1、导入jar包
可以在src下添加一个log4j.properties文件来记录日志
2、加入实体类+映射文件
映射：从类入手class+属性
a、映射的头文件在：hibernate3.jar-->org.hibernate-->hibernate-mapping-3.0.dtd
b、type=“java.lang.String"根据属性来更改+column（加长度的时候要独立出来）
注意：如果有遇到entity not found 就要想到路径错误，映射文件中有那个package=”包名“还有就是在hibernate.cfg.xml的mappling那路径有没有正确
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="po">
<class name="CheckResult" table="biz_check_result">

</column>
</many-to-one>
<property name="result" type="string">
<column name="result" length="20" not-null="true">
<comment>审核结果</comment>
</column>
</property>
<property name="comment" type="string">
<column name="comment">
<comment>审核意见</comment>
</column>
</property>
</class>
</hibernate-mapping>
映射文件
hibernate.cfg.xml文件。头文件在：hibernate3.jar-->org.hibernate-->hibernate-configuration-3.0.dtd
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.url">
jdbc:oracle:thin:@localhost:1521:jbit
</property>
<property name="connection.username">rong</property>
<property name="connection.password">rong</property>
<property name="connection.driver_class">
oracle.jdbc.driver.OracleDriver
</property>
<property name="dialect">
org.hibernate.dialect.OracleDialect
</property>
<property name="show_sql">true</property>
<property name="format_sql">true</property> <mapping resource="po/Employee.hbm.xml" />
<mapping resource="po/Position.hbm.xml" />
</session-factory> </hibernate-configuration>
用spring的把hibernate.cfg.xml整合到applicationContext.xml文件中
先配置dataSource找BasicDataSource
然后在注入sessionFactory
applicationContext.xml文件刚开始写入下面的代码
<!-- dataSource -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="url" value="jdbc:oracle:thin:@localhost:1521:jbit"></property>
<property name="username" value="rong"></property>
<property name="password" value="rong"></property>
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>
<!-- 最大连接数是100 -->
<property name="maxActive" value="100"></property>
<!-- 最大空闲数是10 -->
<property name="maxIdle" value="10"></property>
<!-- 最大等待时间毫秒为单位 -->
<property name="maxWait" value="10000"></property>
</bean>
<!-- SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<!-- hibernateProperties 辅助参数 -->
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.dialecg">org.hibernate.dialect.Oracle10gDialect</prop>
</props>
</property>
<!-- 文件太多的话，不适合用 -->
<!-- <property name="mappingResources">
<list>
<value>cn/bdqn/jboa/entity/Department.hbm.xml</value>
<value>cn/bdqn/jboa/entity/Dictionary.hbm.xml</value>
<!-- <value>cn/bdqn/jboa/entity/Employee.hbm.xml</value> -->
<value>cn/bdqn/jboa/entity/Position.hbm.xml</value>
</list>
</property> -->
<!-- 指定的包的路径 、找包下所有的映射文件-->
<property name="mappingDirectoryLocations">
<list>
<value>classpath:cn/bdqn/jboa/entity/</value>
</list>
</property>
</bean>
3、创建dao、impl、biz包
4、a、创建applicationContext.xml-->Next-->CREATE SCHEMA FILE-->Next-->select xml catalog entry
找beans-->next-->root element 改beans 其他不打勾。然后把prefix的前缀p删了
add --> aop文件和tx文件
再添加p命名+context
b、spring接管hibernate的创建工厂（使用hibernate.cfg.xml文件的方法，添加一个bean sessionFactory 找localSessionFactoryBean）
注入一个属性 configLocation（ 当前配置）
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
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-3.2.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
<!--用dbcp的话，这段就不需要了，换成dataSource -->
<!-- sessionFatory工厂 -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>
</bean>
注入dao：
dao要工作的话，必须要一个sessionFactory（会话工厂），所以引用sessionFactory
dao继承hibernateDaoSupport就可以得到模板的属性，就可以使用getHibernateTemplate()方法
<!-- dao -->
<bean id="employeeDao" class="dao.impl.EmployeeDaoImpl">
<property name="sessionFatory" ref="sessionFactory"></property>
</bean>
注入biz：biz调用dao所以属性那是dao
<!-- 注入biz -->
<bean id="employeeBiz" class="biz.impl.EmployeeBizImpl">
<property name="employeeDao" ref="employeeDao"></property>
</bean>
事务：
首先声明事务（多加注意，很容易忘了）+事务管理器transaction-manager（事务管理器的要求增删改）
tx:advice事务属性的配置增删改 织入切面时候要引用id
<!-- 事务tx -->
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory"></bean>
<!-- 引用事务管理器 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="find*"/>//查询用read-only=“true"会比较快点
<tx:method name="get*"/>
<tx:method name="save*"/>
</tx:attributes>
</tx:advice>
织入切面：
<!-- 切面织入 -->
<aop:config>
<aop:pointcut expression="execution(public * biz.*.*(..))" id="serviceMethod"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod"/>
</aop:config>
接下去就是把业务层biz给action了
创建action和jsp界面
public class EmployeeAction {
//业务bean交给action
private EmployeeBiz employeeBiz;
//登录的话需要验证
private Employee employee;
//接收错误
private String message;
//set和get忽略
//登录
public String login(){
Employee result = employeeBiz.checkLogin(employee);
if(result == null){
this.message="用户名或密码错误";
return "input";
}else{
ActionContext.getContext().getSession().put("employee", result);
//职位
ActionContext.getContext().getSession()
.put("employee_position", result.getPosition().getNameEn());
return "success";
}
}
新建个struts.xml （头文件去struts2-spring-plugin-2.3.16.3.jar找struts-plugin.xml）
struts和spring合作的结果（EmployeeAction类里找到employeeBiz会去applicationContext.xml中去找一样名字的biz，就这样注入进去）
所以命名得规范，因为自动装配时靠名字对应的。否则就改成类型
<?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>
<package name="default" extends="struts-default" namespace="/">
<action name="login" class="action.EmployeeAction" method="login">
<result>/index.jsp</result>
<result name="input">/login.jsp</result>
</action>
</package>
</struts>
读取配置文件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_3_0.xsd" version="3.0">
<display-name></display-name>
<!-- web.xml就是读取配置文件 -->
<!-- 首先找配置文件在哪里 -->
<!-- (不是必须要的，如果文件放在并且名字也是applicationContext就不用配下面的文件路径在哪了/WEB-INF/applicationContext.xml) -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!-- 监听器 -->
<!-- 负责tomcat启动后创建ContextLoaderListener读取applicationContext文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 过滤器（为了控制会话） -->
<filter>
<filter-name>OpenSessionInViewFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
</filter>
<filter-mapping>//这个一定要放在struts2的映射前面，因为取决于谁在前，谁先执行
<filter-name>OpenSessionInViewFilter</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<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>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
就可以开始配置部署了。
