务处理机制
? ??<!--配置事务管理器--> <bean?id="transactionManager"????????class="org.springframework.orm.hibernate3.HibernateTransactionManager"> ????<property?name="sessionFactory"> ????????<ref?bean="sessionFactory"/> ????</property> </bean> <!--配置事务的传播特性--> <tx:advice?id="txAdvice"?transaction-manager="transactionManager"> ????<tx:attributes> ????????<tx:method?name="save*"?propagation="REQUIRED"/> ????????<tx:method?name="update*"?propagation="REQUIRED"/> ????????<tx:method?name="delete*"?propagation="REQUIRED"/> ????????<tx:method?name="add*"?propagation="REQUIRED"/> ????????<tx:method?name="del*"?propagation="REQUIRED"/> ????????<tx:method?name="*"?read-only="true"/> ????</tx:attributes> </tx:advice> <!--?哪些类的哪些方法参与事务?--> <aop:config> ????????<aop:pointcut?id="allServiceMethod"?expression="execution(*?app.service.*.*(..))"/> ????????<aop:advisor?pointcut-ref="allServiceMethod"?advice-ref="txAdvice"/> </aop:config> ????</beans> |
?
b)配置Struts.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <constant name="struts.objectFactory" value="spring"></constant> <package name="usermanage" extends="struts-default"> <action name="addUser" class="UsersAction" method="addUser"> <result name="success" type="redirect">listUser.action</result> <result name="error">/error.jsp</result> </action> <action name="editUser" class="UsersAction" method="editUser"> <result name="success">/user/user_edit.jsp</result> </action> <action name="updateUser" class="UsersAction" method="updateUser"> <result name="success" type="redirect">listUser.action</result> <result name="error">/error.jsp</result> </action> <action name="delUser" class="UsersAction" method="delUser"> <result name="success" type="redirect">listUser.action</result> <result name="error">/error.jsp</result> </action> <action name="listUser" class="UsersAction" method="listUser"> <result name="success">/user/user_list.jsp</result> </action> <action name="login" class="UsersAction" method="login"> <result name="success">/index.jsp</result> <result name="input">/login.jsp</result> <result name="error">/error.jsp</result> </action> </package> </struts> |
c)配置web.xml，设定applicationContex.xml的加载位置，如果放在WEB-INF下则不需要设定，配置监听
?<context-param> ?<param-name>contextConfigLocation</param-name> ????<param-value> ????????classpath:applicationContext.xml ????</param-value> ????</context-param> ????<listener> ????<listener-class> ????????org.springframework.web.context.ContextLoaderListener ????</listener-class> ????</listener> |
a)页面关键代码
User_add.jsp
<body> <s:form action="addUser"> <table border="1"> <tr><s:textfield label="用户名" name="u.uname"></s:textfield></tr> <tr><s:textfield label="密码" name="u.upass"></s:textfield></tr> <tr><td colspan="2"><s:submit value="保存"></s:submit></td></tr> </table> </s:form> </body> |
User_edit.jsp
<body> <s:form action="updateUser"> ????<table border="1"> ????????<s:hidden name="u.uid"></s:hidden> ????????<tr><s:textfield label="用户名" name="u.uname"></s:textfield></tr> ????????<tr><s:textfield label="密码" name="u.upass"></s:textfield></tr> ????????<tr><td colspan="2"><s:submit value="保存"></s:submit></td></tr> ????</table> </s:form> ? </body> |
User_list.jsp
<body> <table border="1"> <tr><td>编号</td><td>用户名</td><td>密码</td><td>操作</td></tr> <s:iterator value="userList"> <tr> <td>${uid}</td> <td>${uname }</td> <td>${upass }</td> <td><a href=‘<s:url action="editUser"><s:param name="uid" value="uid" /></s:url>‘>修改</a> <a onclick="return confirm(‘确定要删除吗？‘);" href=‘<s:url action="delUser"><s:param name="uid" value="uid" /></s:url>‘>删除</a></td> </tr> </s:iterator> </table> </body> |
Login.jsp
<s:form action="login"> ???? <table border="1"> ???? ???? <tr><s:textfield label="用户名" name="u.uname"></s:textfield></tr> ???? ???? <tr><s:textfield label="密码" name="u.upass"></s:textfield></tr> ???? ???? <tr><td colspan="2"><s:submit value="登录"></s:submit></td></tr> ???? </table> </s:form> |
