示例代码：http://download.csdn.net/detail/u010476739/9922870

工具：maven、spring framework4、hibernate4、postgresql

1.准备数据库，使用postgresql

 

CREATE TABLE Student( ID SERIAL PRIMARY Key, NAME VARCHAR(20) NOT NULL, AGE INT NOT NULL );

2.新建项目，添加依赖

 

<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>com.jackletter</groupId> <artifactId>spring-hibernate</artifactId> <version>0.0.1-SNAPSHOT</version> <name>this is name</name> <description>this is desc</description> <properties> <spring.version>4.2.4.RELEASE</spring.version> <postgresql.version>9.1-901.jdbc4</postgresql.version> <hibernate.version>4.3.11.Final</hibernate.version> </properties> <dependencies> <!-- Spring Core --> <!-- http://mvnrepository.com/artifact/org.springframework/spring-core --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <!-- Spring Context --> <!-- http://mvnrepository.com/artifact/org.springframework/spring-context --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-jdbc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <!-- Spring Aop --> <!-- http://mvnrepository.com/artifact/org.springframework/spring-aop/4.3.4.RELEASE --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.10</version> </dependency> <dependency> <groupId>postgresql</groupId> <artifactId>postgresql</artifactId> <version>${postgresql.version}</version> </dependency> <!-- Hibernate4 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>${hibernate.version}</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>${hibernate.version}</version> </dependency> </dependencies> </project>

 

 

 

3.spring配置（applicationContext.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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"> <context:component-scan base-package="bean" /> <!-- Initialization for data source --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="org.postgresql.Driver" /> <property name="url" value="jdbc:postgresql://localhost:5432/Demo" /> <property name="username" value="postgres" /> <property name="password" value="huqingjie123" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" lazy-init="false"> <!-- 注入datasource，给sessionfactoryBean内setdatasource提供数据源 --> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:hibernate.cfg.xml"></property> <!-- //加载实体类的映射文件位置及名称 --> <property name="mappingLocations" value="classpath:bean/*.hbm.xml"></property> </bean> <!-- 配置Spring声明式事务 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean> <!-- 配置事务事务属性 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="get*" read-only="true"/> <tx:method name="*"/> </tx:attributes> </tx:advice> <!-- 配置事务切点，并把切点和事务属性关联起来 --> <aop:config> <aop:pointcut expression="execution(* bean.StudentDAO.*(..))" id="txPointcut"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/> </aop:config> </beans>

 

4.hibernate配置

 

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- 配置Hibernate的基本属性 --> <!-- 1.数据源配置到IOC容器中 --> <!-- 2.关联的.hbm.xml也在IOC容器配置SessionFactory实例 --> <!-- 3.配置Hibernate的基本属性：方言，SQL显示及格式化，生成数据表的策略以及二级缓存 --> <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property> <property name="hibernate.show_sql">true</property> <property name="hbm2ddl.auto">update</property> </session-factory> </hibernate-configuration>

 

5.代码

 

Student

 

package bean; import javax.persistence.Entity; @Entity public class Student { private Integer age; private String name; private Integer id; public Student(Integer age, String name) { super(); this.age = age; this.name = name; } public void setAge(Integer age) { this.age = age; } public Integer getAge() { return age; } public void setName(String name) { this.name = name; } public String getName() { return name; } public void setId(Integer id) { this.id = id; } public Integer getId() { return id; } }

StudentDAO

 

package bean; public interface StudentDAO { public String findStudentById(int id); public void saveStudent(Student student); }

 

StudentDaoImpl

 

 

package bean; import org.hibernate.Query; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Repository; @Repository public class StudentDaoImpl implements StudentDAO { @Autowired private SessionFactory sessionFactory; // 获取和当前线程绑定的Seesion private Session getSession() { return sessionFactory.getCurrentSession(); } public String findStudentById(int id) { String hql = "SELECT name from Student where id=?"; Query query = getSession().createQuery(hql).setInteger(0, id); String str = query.uniqueResult().toString(); return str; } public void saveStudent(Student student) { getSession().save(student); } }

StudentService

 

package bean; public interface StudentService { public String findStudentById(int id); public void saveStudent(Student student); }

 

StudentServiceImpl

 

 

package bean; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @Service public class StudentServiceImpl implements StudentService { @Autowired private StudentDAO studentDao; public String findStudentById(int id) { return studentDao.findStudentById(id); } public void saveStudent(Student book) { studentDao.saveStudent(book); } }

 

App

 

 

package springhibernate; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import bean.Student; import bean.StudentService; public class App { public static void main(String[] args) { ApplicationContext context= new ClassPathXmlApplicationContext("applicationContext.xml"); StudentService srv=context.getBean(StudentService.class); srv.saveStudent(new Student(25,"lisa")); srv.saveStudent(new Student(27,"xiaogang")); srv.saveStudent(new Student(30,"tom")); srv.saveStudent(new Student(18,"jack")); String studentName=srv.findStudentById(1); System.out.println(studentName); } }
