1.修改pom.xml
1. 添加 slf4j-api
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.0</version> </dependency>
2.添加 spring-orm
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.0.5.RELEASE</version> </dependency>
3.加入hibernate

配置dataSourceConfig.properties文件如下:
#hibernate.dialect=org.hibernate.dialect.OracleDialect #driverClassName=oracle.jdbc.driver.OracleDriver #validationQuery=SELECT 1 FROM DUAL #jdbc_url=jdbc:oracle:thin:@localhost:1521:orcl #jdbc_username=sypro #jdbc_password=sypro hibernate.dialect=org.hibernate.dialect.MySQLDialect driverClassName=com.mysql.jdbc.Driver validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/c_sai?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull jdbc_username=root jdbc_password= #hibernate.dialect=org.hibernate.dialect.SQLServerDialect #driverClassName=net.sourceforge.jtds.jdbc.Driver #validationQuery=SELECT 1 #jdbc_url=jdbc:jtds:sqlserver://127.0.0.1:1433/sy #jdbc_username=sa #jdbc_password=123456 #hibernate.dialect=org.hibernate.dialect.DerbyDialect #driverClassName=org.apache.derby.jdbc.EmbeddedDriver #validationQuery=SELECT 1 #jdbc_url=jdbc:derby:sy;create=true #jdbc_username=sypro #jdbc_password=sypro #jndiName=java:comp/env/dataSourceName hibernate.hbm2ddl.auto=update hibernate.show_sql=true hibernate.format_sql=true sessionInfoName=sessionInfo uploadFieldName=filedata uploadFileMaxSize=20971520 uploadFileExts=txt,rar,zip,doc,docx,xls,xlsx,jpg,jpeg,gif,png,swf,wmv,avi,wma,mp3,mid uploadDirectory=attached
测试类如下:
package com.sai.test.dao.impl; import javax.annotation.Resource; import javax.persistence.EntityManagerFactory; import org.springframework.orm.jpa.JpaTemplate; import org.springframework.orm.jpa.support.JpaDaoSupport; import org.springframework.stereotype.Repository; import com.sai.test.po.TTest; @Repository("TTestDAOImpl") public class TTestDAOImpl extends JpaDaoSupport implements TTestDAO { @Resource public void setMyEntityManagerFactory( EntityManagerFactory entityManagerFactory) { JpaTemplate jpaTemplate = new JpaTemplate(entityManagerFactory); super.setJpaTemplate(jpaTemplate); } @Override public TTest findById(Integer id) { return getJpaTemplate().find(TTest.class, id); } @Override public TTest save(TTest user) { getJpaTemplate().persist(user); return null; } }
service
package com.sai.test.service.impl; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.sai.test.dao.impl.TTestDAO; import com.sai.test.po.TTest; import com.sun.tools.internal.ws.wsdl.document.jaxws.Exception; @Service("TTestServiceImpl") public class TTestServiceImpl implements TTestService { @Resource private TTestDAO dao; @Override public TTest findById(Integer id) { TTest test = dao.findById(id); return test; } @Override public void save(TTest test) { dao.save(test); } @Override public void put(TTest test) { dao.save(test); } @Override public void save2(TTest test) throws Throwable { dao.save(test); if (1 == 1) throw new Throwable("bollback now !"); } }
测试类如下:
package test.jpa.tx; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.sai.test.dao.impl.TTestDAO; import com.sai.test.po.TTest; import com.sai.test.service.impl.TTestService; public class JPA_TX_Test { private static final String PATH = "spring-*.xml"; private static final String APPLICATION = "spring-application-jpa-customDataSource.xml"; private static final ApplicationContext ac = new ClassPathXmlApplicationContext( PATH); TTestService t = (TTestService) ac.getBean("TTestServiceImpl"); @Test public void support() { try { TTestDAO t = (TTestDAO) ac.getBean("TTestDAOImpl"); Object obj = t.findById(1); System.out.println("TTestDAOImpl.findById : "+obj); } catch (Exception e) { e.printStackTrace(); } } @Test public void txSupport() { try { Object obj = t.findById(1); TTest test = new TTest(); test.setUserName("put"); t.put(test); System.out.println("TTestServiceImpl.put : "+obj); } catch (Exception e) { e.printStackTrace(); } } @Test public void txRequired() { try { Object obj = t.findById(1); TTest test = new TTest(); test.setUserName("save"); t.save(test); System.out.println("TTestServiceImpl.save : "+obj); } catch (Exception e) { e.printStackTrace(); } } @Test public void txRequired2() { TTest test = new TTest(); try { test.setUserName("save2"); t.save2(test); } catch (Throwable e) { System.out.println("TTestServiceImpl.save2 : "+test); e.printStackTrace(); } } }
结果如下:
Hibernate: select ttest0_.id as id0_0_, ttest0_.userName as userName0_0_ from c_sai.t_test ttest0_ where ttest0_.id=? TTestDAOImpl.findById : TTest [id=1, userName=2] Hibernate: insert into c_sai.t_test (userName) values (?)

数据库记录如下:
| Id | username |
| 1 | 2 |
| 43 | save |
到此,在web.xml里面添加配置:
<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>Spring OpenEntityManagerInViewFilter</filter-name> <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> </filter> <filter-mapping> <filter-name>Spring OpenEntityManagerInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
最终效果如下:

到此,整合完毕
