1. Struts2（struts-2.2.3.1）

1.1 加入struts2的jar包

     解压缩"struts2-blank"空项目，lib下的jar包全部拷贝。

1.2 web.xml加入struts2的过滤器

 <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>

1.3 添加struts.xml

     解压缩"struts2-blank"空项目，拷贝其中的struts.xml

     例子：

 

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

    "">

<struts> 

    <include file ="struts-default.xml" />

    <constant name="struts.enable.DynamicMethodInvocation" value="true" />

    <constant name="struts.devMode" value="true" />

   <constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />

    <package name="default" namespace="/" extends="struts-default">

        <default-action-ref name="index" />

        <global-results>

            <result name="error">/error.jsp</result>

        </global-results>

        <global-exception-mappings>

            <exception-mapping exception="java.lang.Exception" result="error"/>

        </global-exception-mappings>

        <action name="index">

            <result>/index.jsp</result>

        </action>

    </package>

 <package name="user" namespace="/user" extends="struts-default">

  <action name="userEdit_*" method="{1}" class="com.sample.action.UserEditAction">

            <result name="edit">/userEdit.jsp</result>

            <result name="list" type="redirect">/user/userList_init</result>

        </action>

        <action name="userList_*" method="{1}" class="com.sample.action.UserListAction">

            <result name="display">/userList.jsp</result>

        </action>

 </package>

</struts>

 

2. Hibernate（hibernate-3.3.2 hibernate-annotations-3.4.0）

 2.1 拷贝jar包（参照我的标题为的随笔）

 2.2 创建hibernate.cfg.xml文件

<?xml version='1.0' encoding='utf-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

        "">

<hibernate-configuration>

    <session-factory>

        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>

        <property name="connection.url">jdbc:mysql://localhost/spring</property>

        <property name="connection.username">root</property>

        <property name="connection.password">root</property>

        <property name="dialect">org.hibernate.dialect.MySQLDialect</property>

  <!-- Database connection settings

  <property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

        <property name="connection.url">jdbc:oracle:thin:@localhost:1521:invigilate</property>

        <property name="connection.username">invigilate</property>

        <property name="connection.password">invigilate</property>

        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>

        -->

        <!-- JDBC connection pool (use the built-in) -->

        <property name="connection.pool_size">1</property>

        <!-- Enable Hibernate's automatic session context management -->

        <property name="current_session_context_class">thread</property>

        <!-- Disable the second-level cache  -->

        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->

        <property name="show_sql">true</property>

        <!-- Echo all formatted SQL to stdout -->

        <property name="hibernate.format_sql">true</property>

        <!-- Drop and re-create the database schema on startup -->

        <property name="hbm2ddl.auto">update</property>

        <!--<mapping resource="com/sample/hibernate/model/Student.hbm.xml"/>

        <mapping class="com.sample.hibernate.model.Teacher"/>

        -->

        <mapping class="com.sample.model.User"/>

    </session-factory>

</hibernate-configuration>

 2.3 最好把日志配好（jar包在2.1的时候已经导入）

    log4j.properties：

log4j.rootLogger=debug,stdout,info,warn,error

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%5p %F:%L - %m%n

log4j.appender.stdout.encoding=UTF-8

 

log4j.logger.info=info

log4j.appender.info=org.apache.log4j.DailyRollingFileAppender

log4j.appender.info.layout=org.apache.log4j.PatternLayout

log4j.appender.info.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH:mm:ss}]  [ Class = %C | Method = %M | Line = %L ] | %m |%n  

log4j.appender.info.datePattern='.'yyyy-MM-dd

log4j.appender.info.Threshold=INFO

log4j.appender.info.append=true

log4j.appender.info.Encoding=UTF-8

log4j.appender.debug.datePattern='.'yyyy-MM-dd

log4j.appender.debug.Threshold=DEBUG

log4j.appender.debug.append=true

log4j.appender.debug.Encoding=UTF-8

log4j.appender.debug.File=debug.log

 

log4j.logger.warn=warn

log4j.appender.warn=org.apache.log4j.DailyRollingFileAppender

log4j.appender.warn.layout=org.apache.log4j.PatternLayout

log4j.appender.warn.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH:mm:ss}]  [ Class = %C | Method = %M | Line = %L ] | %m |%n  

log4j.appender.warn.datePattern='.'yyyy-MM-dd

log4j.appender.warn.Threshold=WARN

log4j.appender.warn.append=true

log4j.appender.warn.Encoding=UTF-8

log4j.appender.warn.File=warn.log

 

log4j.logger.error=error

log4j.appender.error=org.apache.log4j.DailyRollingFileAppender

log4j.appender.error.layout=org.apache.log4j.PatternLayout

log4j.appender.error.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH:mm:ss}]  [ Class = %C | Method = %M | Line = %L ] | %m |%n  

log4j.appender.error.datePattern='.'yyyy-MM-dd

log4j.appender.error.Threshold=ERROR

log4j.appender.error.append=true

log4j.appender.error.Encoding=UTF-8

log4j.appender.error.File=error.log

 

 2.4 到这里为止struts2, hibernate的构筑完了, 开始引入Spring

 3 导入Jar包

 3.1 spring-framework-3.0.5.RELEASE\dist目录下全部的Jar包

 3.2 aopalliance-1.0.jar，com.springsource.net.sf.cglib-2.2.0.jar

       com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar

　　 commons-dbcp-1.3.jar, commons-pool-1.5.6.jar, commons-logging-1.1.1.jar

4 添加修改配置文件

 4.1 修改web.xml文件，加入如下语句：

<context-param>

     <param-name>contextConfigLocation</param-name>

     <param-value>/WEB-INF/classes/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>

 </context-param>

<listener>

     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

 

4.2 修改struts.xml文件，加入如下语句：

<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />

 

4.3 添加applicationConext.xml

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns=""

 xmlns:xsi="" xmlns:aop=""

 xmlns:tx="" xmlns:context=""

 xsi:schemaLocation="

        

        

        

  

     

     

      ">

 <context:annotation-config />

 <context:component-scan base-package="com.sample" />

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

  destroy-method="close">

  <property name="driverClassName" value="${jdbc.driverClassName}" />

  <property name="url" value="${jdbc.url}" />

  <property name="username" value="${jdbc.username}" />

  <property name="password" value="${jdbc.password}" />

 </bean>

 <bean id="sessionFactory"

  class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

  <property name="dataSource" ref="dataSource" />

  <!-- xm方式 -->

  <!--

   <property name="mappingResources"> <list>

   <value>product.hbm.xml</value> </list> </property>

  -->

  <!-- annotated方式

 <property name="annotatedClasses">

   <list>

    <value>com.sample.model.User</value>

   </list>

  </property>

 -->

  <!-- 包读取方式 -->

  <property name="packagesToScan">

   <list>

    <value>com.sample.model</value>

   </list>

  </property>

  <property name="hibernateProperties">

   <props>

    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

    <prop key="hibernate.show_sql">true</prop>

   </props>

   <!--

    <value> hibernate.dialect=org.hibernate.dialect.MySQLDialect

    </value>

   -->

  </property>

 </bean>

<context:property-placeholder location="jdbc.properties" />

<!--

 <bean id="propertyConfigurer"

  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

  <property name="locations" value="jdbc.properties" />

 </bean>

-->

</beans>

 

4.4 修改Bean

类型上加注解：[@Component("userManager")]

成员变量的Set上面加注解：@Resource(name="userDao")

 

5 加入spring的事务管理（XML方式）

 5.1 在spring配置文件中加入HibernateTransactionManager

<bean id="transactionManager"

  class="org.springframework.orm.hibernate3.HibernateTransactionManager">

  <property name="sessionFactory" ref="sessionFactory" />

 </bean>

 

 5.2 在spring配置文件中加入advice

<tx:advice id="txAdvisor" transaction-manager="transactionManager">

  <tx:attributes>

   <tx:method name="get*" read-only="true" />

   <tx:method name="*" />

  </tx:attributes>

 </tx:advice>

 

 5.3 在spring配置文件中加入aopconfig

<aop:config>

  <aop:pointcut expression="execution(public * com.sample.service..*.*(..))"

   id="userServicePointcut" />

  <aop:advisor advice-ref="txAdvisor" pointcut-ref="userServicePointcut" />

</aop:config>

 

 6 DAO中使用HibernateTemplate

 6.1 spring配置文件中添加配置如下（加粗部分）

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns=""

 xmlns:xsi="" xmlns:aop=""

 xmlns:tx="" xmlns:context=""

 xsi:schemaLocation="

        

        

        

  

     

     

      ">

 <context:annotation-config /> 

 <context:component-scan base-package="com.procrate" />

 <!-- dataSource -->

 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

  destroy-method="close">

  <property name="driverClassName" value="${jdbc.driverClassName}" />

  <property name="url" value="${jdbc.url}" />

  <property name="username" value="${jdbc.username}" />

  <property name="password" value="${jdbc.password}" />

 </bean>

 <!-- sessionFactory -->

 <bean id="sessionFactory"

  class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">

  <property name="dataSource" ref="dataSource" />

  <property name="packagesToScan">

   <list>

    <value>com.procrate.model</value>

   </list>

  </property>

  <property name="hibernateProperties">

   <props>

    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>

    <prop key="hibernate.show_sql">true</prop>

   </props>

  </property>

 </bean>

 <!-- transactionManager -->

 <bean id="transactionManager"

  class="org.springframework.orm.hibernate3.HibernateTransactionManager">

  <property name="sessionFactory" ref="sessionFactory" />

 </bean>

 <!-- aop事务管理的XML配置 -->

 <aop:config>

  <aop:pointcut expression="execution(public * com.procrate.service..*.*(..))"

   id="userServicePointcut" />

  <aop:advisor advice-ref="txAdvisor" pointcut-ref="userServicePointcut" />

 </aop:config>

 <tx:advice id="txAdvisor" transaction-manager="transactionManager">

  <tx:attributes>

   <tx:method name="get*" read-only="true" />

   <tx:method name="*" />

  </tx:attributes>

 </tx:advice>

 

 <!-- HibernateTemplate -->

 <bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">

  <property name="sessionFactory" ref="sessionFactory"/>

 </bean>

 

 <context:property-placeholder location="classpath:jdbc.properties"/>

</beans>

 

 6.2 在DAO中注入HibernateTemplate，而不是用SessionFactory

 

7 添加Interceptor（登陆检查）

 

7.1 创建拦截器类，实现AbstractInterceptor抽象类，重写intercept方法，如下

package com.procrate.common.interceptor;

import java.util.Map;

import org.apache.log4j.Logger;

import com.opensymphony.xwork2.ActionInvocation;

import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

import com.procrate.action.UserLoginAction;

import com.procrate.common.constants.Constants;

import com.procrate.model.User;

public class AuthorityInterceptor extends AbstractInterceptor {

 

 private static final long serialVersionUID = 5553450256042738643L;

 private Logger log;

 

 @Override

 public String intercept(ActionInvocation actionInvocation) throws Exception {

  

  log = Logger.getLogger(this.getClass());

  log.debug("begin check login interceptor!");

        // 对LoginAction不做该项拦截

        Object action = actionInvocation.getAction();

        if (action instanceof UserLoginAction) {

            System.out.println("exit check login, because this is login action.");

            return actionInvocation.invoke();

        }

        // 确认Session中是否存在LOGIN

        Map<String, Object> session = actionInvocation.getInvocationContext().getSession();

        User user = (User) session.get(Constants.KEY_SESSION_USER);

        if (user != null) {

            // 存在的情况下进行后续操作。

            log.debug("already login!");

            return actionInvocation.invoke();

           

        } else {

            // 否则终止后续操作，返回LOGIN

            log.debug("no login, forward login page!");

            return Action.LOGIN;

        }

 }

}

 

7.2 配置struts.xml文件，这里有多种方法，一种可以定义一个包，把需要的拦截器加在里面，其他的包可以继承这个包（如下），还有一种就是把拦截器配置在需要的包里面（略）。

 <package name="struts-interceptor" extends="struts-default">

  <interceptors>

   <!-- 自定义拦截器，登陆检查 -->

   <interceptor name="authorityInterceptor" class="com.procrate.common.interceptor.AuthorityInterceptor"></interceptor>

   <!-- 拦截器栈 -->

   <interceptor-stack name="myInterceptor">

    <!-- Struts2（XWork）提供的拦截器   -->

    <!-- 输出Action执行的时间   -->

    <interceptor-ref name="timer" />

    <!-- 输出Action的名字   -->

    <interceptor-ref name="logger" />

    <!-- 引用自定义拦截器 -->

    <interceptor-ref name="authorityInterceptor" />

    <!-- 必须加-->

    <interceptor-ref name="defaultStack" />

   </interceptor-stack>

  </interceptors>

  <default-interceptor-ref name="myInterceptor" />

 </package>

 

 8 Ajax验证（dojo）

 8.1 添加包struts2-dojo-plugin-2.2.3.1.jar
