springmvc,spring,hibernate框架整合
首先工作是匯入jar包
需要的jar包:
測試需要的jar包 junit
spring系列的jar包 spring-webmvc(spring-aop spring-beans spring-context spring-core spring-expression
spring-web)
spring-jdbc
spring-orm
aspectjweaver
aspectjrt
aopalliance aop切面
hibernate jar包 hibernate-core
hibernate-ehcache
連線資料庫的jar包 commons-logging
commons-dbcp(commons-pool)
mysql-connector-java
日誌的jar包 slf4j-api
slf4j-log4j12
log4j-core
檔案上傳 commons-fileupload
轉json fastjson
快取 ehcache
配置檔案

新增web目錄,配置web.xml
<?xml version="1.0" encoding="UTF-8"?>

新增資料庫連線配置檔案
db.properties
dbcp.driverClassName=com.mysql.jdbc.Driver
dbcp.url=jdbc:mysql://localhost:3306/onetomore
dbcp.username=root
dbcp.password=123456
dbcp.maxActive=100
dbcp.initialSize=5
在applicationContext.xml中配置讀取db.properties的配置
使用${}讀取檔案,這裡我前面加個字首,不然讀取不了,一定跟前面的name=“”不一樣就行
<!--從上下文環境中讀取db.properties配置檔案-->
<context:property-placeholder location="classpath*:db.properties"></context:property-placeholder>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${dbcp.driverClassName}"></property>
<property name="url" value="${dbcp.url}"></property>
<property name="username" value="${dbcp.username}"></property>
<property name="password" value="${dbcp.password}"></property>
<property name="maxActive" value="${dbcp.maxActive}"></property>
<property name="initialSize" value="${dbcp.initialSize}"></property>
</bean>
新增hibernate,生成實體類
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="connection.url">jdbc:mysql://localhost:3306/java1807</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.username">root</property>
<property name="connection.password">123456</property>
<!--資料庫表示什麼引擎,它就是什麼引擎-->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<!--顯示sql-->
<property name="hibernate.show_sql">true</property>
<!--美化sql,格式化sql語句-->
<property name="hibernate.format_sql">true</property>
<!--使用二級快取-->
<property name="hibernate.cache.use_second_level_cache">true</property>
<!--配置二級快取服務商-->
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>
<!--使用查詢快取-->
<property name="cache.use_query_cache">true</property>
<mapping resource="Area.hbm.xml"/>
<mapping resource="City.hbm.xml"/>
<mapping resource="Province.hbm.xml"/>
<!-- <mapping class="com.qy.domain.Province"></mapping>
<mapping class="com.qy.domain.City"></mapping>
<mapping class="com.qy.domain.Area"></mapping>-->
<!-- <property name="connection.username"/> -->
<!-- <property name="connection.password"/> -->
<!--配置讀寫-->
<class-cache class="com.qy.domain.Province" usage="read-write"></class-cache>
<!-- DB schema will be updated if needed -->
<!-- <property name="hbm2ddl.auto">update</property> -->
</session-factory>
</hibernate-configuration>
將hibernate和spring整合
刪除hibernate.cgf.xml檔案,把hibernate的檔案配置在application.xml中
<!-- 配置Hibernate的SessionFactory -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<!--指定當前會話工廠使用的資料來源-->
<property name="dataSource" ref="dataSource"></property>
<!--指定實體類的位置-->
<property name="packagesToScan" value="com.qy.domain"/>
<!-- <property name="annotatedClasses">
<list>
<value>com.qy.domain.Province</value>
</list>
</property>-->
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.show_sql=true
hibernate.format_sql=true
<!-- hibernate.hbm2ddl.auto=create -->
</value>
</property>
</bean>
總結
專案執行時,先讀取web.xml檔案,根據web.xml讀取到applicationContext.xml和springmvc-servlet.xml檔案,在springmvc-servlet檔案主要配置view層的東西,檢視解析器,返回json字串亂碼問題,檔案上傳,定義註解掃描的包,這裡只掃描controller層。applicationContext.xml中也要開始註解掃面,掃描的是除了controller層的其他層。讀取db.properties配置檔案,配置Hibernate的sessionFacory,替代hibernate.cfg.xml檔案,最後是配置事務的屬性,切入點。這樣框架就可以執行起來。可以在seivice層或者test中測試。
