SSH开发环境整合搭建

1.建立动态web工程，加入必要的jar包。

antlr-2.7.7.jar
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
c3p0-0.9.1.2.jar
com.springsource.net.sf.cglib-2.2.0.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang3-3.1.jar
commons-logging-1.1.1.jar
dom4j-1.6.1.jar
freemarker-2.3.19.jar
hibernate-commons-annotations-4.0.2.Final.jar
hibernate-core-4.2.4.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
javassist-3.11.0.GA.jar
javassist-3.15.0-GA.jar
jboss-logging-3.1.0.GA.jar
jboss-transaction-api_1.1_spec-1.0.1.Final.jar
mchange-commons-java-0.2.10.jar
mysql-connector-java-5.1.26-bin.jar
ognl-3.0.5.jar
spring-aop-4.0.0.RELEASE.jar
spring-aspects-4.0.0.RELEASE.jar
spring-beans-4.0.0.RELEASE.jar
spring-context-4.0.0.RELEASE.jar
spring-core-4.0.0.RELEASE.jar
spring-expression-4.0.0.RELEASE.jar
spring-jdbc-4.0.0.RELEASE.jar
spring-orm-4.0.0.RELEASE.jar
spring-tx-4.0.0.RELEASE.jar
spring-web-4.0.0.RELEASE.jar //此包为spring整合到web的关键jar包
struts2-core-2.3.4.jar
struts2-spring-plugin-2.3.4.jar
xwork-core-2.3.4.jar

2. web.xml的配置

<!-- 配置spring监听器，在动态web加载时就将其配置文件一同加载 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <!-- 将spring配置文件放入一个IOC容器 -->
        <param-value>classpath:applicationcontext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    
<!-- struts2的配置文件，拦截所有请求，判断是否是struts2请求，若是则拦截，若不是则放行 -->
    <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>

3. spring整合hibernate及struts2的配置文件

　　图解如下：

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"
    xmlns:aop="http://www.springframework.org/schema/aop"
    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-4.0.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">
    <!-- 加载db.properties文件 -->
    <context:property-placeholder location="classpath:db.properties"/>
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="user" value="${user}"></property>
        <property name="password" value="${password}"></property>
        <property name="driverClass" value="${driver}"></property>
        <property name="jdbcUrl" value="${url}"></property>
        <property name="initialPoolSize" value="${initialPoolSize}"></property>
        <property name="maxPoolSize" value="${maxPoolSize}"></property>
    </bean>
    <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
        <property name="mappingLocations" value="classpath:com/ssh/entity/*.hbm.xml"></property>
    </bean>　　　 
　　 <bean id="employeeAction" class="com.ssh.action.EmployeeAction" scope="prototype">
　　　　 <property name="employeeService" ref="employeeService"></property>
　　　 　<property name="departmentService" ref="departmentService"></property>
    </bean>
</beans>

db.properties 数据库连接的信息

user=root
password=123
driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///ssh
initialPoolSize=5
maxPoolSize=10

hibernate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
        <property name="show_sql">true</property>
        <property name="hibernate.format_sql">true</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
    </session-factory>
</hibernate-configuration>

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.action.extension" value="action,do,"/>
    <package name="hello" namespace="/" extends="struts-default">        
        <action name="emp-*" class="employeeAction" method="{1}"> <!-- class中用的并不是全类名，是在spring中管理该类的id -->
            <result name="save" type="redirectAction">/emp-list</result>
        </action>
    </package>
</struts>

这样基本的开发环境就搭建好了
