玩2.4 Framework和MySQL

时间：2015-08-28 17:21:29

标签： mysql playframework playframework-2.4

我无法使用MySqL处理Play 2.4

例如，如果我使用激活器创建一个基于＆＃34; play-java-intro＆＃34;模板 （请参阅下面的详细信息），对应video首页上显示的playframework.com， 到目前为止工作正常。然而，这是使用内存中的h2数据库。

当我尝试修改项目以使用mysql时，我得到＆＃34;执行异常＆＃34;：

当我尝试保存到数据库时。

＆＃34;的 CONF /演进/默认/ 1.SQL ＆＃34;确实被创建了，mysql数据库确实得到了合适的表 插入，但我似乎无法将任何行保存到表中。

我真的很感激解决方案。

非常感谢提前。

以下是我所做的以及我的代码：

（1）我有一个带有
的系统 OpenSuse 13.2 Linux，与Mariadb， Intellij 14， 播放2.4.2

mysql正在运行，并且有一个数据库＆＃34; foo_db＆＃34; 用户＆＃34; root＆＃34;使用空密码具有完全访问权限。

MariaDB [foo_db]> describe person_tb;
+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| id    | varchar(255) | NO   | PRI | NULL    |       |
| name  | varchar(255) | YES  |     | NULL    |       |

根据＆＃34; play-java-intro＆＃34;创建一个新的播放应用模板

> activator new play-java-intro_mysql play-java-intro
> cd my-play-java-sql
> activator run

点浏览器 http://localhost:9000/

该应用程序工作正常..可以添加＆＃34;人员＆＃34;等，如教程中所述。 video tutorial

（2）现在我修改一些文件以尝试使用mysql。

之后的文件下方

Person.java：

package models;

import javax.persistence.*;

@Entity
@Table(name = "person_tb")
public class Person {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public String id;

    public String name;

}

appplication.conf：

play.crypto.secret = "changeme"

play.i18n.langs = [ "en" ]

db.default.driver=com.mysql.jdbc.Driver
db.default.url="jdbc:mysql://localhost/foo_db"
db.default.username=root
db.default.password=""

ebean.default=["models.*"]
#applyEvolutions.default=true
db.default.jndiName=DefaultDS

jpa.default=defaultPersistenceUnit

build.sbt：

name := """play-java-intro_mysql"""
version := "1.0-SNAPSHOT"
lazy val root = (project in file(".")).enablePlugins(PlayJava, PlayEbean)

libraryDependencies ++= Seq(
  evolutions,
 javaJpa,
javaJdbc,
  "mysql" % "mysql-connector-java" % "5.1.18",
  "org.hibernate" % "hibernate-entitymanager" % "4.3.7.Final"
)

routesGenerator := InjectedRoutesGenerator

plugins.sbt：

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")

addSbtPlugin("com.typesafe.sbt" % "sbt-coffeescript" % "1.0.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-less" % "1.0.6")
addSbtPlugin("com.typesafe.sbt" % "sbt-jshint" % "1.0.3")
addSbtPlugin("com.typesafe.sbt" % "sbt-rjs" % "1.0.7")
addSbtPlugin("com.typesafe.sbt" % "sbt-digest" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")


addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

答案 0 :(得分：3)

“activator new”使用“play-java-intro”模板生成的代码不起作用（使用MySQL）。要使其工作，必须修改以下文件，如下所示：

应用/控制器/ Application.java 

package controllers;
import play.*;
import play.db.ebean.Transactional;
import play.mvc.*;
import views.html.*;
import models.Person;
import play.data.Form;
import java.util.List;
import static play.libs.Json.*;


public class Application extends Controller {

public Result index() {
    return ok(index.render());
}
@Transactional
public Result addPerson() {
    // Person person = Form.form(Person.class).bindFromRequest().get();
    // JPA.em().persist(person);
    Person person = Form.form(Person.class).bindFromRequest().get();
    person.save();
    return redirect(routes.Application.index());
}
@Transactional
public Result getPersons() {
  List<Person> persons  = Person.FIND.findList();
    //List<Person> persons = (List<Person>) JPA.em().createQuery("select p from Person p").getResultList();
    return ok(toJson(persons));
}

}

应用/模型/ Person.java 

package models;
import javax.persistence.*;
import com.avaje.ebean.Model;
@Entity
public class Person extends Model {
    @Id
    public Long id;

    public String name;
    public static Model.Finder<Long, Person> FIND = new Model.Finder<>(Person.class);
}

<强> build.sbt 

name := """play-java-intro_mysql"""

libraryDependencies ++= Seq(

   javaJdbc,
   javaJpa,
  "mysql" % "mysql-connector-java" % "5.1.18"
)

<强>项目/ plugins.sbt 

// The Play plugin
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")

addSbtPlugin("com.typesafe.sbt" % "sbt-mocha" % "1.1.0")

// Play enhancer - this automatically generates getters/setters for public fields
// and rewrites accessors of these fields to use the getters/setters. Remove this
// plugin if you prefer not to have this feature, or disable on a per project
// basis using disablePlugins(PlayEnhancer) in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-enhancer" % "1.1.0")

// Play Ebean support, to enable, uncomment this line, and enable in your build.sbt
addSbtPlugin("com.typesafe.sbt" % "sbt-play-ebean" % "1.0.0")

<强> CONF / application.conf 

play.crypto.secret = "changeme"

# The application languages
play.i18n.langs = [ "en" ]

ebean.default=["models.*"]
