1 下载包
hibernate: http://hibernate.org/orm/downloads/
struts2： http://struts.apache.org/download.cgi
spring4： http://maven.springframework.org/release/org/springframework/spring/4.0.2.RELEASE/
2 新建空Web Project
3 复制struts2常用包到WebRoot/WEB-INF/lib下
4 修改web.xml
<?xml 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"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <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>
</web-app>
在WEB-INF下新建jsp文件夹，用来保存jsp文件，也可以直接放在WebRoot下。放在WEB-INF下的好处是只有服务端可以访问。
/jsp/Login.jsp：
<%@ page contentType="text/html; charset=UTF-8" %> <%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <title>Login</title> </head> <body> <s:form action="Auth" method="POST"> <s:textfield key="name"/> <s:password key="pwd" /> <s:submit/> </s:form> </body> </html>
/jsp/Welcome.jsp
<%@ page contentType="text/html; charset=UTF-8" %> <%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <title>Welcome</title> </head> <body> <h2>Welcome!</h2> name: ${name} <br /> pwd: ${pwd} </body> </html>
5 在src目录下新建struts.xml文件
struts.xml
<?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"> <struts> <package name="default" namespace="/" extends="struts-default"> <action name="Login" class="com.test.struts2.DemoAction" method="login"> <result>/WEB-INF/jsp/Login.jsp</result> </action> <action name="Auth" class="com.test.struts2.DemoAction" method="auth"> <result>/WEB-INF/jsp/Welcome.jsp</result> </action> </package> </struts>
在src下新建DemoAction.java
package com.test.struts2;
import com.opensymphony.xwork2.ActionSupport;
public class DemoAction extends ActionSupport {
private String name;
private String pwd;
public String execute() {
return SUCCESS;
}
public String login() {
return SUCCESS;
}
public String auth() {
return SUCCESS;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
现在的工程结构图：
struts就搭好了。访问http://localhost:8081/demo/Login查看结果。
暂时没有做登录验证。只是显示输入的用户名和密码。
4 复制hibernate常用包到/WebRoot/WEB-INF/lib下
先把lib/required下面的包复制到lib中，然后下载mysql-connector-java-5.1.7-bin.jar 这个包加入。可能会下载到不同的版本，都无所谓。
新建Account类：
package com.test.model; public class Account { private Long id; private String name; private String pwd; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } }
新建Account类和数据库表的映射文件Account.hbm.xml：
<?xml version="1.0"?> <!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.test.model"> <class name="Account" table="Account"> <id name="id" column="Account_ID"> <generator class="increment"/> </id> <property name="name" column="name"/> <property name="pwd" column="pwd"/> </class> </hibernate-mapping>
在本地MySQL或者其他数据库新建数据库demo。新建hibernate配置文件：
<?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"> <hibernate-configuration> <session-factory> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/demo</property> <property name="connection.username">root</property> <property name="connection.password">root</property> <property name="connection.pool_size">5</property> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="show_sql">true</property> <property name="hbm2ddl.auto">create</property> <property name="current_session_context_class">thread</property> <mapping resource="com/test/model/Account.hbm.xml"/> </session-factory> </hibernate-configuration>
根据自己的实际情况填写。现在只要本地可以连接数据库就OK了。新建IDao接口：
package com.test.dao.impl; import java.util.List; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; import com.test.dao.IDao; public class IDaoImpl<T> implements IDao<T> { private static final SessionFactory sessionFactory; static { try { sessionFactory = new Configuration() .configure().buildSessionFactory(); } catch (Throwable ex) { throw new ExceptionInInitializerError(ex); } } @Override public T get(String hql) { Session session = sessionFactory.openSession(); try { session.beginTransaction(); List list = session.createQuery(hql).list(); if (list != null && list.size() > 0) return (T) list.get(0); return null; } finally { session.getTransaction().commit(); session.close(); } } }
现在Hibernate已经和struts整合完成。实现了用户登录数据库验证。
5 搭建Spring环境
导入libs/下的*RELEASE.jar文件就可以了。下载commons-dbcp-1.4.jar，commons-pool-1.6.jar包。这两个包跟数据连接池有关。
为了实现Service层和dao层的分离，新建Service层。
Iservice.java:
package com.test.service; public interface IService<T> { public T get(String hql); }
IServiceImpl.java
package com.test.service.impl; import com.test.dao.IDao; import com.test.service.IService; public class IServiceImpl<T> implements IService<T> { private IDao<T> dao; public IDao<T> getDao() { return dao; } public void setDao(IDao<T> dao) { this.dao = dao; } @Override public T get(String hql) { // TODO Auto-generated method stub return dao.get(hql); } }
为了使用spring，新建applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <?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:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <!-- 数据源配置 --> <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/demo" /> <property name="username" value="root" /> <property name="password" value="root" /> <property name="initialSize" value="5" /> <property name="maxActive" value="500" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" destroy-method="destroy"> <property name="dataSource" ref="dataSource" /> <property name="mappingResources"> <list> <value>com/test/model/Account.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> </props> </property> </bean> <bean id="dao" class="com.test.dao.impl.IDaoImpl"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 在Service层配置事务 --> <bean id="hibernateTransactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> <!-- <property name="dataSource" ref="dataSource" /> --> </bean> <bean id="hibernateTransactionAttributeSource" class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource"> <property name="properties"> <props> <prop key="*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> <bean id="service" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <property name="transactionManager" ref="hibernateTransactionManager" /> <property name="target"> <bean class="com.test.service.impl.IServiceImpl"> <property name="dao" ref="dao" /> </bean> </property> <property name="transactionAttributeSource" ref="hibernateTransactionAttributeSource" /> </bean> <!-- spring生成action --> <bean id="demoAction" scope="prototype" class="com.test.struts2.DemoAction"> <property name="service" ref="service" /> </bean> </beans>
现在Hibernate.cfg.xml已经没用了，删掉这个文件。为了struts和spring结合，加入struts2-spring-plugin-2.3.16.jar包。
web.xml
<?xml 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"> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- spring配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/classes/applicationContext.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <!-- struts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> </web-app>
struts.xml
<?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"> <struts> <constant name="struts.devMode" value="true" /> <constant name="struts.objectFactory" value="spring" /> <package name="default" namespace="/" extends="struts-default"> <action name="Login" class="com.test.struts2.DemoAction" method="login"> <result>/WEB-INF/jsp/Login.jsp</result> </action> <action name="Auth" class="com.test.struts2.DemoAction" method="auth"> <result>/WEB-INF/jsp/Welcome.jsp</result> <result name="error">/WEB-INF/jsp/error.jsp</result> </action> </package> </struts>
DemoAction.java
package com.test.struts2; import com.opensymphony.xwork2.ActionSupport; import com.test.model.Account; import com.test.service.IService; public class DemoAction extends ActionSupport { private IService service; private String name; private String pwd; public String execute() { return SUCCESS; } public String login() { return SUCCESS; } public String auth() { String hql = "from Account where name='" + name + "' and pwd='" + pwd + "'"; Account account = (Account) service.get(hql); return account == null ? "error" : SUCCESS; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } public IService getService() { return service; } public void setService(IService service) { this.service = service; } }
现在ssh整合基本上完成了。还有一些没有描述的包可以在源码里面查看。
