SSH(Spring+Struts2+Hibernate)框架搭建步骤(含配置文件以及运行结果)
1.創建web項目
2.導入ssh 所需要的多有jar包,到web-inf下面的lib里面
3.將導入過來的jar包都build--path一下
4.切換到myeclipse database視圖中,添加鏈接數據庫的鏈接
5.新建一個數據庫連接(如果忘記了數據庫鏈接時你可以去下面的網址中查看):
常用數據庫連接串與驅動總結
6.切換視圖,在src下面新建一個名為org.entity的包:
7.添加hibernate,右擊項目名,選擇myeclipseadd HIbernaete ……
在自動創建的hibernate.cfg.xml文件中,新加兩行代碼,實現打印輸出sql語句和格式化sql語句的功能。
<property name="show_sql">trueproperty> <property name="format_sql">trueproperty>8.右擊項目,添加struts
9.添加spring的內容:
10.web.xml里面的內容:
version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <listener><listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class> </listener><context-param><param-name>contextConfigLocationparam-name><param-value>classpath:applicationContext.xml</param-value> </context-param> <filter><filter-name>openSessionInViewFilterfilter-name><filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilterfilter-class> <init-param><param-name>flushModeparam-name><param-value>AUTOparam-value></init-param></filter> <filter-mapping><filter-name>openSessionInViewFilterfilter-name><url-pattern>/*url-pattern> </filter-mapping> <filter><filter-name>struts2filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping><filter-name>struts2filter-name><url-pattern>/*url-pattern> </filter-mapping><error-page> <error-code>404error-code> <location>/errorPage.jsplocation> </error-page> <welcome-file-list> <welcome-file>index.jspwelcome-file> </welcome-file-list> </web-app>
如果嫌復制麻煩,可以直接下載源文件(由于附件不支持.xml格式,所以下載完之后需要將后綴名改成.xml即可):
點擊可下載web.xml文件
11.配置spring的內容,打開applicationContext.xml文件:
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: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-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd "><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"> </property> </bean><bean id="txManage" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <tx:advice id="txAdvice" transaction-manager="txManage"> <tx:attributes><tx:method name="add*" propagation="REQUIRED"/><tx:method name="save*" propagation="REQUIRED"/><tx:method name="update*" propagation="REQUIRED"/><tx:method name="del*" propagation="REQUIRED"/><tx:method name="get*" read-only="true"/><tx:method name="find*" read-only="true"/> </tx:attributes> </tx:advice><aop:config> <aop:pointcut expression="execution(* org.service..*.*(..))" id="mycut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="mycut"/> </aop:config> </beans>
如果嫌復制麻煩,可以直接下載源文件(由于附件不支持.xml格式,所以下載完之后需要將后綴名改成.xml即可):
點擊下載applicationContext.xml文件
12.切換到myeclipse database視圖:(反向生成實體類)
13.右擊表:
點擊finish完成即可。
14.切換視圖至myeclipsep perspective
15.將項目發布到tomcat中。
16.啟動tomcat服務,檢查控制臺是否有錯誤(一般只要控制臺中沒有超鏈接錯誤,正常顯示毫秒數即可)。
17.如果沒有錯誤,將服務關掉。
18.開始根據實體類寫接口,一般一個實體類對應一個Dao接口
19.在IStudentDao接口中寫增刪改查的抽象方法。
20.開始寫Dao層的實現類,新建一個StudentDaoImpl的實現類。需要繼承HibernateDaoSupport類,實現IStudentDao接口。
實現類中的代碼:
publicclassStudentDaoImplextendsHibernateDaoSupportimplements IStudentDao {//添加 @Override publicvoidsaveStudent(Studentstudent) { this.getHibernateTemplate().save(student); } //修改 @Override publicvoidupdateStudent(Studentstudent) { this.getHibernateTemplate().update(student); } //刪除 @Override publicvoiddelStudent(Studentstudent) { this.getHibernateTemplate().delete(student); } //根據編號查詢 @Override publicStudentgetStudentById(intsid) { returnthis.getHibernateTemplate().get(Student.class, sid); } //查詢全部 @Override public List<Student> getStudentAll() { returnthis.getSession().createQuery("from Student").list(); }}21.創建Service接口,IStudentService:
IStudentService中的代碼:
22.創建Service的實現類,StudentServiceImpl。
在類中先創建dao層的對象,并且需要getters和setters
StudentServiceImpl中的代碼:
public class StudentServiceImpl implements IStudentService { //創建dao層的對象,需要getter和setter private IStudentDao studentDao; @Override public void saveStudent(Student student) { studentDao.saveStudent(student); }@Override public void updateStudent(Student student) { studentDao.updateStudent(student); }@Override public void delStudent(Student student) { studentDao.delStudent(student); }@Override public Student getStudentById(int sid) { return studentDao.getStudentById(sid); }@Override public ListgetStudentAll() { return studentDao.getStudentAll(); }/** * @author Mu Xiongxiong * @created 2020-4-30 下午2:47:37 * @return type * 個人博客:https://blog.csdn.net/qq_34137397 */ public IStudentDao getStudentDao() { return studentDao; }/** * @author Mu Xiongxiong * @created 2020-4-30 下午2:47:37 * @param studentDao * 個人博客:https://blog.csdn.net/qq_34137397 */ public void setStudentDao(IStudentDao studentDao) { this.studentDao = studentDao; }}23.創建applicationContext-dao.xml文件(可以復制一份applicationContext.xml一份,對應的再改一下),代碼如下:
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: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-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd "><bean id="studentDao" class="org.dao.impl.StudentDaoImpl"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> </beans>
24.創建applicationContext-service.xml文件(可以復制一份applicationContext-dao.xml一份,對應的再改一下),代碼如下:
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: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-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd "><bean id="studentService" class="org.service.impl.StudentServiceImpl"> <property name="studentDao" ref="studentDao"></property> </bean> </beans>
25.創建StudentAction類,繼承ActionSupport.
StudentAction里面的代碼,省略展示getters和setters的方法:
26.配置Struts.xml文件:
version="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> <package?name="default"?extends="struts-default"> <action name="StudentAll" class="org.web.StudentAction" method="StudentAll"> <result name="success">index.jsp</result> </action> </package> </struts>
27.index.jsp頁面,需要將學生信息用table的形式展示出來
首先在最上面添加jstl的標簽庫:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>寫一個table表格遍歷信息:
<table border="1"><tr><td>學號</td><td>姓名</td><td>密碼</td><td>電話</td><td>年級</td><td>操作</td></tr> <c:forEach items="${studentList }" var="stu"><tr><td>${stu.sid }</td><td>${stu.sname}</td><td>${stu.spass }</td><td>${stu.sphone }</td><td>${stu.grade.gname }</td><td><a href="getStudentByid?sid=${stu.sid }">修改a>|<a href="delStudent?sid=${stu.sid }">刪除a></td></tr> </c:forEach> </table> ?28. 創建applicationContext-action.xml文件(可以復制一份applicationContext-dao.xml一份,對應的再改一下),代碼如下:
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: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-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd "><bean id="studentAction" class="org.web.StudentAction"> <property?name="studentService"?ref="studentService"></property> </bean> </beans>
29.在applicationContext.xml中引入applicationContext-dao.xml, applicationContext-service.xml, applicationContext-action.xml文件,引入方式:
運行結果:
