114020_java-SSH2-Struts2.1、Spring3.0、Hibernate3.3大框架整合详细图解.docx

1.创建项目
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：

2为项目添加Struts能力
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>
3.为项目添加Spring能力
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

4.为项目添加Hibernate能力
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

7.搭建项目结构（分包）
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）

8.搭建项目结构（model、dao生成）
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
<beanid="UsersDAO"class="app.dao.UsersDAO">
<propertyname="sessionFactory">
<refbean="sessionFactory"></ref>
</property>
</bean>
9.搭建项目结构（service、web编写）
a)编写service层代码，创建IUsersService接口和UsersService实现类，编写CRUD的方法。
packageapp.service;
importjava.util.List;
importapp.model.Users;
public interface IUsersService {
public List<Users>findAll();
public List<Users>findByName(String uname);
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,Stringupass);
}
packageapp.service;
importjava.util.List;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
importapp.dao.IUsersDAO;
importapp.dao.UsersDAO;
importapp.model.Users;
public class UsersService implements IUsersService {
private static final Logger log = LoggerFactory.getLogger(UsersService.class);
privateIUsersDAOusersDAO=null;
public void setUsersDAO(IUsersDAOusersDAO) {
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() {
returnusersDAO.findAll();
}
public List<Users>findByName(String uname) {
returnusersDAO.findByUname(uname);
}
public Users findByUid(Integer uid) {
returnusersDAO.findById(uid);
}
public Users login(String uname, String upass) {

List list = usersDAO.findByUname(uname);
if(null==list||list.size()==0)
return null;
Users u=(Users) usersDAO.findByUname(uname).get(0);
if(null==u)
return null;
if(uname.equals(u.getUname())&&upass.equals(u.getUpass()))
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
packageapp.web;
importjava.util.ArrayList;
importjava.util.List;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
importorg.springframework.context.ApplicationContext;
importapp.model.Users;
importapp.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
privateIUsersServiceusersService=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.getUname(), u.getUpass());
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(IUsersServiceusersService) {
this.usersService = usersService;
}
public Users getU() {
return u;
}
public void setU(Users u) {
this.u = u;
}
public List<Users>getUserList() {
returnuserList;
}
public void setUserList(List<Users>userList) {
this.userList = userList;
}
public Integer getUid() {
returnuid;
}
public void setUid(Integer uid) {
this.uid = uid;
}
}
10.搭建项目结构（配置文件编写）
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：
<?xmlversion="1.0"encoding="UTF-8"?>
<beansxmlns="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
<beanid="UsersDAO"class="app.dao.UsersDAO">
<propertyname="sessionFactory">
<refbean="sessionFactory"></ref>
</property>
</bean>
<beanid="UsersService"class="app.service.UsersService">
<propertyname="usersDAO"ref="UsersDAO"/>
</bean>
<beanid="UsersAction"class="app.web.UsersAction">
<propertyname="usersService"ref="UsersService"/>
</bean>
增加事务处理机制
<!--配置事务管理器-->
<beanid="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<propertyname="sessionFactory">
<refbean="sessionFactory"/>
</property>
</bean>
<!--配置事务的传播特性-->
<tx:adviceid="txAdvice"transaction-manager="transactionManager">
<tx:attributes>
<tx:methodname="save*"propagation="REQUIRED"/>
<tx:methodname="update*"propagation="REQUIRED"/>
<tx:methodname="delete*"propagation="REQUIRED"/>
<tx:methodname="add*"propagation="REQUIRED"/>
<tx:methodname="del*"propagation="REQUIRED"/>
<tx:methodname="*"read-only="true"/>
</tx:attributes>
</tx:advice>
<!—哪些类的哪些方法参与事务-->
<aop:config>
<aop:pointcutid="allServiceMethod"expression="execution(* app.service.*.*(..))"/>
<aop:advisorpointcut-ref="allServiceMethod"advice-ref="txAdvice"/>
</aop:config>
b)配置Struts.xml
<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEstrutsPUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.1//EN""http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<constantname="struts.objectFactory"value="spring"></constant>
<packagename="usermanage"extends="struts-default">
<actionname="addUser"class="UsersAction"method="addUser">
<resultname="success"type="redirect">listUser.action</result>
<resultname="error">/error.jsp</result>
</action>
<actionname="editUser"class="UsersAction"method="editUser">
<resultname="success">/user/user_edit.jsp</result>
</action>
<actionname="updateUser"class="UsersAction"method="updateUser">
<resultname="success"type="redirect">listUser.action</result>
<resultname="error">/error.jsp</result>
</action>
<actionname="delUser"class="UsersAction"method="delUser">
<resultname="success"type="redirect">listUser.action</result>
<resultname="error">/error.jsp</result>
</action>
<actionname="listUser"class="UsersAction"method="listUser">
<resultname="success">/user/user_list.jsp</result>
</action>
<actionname="login"class="UsersAction"method="login">
<resultname="success">/index.jsp</result>
<resultname="input">/login.jsp</result>
<resultname="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>
11.搭建项目结构（页面代码）
a)页面关键代码
User_add.jsp
<s:formaction="addUser">
<tableborder="1">
<tr><s:textfieldlabel="用户名"name="u.uname"></s:textfield></tr>
<tr><s:textfieldlabel="密码"name="u.upass"></s:textfield></tr>
<tr><tdcolspan="2"><s:submitvalue="保存"></s:submit></td></tr>
</table>
</s:form>
User_edit.jsp
<s:formaction="updateUser">
<tableborder="1">
<s:hiddenname="u.uid"></s:hidden>
<tr><s:textfieldlabel="用户名"name="u.uname"></s:textfield></tr>
<tr><s:textfieldlabel="密码"name="u.upass"></s:textfield></tr>
<tr><tdcolspan="2"><s:submitvalue="保存"></s:submit></td></tr>
</table>
</s:form>
User_list.jsp
<tableborder="1">
<tr><td>编号</td><td>用户名</td><td>密码</td><td>操作</td></tr>
<s:iteratorvalue="userList">
<tr>
<td>${uid}</td>
<td>${uname }</td>
<td>${upass }</td>
<td><ahref='<s:urlaction="editUser"><s:paramname="uid"value="uid"/></s:url>'>修改</a>&nbsp;
<aonclick="return confirm('确定要删除吗？');"href='<s:urlaction="delUser"><s:paramname="uid"value="uid"/></s:url>'>删除</a></td>
</tr>
</s:iterator>
</table>
Login.jsp
<s:formaction="login">
<tableborder="1">
<tr><s:textfieldlabel="用户名"name="u.uname"></s:textfield></tr>
<tr><s:textfieldlabel="密码"name="u.upass"></s:textfield></tr>
<tr><tdcolspan="2"><s:submitvalue="登录"></s:submit></td></tr>
</table>
</s:form>
12.测试运行
http://localhost:8080/ssh/login.jsp

1.异常排除
执行hql查询时发现异常java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I
原因是由于strut2类库中包含antlr-2.7.2.jar而hibernate使用antlr-2.7.6.jar，版本冲突导致的，查看tomcat发布目录lib文件夹下发现同时存在这两个文件，删除antlr-2.7.2.jar即可
HTTP Status 500 -
