springboot链接数据库

//pom.xml <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency>

属性文件配置application.properties

######################################################## ###datasource ######################################################## spring.datasource.url = jdbc:mysql://localhost:3306/test spring.datasource.username = root spring.datasource.password = root 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 ######################################################## ### Java Persistence Api ######################################################## # Specify the DBMS 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 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

新建实体测试

User.java package demo1.bean; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; /** * Created by LM on 2017/8/6. */ @Entity public class User{ @Id @GeneratedValue private long id; private String name; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

启动成功后，数据库会生成对应表
