搭建SSH三大框架WEB项目过程(Struts2.3+Hibernate4.3+Spring4.1)
来源：互联网 发布：淘宝卖家量子监控 编辑：程序博客网 时间：2024/05/16 04:54
我以我做的一个例子来说明框架的搭建过程 ^V^！
项目结构如图：
action：存放Action类，也就是控制类
dao：DAO数据库操作
po：POJO类，也就是持久化类
service：存放Service类
dao类在Service类里调用，然后Service类再到action类里调用
搭建过程
我们先要准备jar价包，这个可以去官网下载
下面是我准备的开发jar价包
然后我为了提高安全性，我将所有的JSP页面放在了WEB-INF下面
然后配置SSH的配置文件
Spring的配置文件代码：
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"> <!-- Spring框架配置文件 --> <!-- 属性注入配置 --> <context:annotation-config/> <!-- 实现数据库配置 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/db_sgdata?useUnicode=true&characterEncoding=UTF-8"></property> <property name="username" value="root"></property> <property name="password" value="111"></property> <property name="maxActive" value="100"></property> <property name="maxIdle" value="60"></property> <property name="maxWait" value="10000"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean> <bean id="hibernateTemplate" class="org.springframework.orm.hibernate4.HibernateTemplate"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="txManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 开启Spring框架的事务管理 ，开启之后@Transaction就可以用了 --> <tx:annotation-driven transaction-manager="txManager"/> <!-- 实现教师信息管理需要配置的Bean --> <bean id="teacherDao" class="com.sgdata.dao.impl.TeacherDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="teacherService" class="com.sgdata.service.impl.TeacherServiceBean"> </bean> <!--scope默认采用的是单例模式，scope="prototype" 可以保证 当有请求的时候都创建一个Action对象，保证Struts的Action线程安全 --> <bean id="teacherAction" class="com.sgdata.action.TeacherInfoManagerAction" scope="prototype"></bean> <bean id="loginCheckAction" class="com.sgdata.action.LoginCheckAction" scope="prototype"></bean> <!-- 实现学生信息管理需要配置的Bean --> <bean id="studentDao" class="com.sgdata.dao.impl.StudentDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="studentService" class="com.sgdata.service.impl.StudentServiceBean"></bean> <bean id="studentAction" class="com.sgdata.action.StudentInfoManagerAction" scope="prototype"></bean> <!-- 实现课程信息管理需要配置的Bean --> <bean id="courseDao" class="com.sgdata.dao.impl.CourseDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="courseService" class="com.sgdata.service.impl.CourseServiceBean"></bean> <bean id="courseAction" class="com.sgdata.action.CourseInfoManagerAction" scope="prototype"></bean> <!-- 实现比赛信息管理需要配置的Bean --> <bean id="matchDao" class="com.sgdata.dao.impl.MatchDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <bean id="matchService" class="com.sgdata.service.impl.MatchServiceBean"></bean> <bean id="matchAction" class="com.sgdata.action.MatchInfoManagerAction" scope="prototype"></bean> </beans>
Struts2的配置文件代码：
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <!-- Struts2框架配置文件 --> <struts> <!-- 配置struts2可以受理的请求扩展名 --> <constant name="struts.action.extension" value="action,do,"></constant> <!-- struts2的package对应于项目的模块 --> <package name="action" extends="struts-default" namespace="/"> <!-- 配置action --> <!-- 登录验证的Action --> <action name="loginAction" class="loginCheckAction"> <result name="success">/WEB-INF/page/admin/index.jsp</result> <result name="input">/WEB-INF/page/admin/login.jsp</result> </action> <!-- SSH项目WEB-INF下面的页面跳转要通过Servlet来实现，这样确实是麻烦了点， 不过安全性就提高上去了，因为放在WEB-INF下面的JSP页面，是不可以直接访问的 --> <action name="indexAction"> <result>/WEB-INF/page/admin/index.jsp</result> </action> <action name="gotoLoginAction"> <result>/WEB-INF/page/admin/login.jsp</result> </action> <!-- 学生信息管理的Action --> <action name="getAllStuInfoAction" class="studentAction" method="getAllInfo"> <result name="success">/WEB-INF/page/admin/student/studentInfoManager.jsp</result> </action> <action name="getStuInfoByIdAction" class="studentAction" method="getInfoById"> <result name="success">/WEB-INF/page/admin/student/studentInfoDetail.jsp</result> </action> <action name="getLearnScoresAction" class="studentAction" method="getLearnScoreById"> <result name="success">/WEB-INF/page/admin/student/studentLearnScores.jsp</result> </action> <action name="getMatchScoresAction" class="studentAction" method="getMatchScoreById"> <result name="success">/WEB-INF/page/admin/student/studentMatchScores.jsp</result> </action> <!-- 教师信息管理的Action --> <action name="getAllTeaInfoAction" class="teacherAction" method="getAllInfo"> <result name="success">/WEB-INF/page/admin/teacher/teacherInfoManager.jsp</result> </action> <action name="getTeachingInfoAction" class="teacherAction" method="getTeachingInfoById"> <result name="success">/WEB-INF/page/admin/teacher/teacherTeaching.jsp</result> </action> <action name="getMatchGuideInfoAction" class="teacherAction" method="getMatchGuideInfoById"> <result name="success">/WEB-INF/page/admin/teacher/teacherMatchGuide.jsp</result> </action> <action name="getCourseStudentsInfoAction" class="teacherAction" method="getCourseStudentsInfoById"> <result name="success">/WEB-INF/page/admin/teacher/teacherCourseStusInfo.jsp</result> </action> <action name="getMatchStudentsInfoAction" class="teacherAction" method="getMatchStudentsInfoById"> <result name="success">/WEB-INF/page/admin/teacher/teacherMatchStusInfo.jsp</result> </action> <!-- 课程管理的Action --> <action name="getAllCourseInfoAction" class="courseAction" method="getAllInfo"> <result name="success">/WEB-INF/page/admin/course/courseManager.jsp</result> </action> <action name="getTeachersInfoAction" class="courseAction" method="getTeachersInfoById"> <result name="success">/WEB-INF/page/admin/course/courseTeachersInfo.jsp</result> </action> <!-- 比赛信息管理的Action --> <action name="getAllMatchInfoAction" class="matchAction" method="getAllInfo"> <result name="success">/WEB-INF/page/admin/match/matchInfoManager.jsp</result> </action> <action name="getStudentsInfoAction" class="matchAction" method="getStudentsInfoById"> <result name="success">/WEB-INF/page/admin/match/matchStudentsInfo.jsp</result> </action> </package> </struts>
Hibernate的配置文件代码：
<?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <!-- Generated by MyEclipse Hibernate Tools. --> <hibernate-configuration> <!-- Hibernate框架配置文件 --> <session-factory> <!-- 配置sql语句可以打印在控制台 --> <property name="show_sql">true</property> <!--创建SessionFactory对象时自动创建数据表 --> <property name="hbm2ddl.auto">update</property> <!-- 配置映射文件 --> <mapping resource="com/sgdata/po/Course.hbm.xml"/> <mapping resource="com/sgdata/po/Deptment.hbm.xml"/> <mapping resource="com/sgdata/po/Match.hbm.xml"/> <mapping resource="com/sgdata/po/Student.hbm.xml"/> <mapping resource="com/sgdata/po/StudentCourse.hbm.xml"/> <mapping resource="com/sgdata/po/StudentMatch.hbm.xml"/> <mapping resource="com/sgdata/po/Teacher.hbm.xml"/> <mapping resource="com/sgdata/po/TeacherCourse.hbm.xml"/> <mapping resource="com/sgdata/po/TeacherMatch.hbm.xml"/> </session-factory> </hibernate-configuration>
前面那些配置文件有包含其它的，这个要根据自己的项目需要去改的^V^
下面以学生信息管理的实现过程进行说明，只说明这个例子哈！
创建POJO实体类：
import java.util.Date; import java.util.HashSet; import java.util.Set; /** * * 学生信息的实体类 * @author Nicky * */ public class Student { /* * 学号 */ private String stuID; /* * 班级 */ private String stuName; /* * 性别 */ private String stuSex; /* * 出生年日 */ private Date stuBirth; /* * 电话 */ private String stuTel; /* * 邮箱 */ private String stuEmail; /* * 专业 */ private String dept; /* * 身份证 */ private String stuIDCard; /* * 班级 */ private String className; /* * 登录密码 */ private String password; /* * 是否是管理员的标志 1表示是，0表示不是 */ private String isManager; public String getStuID() { return stuID; } public void setStuID(String stuID) { this.stuID = stuID; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } public String getStuSex() { return stuSex; } public void setStuSex(String stuSex) { this.stuSex = stuSex; } public Date getStuBirth() { return stuBirth; } public void setStuBirth(Date stuBirth) { this.stuBirth = stuBirth; } public String getStuTel() { return stuTel; } public void setStuTel(String stuTel) { this.stuTel = stuTel; } public String getStuEmail() { return stuEmail; } public void setStuEmail(String stuEmail) { this.stuEmail = stuEmail; } public String getDept() { return dept; } public void setDept(String dept) { this.dept = dept; } public String getStuIDCard() { return stuIDCard; } public void setStuIDCard(String stuIDCard) { this.stuIDCard = stuIDCard; } public String getClassName() { return className; } public void setClassName(String className) { this.className = className; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getIsManager() { return isManager; } public void setIsManager(String isManager) { this.isManager = isManager; } } 配置Student.hbm.xml文件
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.sgdata.po"> <class name="Student" table="tb_students"> <id name="stuID" column="stuID" type="java.lang.String" length="11"> <generator class="assigned"></generator> </id> <property name="stuName" type="java.lang.String" length="30" not-null="true"></property> <property name="stuSex" type="java.lang.String" length="2" not-null="true"></property> <property name="stuBirth" type="java.util.Date" not-null="true"></property> <property name="stuTel" type="java.lang.String" length="20" not-null="true"></property> <property name="stuEmail" type="java.lang.String" length="20" not-null="true"></property> <property name="dept" type="java.lang.String" length="10" not-null="true"></property> <property name="stuIDCard" type="java.lang.String" length="20" not-null="true"></property> <property name="className" type="java.lang.String" length="20" not-null="true"></property> <property name="password" type="java.lang.String" length="10" not-null="true"></property> <property name="isManager" type="java.lang.String" length="1" not-null="false"></property> </class> </hibernate-mapping>
DAO实现
import java.util.List; import com.sgdata.po.Student; public interface StudentDao { /** * 获取所有学生信息 * @return */ public List<Student> getAllStudentInfo(); } public class StudentDaoImpl extends HibernateDaoSupport implements StudentDao { @Resource HibernateTemplate ht; /** * 获取<pre name="code" class="java">import java.util.List; import com.sgdata.po.Student; public interface StudentService { /** * 获取所有学生信息 * @return */ public List<Student> getAllStudentInfo(); } 所有信息 */ public List<Student> getAllStudentInfo() { String sql = "from Student"; List<Student> students = (List<Student>) ht.find(sql); return students; } }Service实现：
import java.util.List; import com.sgdata.po.Student; public interface StudentService { /** * 获取所有学生信息 * @return */ public List<Student> getAllStudentInfo(); } import java.util.List; import javax.annotation.Resource; import org.springframework.transaction.annotation.Transactional; import com.sgdata.dao.StudentDao; import com.sgdata.po.Student; import com.sgdata.service.StudentService; @Transactional(readOnly=false) public class StudentServiceBean implements StudentService { @Resource private StudentDao studentDao; public List<Student> getAllStudentInfo() { return studentDao.getAllStudentInfo(); } } Action实现：
/** * 实现学生信息管理的Action类 * */ public class StudentInfoManagerAction extends ActionSupport { /** * */ private static final long serialVersionUID = 1L; @Resource private StudentService studentService; //页数 int pagenum = 0; //学号 private String stuID; //姓名 private String stuName; //性别 private String stuSex; //出生年月 private String stuBirth; //电话 private String stuTel; //邮箱 private String stuEmial; //系部 private String dept; //身份证 private String stuIDCard; //班级 private String className; //密码 private String password; /** * 学生对象来储存学生信息 */ private Student student; /** * 学生信息的列表 */ private List<Student> studentsInfo; /** * 学生学习成绩的信息列表 */ private List learnScores; /** * 学生比赛成绩的信息列表 */ private List matchScores; public StudentInfoManagerAction(){ //student = new Student(); } public Student getStudent() { return student; } public void setStudent(Student student) { this.student = student; } public void setStudentsInfo(List<Student> studentsInfo){ this.studentsInfo = studentsInfo; } public List<Student> getStudentsInfo() { return studentsInfo; } public List getLearnScores() { return learnScores; } public void setLearnScores(List learnScores) { this.learnScores = learnScores; } public List getMatchScores() { return matchScores; } public void setMatchScores(List matchScores) { this.matchScores = matchScores; } public int getPagenum() { return pagenum; } public void setPagenum(int pagenum) { this.pagenum = pagenum; } public String getStuID() { return stuID; } public void setStuID(String stuID) { this.stuID = stuID; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } public String getStuSex() { return stuSex; } public void setStuSex(String stuSex) { this.stuSex = stuSex; } public String getStuBirth() { return stuBirth; } public void setStuBirth(String stuBirth) { this.stuBirth = stuBirth; } public String getStuTel() { return stuTel; } public void setStuTel(String stuTel) { this.stuTel = stuTel; } public String getStuEmial() { return stuEmial; } public void setStuEmial(String stuEmial) { this.stuEmial = stuEmial; } public String getDept() { return dept; } public void setDept(String dept) { this.dept = dept; } public String getStuIDCard() { return stuIDCard; } public void setStuIDCard(String stuIDCard) { this.stuIDCard = stuIDCard; } public String getClassName() { return className; } public void setClassName(String className) { this.className = className; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } /** * 获取学生的基本信息 * @return * @throws Exception */ //@Override public String getAllInfo() throws Exception { studentsInfo = studentService.getAllStudentInfo(); return SUCCESS; } } 然后就可以在JSP页面引入
<%@ taglib uri="/struts-tags" prefix="s" %>
然后获取数据了
<table class="table table-hover"> <tr> <th width="120">学号</th> <th width="120">姓名</th> <th width="120">性别</th> <th width="120">班级</th> <th width="120">系部</th> <th width="100">出生年月</th> <th width="100">操作</th> </tr> <s:iterator value="studentsInfo" id="ssif" > <tr> <td><s:property value="#ssif.stuID" /></td> <td><s:property value="#ssif.stuName" /></td> <td><s:property value="#ssif.stuSex" /></td> <td><s:property value="#ssif.className" /></td> <td><s:property value="#ssif.dept" /></td> <td><s:property value="#ssif.stuBirth" /></td> <td> <a class="button border-blue button-little" href="getStuInfoByIdAction?stuID=<s:property value='#ssif.stuID'/>">详情</a> <a class="button border-yellow button-little" href="getLearnScoresAction?stuID=<s:property value='#ssif.stuID' />" >学习</a> <a class="button border-green button-little" href="getMatchScoresAction?stuID=<s:property value='#ssif.stuID' />">比赛</a> </td> </tr> </s:iterator> </table>
实现数据获取
