【问题描述】：
我无法使用 PostgreSQL 数据库在 Heroku 上正确部署我的 Play Frmaework app (Java)。
Procfile
web: 目标/通用/stage/bin/name -Dhttp.port=${PORT} -DapplyEvolutions.default=true -Ddb.default.driver=org.postgresql.Driver -Ddb.default.url=$DATABASE_URL
built.sbt：
name := """name"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava)
scalaVersion := "2.11.1"
libraryDependencies ++= Seq(
javaJdbc,
javaEbean,
cache,
javaWs
)
libraryDependencies += "org.postgresql" % "postgresql" % "9.3-1100-jdbc4"
Heroku 的日志：

我特别不明白这个日志行
00:00 app[web.1]:←[0m [←[31merror←[0m] 播放 - 错误：键入“double” 不存在
当然，我的一些项目类中有一些双重属性。为什么double类型会出错？
任何建议/想法都非常受欢迎:)

这是我使用double 类型的仅有的两个类。
汽车
@Entity
public class Car extends Model{
@Id
@GeneratedValue
private int id;
@ManyToOne
@JoinColumn(name="user_fk")
private User user;
private String brand;
private String model;
@Column(unique = true)
private String licencePlate;
private String fuel;
private int nbSits;
@Column(name = "avg_cons", columnDefinition = "REAL")
private double avgCons; // Average consumption
@Column(name = "co2_cons", columnDefinition = "REAL")
private double co2Cons;
@Column(name = "htva_price", columnDefinition = "REAL")
private double htvaPrice;
@Column(name = "leasing_price", columnDefinition = "REAL")
private double leasingPrice;
@Column(columnDefinition = "REAL")
private double mileage;
@Column(columnDefinition = "REAL")
private boolean availability;
}
交易
@Entity
@Table(name = "transactions")
public class Transaction extends Model{
@Id
@GeneratedValue
private int id;
@OneToOne
@JoinColumn(name = "car_fk")
private Car car;
@OneToOne
@JoinColumn(name = "driver")
private User driver;
@Column(name = "from_date")
private Timestamp fromDate;
@Column(name = "to_date")
private Timestamp toDate;
@Column(name = "start_mileage", columnDefinition = "REAL")
private double startMileage;
@Column(name = "end_mileage", columnDefinition = "REAL")
private double endMileage;
@Column(columnDefinition = "REAL")
private double avgCons;
private String status;
private boolean exchange;
}
【问题讨论】：
-
您能否发布发出此错误的 DDL 语句部分。它应该在您的一个演变 *.sql 文件中（可能是 1.sql）。也许还有对应的Java模型类
-
我会在周日做，因为那时我没有计算机访问权限。
-
@Anton 我更新了我的问题。我看了一下 1.sql ，它只不过是经典的创建表脚本。
