创建bean

import javax.persistence.Entity;

import javax.persistence.GeneratedValue;

import javax.persistence.Id;

import javax.persistence.Table;

/**

 * Created by Administrator on 2017/5/27 0027.

 */

@Entity

@Table

public class User {

    @Id @GeneratedValue

    private Integer user_id;

    private String user_name;

    private String password;

    private Integer age;

    //getter和setter

}

application.properties

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

spring.datasource.username = root

spring.datasource.password = root

spring.datasource.driverClassName = com.mysql.jdbc.Driver

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.properties.hibernate.hbm2ddl.auto=create-drop

# stripped before adding them to the entity manager)

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