首先咱们先创建一个maven工程
在pom.xml加入以下 依赖
<!--Mysql 驱动包--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework.data/spring-data-jpa --> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-jpa</artifactId> <version>1.11.6.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-entitymanager --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-entitymanager</artifactId> <version>5.2.9.Final</version> </dependency>
然后配置spring 文件
创建一个bean.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:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jpa="http://www.springframework.org/schema/data/jpa" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!--配置数据源--> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="username" value="root"/> <property name="password" value="123"/> <property name="url" value="jdbc:mysql:///springdata"/> </bean> <!--配置EntityManagerFactory--> <bean id = "entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/> </property> <property name="packagesToScan" value="org.springdata"/> <property name="jpaProperties"> <props> <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.ImprovedNamingStrategy</prop> <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> </props> </property> </bean> <!--3 配置事务管理器--> <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <!--4 配置支持注解的事务--> <tx:annotation-driven transaction-manager="transactionManager"/> <!--5 配置spring data--> <jpa:repositories base-package="org.springdata" entity-manager-factory-ref="entityManagerFactory"/> <context:component-scan base-package="org.springdata"/> </beans>
创建一个实体类 Employee.java 咱们可以通过JPA 的注解自动生成数据表
package org.springdata.domain; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; /** * 雇员: 先开发实体类===>自动生成数据表 */ @Entity public class Employee { private Integer id; private String name; private Integer age; @GeneratedValue @Id public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } @Column(length = 20) public String getName() { return name; } public void setName(String name) { this.name = name; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; } }
package org.springdata; import org.junit.After; import org.junit.Before; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; /** * 测试类 */ public class SpringDataTest { private ApplicationContext ctx = null; @Before public void setup(){ ctx = new ClassPathXmlApplicationContext("beans.xml"); System.out.println("setup"); } @After public void tearDown(){ ctx = null; System.out.println("tearDown"); } @Test public void testEntityManagerFactory(){ } }
创建一个测试类 如上 执行 出现绿色横条表示成功, 在到数据库去看下 是否成功创建一个employee表
好了 环境搭建就到这里啦 是不是很简单呢,关注走一走 活到九十九 老铁们 没毛病
