我试图创建一个春天开机app.Getting以下无差错org.postgresql.util.PSQLException：ERROR：关系“后”不存在
org.postgresql.util.PSQLException: ERROR: relation "post" does not exist
当我尝试从运行eclipse.I最初得到hibernate_sequence错误，但通过查看后，我看到了@GeneratedValue（strategy = GenerationType.IDENTITY）解决方案。
这里是我的代码
是 -package au.com.riosoftware.firstapp.domain;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
public class Post {
private static final long serialVersionUID = -7049957706738879274L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private long id;
private String message;
public Post(){
}
public Post(String message){
this.message = message;
}
public long getId() {
return id;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}

我application.properties设置原样
我Post类
spring.jpa.database=postgresql
spring.datasource.platform=postgres
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.database.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb
spring.datasource.username=postgres
spring.datasource.password=postgres
server.port=8080
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR
任何想法为什么发生这种情况
