之前的一篇已经讲到了 spring 与struts2 的整合, 其实对于struts2+hibernate-jpa+Spring 之间的整合的文章已经相当多了,
也相当成熟了,只要不是各自的版本不兼容之外,其他的几乎没啥问题, 不行mybatis那样是不是的冒点让人头疼的事情来
下面修改pom.xml ,把hibernate 的jar 关联进来;
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>msshj</groupId> <artifactId>msshj</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name /> <description /> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> </properties> <dependencies> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.0</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.0.5.RELEASE</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.16</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.7.2</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>3.6.10.Final</version> <exclusions> <exclusion> <artifactId>slf4j-api</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>3.6.10.Final</version> <exclusions> <exclusion> <artifactId>slf4j-api</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency> <dependency> <groupId>com.alibaba.druid</groupId> <artifactId>druid-wrapper</artifactId> <version>0.2.9</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> </dependency> <!-- commons --> <dependency> <groupId>commons-beanutils</groupId> <artifactId>commons-beanutils</artifactId> <version>1.9.1</version> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3</version> </dependency> <!-- J2EE COMMONS --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet.jsp</groupId> <artifactId>jsp-api</artifactId> <version>2.1</version> <scope>provided</scope> </dependency> <dependency> <groupId>org.glassfish</groupId> <artifactId>javax.annotation</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.glassfish</groupId> <artifactId>javax.ejb</artifactId> <version>3.0.1</version> </dependency> <dependency> <groupId>org.glassfish</groupId> <artifactId>javax.servlet</artifactId> <version>3.0.1</version> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-war-plugin</artifactId> </plugin> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> <encoding>UTF-8</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <configuration> <charset>UTF-8</charset> </configuration> </plugin> </plugins> </build> </project>
添加spring-hibernate-jpa.xml的配置
<?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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:p="http://www.springframework.org/schema/p" xmlns:cache="http://www.springframework.org/schema/cache" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache-3.0.xsd"> <!-- 配置实体管理对象 p:persistenceUnitManager-ref="persistenceUnitManager" --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="classpath:/META-INF/persistence.xml" /> <property name="dataSource" ref="dataSource" /> <!-- 选配属性 --> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="MYSQL" /> <property name="showSql" value="true" /> <property name="generateDdl" value="true" /> <property name="databasePlatform" value="${hibernate.dialect}" /> </bean> </property> </bean> <!--可屏蔽 <bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager" p:default-data-source-ref="dataSource" p:persistence-xml-locations="classpath*:META-INF/persistence.xml"> <property name="loadTimeWeaver"> <bean class="org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver"/> </property> </bean> --> <bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <tx:annotation-driven transaction-manager="txManager" proxy-target-class="true" /> <!-- 定义使用事务的方法 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <tx:method name="add*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="append*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="insert*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="save*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="update*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="modify*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="edit*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="delete*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="remove*" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="repair" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="delAndRepair" propagation="REQUIRED" rollback-for="Throwable" /> <tx:method name="get*" propagation="SUPPORTS" rollback-for="Throwable" /> <tx:method name="find*" propagation="SUPPORTS" rollback-for="Throwable" /> <tx:method name="load*" propagation="SUPPORTS" rollback-for="Throwable" /> <tx:method name="search*" propagation="SUPPORTS" rollback-for="Throwable" /> <tx:method name="datagrid*" propagation="SUPPORTS" rollback-for="Throwable" /> <tx:method name="*" propagation="SUPPORTS" rollback-for="Throwable" /> </tx:attributes> </tx:advice> <!-- 定义 切入点，使事务在它的切入点内有效 --> <aop:config>
<aop:pointcut expression="within(com.sai..*.service.impl.*)" id="TXpointcut1" />
<aop:advisor pointcut-ref="TXpointcut1" advice-ref="txAdvice" />
</aop:config> </beans>
添加spring-datasource.xml
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- JNDI方式配置数据源 --> <!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> --> <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:dataSourceConfig.properties</value> </list> </property> </bean> <!-- 配置数据源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <property name="url" value="${jdbc_url}" /> <property name="username" value="${jdbc_username}" /> <property name="password" value="${jdbc_password}" /> <!-- 初始化连接大小 --> <property name="initialSize" value="1" /> <!-- 连接池最大使用连接数量 --> <property name="maxActive" value="20" /> <!-- 连接池最大空闲 --> <property name="maxIdle" value="20" /> <!-- 连接池最小空闲 --> <property name="minIdle" value="1" /> <!-- 获取连接最大等待时间 --> <property name="maxWait" value="60000" /> <!-- <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> --> <property name="validationQuery" value="${validationQuery}" /> <property name="testOnBorrow" value="false" /> <property name="testOnReturn" value="false" /> <property name="testWhileIdle" value="true" /> <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --> <property name="timeBetweenEvictionRunsMillis" value="60000" /> <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --> <property name="minEvictableIdleTimeMillis" value="25200000" /> <!-- 打开removeAbandoned功能 --> <property name="removeAbandoned" value="true" /> <!-- 1800秒，也就是30分钟 --> <property name="removeAbandonedTimeout" value="1800" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="true" /> <!-- 监控数据库 --> <!-- <property name="filters" value="stat" /> --> <property name="filters" value="mergeStat" /> </bean> </beans>
最后修改 web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <!-- contextConfigLocation --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/spring-*.xml</param-value> </context-param> <filter> <filter-name>encoding</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- OpenEntityManagerInViewFilter --> <filter> <filter-name>SpringOpenEntityManagerInViewFilter</filter-name> <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>SpringOpenEntityManagerInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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>*.cy</url-pattern> </filter-mapping> <display-name></display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
最后一点META-INF/persistence.xml 必须要有!
应为我是选择在自定义文件中配置数据源, 所以,这里面的内容必须为空,你也可以选择在这里配置你的数据源.但是可配置的属性比较少,但是胜在方便
<?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0"> <persistence-unit name="webUnit" transaction-type="RESOURCE_LOCAL"> <!-- <properties> --> <!-- <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /> --> <!-- <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/sshe?useUnicode=true&characterEncoding=UTF-8" /> --> <!-- <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /> --> <!-- <property name="hibernate.connection.username" value="root" /> --> <!-- <property name="hibernate.connection.password" value="123123" /> --> <!-- <property name="hibernate.max_fetch_depth" value="3" /> --> <!-- <property name="hibernate.jdbc.fetch_size" value="20" /> --> <!-- <property name="hibernate.jdbc.batch_size" value="10" /> --> <!-- <property name="hibernate.show_sql" value="true" /> --> <!-- <property name="hibernate.format_sql" value="true" /> --> <!-- <property name="hibernate.hbm2ddl.auto" value="update" /> --> <!-- <property name="hibernate.timeBetweenEvictionRunsMillis" --> <!-- value="12000" /> --> <!-- 每隔120秒检查连接池里的空闲连接 ，单位是秒 --> <!-- <property name="hibernate.minEvictableIdleTimeMillis" value="1200" /> --> <!-- </properties> --> </persistence-unit> </persistence>
整合到此结束, 启动即用,不再废话了!
