在網上經常看到用Eclipse整合SSH然后我就在學校用JB整合了一個SSH的例子演示出來，很有成就感! 呵呵
打開JB建一個工程然后〉建站點〉建AcionForm , Acion , JSP這樣就把Struts框架搭建出來了！
然后就是把Hibernate的Jar 和Spring 的Jar 導進工程當中建好的Struts框架如圖:
然后開始編寫一個接口UserDAO.java
package SpringPack;
public interface UserDAO {
? public abstract boolean isValidUser(String name,String password);
}
編寫一個類繼承該接口UserDAOImp.java
package SpringPack;
import org.springframework.orm.hibernate.support.*;
import net.sf.hibernate.SessionFactory;
import java.util.List;
import Hibernate.hibernateTest;
import net.sf.hibernate.*;
public class UserDAOImp extends HibernateDaoSupport implements UserDAO{
? public boolean isValidUser(String name,String pwd){
??? hibernateTest t = null;
??? try {
????? t = new hibernateTest();
??? }
??? catch (HibernateException ex) {
????? ex.printStackTrace();
??? }
??? if(t.checkUser(name,pwd)) return true;
??? return false;
? }
}
然后編寫一個Bean用來映射數據表的字段
package Hibernate;
public class user {
? private String username;
? private String password;
? public user() {
? }
? public void setUsername(String username) {
??? this.username = username;
? }
? public void setPassword(String password) {
??? this.password = password;
? }
? public String getUsername() {
??? return username;
? }
? public String getPassword() {
??? return password;
? }
}
編寫hibernate.cfg.xml文件用于連接數據庫的配置文件：
<?xml version='1.0' encoding='big5'?>
<!DOCTYPE hibernate-configuration
??? PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
??? "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd
">
<hibernate-configuration>
??? <session-factory>
??????? <property name="show_sql">true</property>
??????? <property name="dialect">net.sf.hibernate.dialect.MySQLDialect</property>
??????? <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
??????? <property name="connection.url">jdbc:mysql://localhost/myDB</property>
??????? <property name="connection.username">root</property>
??????? <property name="connection.password">test</property>
??????? <mapping resource="user.hbm.xml"/>
??? </session-factory>
</hibernate-configuration>
然后下面編寫一個描述數據庫映射表字段信息的mapping文件User.hbm.xml
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
??? PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN"
??? "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd
">
<hibernate-mapping>
??? <class name="Hibernate.user" table="user">
??????? <id name="username" type="string" unsaved-value="null">
??????????? <column name="username" sql-type="varchar(20)" />
??????????? <generator class="uuid.hex"/>
??????? </id>
??????? <property name="password" type="string" column="password"/>
??? </class>
</hibernate-mapping>
好了現在Hibernate已基本搭建出來了，下一步我們要用Spring來整合Hibernate 和Struts 操作步驟很簡單編寫一個applicationContext.xml文件放在站點的根目錄即可:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd
">
<beans>
? <bean name="/loginAction"
??? class="StrutsPack.LoginAction"
??? singleton="false">
? </bean>
</beans>
要整合Struts還要在Struts-config.xml文件中做一些修改如下:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd
">
<struts-config>
? <form-beans>
??? <form-bean name="loginActionForm" type="StrutsPack.LoginActionForm" />
? </form-beans>
? <action-mappings>
??? <action? name="loginActionForm" path="/loginAction" scope="session" type="org.springframework.web.struts.DelegatingActionProxy" validate="false">
????? <forward name="Success" path="/success.jsp" />
????? <forward name="Failure" path="/Failure.jsp" />
??? </action>
? </action-mappings>
? <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
??? <set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
? </plug-in>
</struts-config>
好了現在還要編寫一個Hibernate的輔助文件如下:
package Hibernate;
import net.sf.hibernate.*;
import net.sf.hibernate.cfg.*;
import java.util.List;
import java.util.ListIterator;
public class hibernateTest {
? Session session;
? public hibernateTest()
? throws HibernateException{
??? SessionFactory factory=new Configuration().configure().buildSessionFactory();
???? session=factory.openSession();
? }
? public boolean checkUser(String name,String pwd){
? List count = null;
? try {
??? Query q = session.createQuery(
??????? "select count(*) from user where username=? and password=?");
??? q.setString(1, name);
??? q.setString(2, pwd);
??? count = q.list();
? }
? catch (HibernateException ex) {
??? ex.printStackTrace();
? }
? ListIterator list=count.listIterator();
? Integer s=(Integer)list.next();
? if(s.intValue() > 0 ) return true;
? return false;
? }
}
然后就可以在LoginAction.java中調用了LoginAction.java文件如下:
package StrutsPack;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForm;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.Action;
import SpringPack.*;
public class LoginAction
??? extends Action {
? private static final String SUCCESS="Success";
? private static final String FAILURE="Failure";
? private UserDAO userdao=new UserDAOImp();
? public ActionForward execute(ActionMapping mapping,
?????????????????????????????? ActionForm actionForm,
?????????????????????????????? HttpServletRequest servletRequest,
?????????????????????????????? HttpServletResponse servletResponse) {
??? LoginActionForm loginform = (LoginActionForm) actionForm;
??? if(userdao.isValidUser(loginform.getUsername(),loginform.getPassword())){
??? return mapping.findForward(SUCCESS);
??? }
??? return mapping.findForward(FAILURE);
? }
? public UserDAO getUserDAO() {
??? return userdao;
}
public void setUserDAO(UserDAO userDAO) {
? this.userdao = userDAO;
}
}
至此JB開發一個簡單的SSH就結束了感覺就是兩個字麻煩！還是使用Eclispe開發方便!下面是具體的path:
