SpringBoot入门-6（利用jpa连接hibernate，并进行生成表，对表的增加，删除，查询操作）

1.在pom.xml加入jpa配置
<!-- 添加MySQL数据库驱动依赖包. -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

<!-- 添加Spring-data-jpa依赖. -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

2.在application.properties中配置mysql工作
spring.datasource.url = jdbc:mysql://localhost:3306/springboot_test
spring.datasource.username = root
spring.datasource.password = fengsi
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.max-active=20
spring.datasource.max-idle=8
spring.datasource.min-idle=8
spring.datasource.initial-size=10

3.在application.properties中配置jpa工作
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update
# Naming strategy
#[org.hibernate.cfg.ImprovedNamingStrategy  #org.hibernate.cfg.DefaultNamingStrategy]
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
# stripped before adding them to the entity manager)
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

4.编写测试例子
5.运行App.java启动
