maven搭建 SSH

             上次讲述了maven搭建springmvc+mybatis框架，若未浏览却对此感兴趣的话，请移步这里：maven搭建 springmvc+mybatis应用。

             本次主要讲解使用maven搭建struts2+spring+hibernate框架。用的struts的版本是2.3.8，spring的版本是3.0.5（由于本人引用的依赖是struts2-spring-plugin，它本身依赖与spring3.0.5以及struts2.3.8，故本人使用了默认依赖，当然如果你想换spring版本的话可以使用maven的exclusion属性去掉spring的依赖，然后再加入你自己想使用的spring版本依赖。但本人不敢保证struts2-spring-plugin与你想使用的spring版本兼容，你可以自己试一下，若可以兼容@我一下，大家共同进步，谢谢），c3p0用的是0.9.1.2，下面开始项目搭建

            首先还是先创建一个maven项目，并且编辑pom将要引用的jar包依赖引入。编辑后的pom文件如下

<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/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.qijian</groupId><artifactId>SSH</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>SSH Maven Webapp</name><url>http://maven.apache.org</url><!-- 构件的版本 --><properties><junit.version>3.8.1</junit.version><logback.version>1.1.2</logback.version><struts.version>2.3.8</struts.version><spring.version>3.0.5.RELEASE</spring.version><hibernate.annotations.version>3.5.6-Final</hibernate.annotations.version><aspectj.version>1.8.1</aspectj.version><c3p0.version>0.9.1.2</c3p0.version><mysql.version>5.1.31</mysql.version></properties><dependencies><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>${junit.version}</version><scope>test</scope></dependency><dependency><groupId>ch.qos.logback</groupId><artifactId>logback-classic</artifactId><version>${logback.version}</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-spring-plugin</artifactId><version>${struts.version}</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-json-plugin</artifactId><version>${struts.version}</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-convention-plugin</artifactId><version>${struts.version}</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId><version>${aspectj.version}</version></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjrt</artifactId><version>${aspectj.version}</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-orm</artifactId><version>${spring.version}</version></dependency><!-- 用c3p0连接池去管理数据库连接 --><dependency><groupId>c3p0</groupId><artifactId>c3p0</artifactId><version>${c3p0.version}</version></dependency><dependency><groupId>org.hibernate</groupId><artifactId>hibernate-annotations</artifactId><version>${hibernate.annotations.version}</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency></dependencies><build><finalName>SSH</finalName></build></project>

 

      然后就是配置SSH了，首先编辑web.xml，配置struts2的过滤器

   

<filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class><init-param><param-name>struts.devMode</param-name><param-value>true</param-value></init-param><init-param><param-name>actionPackages</param-name><param-value>com.qijian.action</param-value></init-param></filter><filter-mapping><filter-name>struts2</filter-name><url-pattern>/*</url-pattern></filter-mapping>

          其中struts.devMode参数是将struts2的模式调为开发模式以便于调试（其实就是将错误信息打印到页面）；参数actionPackages是指定你的controller的物理位置，注意在你创建controller的时候，其所在的包路径不能有用"controller"以单个词语的形式出现（例如：con.qijian.controller，这个就不行），否则的话会导致请求无法处理，会和struts2起冲突（具体冲突原因不明，未来得及看struts2的源代码）。其整个web.xml文件的源代码如下：

<?xml version="1.0" encoding="UTF-8"?><web-app 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"version="3.0" metadata-complete="true"><display-name>SSH</display-name><context-param><param-name>contextConfigLocation</param-name><param-value>classpath*:spring*.xml</param-value></context-param><filter><filter-name>characterEncodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param><init-param><param-name>forceEncoding</param-name><param-value>true</param-value></init-param></filter><filter-mapping><filter-name>characterEncodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><filter><filter-name>struts2</filter-name><filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class><init-param><param-name>struts.devMode</param-name><param-value>true</param-value></init-param><init-param><param-name>actionPackages</param-name><param-value>com.dou.action</param-value></init-param></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><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

    参数contextConfigLocation是指定了spring配置文件的位置，跟“maven搭建 springmvc+mybatis应用”一致，本人也将所有配置文件放在了src/main/resources目下,org.springframework.web.context.ContextLoaderListener是在启动web容器时装配spring配置信息。

         下面是spring的配置，主要就是启动了注解，其代码如下

<?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:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc"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-3.0.xsd       http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.0.xsd       http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd       http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd           http://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">      <!--扫描项目目录启用注解-->       <context:component-scan base-package="com.qijian"/></beans>

 

         然后是hibernate的配置，主要是引入属性文件，配置数据源，配置事物管理，其代码如下：

  

<?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:p="http://www.springframework.org/schema/p"xmlns:mvc="http://www.springframework.org/schema/mvc" 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-3.0.xsd       http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.0.xsd       http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx-3.0.xsd       http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd           http://www.springframework.org/schema/aop       http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"><!-- 引入数据库属性文件 --><context:property-placeholder location="classpath*:config.properties" /><!--c3p0数据库连接池 --><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"destroy-method="close"><property name="driverClass" value="${driverClassName}" /><property name="jdbcUrl" value="${jdbc_url}" /><property name="user" value="${jdbc_username}" /><property name="password" value="${jdbc_password}" /><property name="initialPoolSize" value="1" /><property name="minPoolSize" value="0" /><property name="maxPoolSize" value="50" /><property name="acquireIncrement" value="5" /><property name="maxIdleTime" value="10" /><property name="maxStatements" value="0" /></bean><bean id="sessionFactory"class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hiberante.format_sql">true</prop><!-- 延迟加载 --><prop key="hibernate.cglib.use_reflection_optimizer">true</prop><!--是否允许Hibernate用JDBC的可滚动的结果集,对分页时的设置非常有帮助 --><prop key="hibernate.jdbc.use_scrollable_resultset">false</prop></props></property><property name="dataSource"><ref bean="dataSource" /></property><property name="packagesToScan"><list><value>com.dou.dao.po</value></list></property><!-- 设置数据源是否使用事务包装 --><property name="useTransactionAwareDataSource"><value>true</value></property></bean><!-- hibernate事物开始 --><bean id="hibernateTransactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory"><ref local="sessionFactory" /></property></bean><!-- 注解式事物 --><!-- <tx:annotation-driven transaction-manager="hibernateTransactionManager"/> --><!--声明性事物 --><tx:advice id="txAdvice" transaction-manager="hibernateTransactionManager"><tx:attributes><tx:method name="store*" propagation="REQUIRED" /><tx:method name="add*" propagation="REQUIRED" /><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /></tx:attributes></tx:advice><aop:config><aop:pointcut id="allServiceMethod"expression="execution(* com.qijian.service.impl.*.*(..))" /><aop:advisor pointcut-ref="allServiceMethod" advice-ref="txAdvice" /></aop:config><!-- hibernate事物结束 --></beans>

 

     这里的事物用的是spring为hibernate提供的HibernateTransactionManager，当然你也可以用spring 的DataSourceTransactionManager管理事物，详情请看“maven搭建 springmvc+mybatis应用”一文。

    最后还有一个数据库连接信息的properties文件，主要是连接数据库的用户名密码等，代码如下：

     

driverClassName=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://127.0.0.1:3306/mybatis?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=rootjdbc_password=king

 

    到此基本配置就差不多了，然后就可以编写代码跑程序了，祝大家一切顺利
