postgresql - Play Framework 2.6 中未触发 Slick (postgresql) 演变

Question

这里是数据库配置

应用程序配置文件:

slick.dbs.default.profile="slick.jdbc.PostgresProfile$"
slick.dbs.default.db.driver="org.postgresql.Driver"
slick.dbs.default.db.url="jdbc:postgresql://localhost:5432/postgres"
slick.dbs.default.db.user=postgres
slick.dbs.default.db.password=postgres

build.sbt

name := """myproject"""
version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

resolvers += Resolver.sonatypeRepo("snapshots")

scalaVersion := "2.12.4"

libraryDependencies += guice
libraryDependencies += evolutions

libraryDependencies += "org.scalatestplus.play" %% "scalatestplus-play" % "3.0.0" % Test


libraryDependencies += "org.postgresql" % "postgresql" % "42.1.4"
libraryDependencies += "com.typesafe.play" %% "play-slick" % "3.0.1"
libraryDependencies += "com.typesafe.play" %% "play-slick-evolutions" % "3.0.1"

我在 conf/evolutions/default 文件夹中有 sql 脚本

1.sql

# Users schema

# --- !Ups

CREATE TABLE users
(
    id bigint NOT NULL,
    email character varying(255) NOT NULL,
    username character varying(100) NOT NULL,
    password character varying(100) NOT NULL,       
    PRIMARY KEY (id)
)
WITH (
    OIDS = FALSE
);

# --- !Downs

DROP TABLE IF EXISTS users CASCADE;

但是在应用程序启动时，不会触发进化。数据库连接工作正常(我已经通过从这个应用程序对数据库实现一些巧妙的查询进行了检查)。

我在这里做错了什么？

尝试将这一行添加到您的 application.conf 中:

play.evolutions.db.default.enabled = true
