springboot整合jpa组件

1.首先创建maven 工程

2.向pom 文件中添加依赖

 
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
<relativePath /> 
</parent>
<properties>
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
     <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
     <java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<!-- 整合mybatis -->

</dependency>

</dependency>
<dependency>

<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
</dependencies>

3.配置appliction.properties

#配置数据源

spring.datasourc.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.url=jdbc:mysql://localhost:3306/student

spring.datasource.username=root

spring.datasource.password=root

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#配置hiberate

spring.jpa.database=MYSQL

spirng.jpa.showsql=true

spring.jpa.hibernate.ddl-auto=update

spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

#配置页面映射

spring.mvc.view.prefix=/WEB-INF/jsp/

spring.mvc.view.suffix=.jsp

4.添加hibernate的配置文件 hibernate.cfg.xml 和 student.hbm.xml(这步省略,)

5.创建接口

@Repository

@Qualifier("studentDao")

public interface StudentDao extends JpaRepository<Student,Integer>{

}

接下来直接调用注入就可以了，非常方便。
