完整的項目結構如左圖所示。所需jar包如左圖所示。
接下來開始搭建項目:
1、配置struts環境
1.1、導入struts2所需jia包
1.2、在web.xml中配置struts過濾器(web.xml文件)
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">
<!-- 配置Spring的監聽器,用於初始化ApplicationContext對象 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext*.xml</param-value>
</context-param>
<!-- 配置Struts2的主過濾器 -->
<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>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
1.3、導入struts.xml配置文件
<?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>
<!-- 配置爲開發模式 -->
<constant name="struts.devMode" value="true" />
<!-- 配置擴展名爲action -->
<constant name="struts.action.extension" value="action"/>
<package name="default" namespace="/" extends="struts-default">
</package>
</struts>
2、配置hibernate環境
2.1創建數據庫
2.2導入hibernate所需的jar包
2.3導入hibernate的配置文件
2.3.1hibernate.cfg.xml
<?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>
<!-- 配置數據庫方言 -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- 根據映射產生表結構的類型:
create-drop:木有表結構創建,下次啓動時刪除重新創建。適合學習階段
create:只做創建
update:探測表結構夠的變化,對於數據庫沒有的,進行更新操作。適合學習階段
validate:對比與數據庫的結構
-->
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 顯示sql語句及格式:開發調試階段非常有用 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<!-- 告知映射文件 -->
<mapping resource="com/lr/domain/Person.hbm.xml"/>
</session-factory>
</hibernate-configuration>
2.3.2 新建一個Person類,建立一個Person.hbm.xml
<?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.lr.domain">
<class name="Person">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
</class>
</hibernate-mapping>
3、配置spring環境
3.1 導入spring所需jar包
3.2 導入applicationContext.xml文件

- http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
- <!-- 自動掃描與裝配bean -->
- <context:component-scan base-package="com.lr"></context:component-scan>
-
- </beans>
4、接下來開始整合
4.1 spring與hibernate整合
spring來管理sessionFactory和事務
hibernate.cfg.xml
<?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>
<!-- 配置數據庫方言 -->
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- 根據映射產生表結構的類型:
create-drop:木有表結構創建,下次啓動時刪除重新創建。適合學習階段
create:只做創建
update:探測表結構夠的變化,對於數據庫沒有的,進行更新操作。適合學習階段
validate:對比與數據庫的結構
-->
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 顯示sql語句及格式:開發調試階段非常有用 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<!-- 告知映射文件 -->
<mapping resource="com/lr/domain/Person.hbm.xml"/>
</session-factory>
</hibernate-configuration>
applicationContext.xml
<?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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- 自動掃描與裝配bean -->
<context:component-scan base-package="com.lr"></context:component-scan>
<!-- 導入外部的properties文件 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 配置SessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<!-- 指定hibernate的配置文件位置 -->
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
<!-- 配置c3p0數據庫連接池 -->
<property name="dataSource">
<bean class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!-- 數據連接信息 -->
<property name="jdbcUrl" value="${jdbcUrl}"></property>
<property name="driverClass" value="${driverClass}"></property>
<property name="user" value="${user}"></property>
<property name="password" value="${password}"></property>
<!-- 其他配置 -->
<!--初始化時獲取三個連接,取值應在minPoolSize與maxPoolSize之間。Default: 3 -->
<property name="initialPoolSize" value="3"></property>
<!--連接池中保留的最小連接數。Default: 3 -->
<property name="minPoolSize" value="3"></property>
<!--連接池中保留的最大連接數。Default: 15 -->
<property name="maxPoolSize" value="5"></property>
<!--當連接池中的連接耗盡的時候c3p0一次同時獲取的連接數。Default: 3 -->
<property name="acquireIncrement" value="3"></property>
<!-- 控制數據源內加載的PreparedStatements數量。如果maxStatements與maxStatementsPerConnection均爲0,則緩存被關閉。Default: 0 -->
<property name="maxStatements" value="8"></property>
<!--maxStatementsPerConnection定義了連接池內單個連接所擁有的最大緩存statements數。Default: 0 -->
<property name="maxStatementsPerConnection" value="5"></property>
<!--最大空閒時間,1800秒內未使用則連接被丟棄。若爲0則永不丟棄。Default: 0 -->
<property name="maxIdleTime" value="1800"></property>
</bean>
</property>
</bean>
<bean id="testAction" class="com.lr.test.TestAction"
scope="prototype">
</bean>
<!-- 配置聲明式事務管理(採用註解的方式) -->
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<tx:annotation-driven transaction-manager="txManager"/>
</beans>
jdbc.properties
jdbcUrl = jdbc:mysql:///myssh
driverClass = com.mysql.jdbc.Driver
user = root
password = lirui
5、測試spring
springTest.java
測試sessionFactory
package com.lr.test;
import org.hibernate.SessionFactory;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class SpringTest {
private ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
//測試sessionFactory
@Test
public void testSessionFactory(){
SessionFactory sessionFactory = (SessionFactory) ac.getBean("sessionFactory");
System.out.println(sessionFactory);
}
}
使用junit測試,返回一個sessionFactory的地址。
Person.java
package com.lr.domain;
public class Person {
private Long id;
private String name;
public Person(){}
public Person(Long id, String name) {
this.id = id;
this.name = name;
}
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;
}
}
Person.hbm.xml
<?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.lr.domain">
<class name="Person">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
</class>
</hibernate-mapping>
測試事務
TestService.java
package com.lr.test;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.lr.domain.Person;
@Service("testService")
public class TestService {
@Resource
private SessionFactory sessionFactory;
@Transactional
public void saveTwoUser(){
Session currentSession = sessionFactory.getCurrentSession();
currentSession.save(new Person());
}
}
6、spring與sturts整合
整合之前:
TestAction.java
package com.lr.test;
import javax.annotation.Resource;
import com.opensymphony.xwork2.ActionSupport;
public class TestAction extends ActionSupport {
@Override
public String execute() throws Exception{
System.out.println("-------->testAction");
return "success";
}
}
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>
<!-- 配置爲開發模式 -->
<constant name="struts.devMode" value="true" />
<!-- 配置擴展名爲action -->
<constant name="struts.action.extension" value="action"/>
<package name="default" namespace="/" extends="struts-default">
<!-- 測試用的action,當與Spring整合後,class屬性寫的就是bean的名稱-->
<action name="test" class="com.lr.test.testAction">
<result name="success">/test.jsp</result>
</action>
</package>
</struts>
test.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
<h2>你好</h2>
</body>
</html>
導入struts2-spring-plugin-2.1.8.1.jar包,完成struts和spring的整合
testAction.java
package com.lr.test;
import javax.annotation.Resource;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import com.opensymphony.xwork2.ActionSupport;
@Controller
@Scope("prototype")
public class TestAction extends ActionSupport {
@Resource
private TestService testService;
@Override
public String execute() throws Exception{
System.out.println("-------->testAction");
testService.saveTwoUser();
return "success";
}
}
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>
<!-- 配置爲開發模式 -->
<constant name="struts.devMode" value="true" />
<!-- 配置擴展名爲action -->
<constant name="struts.action.extension" value="action"/>
<package name="default" namespace="/" extends="struts-default">
<!-- 測試用的action,當與Spring整合後,class屬性寫的就是bean的名稱-->
<action name="test" class="testAction">
<result name="success">/test.jsp</result>
</action>
</package>
</struts>
在瀏覽器上運行:http://localhost:8080/xbmuoa/test.action
完成ssh框架的整合。
