SSH2搭建步骤 struts-2.2.3.1 hibernate-3.3.2 hibernate-annotations-3.4.0 spring-3.0.5

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"
"http://struts.apache.org/dtds/struts-2.0.dtd">

    <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SSH2 JAR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"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

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

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

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

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

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

<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.info.File=info.log

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

4.3 添加applicationConext.xml

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

</bean>

<bean id="sessionFactory"
  class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
  <property name="dataSource" ref="dataSource" />
  
  
  <!-- annotated方式

<property name="annotatedClasses">
   <list>
    <value>com.sample.model.User</value>
   </list>
  </property>

-->
  
<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>
   
  </property>
</bean>

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

</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

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）

<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" />
  <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>

<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<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>


<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）。

8 Ajax验证（dojo）

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