一、整合原理
二、導包(41個)
1.hibernate
（1）hibernate/lib/required
?。?）hibernate/lib/jpa | java persist api java的持久化規(guī)范(接口)
?。?）數(shù)據(jù)庫驅(qū)動
2.struts2
?。?）struts-blank.war/WEB-INF/lib/*
注意:javassist-3.18.1-GA.jar包與hibernate中的重復（只保留高版本即可）
?。?）struts整合spring插件包
注意:這個包一旦導入,那么struts2在啟動時就會尋找spring容器.找不到將會拋出異常
3.spring
（1）基本:4+2
core | beans | context | expression | logging | log4j
?。?）整合web:web包
spring-web
?。?）整合aop:4個
spring-aop | spring-aspect | aop聯(lián)盟 | aopweaving
?。?）整合Hibernate和事務(wù):4個
spring-jdbc | spring-tx | c3p0 | spring-orm
?。?）整合junit4測試:test包
spring-test
4.標簽庫
standard.jar | jstl-1.2.jar
三、單獨配置spring容器
1.創(chuàng)建applicationContext.xml,并導入約束(4個) beans | context | aop | tx
<?xml version="1.0" encoding="UTF-8"?><beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd "> <bean name="userAction" class="cn.xyp.web.action.UserAction"></bean></beans>
2.配置spring隨項目啟動（web.xml）
<!-- 讓spring隨web啟動而創(chuàng)建的監(jiān)聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置spring配置文件位置參數(shù) --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param>
四、單獨配置struts2
1.配置struts2主配置文件（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>
<package name="crm" namespace="/" extends="struts-default">
<action name="UserAction_*" class="cn.xyp.web.action.UserAction" method="{1}">
<result name="success">/success.jsp</result>
</action>
</package></struts>
2.配置struts2核心過濾器到web.xml
<!-- struts2核心過濾器 --> <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>
五、struts2與spring整合
1.導包(已經(jīng)導入)
struts2-spring-plugin-2.3.24.jar
2.配置常量
查看默認配置文件從31行開始找到要配置的變量。
### if specified, the default object factory can be overridden here ### Note: short-hand notation is supported in some cases, such as "spring" ### Alternatively, you can provide a com.opensymphony.xwork2.ObjectFactory subclass name here # struts.objectFactory = spring ### specifies the autoWiring logic when using the SpringObjectFactory. ### valid values are: name, type, auto, and constructor (name is the default) struts.objectFactory.spring.autoWire = name
添加常量到struts.xml
<!-- # struts.objectFactory = spring 將action的創(chuàng)建交給spring容器 struts.objectFactory.spring.autoWire = name spring負責裝配Action依賴屬性 --> <constant name="struts.objectFactory" value="spring"></constant>
3.整合方案1:struts2自己創(chuàng)建action,spring負責組裝依賴屬性（了解）
<!-- 整合方案1:class屬性上仍然配置action的完整類名
struts2仍然創(chuàng)建action,由spring負責組裝Action中的依賴屬性 -->
<action name="UserAction_*" class="cn.xyp.web.action.UserAction" method="{1}" >
<result name="toHome" type="redirect" >/index.htm</result>
<result name="error" >/login.jsp</result>
</action>
不推薦理由:最好由spring完整管理action的生命周期.spring中功能才應(yīng)用到Action上.
4.整合方案2:spring負責創(chuàng)建action以及組裝.（推薦）
applicationContext.xml：
<!-- action --> <!-- 注意:Action對象作用范圍一定是多例的.這樣才符合struts2架構(gòu) --> <bean name="userAction" class="cn.itcast.web.action.UserAction" scope="prototype" > <property name="userService" ref="userService" ></property> </bean>
struts.xml：
<!--
整合方案2:class屬性上填寫spring中action對象的BeanName
完全由spring管理action生命周期,包括Action的創(chuàng)建
注意:需要手動組裝依賴屬性 -->
<action name="UserAction_*" class="userAction" method="{1}" >
<result name="toHome" type="redirect" >/index.htm</result>
<result name="error" >/login.jsp</result>
</action>
六、單獨配置hibernate
1.導入實體類&orm元數(shù)據(jù)
舉例：User.java
package cn.xyp.web.domain;import java.util.HashSet;import java.util.Set;public class User { private Long user_id; private String user_code; private String user_name; private String user_password; private Character user_state; public Long getUser_id() { return user_id;
} public void setUser_id(Long user_id) { this.user_id = user_id;
} public String getUser_code() { return user_code;
} public void setUser_code(String user_code) { this.user_code = user_code;
} public String getUser_name() { return user_name;
} public void setUser_name(String user_name) { this.user_name = user_name;
} public String getUser_password() { return user_password;
} public void setUser_password(String user_password) { this.user_password = user_password;
} public Character getUser_state() { return user_state;
} public void setUser_state(Character user_state) { this.user_state = user_state;
}
@Override public String toString() { return "User [user_id=" + user_id + ", user_code=" + user_code + ", user_name=" + user_name + ", user_password="
+ user_password + "]";
}
}
User.hbm.xml：
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping package="cn.xyp.domain" > <class name="User" table="sys_user" > <id name="user_id" > <generator class="native"></generator> </id> <property name="user_code" ></property> <property name="user_name" ></property> <property name="user_password" ></property> <property name="user_state" ></property> </class></hibernate-mapping>
2.配置主配置文件（hibernate.xml）
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration> <session-factory> <!-- 數(shù)據(jù)庫驅(qū)動 --> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <!-- 數(shù)據(jù)庫url --> <property name="hibernate.connection.url">jdbc:mysql:///crm_32</property> <!-- 數(shù)據(jù)庫連接用戶名 --> <property name="hibernate.connection.username">root</property> <!-- 數(shù)據(jù)庫連接密碼 --> <property name="hibernate.connection.password">1234</property> <!-- 數(shù)據(jù)庫方言 注意: MYSQL在選擇方言時,請選擇最短的方言. --> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> <!-- 將hibernate生成的sql語句打印到控制臺 --> <property name="hibernate.show_sql">true</property> <!-- 將hibernate生成的sql語句格式化(語法縮進) --> <property name="hibernate.format_sql">true</property> <!-- 自動導出表結(jié)構(gòu). 自動建表 --> <property name="hibernate.hbm2ddl.auto">update</property> <!-- 引入實體配置文件 --> <mapping resource="cn/xyp/domain/Customer.hbm.xml" /> <mapping resource="cn/xypt/domain/LinkMan.hbm.xml" /> <mapping resource="cn/xyp/domain/User.hbm.xml" /> </session-factory></hibernate-configuration>
七、spring整合hibernate
1.整合原理
將sessionFactory對象交給spring容器管理
2.在spring中配置sessionFactory
?。?）配置方案一:（了解）
<!-- 加載配置方案1:仍然使用外部的hibernate.cfg.xml配置信息 --> <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" > <property name="configLocation" value="classpath:hibernate.cfg.xml" ></property> </bean>
?。?）配置方案二:（推薦）
<!-- 加載配置方案2:在spring配置中放置hibernate配置信息 --> <bean name="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" > <!-- 將連接池注入到sessionFactory, hibernate會通過連接池獲得連接 --> <property name="dataSource" ref="dataSource" ></property> <!-- 配置hibernate基本信息 --> <property name="hibernateProperties"> <props> <!-- 必選配置 --> <prop key="hibernate.connection.driver_class" >com.mysql.jdbc.Driver</prop> <prop key="hibernate.connection.url" >jdbc:mysql:///crm_32</prop> <prop key="hibernate.connection.username" >root</prop> <prop key="hibernate.connection.password" >1234</prop> <prop key="hibernate.dialect" >org.hibernate.dialect.MySQLDialect</prop> <!-- 可選配置 --> <prop key="hib
