Hibernate整合Spring（java專案）

1、首先需要建立一個maven的java專案，新增對應的依賴（4個Spring的依賴和一個hibernate的依賴）pom.xml檔案如下
儲存之後在手動buildpath新增ojdbc的驅動，之後會得到如下圖的jar檔案<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.iflytek</groupId> <artifactId>firstSpringHibernate</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.3.13.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.3.13.RELEASE</version> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>4.3.13.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.13.RELEASE</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.11.Final</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> </dependencies> </project>
2、新增配置檔案applicationContext.xml檔案，配置資料庫的驅動連線和sessionFactory的初始化物件
對應的還有其他屬性檔案，這裡還有用log4j.property的日誌檔案，列印日誌的，意義不大，所以不多做說明了。<?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" 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.xsd"> <!-- 配置可以使用Spring註解 --> <context:component-scan base-package="com.iflytek"></context:component-scan> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property> <property name="url" value="jdbc:oracle:thin:@172.16.130.35:1521:orcl"></property> <property name="username" value="uuid"></property> <property name="password" value="uuid"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <property name="packagesToScan" value="com.iflytek.domain"></property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> </props> </property> </bean> </beans>
3、寫java pojo的程式碼配置註釋生成對應的資料庫表
（也可以通過hbm.xml檔案配置資料表，但是需要在在ApplicationContext.xml檔案中配置sessionfatcory加上如下：
<property name="mappingResources">
<list>
<value>xxx/xxx/model/User.hbm.xml</value>
</list User類
package com.iflytek.domain;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
//把user物件建立（預設的名字為：物件的名字小寫），然後加入到容器中
@Entity
@Table(name="t_user1")
public class User {
private int id;
private String name;
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
UserService.java
package com.iflytek.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.iflytek.dao.UserDao;
@Service
public class UserService {
@Resource
private UserDao userDao;
public UserService() {
}
public UserService(UserDao userDao) {
this.userDao = userDao;
System.out.println("userservice construct run...");
}
}UserDao.java
package com.iflytek.dao;
import javax.annotation.Resource;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.stereotype.Repository;
import com.iflytek.domain.User;
@Repository
public class UserDao {
@Resource
private SessionFactory sessionFactory;
public void save() {
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
User user = new User();
user.setId(1001);
user.setName("testsaveuser");
session.save(user);
tx.commit();
session.close();
}
}測試類App.java
package com.iflytek.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.iflytek.dao.UserDao;
public class App {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
UserDao bean = context.getBean(UserDao.class);
bean.save();
}
}5、結果
會在資料庫中生成一張t_user1的資料表，新增一條id為1001的資料，如下圖
綜：存初學者個人學習，相互交流，不喜勿噴。
