一、導入jar包java
能夠在src下添加一個log4j.properties文件來記錄日誌web
二、加入實體類+映射文件spring
映射:從類入手class+屬性sql
a、映射的頭文件在:hibernate3.jar-->org.hibernate-->hibernate-mapping-3.0.dtdexpress
b、type=「java.lang.String"根據屬性來更改+column(加長度的時候要獨立出來)apache
注意:若是有遇到entity not found 就要想到路徑錯誤,映射文件中有那個package=」包名「還有就是在hibernate.cfg.xml的mappling那路徑有沒有正確tomcat
<?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"> <id name="id" type="long"> <column name="id" /> <generator class="native" /> </id> <property name="sheetType" type="string"> <column name="sheet_type" length="20" not-null="true"> <comment>單據類型</comment> </column> </property> <property name="sheetId" type="long"> <column name="sheet_id" not-null="true"> <comment>單據編號</comment> </column> </property> <property name="checkTime" type="date"> <column name="check_time" length="19" not-null="true"> <comment>審覈時間</comment> </column> </property> <property name="type" type="string"> <column name="type" length="20" not-null="true"> <comment>審覈類型</comment> </column> </property> <many-to-one name="checker" class="Employee" fetch="select"> <column name="checker_sn" length="20" not-null="true"> <comment>審覈人</comment> </column> </many-to-one> <property name="result" type="string"> <column name="result" length="20" not-null="true"> <comment>審覈結果</comment> </column> </property> <property name="comment" type="string"> <column name="comment"> <comment>審覈意見</comment> </column> </property> </class> </hibernate-mapping>
hibernate.cfg.xml文件。頭文件在:hibernate3.jar-->org.hibernate-->hibernate-configuration-3.0.dtdsession
<?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oracle
先配置dataSource找BasicDataSourceapp
而後在注入sessionFactory
applicationContext.xml文件剛開始寫入下面的代碼
<!-- 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> <!-- 最大鏈接數是100 --> <property name="maxActive" value="100"></property> <!-- 最大空閒數是10 --> <property name="maxIdle" value="10"></property> <!-- 最大等待時間毫秒爲單位 --> <property name="maxWait" value="10000"></property> </bean> <!-- SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <!-- hibernateProperties 輔助參數 --> <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> <!-- 文件太多的話,不適合用 --> <!-- <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> --> <!-- 指定的包的路徑 、找包下全部的映射文件--> <property name="mappingDirectoryLocations"> <list> <value>classpath:cn/bdqn/jboa/entity/</value> </list> </property> </bean>
三、建立dao、impl、biz包
四、a、建立applicationContext.xml-->Next-->CREATE SCHEMA FILE-->Next-->select xml catalog entry
找beans-->next-->root element 改beans 其餘不打勾。而後把prefix的前綴p刪了
add --> aop文件和tx文件
再添加p命名+context
b、spring接管hibernate的建立工廠(使用hibernate.cfg.xml文件的方法,添加一個bean sessionFactory 找localSessionFactoryBean)
注入一個屬性 configLocation( 當前配置)
<?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的話,這段就不須要了,換成dataSource --> <!-- sessionFatory工廠 --> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> </bean>
注入dao:
dao要工做的話,必需要一個sessionFactory(會話工廠),因此引用sessionFactory
dao繼承hibernateDaoSupport就能夠獲得模板的屬性,就可使用getHibernateTemplate()方法
<!-- dao --> <bean id="employeeDao" class="dao.impl.EmployeeDaoImpl"> <property name="sessionFatory" ref="sessionFactory"></property> </bean>
注入biz:biz調用dao因此屬性那是dao
<!-- 注入biz --> <bean id="employeeBiz" class="biz.impl.EmployeeBizImpl"> <property name="employeeDao" ref="employeeDao"></property> </bean>
事務:
首先聲明事務(多加註意,很容易忘了)+事務管理器transaction-manager(事務管理器的要求增刪改)
tx:advice事務屬性的配置增刪改 織入切面時候要引用id
<!-- 事務tx --> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory"></bean> <!-- 引用事務管理器 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="find*"/>//查詢用read-only=「true"會比較快點 <tx:method name="get*"/> <tx:method name="save*"/> </tx:attributes> </tx:advice>
織入切面:
<!-- 切面織入 --> <aop:config> <aop:pointcut expression="execution(public * biz.*.*(..))" id="serviceMethod"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="serviceMethod"/> </aop:config>
接下去就是把業務層biz給action了
建立action和jsp界面
public class EmployeeAction { //業務bean交給action private EmployeeBiz employeeBiz; //登陸的話須要驗證 private Employee employee; //接收錯誤 private String message;
//set和get忽略
//登陸
public String login(){ Employee result = employeeBiz.checkLogin(employee); if(result == null){ this.message="用戶名或密碼錯誤"; return "input"; }else{ ActionContext.getContext().getSession().put("employee", result); //職位 ActionContext.getContext().getSession() .put("employee_position", result.getPosition().getNameEn()); return "success"; } }
新建個struts.xml (頭文件去struts2-spring-plugin-2.3.16.3.jar找struts-plugin.xml)
struts和spring合做的結果(EmployeeAction類裏找到employeeBiz會去applicationContext.xml中去找同樣名字的biz,就這樣注入進去)
因此命名得規範,由於自動裝配時靠名字對應的。不然就改爲類型
<?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>
讀取配置文件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就是讀取配置文件 --> <!-- 首先找配置文件在哪裏 --> <!-- (不是必需要的,若是文件放在而且名字也是applicationContext就不用配下面的文件路徑在哪了/WEB-INF/applicationContext.xml) --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 監聽器 --> <!-- 負責tomcat啓動後建立ContextLoaderListener讀取applicationContext文件--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 過濾器(爲了控制會話) --> <filter> <filter-name>OpenSessionInViewFilter</filter-name> <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class> </filter> <filter-mapping>//這個必定要放在struts2的映射前面,由於取決於誰在前,誰先執行 <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>
就能夠開始配置部署了。
