- 背景：
本文主要介紹使用spring-framework-4.3.8.RELEASE與hibernate-release-5.2.9.Final項目整合搭建的過程。
開發環境簡介：
1）、jdk 1.8
2）、spring-framework-4.3.8.RELEASE、hibernate-release-5.2.9.Final
- 引入Spring到新建項目My-SSH中
1）導入Spring的required包到My-SSH項目
新建java的dynamic web 項目，之後把spring-framework-4.3.8.RELEASE\libs下的發布包（*-4.3.8.RELEASE.jar，只拷貝這一種即可）拷貝到WebContent\WEB-INF\lib下。
除了spring的開發包外，在運行spring時，必須依賴commons-logging包，因此從http://commons.apache.org/proper/commons-logging/download_logging.cgi下載最新的commons-logging包，解壓後把包commons-logging-1.2-bin\commons-logging-1.2\commons-logging-1.2.jar拷貝到WebContent\WEB-INF\lib下。
2）配置WebContent\WEB-INF\web.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" 3 version="3.0"> 4 <display-name>My-SSH</display-name> 5 6<welcome-file-list> 7 <welcome-file>index.html</welcome-file> 8 <welcome-file>index</welcome-file> 9 </welcome-file-list> 10 11 <!-- 配置啟動IOC容器的Listener --> 12 <!-- needed for ContextLoaderListener --> 13 <context-param> 14 <param-name>contextConfigLocation</param-name> 15 <param-value>classpath:applicationContext.xml</param-value> 16 </context-param> 17 18 <!-- Bootstraps the root web application context before servlet initialization --> 19 <listener> 20 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 21 </listener> 22 </web-app>
3）在My-SSH項目根路徑下創建conf（Source Folder）文件夾，並添加spring配置文件applicationContext.xml
註意：
在新建該文件時，需要設定namespace包括：aop,beans,context,tx。
- 整合Hibernate到My-SSH項目，並與Spring整合
1）導入Hibernate的required包到My-SSH項目
把Hibernate開發包解壓路徑hibernate-release-5.2.9.Final\lib\required\下的所有包拷貝到WebContent\WEB-INF\lib下;
引入C3P0開發包，把hibernate-release-5.2.9.Final\lib\optional\c3p0\下的所有包拷貝到WebContent\WEB-INF\lib下。
2）在My-SSH項目根目錄下的conf文件中，新建hibernate配置文件hibernate.cfg.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <!DOCTYPE hibernate-configuration PUBLIC 3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 5 <hibernate-configuration> 6 <session-factory> 7 <!-- 8 把一下配置信息轉移到jdbc.properties中。 9 <property name="hibernate.connection.username">root</property> 10 <property name="hibernate.connection.password">123456</property> 11 <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> 12 <property name="hibernate.connection.url">jdbc:mysql://localhost/my_ssh</property> 13 --> 14 15 <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> 16 <property name="hibernate.show_sql">true</property> 17 <property name="hibernate.format_sql">true</property> 18 <property name="hibernate.hbm2ddl.auto">update</property> 19 <property name="hibernate.current_session_context_class">thread</property> 20 </session-factory> 21 </hibernate-configuration>
3）在My-SSH項目根目錄下的conf文件中，新建jdbc.properties文件
#----------------------------------------------------- # \u6570\u636E\u5E93\u914D\u7F6E #----------------------------------------------------- #\u670D\u52A1\u5668\u5730\u5740 host=127.0.0.1 dbName=my_ssh jdbc.driverClassName=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://${host}:3306/${dbName} jdbc.username=root jdbc.password=123456 #----------------------------------------------------- # \u9002\u7528\u4E8Ec3p0\u7684\u914D\u7F6E #----------------------------------------------------- #----------------------------------------------------- # c3p0\u53CD\u7A7A\u95F2\u8BBE\u7F6E\uFF0C\u9632\u6B628\u5C0F\u65F6\u5931\u6548\u95EE\u989828800 #----------------------------------------------------- #idleConnectionTestPeriod\u8981\u5C0F\u4E8EMySQL\u7684wait_timeout jdbc.c3p0.testConnectionOnCheckout=false jdbc.c3p0.testConnectionOnCheckin=true jdbc.c3p0.idleConnectionTestPeriod=3600 #----------------------------------------------------- # c3p0\u8FDE\u63A5\u6C60\u914D\u7F6E #----------------------------------------------------- #initialPoolSize, minPoolSize, maxPoolSize define the number of Connections that will be pooled. #Please ensure that minPoolSize <= maxPoolSize. #Unreasonable values of initialPoolSize will be ignored, and minPoolSize will be used instead. jdbc.c3p0.initialPoolSize=10 jdbc.c3p0.minPoolSize=10 jdbc.c3p0.maxPoolSize=100 #maxIdleTime defines how many seconds a Connection should be permitted to go unused before being culled from the pool. jdbc.c3p0.maxIdleTime=3600 #----------------------------------------------------- # hibernate\u8FDE\u63A5\u6C60\u914D\u7F6E #----------------------------------------------------- hibernate.connection.driverClass=com.mysql.jdbc.Driver hibernate.connection.url=jdbc:mysql://${host}:3306/${dbName} hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect hibernate.show_sql=true hibernate.format_sql=true hibernate.hbm2ddl.auto=update
4）通過配置My-SSH項目根目錄下的conf下的applicationContext.xml文件，將hibernate集成到spring中
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> <!-- 加載配置文件 --> <context:property-placeholder location="classpath:jdbc.properties" file-encoding="utf-8" ignore-unresolvable="true" /> <!-- 配置數據源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driverClassName}"></property> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> <property name="testConnectionOnCheckout" value="${jdbc.c3p0.testConnectionOnCheckout}"></property> <property name="testConnectionOnCheckin" value="${jdbc.c3p0.testConnectionOnCheckin}"></property> <property name="idleConnectionTestPeriod" value="${jdbc.c3p0.idleConnectionTestPeriod}"></property> <property name="initialPoolSize" value="${jdbc.c3p0.initialPoolSize}"></property> <property name="minPoolSize" value="${jdbc.c3p0.minPoolSize}"></property> <property name="maxPoolSize" value="${jdbc.c3p0.maxPoolSize}"></property> <property name="maxIdleTime" value="${jdbc.c3p0.maxIdleTime}"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <!-- 數據源dataSource --> <property name="dataSource" ref="dataSource" /> <!-- hibernate的配置方案一 --> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> <!-- hibernate的配置方案二 --> <!-- <property name="hibernateProperties"> <props> <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">${hibernate.format_sql}</prop> <prop key="hibernate.temp.use_jdbc_metadata_defaults">false</prop> </props> </property> --> <!-- 持久化類的位置方案一，通過包進行掃描 --> <property name="mappingLocations" value="classpath:com/dx/ssh/entities/*.hbm.xml"></property> <!-- spring的spring.jar的jar包內，在org.springframework.orm.hibernate3.annotation下， 有一個AnnotationSessionFactoryBean類，其中有一個屬性叫做"packagesToScan"， 有個方法叫setpackagesToScan()， 也就是說我可以再spring裏面將這個屬性給設定上。 packagesToScan是"包掃描"的意思，哪些包spring可以給我們掃描一下，看看有哪些實體類， 這一項在我們在配置文件中配置hibernate的實體類的時候可以這麽配，只要給出具體的掃描範圍就可以了， 不需要將實體類一個一個的寫出來 --> <!-- 持久化類的位置方案二，通過包進行掃描 --> <!-- <property name="packagesToScan"> <list> <value>com.dx.ssh.entities</value> </list> </property> --> <!-- 持久化類的位置方案三，通過類進行掃描 --> <!-- <property name="annotatedClasses"> <list> <value>com.dx.ssh.entities.Member</value> <value>com.dx.ssh.entities.Log</value> </list> </property> --> </bean> <!-- 配置Hibernate事務管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事務異常封裝 --> <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> <!-- 基於數據源的事務管理器 --> <!-- <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> --> <!-- 第一種方式: 註解方式配置事物 --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans>
- 測試是否集成成功
在My-SSH項目的src下新建包com.dx.ssh.entities，在包內添加Member及Member.hbm.xml
Member.java
1 package com.dx.ssh.entities; 2 3 public class Member { 4 private Integer id; 5 private String name; 6 7 public Integer getId() { 8 return id; 9 } 10 11 public void setId(Integer id) { 12 this.id = id; 13 } 14 15 public String getName() { 16 return name; 17 } 18 19 public void setName(String name) { 20 this.name = name; 21 } 22 }View Code
Member.hbm.xml
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 3 "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 4 <!-- Generated 2017-5-5 23:51:42 by Hibernate Tools 3.5.0.Final --> 5 <hibernate-mapping> 6 <class name="com.dx.ssh.entities.Member" table="MEMBER"> 7 <id name="id" type="java.lang.Integer"> 8 <column name="ID" /> 9 <generator class="native" /> 10 </id> 11 <property name="name" type="java.lang.String"> 12 <column name="NAME" /> 13 </property> 14 </class> 15 </hibernate-mapping>
運行項目，如果項目啟動沒有錯誤，並且在mysql新建的數據my_ssh庫中包含表MEMBE，就說明集成成功。
