Spring JPA不会在架构或MySql db下创建表。
#DataSource
spring.datasource.url=jdbc:mysql://localhost:3306/pickalystoredatabase?autoReconnect=true&useSSL=false
spring.datasource.username=root
spring.datasource.password=root
# Keep the connection alive if idle for a long time (needed in production)
spring.datasource.testWhileIdle = true
spring.datasource.validationQuery = SELECT 1
# 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
# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager)
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
应用程序属性似乎很完美。我也没有在日志中看到任何错误
@Entity
@Table(name = "user")
public class User {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "id", nullable = false, updatable = false)
private Long id;
@Column(name = "username", nullable = false)
private String username;
@Column(name = "password", nullable = false)
private String password;
@Column(name = "firstname", nullable = false)
private String firstname;
@Column(name = "lastname", nullable = false)
private String lastname;
@Column(name = "email", nullable = false, updatable = false)
private String email;
@Column(name = "phone", nullable = false)
private String phone;
@Column(name = "enabled", nullable = false)
private boolean enabled = true;
public User() { }
//getters snad setters
}
我正在使用spring-boot-started-data-jpa maven依赖项。版本1.5.9 RC。
记录供您参考
日志不会显示任何异常，也没有任何有关表创建的信息。

请帮忙。
编辑：
除了上面提到的属性，我还使用了属性和注释，如
@EnableAutoConfiguration
@EntityScan(basePackages = {"com.pickaly.domains"})
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect instead of MySQLDBDialect
但这些配置不起作用。
答案 0 :(得分：0)
尝试将spring.jpa.generate-ddl = true添加到您的应用程序属性中。
