利用maven实现struts2+hibernate3+spring3详解

最近在试着接触maven，感觉用maven来部署项目比以前方便了许多；

废话不多说，现在就开始maven搭建struts2+hibernate3+spring3的框架吧；

我的项目中用的是eclipse，下面是项目的结构图

1、编写pom.xml添加项目需要的依赖

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.clf</groupId><artifactId>div</artifactId><version>0.0.1-SNAPSHOT</version><dependencies><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-core</artifactId><version>2.3.12</version></dependency><dependency><groupId>jstl</groupId><artifactId>jstl</artifactId><version>1.2</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>3.2.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>3.2.2.RELEASE</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-core</artifactId><version>3.6.4.Final</version></dependency><dependency><groupId>commons-lang</groupId><artifactId>commons-lang</artifactId><version>2.6</version><type>jar</type><scope>compile</scope></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>3.2.2.RELEASE</version></dependency><dependency><groupId>commons-dbcp</groupId><artifactId>commons-dbcp</artifactId><version>1.4</version></dependency><dependency><groupId>commons-pool</groupId><artifactId>commons-pool</artifactId><version>1.6</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.24</version></dependency><dependency><groupId>com.googlecode.sli4j</groupId><artifactId>sli4j-slf4j</artifactId><version>2.0</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>3.2.2.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>3.2.2.RELEASE</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-spring-plugin</artifactId><version>2.3.12</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-convention-plugin</artifactId><version>2.3.12</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency></dependencies></project>

2、接着我们web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"id="WebApp_ID" version="2.5"><display-name>div</display-name><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><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><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener></web-app>

3、strut.xml配置

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.1.7//EN""http://struts.apache.org/dtds/struts-2.1.7.dtd"><struts><constant name="struts.devMode" value="true" /><constant name="struts.i18n.encoding" value="utf-8" /><constant name="struts.convention.result.path" value="/WEB-INF/pages/" /></struts>

4、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: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-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/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"><context:annotation-config /><context:component-scan base-package="com.clf.dao" /><context:component-scan base-package="com.clf.service" /><context:property-placeholder location="classpath:jdbc.properties" /><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="${driverClassName}"></property><property name="url" value="${url}"></property><property name="username" value="${username}"></property><property name="password" value="${password}"></property></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="packagesToScan"><list><value>com.clf.entity</value></list></property><property name="hibernateProperties"><value>hibernate.dialect=org.hibernate.dialect.MySQL5Dialecthibernate.hbm2ddl.auto=updatehibernate.show_sql=truehibernate.format_sql=true</value></property></bean><bean id="txManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory" /></bean><tx:annotation-driven transaction-manager="txManager" /></beans>

5、jdbc.properties配置

driverClassName=org.gjt.mm.mysql.Driverurl=jdbc:mysql://localhost:3306/divusername=rootpassword=123456

6、log4j.properties

log4j.rootLogger=WARN,stdoutlog4j.appender.stdout=org.apache.log4j.ConsoleAppenderlog4j.appender.stdout.layout=org.apache.log4j.PatternLayoutlog4j.appender.stdout.layout.ConversionPattern=%d%p[%c]-%m%n

7、mysql数据库脚本：

SET FOREIGN_KEY_CHECKS=0;-- ------------------------------ Table structure for `user`-- ----------------------------DROP TABLE IF EXISTS `user`;CREATE TABLE `user` (  `id` bigint(20) NOT NULL AUTO_INCREMENT,  `USERNAME` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,  `PASSWORD` varchar(255) COLLATE utf8_unicode_ci DEFAULT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;-- ------------------------------ Records of user-- ----------------------------INSERT INTO `user` VALUES ('1', 'clf', 'clf');

这里做一下解释，由于自己研究的，就没有严格的用面向接口来设计项目。
