我是春天的新手。当我启动应用程序时,它可以很好地启动,但是不会生成表模式。我不知道我是否犯了错误或是否有配置要做
SpringBootApplication
package org.opendevup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TpSpringMvcApplication {
public static void main(String[] args) {
SpringApplication.run(TpSpringMvcApplication.class, args);
}
}
application.properties
spring.datasource.url=jdbc:mysql://localhost:3306/db_sco_mvc
spring.datasource.username=******
spring.datasource.password=******
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
server.port = 3647
实体
package org.opendevup.entities;
import java.io.Serializable;
import java.util.Date;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
public class Etudiant implements Serializable{
@Id
@GeneratedValue
private Long id;
private String nom;
private Date dateNaissance;
private String email;
private String photo;
public Etudiant() {
super();
// TODO Auto-generated constructor stub
}
public Etudiant(String nom, Date dateNaissance, String email, String photo) {
super();
this.nom = nom;
this.dateNaissance = dateNaissance;
this.email = email;
this.photo = photo;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getNom() {
return nom;
}
public void setNom(String nom) {
this.nom = nom;
}
public Date getDateNaissance() {
return dateNaissance;
}
public void setDateNaissance(Date dateNaissance) {
this.dateNaissance = dateNaissance;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPhoto() {
return photo;
}
public void setPhoto(String photo) {
this.photo = photo;
}
}
注意:我更改了Tomcat的端口,因为端口8080被另一个进程使用,并且我已经创建了数据库: db_sco_mvc 。
我正在使用maven进行依赖。
最诚挚的问候。

为了创建表和架构,请执行以下操作:
添加@Entity
,实现Serializable接口,并为您的实体对象创建默认的和全参数的构造函数。
在application.properties
中,使用以下配置:
# Mysql
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://myurl/myschema?createDatabaseIfNotExist=true
spring.datasource.username=user
spring.datasource.password=pass
# Hibernate
spring.datasource.platform=mysql
spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.hibernate.ddl-auto=update
spring.data.jpa.repositories.enabled=true

还要在您的应用程序中添加以下配置:
spring.jpa.generate-ddl=true
对于ddl-auto,您可以继续使用update或尝试使用create-drop
spring.jpa.hibernate.ddl-auto = create-drop
